U.S. Sports Betting Data: Market Share Stats By Brand, Gross Gaming Revenue, Parlay Handle, Hold

If you’re seeking data and statistics to tell the story of the regulated U.S. sports betting market, you have come to the right place and right page.

Our team of journalists and analysts has been studying the regulated market since its inception. With this live database here, built upon state agency filings, we will identify which operators are generating what revenues, state taxes generated in each jurisdiction, how parlay wagering has come to dominate the market, and more.

The charts and statistics below are presented by Casino Reports in collaboration with independent analyst Alfonso Straffon, a longtime industry observer, former sports trader, and equities analyst at Deutsche Bank. The charts will be updated on a monthly basis, on or about the third Thursday, to reflect the latest state filing data.

1. Sports betting handle market share (January 2021 to present)

Key Insights:

• FanDuel Sportsbook reclaimed the handle crown from DraftKings Sportsbook in 2024, but DraftKings reclaimed it back early in 2025. FanDuel is back on top by less than a percentage point (36.1% to 35.5%), according to the latest figures.
• Check out the positive inflection in the “Others” category around the start of 2024. That is a reflection of (1) the entry of bet365 into six additional states (giving it 11 total) within the past year, and (2) gains by Fanatics since taking over PointsBet. 
• Dating to at least January 2021, the duopoly of FanDuel Sportsbook and DraftKings Sportsbook has hovered between approximately 30 and 40% each for market share of the nationwide regulated sports betting handle — i.e., dollars wagered/risked by bettors (irrespective of wins and losses).
• That combined market share currently totals 71.5% of the dollars wagered in the regulated U.S. market, down slightly from historical highs of around 75%.
• BetMGM, Caesars, and ESPN Bet comprise the second tier. They have oscillated between about 2% and 11% apiece for the national market share.

Notes: The yellow spike in January 2022 for Caesars reflects an auspicious advertisement-and bonus-fueled start in New York state, coinciding with the NFL playoffs. Unfortunately for Caesars, the momentum did not last. However, Caesars’ share has held steady in the 6-7% range for both sports betting and the more lucrative iCasino sector.

2. Sports betting market share by gross gaming revenue (GGR) (January 2021 to present)

Key Insights:

• A chalky March Madness (aka “customer-friendly” results) produced some turbulence in this charting in the first third of 2025 when FanDuel had a 10-point lead in market share of sports betting GGR. DraftKings took a narrow lead through March, then FanDuel regained the top spot at 40.5% through the latest figures (April 2025).
• In general, FanDuel is believed to have a higher mixture of parlay bets and correspondingly greater hold percentage, although that also makes it subject to some volatility when the chalk (favorites) align.
• FanDuel’s parent company Flutter believes that it possesses superior abilities and systems for pricing and risk-management and an overall more effective parlay engine. 

Notes: We will continue to monitor ESPN Bet, which is battling in a make-or-break stretch for its PENN Interactive-controlled brand. Likewise, Hard Rock Bet, a well-financed Seminole Tribe-backed product, will leverage its monopoly position in Florida for gains across the country. Figures from Florida do not get reported and therefore are unknown publicly.

3. Sports betting handle by state, last twelve months (LTM) (2025)

Key Insights:

• That’s a whopping $24.21 billion wagered at New York over the last 12 months. New York’s nine regulated sportsbooks have handled more on average per month (about $2 billion) than more than a dozen of the other states’ totals LTM.
• That’s not terribly surprising given the population of New York and its relatively high per capita income, buoyed by zip codes around New York City, Long Island, and Westchester County. 
• Oregon and New Hampshire, where DraftKings owns a sportsbook monopoly, did challenge for $1 billion handle for 2024 but both fell a bit short at $900 million and $800 million, respectively.

Notes: Mississippi regulators and lawmakers have repeatedly flirted with authorizing online sports betting — most recently in March — but for now it remains a state with on-premises betting at casinos only.

If or when Texas and California join the ranks of the regulated U.S. sports betting states — something that Las Vegas Sands is determined to make happen, at least in Texas, based on spending — it will be interesting to see how the top of the chart shakes out.

4. Sports betting gross revenue by state, LTM through (2025)

Key Insights:

• Operators are generating large sums in New York but also had to pay a $25 million up-front licensing fee for the privilege of doing business in the state. New York also levies a nation-leading 51% tax on the GGR generated by its authorized sportsbooks (tied with Rhode Island and Vermont for the highest).
• Do not conflate gross revenue with net revenue!
• North Carolina is a regulated sports betting newcomer, having launched its online market in January 2024 to industry and consumer fanfare. It’s early but, after one year, the state’s GGR has climbed past Michigan and into the top 10.
• Illinois had been one of the more lucrative states for operators. In June 2024, however, Gov. JB Pritzker signed into law a state budget that instituted a new progressive tax scheme effective July 1, 2024.

Notes: The law raises the privilege tax on a licensee’s annual adjusted gross sports wagering receipts (AGSWR) to the following rates:

• 20% of annual AGSWR up to and including $30 million;
• 25% of annual AGSWR in excess of $30 million but not to exceed $50 million;
• 30% of annual AGSWR in excess of $50 million but not to exceed $100 million;
• 35% of annual AGSWR in excess of $100 million but not to exceed $200 million;
• 40% of annual AGSWR in excess of $200 million.

The 40% tax will be felt only by DraftKings and FanDuel, which was the intent of the tax structure modification. The other market participants, barring a surge in revenue, will not reach the thresholds subjecting them to the higher rates.

The taxation situation has become even more precarious and onerous in top the two operators in Illinois. In June 2025, the legislature passed a budget bill that contained an additional per-wager tax — 25 cents for an operator’s first 20 million wagers, 50 cents for wagers above that.

