Setting the Line for Sports Betting Revenue

EXECUTIVE SUMMARY

Recently, the sports betting legalization movement has gotten some welcome traction, with legislatures in several states taking a fresh look at the issue, and the commissioners of the professional sports leagues showing signs of increasing comfort with the legalization concept. In much of the media coverage of the issue, sports betting advocates use a financial pitch touting the massive revenue streams that could be realized from regulating the currently illicit sports betting market. Most of these financial projections seemed rather large, often claiming hundreds of billions of dollars in wagers would generate hundreds of millions in tax revenues. With the recent New Jersey online gaming boondoggle—where actual online gaming revenues have fallen woefully short of the projections touted by legalization supporters—I set out to research a short post analyzing the assumptions behind the sports legalization effort. As will come as no surprise to my dozen or so regular readers, my research resulted in a much longer piece.

In Part A—Introduction, I review a few examples of the common revenue projections touted by sports betting advocates. In Part B—Guesstimating the Illegal Sports Betting Market, I look at the common projections of the scope of the current illegal sports betting market and discover the most widely cited estimates are essentially bogus. In Part C—Conflating Amounts Wagered with Gaming Revenues and Tax Revenues, I analyze the common mathematical errors riddling many sports betting revenue projections, errors which generally result in a significant overestimate of potential revenue streams.

In Part D—Estimating the Potential Size of the Legal Sports Betting Market, I take a stab at generating my own back-of-the-envelope, wild-ass guess at the potential size of a legalized sports betting economy, and provide a couple of handy-dandy interactive spreadsheets so readers can generate and bedazzle their own revenue estimates. One interesting conclusion is that data from Nevada, currently the nation's only mature and saturated sports betting market, suggests that estimates for sports betting revenues in New Jersey and nationally may be wildly overstated (spoiler alert): "Applying the Nevada ratio to these historical revenue numbers would suggest New Jersey might reasonably expect somewhere between $59.8 million and $107.2 million in annual sports book revenues, which translates into $4.8 million to $8.6 million in additional annual tax revenues (applying the current 8% gaming tax rate)." Finally, in Part E—Market Issues: Expansion, Conversion, and Competition, I explore a few factors which further complicate any attempt to estimate the potential revenue streams from legalization of sports betting.

I enjoy placing the occasional recreational sports wager, usually in Vegas, sometimes with a friend, and occasionally through more traditional back channels. I am firmly in the Legalize-Regulate-Tax camp. But if sports betting legalization is going to be sold as a revenue generator, we owe it to the public to use solid data where available, and to appropriately flag and hedge estimates and assumptions which lack rigorous underlying research. Let's sell sports betting legalization on its merits, not like a bunch of carnival hucksters.

A.  Introduction

As the movement to legalize sports betting on a national basis gains momentum, an increasing number of public figures are finding ways to voice their support. NBA commissioner Adam Silver has led the charge, penning a New York Times op-ed piece and sitting for a prominent ESPN: The Magazine interview to advocate for a "realistic" debate about legalizing and regulating sports betting. The new MLB commissioner, Rob Manfred, similarly seems open to a discussion of legalized sports betting.

One of the primary arguments used by sports betting advocates is that legalization will lead to a gusher of tax revenues for cash-strapped state governments. In that vein, Florida sports talk show host and writer David Moulton penned an article in the News-Press asserting that legalization of sports betting would raise, "conservatively", $750 million in annual state tax revenues for Florida. In New Jersey, state officials have touted annual tax revenue projections ranging from $100 million to $120 million, and up to $166 million. Certainly these are eye-popping figures which might persuade skeptical voters to take a flyer on sports betting.

The problem with the tax revenue argument for gaming is that it is easy to promise revenues, but hard to deliver. New Jersey Governor Chris Christie famously promised new tax revenues of $200 million in the first year of legalized online gaming. As has been well-documented, actual revenues fell more than $150 million short of projections. Even worse, gaming industry analysts have revised their best-case long-term revenue projections to fall significantly below the projections used by online gaming advocates to support their case for legalization.

The New Jersey online gaming revenue debacle is a cautionary tale as the sports betting legalization debate heats up. Yet sports betting advocates repeatedly cite financial figures which are confusing at best and misleading at worst. How can we present the public with more accurate revenue estimates?


B.  Guesstimating the Illegal Sports Betting Market

Sports betting advocates fail to distinguish between estimates of illegal wagering activity and the potential casino revenue and tax revenue streams which might be realized if that illegal wagering were instead captured via a regulated sports betting regime. There are actually two separate errors in play here: a) accurately estimating the size of the illicit sports betting market, and b) determining how much of the illicit market could be converted to the regulated market. For the moment, let's focus on estimating the size of the current illegal sports betting market.

Sports betting advocates often tout figures such as the American Gaming Association's estimate that Americans illegally wagered $3.8 billion on this year's Super Bowl (a figure widely adopted by the general media). Or, there's the common assertion that Americans illegally wager up to $400 billion per year on sports. The problem with these estimates is that the figures are presented without any supporting data or underlying assumptions. As my high school math teacher might say, the groups touting these estimates never "show us their work".

Let's take a look at that $400 billion estimate for the amount Americans supposedly wager illegally each year on sports. That figure seems to be a rounding up of an estimate of an annual illegal sports betting market of $80 billion to $380 billion as reported in the 1999 final report of the National Gambling Impact Study Commission (NGISC), generated at the request of Congress. Sure, the data might be a little dated, and the figures are less robust than claimed, but it's still a pretty solid number, right?

Actually, wrong. The NGISC report is pretty easy to find, and sure enough, right there on Page 2-14, the report states: "Estimates of the scope of illegal sports betting in the United States range anywhere from $80 billion to $380 billion annually, making sports betting the most widespread and popular form of gambling in America." The problem arises when you look at the footnotes for that assertion. The NGISC report cites as support for this estimate a Las Vegas Review-Journal newspaper article on a proposed college sports betting ban. Try looking for that article, and the trail grows cold. However, Jordan Weissmann at Slate was enterprising enough to run that footnote to ground. Weissmann discovered that the Las Vegas Review-Journal article in question relied upon estimates given by various individuals to the NGISC during its hearings, with the $380 million figure apparently "pull[ed] out of thin air" by one of the commissioners. Thus was born a supposedly reliable statistic repeatedly cited as authoritative in support of a wide range of important policy decisions. In reality, the $380 billion statistic is, at best, a scientific wild-ass guess ("SWAG").


C.  Conflating Amounts Wagered with Gaming Revenues and Tax Revenues

Another common tactic used by sports betting advocates is to throw out a figure for the amount being wagered on sports betting without clarifying that the amount cited is not the same as the actual revenue being generated for the casino industry, nor is it the amount of tax revenue realized from the casino revenues. Although the gross amount wagered (referred to as the "handle") is usually a huge, attention-grabbing figure, the reality is that the amount retained by the sports book as operating revenue (the "hold") is only a small fraction of the handle. Yet it is the hold that matters most when making policy decisions regarding sports betting.

The David Moulton News-Press op-ed noted earlier makes a particularly egregious hash of this issue. Moulton asserts that the state of Florida will retain 10% of the handle as tax revenues. Moulton's claim is based on the 10% commission (a/k/a "vigorish" or "vig") traditionally imposed by bookmakers on sports wagers. Moulton makes two egregious, fundamental errors here.

First, Moulton fails to recognize what any casual sports bettor knows—sports books refund the commission on all winning wagers and only keep the commission on losing wagers. Sports books want to operate much like a stockbroker and match buyers and sellers (winners and losers), taking a commission along the way for a small but steady piece of the action. Lines on games are set and adjusted to keep the action on both sides as even as possible, minimizing risk to the sports book of being overly exposed to heavy action. Traditional straight bets like point spread and totals (over/under) bets do usually require the bettor to lay 11/10 odds (i.e., bet $11 to win $10, or $110 to win $100), giving the sports book a house edge of roughly 4.76% on the wager (not the 10% edge claimed by Moulton). Other common bets like moneyline wagers will have a similar house edge around 5%, while more exotic wagers like parlays, teasers, futures, and props may have a house edge exceeding 30% (which is why sports books drool when a sucker approaches the counter with a parlay wager).

To get a feel for a reasonable expected hold for traditional sports books, it's easiest to simply see how Nevada sports books have historically performed. Taking the Nevada statewide sports book revenue statistics for the past five years, individual sports bets averaged a hold of 4.9%, parlays averaged a hold of 31.2%, and sports books overall averaged a hold of 5.4%.

Data source: Nevada Gaming Control Board "Gaming Revenue Reports"

UPDATE (28 June 2015):  Via Billy Polcha, Nevada gaming revenue data
for 1984-2014 have been compiled in a user-friendly format 
by the UNLV Center for Gaming Research. 