On June 10, FanDuel announced in response that it would impose a 50-cent transaction fee on all wagers placed in Illinois, effective Sept. 1. The company said that if Illinois lawmakers were to eliminate the new tax, it would do the same with its own new line item. We shall see what impact these unique policy changes have on the handle and GGR figures.

5. Sports betting taxes generated by state, LTM through (2025)

Key Insights:

• The tax structure modifications in Illinois has resulted in the state jumping into second place in recent months. Over the last 12 months, it checks in at $361.21 million.
• New York has collected by far the most tax revenue from sports betting with its 51% tax rate on GGR, good for $1.21 billion for 12 months spanning February 2024 through January 2025.
• Effective June 2023, Ohio raised its tax rate on operator GGR from 10% as established at the time of legalization to 20% — and may increase it again. Consider that Ohio’s haul would be roughly halved and would slide in alongside Maryland if not for the adjustment.
• Pennsylvania also sits on the higher end of the scale with its 36% rate on operator GGR, which was established at the time of sports betting legalization in the state. The state has generated $162.39 million over the LTM, fourth only to New York, Illinois, and Ohio. The results of the Super Bowl, in which the Philadelphia Eagles annihilated the Kansas City Chiefs, was not a fiscally favorable results for the house.

Notes: Illinois’ shift from 15% to a progressive structure and further per-bet increase may have ripple effects in other states, with lawmakers potentially developing an appetite to turn up the dial on operators. Meantime, tax increases on the base rates have been realized in other states:

• New Jersey Gov. Phil Murphy has proposed increasing the sports betting tax rate from 13% to 25% (and iGaming tax rate from 15% to 25%) in his 2025 budget.
• Maryland’s rate increased from 15% to 20% via Gov. Wes Moore’s Budget Reconciliation and Financing Act of 202, less than the doubling Moore had sought.
• Louisiana‘s Senate in June approved a tax increase on digital sports betting revenue from 15% to 21.5%. That change is over to Gov. Jeff Landry for signature.
• North Carolina might grow from 18% to 36% if the House budget reflects the Senate’s desire to double up on operators.
• Multiple additional jurisdictions, including Indiana and Ohio, are considering similar proposals.

The 2024 Illinois increase triggered a response from the operator side. DraftKings, coinciding with its third-quarter earnings report, floated a plan in August last year to pass the elevated Illinois tax back to the bettor as a surcharge on winning bets. To say the idea was roundly rejected and panned would be putting it mildly. But it took until FanDuel (Flutter) during its own earnings call two weeks later said it absolutely would not follow DraftKings’ lead and for DK to publicly abandon the idea and try to save face. Still, DraftKings CEO Jason Robins has said the company will consider any and all ideas to protect its margins. Back to the drawing board in Illinois.

6. Parlay hold % versus non-parlay hold (January 2021 to present)

Key Insights:

• There’s a good amount of volatility from month to month, but the overall, long-term trend for hold percentage at U.S. regulated sportsbooks is upward. This is due to a variety of factors, including customer adoption and familiarity with Same Game Parlay (SGP) wagers, improvements in operator pricing, and operator emphasis on serving up these higher-margin offerings in its favor.
• This chart contemplates the betting activity in New Jersey, Colorado, Illinois, and Maryland only, though it’s a pretty nice sample considering the overall volume in these states. The data reporting into granular bet kinds like parlays is more robust and transparent in some states than in others.
• The highest parlay hold percentage we have observed is approximately 26% in November 2021, which then sharply turned in the other direction in the ensuing months.
• For the most part, the hold percentage on parlay bets and non-parlay bets is correlated — i.e., when one goes up or down, usually the other does, too.

7. Parlay betting revenue’s percentage of overall betting revenue (January 2021 to present)

Key Insights

• The bettors had their way thanks to a favorites-heavy NCAA men’s basketball tournament in March 2025, collectively knocking the parlay revenue to below half of operator revenue (47%), which had only happened in three other months since the start of 2023. It has jumped back to nearly 60%.
• Prior to that, the percentage of revenue derived from parlay bets spiked to 69% in September 2024 as the trendline remains angled upwards.
• While the sample is indeed a subset of the regulated market nationally, the four states supplying this data are qualitatively a broad and diverse sample.
• How high can the figures go here? We shall see as it’s probably limited only by ingenuity. For example, how can parlays get folded into live betting? Already some sportsbooks do offer the ability to make in-game SGPs.

8. Parlay betting as a percentage of overall handle (January 2021 to present)

Key Insights:

• Dating back almost four years, this number has grown from around 20% of overall handle to 33% for December 2024. It has receded slightly in recent months.
• The ceiling here isn’t limitless, as long as there are VIPs in the regulated market making large straight wagers on football and basketball.

9. National sports betting hold percentage on quarterly basis (January 2021 to present)

Key insights:

• Analysts deal in quarters, not months, so this chart is for them.
• In October and December 2024, the Q4 figure dropped to 7.9% on the back of “customer-friendly” NFL results — i.e., lots of favorites covering. Booking sports can be a volatile business, even in the era of parlays.
• 1Q25 saw a continuation of the trend, causing some revisions downward on revenue projections across the industry.
• The quarterly handle has reached or exceeded 10% three times: 3Q22 at 10.6%, 2Q24 at 10%, and 3Q24 at 10.5%.
• If you’re going to bet on which way this number is going, it probably would be wise to play the over on 10% for future quarters.
• Historically, pre-PASPA when Nevada was the main vein for regulated betting in the U.S. and parlays were given far less emphasis, this number lived closer to 5% than 10%.