If one dives into the year-by-year data, the individual sports bets will fluctuate from the expected 4.76% hold depending on sport and how well favorites perform. It is well-known that most sports bettors (so-called "squares") are less sophisticated and will tend to bet on favorites and overs, so sports books often hedge their lines in those directions, padding their edge slightly on those bets. Parlay bets have a house edge of 25%-35%, but the handle on those bets is small relative to individual bets (because of the higher payouts, parlay bettors generally bet smaller amounts). Still, parlay bets consistently add 50 to 60 basis points (0.5% to 0.6%) to the overall house hold each year.

Based on Nevada's actual data, it appears a reasonable assumption that the typical sports betting hold is around 5.5% of the handle. So, just like that, nearly half of Moulton's projected tax revenues evaporate.

But Moulton has made another egregious error—conflating the casino hold (gross gaming revenues) with tax revenues. Assuming the State of Florida is offering sports betting through casinos and racetracks (as is the case in Nevada and is being proposed in New Jersey), the hold from sports wagers represents the gross revenue stream for the casinos and racetracks. The sports books need to pay overhead and expenses, and make a reasonable profit from the hold in order to operate. Actual tax revenues would only be a percentage of the hold.

So, the actual tax revenues depend on what gaming tax rate is applied to the hold, a rate which is likely to vary widely by state. In Nevada, the top marginal tax rate for gross gaming revenues is currently 6.75% (with additional local, county, and state assessments which may add up to an additional 1% to the effective tax rate). In New Jersey, the top marginal tax rate for gross gaming revenues is currently 8.0% (with an additional 1.25% community investment assessment). In Florida, the the top marginal tax rate for slot machine revenues is currently 35% (the state has a compact with the Seminole tribe permitting the tribe exclusive rights to offer certain table games in exchange for a flat annual payment).

It is not clear, however, that Florida would apply its high slot revenue tax rate (35%) to sports book revenues as sports books are more expensive to operate. As one casino industry study noted, there is a direct correlation between lower gaming taxes and higher employment rates in the casino industry. Further, the study notes that many states have adopted lower tax rates for table game revenues in recognition that table games have higher overhead and expenses than do slot machines. The study suggests (p. 29) that 40% of gross revenues is the maximum tax rate for table games to operate profitably. One would suspect that sports books have even greater expenses relative to revenues than table games and cannot operate profitably at such a high tax rate.

So let's do the math. Moulton used an assumption—frankly, a decidedly unscientific wild-ass guesstimate—of $7.5 billion in sports betting handle, and projected tax revenues for the state of Florida of $750 million (10% of the handle). In reality, even if Florida were to have $7.5 billion in handle, the resulting gross revenues would be roughly $412.5 million (assuming a 5.5% hold), with maximum tax revenues of $144.4 million (applying the current 35% tax rate). In other words, even using Moulton's gross gaming handle assumption, and even applying the current 35% tax rate, the actual projected tax revenues for Florida are less than 20% of what Moulton promised. 

It's hard to tell if Moulton is merely cosmically awful at math, too lazy to do basic research about sports betting, or intentionally fudging the numbers with some sleight of hand to create a more palatable illusion of the benefits of sports betting legalization. Whatever the case, Moulton's revenue projections are likely wildly overstated. Still, even $415 million or so in annual gross gaming revenues can create a lot of jobs and economic development. And another $145 million or so in annual tax revenues is nothing to sneeze at, even if it is a rounding error in relation to Florida's $77 billion state budget.

Although not as laughably wrong as Moulton, other sports betting advocates often make similar errors in calculating gaming revenue and tax revenue projections off of gross wagering data. For example, one news story from New Jersey reported that one study projected "sports betting would be a $6.7 billion industry in New Jersey, bringing in $166.2 million in tax revenue." But the numbers don't add up. Assuming $6.7 billion refers to the gross amount wagered (the handle), casino gross revenues would be roughly $368.5 million (assuming 5.5% hold). For the $166.2 million tax revenue projection to hold up, a tax rate of 45% would have to be applied to the gross revenues, rather than New Jersey's current 8% tax rate (which would result in only $29.5 million in tax revenue). Clearly something doesn't add up here.

Or, for another example of overreach by sports betting advocates, New Jersey state senator Ray Lesniak, a vocal advocate for sports betting legalization, has reportedly claimed that sports betting could bring in more than $100 million per year in tax revenue for the state. But simple reverse-calculation shows that $100 million in tax revenue necessarily implies gross casino revenues (hold) of $1.25 billion (assuming 8% tax rate), and gross amounts wagered (handle) of $22.7 billion (or roughly six times Nevada's 2014 sports betting handle) (assuming 5.5% hold). If the $166.2 million tax revenue handle estimate noted above is reverse-calculated, the predicate numbers are $2.1 billion in gross casino revenues (hold) and gross amounts wagered (handle) of $37.8 billion (roughly ten times Nevada's 2014 sports betting handle). These figures may be defensible, but considering New Jersey only has roughly three times the population of Nevada, it is clear these tax revenue projections are incredibly optimistic.

As noted earlier, sports betting financial projections are going to carry a large degree of uncertainty. But if legislators and ultimately voters are to weigh the costs and benefits of sports betting legalization, it would be helpful if the financial projections weren't riddled with obvious and avoidable errors.


D.  Estimating the Potential Size of the Legal Sports Betting Market

In the absence of quality market research (based on scientifically and statistically sound sampling and modeling techniques), is there any way to derive a useful, or at least better informed, estimate of the potential size of the American sports betting market?

Moulton attempts to buttress his estimates of the Florida sports betting market by reference to the amount of sports bets handled by a local bookie. In fairness to Moulton, other sports betting advocates occasionally make the same argument. But the problem with this approach is that there is no way to scale one bookie's business into meaningful statistics for a state or the entire country. The density of bookies in a given community, the number of customers per bookie, the average amount bet by each customer, and other important details will inevitably either vary so widely or be so opaque to verification as to render it impossible to draw any meaningful conclusions beyond the individual bookie's business. As the old saying goes, the plural of "anecdote" is not "data".

1.  Extrapolating from known data (Nevada)

One potential approach to estimating sports betting revenues would be to extrapolate from known data. Unfortunately, with Nevada as the sole data point, extrapolation is likely subject to a high degree of variance. For starters, Nevada is the sole location in the United States offering a full slate of sports betting, and is a mature industry established for several decades. Tourists are a major part of the gaming economy, and are probably much more likely to be inclined to wager on sports than average Americans. Nevada also draws heavily from the wealthy population of neighboring California, skewing direct demographic comparisons to other states. Further, Nevada's major population centers are heavily saturated with casinos, not to mention statewide mobile sports betting, making it more likely legal sports betting has displaced a high percentage of illegal sports betting options (e.g., offshore internet sites and traditional bookies). At best, Nevada can be viewed as a best-case upper boundary on sports gaming revenues in other states (i.e., if a state like New Jersey has roughly three times the population of Nevada, it is unlikely New Jersey will exceed three times the gross sports betting revenues of Nevada, at least in the short-term).

Nevada had gross sports wagers (handle) of $3.9 billion in 2014, and in view of trends over the past five years, can reasonably be projected to exceed $4.0 billion in 2015. Extrapolating to New Jersey, to meet the projections of $100 million in annual tax revenues, if the state had gross sports wagers of $12 billion (three times Nevada, proportionate to population), the state would need to double its gaming tax rate to 16%. Conversely, the state could hold its tax rate at 8% and double the sports wager volume to $24 billion (six times Nevada). The assumption New Jersey will generate six times the gross sports betting handle of Nevada seems somewhat far-fetched, even if New Jersey is the only legal East Coast sports betting venue. [FN1].

One other way to potentially extrapolate meaningful data from Nevada is to look at the ratio of sports betting revenue to overall casino revenue. It's no surprise to anyone familiar with the casino industry that slot machines and table games are the primary gaming revenue drivers. Looking back at the 2014 year-end data for Nevada, the state's casinos had total slot revenues of $6.7 billion, and total table game revenues of $4.2 billion. Sports book revenues, however, were "merely" $227 million. Running the math, sports book revenues represented roughly 2.02% of total gaming revenues (slot, table game, and sports book revenues combined). And again, Nevada is a mature, highly saturated gaming market.

The Nevada sports betting ratio provides us a second useful upper boundary for checking the validity of sports betting revenue estimates. For example, New Jersey gaming revenues were $2.9 billion in 2013, down from a peak of $5.2 billion in 2006. Applying the Nevada ratio to these historical revenue numbers would suggest New Jersey might reasonably expect somewhere between $59.8 million and $107.2 million in annual sports book revenues, which translates into $4.8 million to $8.6 million in additional annual tax revenues (applying the current 8% gaming tax rate). 

On a national basis, the calculation is more complicated because many states have gaming markets which are substantially less mature and less saturated than Nevada and New Jersey. The AGA reports national gaming revenues of $37.34 billion in 2012, nearly equaling the historical revenue high point of $37.52 billion in 2007. Let's assume total gaming revenues increase by roughly 20% by the end of 2015, for total national gaming revenues of roughly $45 billion. Applying the Nevada ratio would suggest we might reasonably expect roughly $930 million in annual national sports book revenues, which translates into annual tax revenues of roughly $139 million (at a 15% tax rate) to $325 million (at a 35% tax rate).

Despite its small population, Nevada accounts for more than one-quarter of national gaming revenues ($10.70 billion of the $37.34 billion in national gaming revenues in 2012). No state has ever outperformed Nevada in gaming revenues in absolute terms, let alone on a population proportional basis. If sports betting advocates want to float sports betting revenue estimates for their state which are greater than Nevada's historical sports betting revenues, it's a fair question to those advocates why they think their state will outperform Nevada in sports betting revenues when they have never done so with respect to other casino gaming revenues.

2.  Extrapolating from demographic data

Acknowledging the limitations of extrapolating from Nevada to other states, is there any way to estimate national figures for sports betting revenues based on something other than a just a wild-ass guess pulled from thin air? One way economists or actuaries might approach the problem would be to estimate gambling habits by demographic group and extrapolate against known populations. Of course, no such rigorous study has been conducted to date. So we are left to attempt what might be best described as a slightly scientific wild-ass guess analysis.

First off, it's important to note that sports betting is an overwhelmingly male-oriented endeavor (one sports book operator in Delaware estimates men are over 90% of his clientele). Next, it's safe to say that there is a significant segment of the male population who either do not gamble at all, or do not gamble on sports. So, let's work with an assumption that roughly 1-in-8 (12.5%) men gamble on sports, along with a small percentage of women. Next, let's assume most men who gamble on sports wager around $5,000 per year on sports (essentially $100-$200 per week during football season, and $1,000 or so during the NCAA basketball tournament), with a smaller group of men being more regular, hardcore sports gamblers who wager greater amounts. We will also reduce the average bet size for the youngest population, commensurate with their lower average earnings. These assumptions (using 2013 Census data) result in gaming revenues and tax revenues as set forth in the following table:

Interactive spreadsheet available via Google Docs; download spreadsheet

into Excel or your own Google sheet to use interactive feature.

Essentially, the use of the above set of assumptions results in total national sports wagers (handle) of $215 billion, with gross casino revenues (hold) of $11.8 billion, and tax revenues of $1.7 billion to $3.5 million (assuming a tax rate of 15% to 30% of gross gaming revenues). Note that these assumptions result in an estimate that there are roughly 16 million potential sports bettors nationally, each wagering (not losing—just placing total bets) roughly $13,500 per year on average (the Totals row contains the weighted average for wagers placed given the initial assumptions used). If the estimates of total sports bettors or average wager seem high or low, one must question the validity of the underlying assumptions. Frankly, considering this estimate is an order of magnitude (roughly 12 times) larger than the national projections based on the Nevada ratio, this estimate most likely overstates the potential gaming revenues to a significant degree. Certainly the oft-cited $380 billion illegal sports betting market statistic looks increasingly dubious even under this more optimistic analysis.

Of course, the above set of assumptions were conjured out of the ether, with only the flimsiest of tethers to reality. If one downloads and plays with the spreadsheet, it quickly becomes obvious that the bottom line handle, hold, and tax figures are highly sensitive to the initial assumptions used. But without more rigorous data from scientifically validated surveys, these kinds of guesstimates are about as good as we can get, which means every estimate of gaming revenues and tax revenues from sports betting legalization has to be accompanied by large asterisk noting a significant margin of error.


E.  Market Issues:  Expansion, Conversion, and Competition

As if the difficulty of estimating the potential sports betting market size weren't already difficult enough, there are a number of issues which further complicate the process.

First, there is the issue of market expansion. There is likely a decent group of potential sports bettors who are currently not betting because they lack a connection to an illegal gambling option or choose not to use such a gambling option. Legalization of sports gambling would give these individuals an outlet to pursue sports gambling, expanding the sports betting market.

Next, there is the issue of market conversion. There is unquestionably a thriving illicit sports gambling market being utilized by sports gamblers in those states without a legal sports gambling option (essentially everywhere except Nevada, for sports gamblers who either live in or can easily travel to Nevada). The interesting question is how much of the illicit market will migrate to the legal market once sports betting is legalized in additional states. Although the legal market would superficially seem to offer significant advantages for sports gamblers, that assumption is not without major caveats.

Sports gamblers in recent years have become accustomed to immediate, around-the-clock, online access to sports betting. Some of this action is via direct wagering on offshore internet sports gambling sites, while much of the illicit action is mediated by local bookies who use offshore sites as a method for booking wagers. For example, a sports bettor might approach a bookie about betting on games. The bookie sets up an offshore account with a small deposit. The bookie makes the account available to the bettor, and they agree to a proportional betting scheme; e.g., $1 bet on the site equals $10 bet in real life. The bettor then makes small wagers online, which translate into larger real life bets with the bookie. Periodically, the bettor and bookie meet up to "square up" the account in real dollars.

Additionally, highly aggressive tax rates on sports book revenues are likely to be passed through to consumers in the form of higher commissions or surcharges. Further, legalized sports books will be forced to do tax reporting on larger bets and payouts. Sophisticated and higher volume sports bettors might well find that legalized sports betting is impossible to beat once higher taxes and commissions are taken into account, and will instead make the rational economic decision to continue utilizing illicit gaming channels.

Given the realities of modern, online sports betting, there is a significant question as to how much illicit sports betting will migrate to legal options post-legalization. In a highly saturated gaming market like Nevada where both the brick-and-mortar casinos and mobile sports book options make sports betting convenient and ubiquitous, the conversion rate from illicit to legal sports betting will be a fairly high percentage. But in states where legal sports books are limited geographically and there is no online or mobile betting option, the conversion rate might be significantly lower. Certainly there is no basis to assume that all or even most currently illicit sports betting will necessarily move to legal options post-legalization.

Finally, there is the issue of market competition. Spurred in part by a UIGEA carveout, online fantasy sports competitions have boomed in the past decade. The relatively recent innovation of "daily fantasy sports" (DFS) contests on sites such as FanDuel and DraftKings has driven explosive financial growth in the fantasy sports market, with industry experts projecting revenues exceeding $2.5 billion by 2020. As Chris Grove of Online Daily Fantasy Report notes, the potential impact of DFS-style gaming on traditional casino gaming could be significant:

Social [gaming] and DFS don’t have to make a dollar to cost casinos a dollar of revenue.

Instead, they can (in theory) offer consumers an experience similar to gambling but at a lower cost. So the increasing popularity of DFS, for example, could have an outsized negative impact on casino revenues, one that isn’t properly communicated by the pure revenue number of the DFS industry.

It doesn't take a rocket scientist to project that DFS-style gaming is potentially a bigger threat to traditional sports betting than it is to, say, slots or blackjack. Currently, DFS holds two significant advantages over traditional brick and mortar sports betting—DFS is legal and DFS is mobile. People who are interested in sports betting (particularly younger people) may find that DFS satisfies their sports betting needs, and may well find the DFS experience superior to traditional sports betting.

Of course, it would be absurd to think DFS will single-handedly destroy traditional sports betting in the short-term. The markets for DFS and traditional sports betting may not overlap to a significant degree. DFS might actually expand the traditional sports betting market by creating new sports bettors. Brick and mortar casinos could also offer DFS wagering, as is currently permitted in New Jersey casinos. But fifty years ago, who would have anticipated the decline of the horse and dog racing industries, once the centerpiece of legalized gambling in most states, now mostly kept afloat via subsidies from other casino revenue streams? It would be folly not to at least consider the possible effects of DFS on traditional sports betting revenues.

The issue of market competition also applies in state-by-state analyses of the sports betting market. As an example, the New Jersey casino market has been decimated in recent years by expanded gaming competition in nearby markets. Even if New Jersey were to legalize sports betting, there is no guarantee neighboring states would not escalate the gaming wars and likewise legalize sports betting, siphoning off a huge chunk of New Jersey's anticipated sports betting revenues. Consequently, any state-specific sports betting revenue projections must be accompanied by significant caveats and qualifications regarding anticipated competition from nearby markets.


F.  Conclusion

So, after all of this jibber-jabber, how much casino and tax revenue can we reasonably expect to be generated by widespread legalization and taxation of sports betting?

Your guess is as good as mine.*

-----------------------------------------------------------------------------------------

[FN1] Applied to Florida which has seven times the population of Nevada (and its own healthy tourism industry), the upper boundary for sports betting gross wagers (handle) is $28 billion, with gross gaming revenues (hold) of $1.54 billion, and annual tax revenues of $539 million (assuming a 35% tax rate). In other words, still well short of David Moulton's estimated $750 million in annual tax revenues.
