Michigan online sports betting revenue dives in August
Online sports betting revenues plunged in August in Michigan, as books held at 10.5%. The gross was US$35.5 million on handle of US$338 million. Revenues fell 30% despite handle being only 2% lower.
iGaming revenue in the state, however, was up 1%, reaching US$303 million. That was a sequential slowdown from July’s 21% spike, which J.P. Morgan analyst Daniel Politzer attributed to one less weekend day in August and no Labor Day weekend.
The tightest hold in Michigan was BetMGM’s 14%. The book grossed US$4.8 million.
The highest gross was FanDuel’s US$12 million, as it held at a state-average 10.5%. Close behind in hold was DraftKings at 10.4%. It made US$9.5 million.
Holding at 9.2%, BetRivers grossed US$600,000. Caesars Sportsbook took in US$700,000 on a hold percentage of 4.3%, loosest in the state.
theScore Bet won US$1.2 million and Bet365 captured US$1.8 million. Fanatics Sportsbook took in US$3.3 million, the state’s fourth-highest gross. Hold percentages were not available for those books. All online providers except newcomers theScore and Bet365 suffered double-digit revenue declines, the steepest being Caesars’ 42%.
Among i-gaming providers, FanDuel led with US$72.7 million, off 1% from August 2025. BetMGM was next with US$64.1 million, down 4%.
DraftKings’ online-casino revenue was US$53.6 million, up 2%. BetRivers climbed 13% to US$22.5 million. Caesars Digital made US$20.3 million, a 12% jump.
Hollywood Casino’s US$8 million represented a 10% increase. All other i-casinos combined for US$14.9 million, a 21% aggregate surge.

The Backstory
Michigan’s August drop fits a wider hold-driven pattern
Michigan’s August online sports betting results underline a recurring feature of the U.S. market: revenue can swing sharply even when wagering volume changes little. The state’s US$35.5 million in online sports betting revenue came from US$338 million in handle, with books holding 10.5%. Handle was only 2% lower, but revenue fell 30%, showing how month-to-month win rates can overwhelm underlying betting activity.
That dynamic has appeared in other states this year. In Maryland, for example, June handle rose 30.1% year over year to US$515 million, helped by soccer betting tied to the World Cup, but revenue fell 3.2% to US$54.4 million as hold landed at 10.5%. The result showed that higher volumes do not automatically translate into higher win if pricing, customer outcomes or betting mix move against operators. The same state had produced stronger figures earlier in the spring, making June a useful comparison point for Michigan’s August reversal.
Michigan’s 10.5% hold was not weak by national standards. But after a stronger prior month, the sequential fall in sports betting revenue points to the sensitivity of operator results to calendar effects, sport mix and customer-friendly outcomes. J.P. Morgan analyst Daniel Politzer noted that Michigan’s iGaming growth also slowed from July, citing one fewer weekend day in August and the absence of a Labor Day weekend. Those same calendar factors can weigh on wagering engagement, particularly in a late-summer period before football reaches full scale.
FanDuel and DraftKings remain the benchmark
The Michigan data again put FanDuel and DraftKings at the center of the online sports betting market. FanDuel generated the highest gross in Michigan at US$12 million while holding at the state average of 10.5%. DraftKings followed with US$9.5 million and a 10.4% hold. Together, they remained the primary revenue engines, even as most operators posted double-digit declines.
That hierarchy has been consistent across several comparable states. In Maryland’s March online sports betting surge, FanDuel led with US$28.4 million in revenue on US$233.6 million in handle, supported by a 12.1% hold. DraftKings was second with US$17.3 million on US$183.9 million. A month later, Maryland online sports betting revenue rose 5.6% in April, and the same two operators dominated again: FanDuel won US$29 million and DraftKings won US$16.9 million.
Missouri’s early market performance has shown a similar split at the top, though with tighter competition between the two brands. In Missouri’s May sportsbook results, DraftKings narrowly beat FanDuel in revenue, US$11.8 million to US$11.7 million, despite FanDuel posting the stronger hold at 14.1%. The comparison matters for Michigan because it shows how leadership can vary by month, but scale, brand reach and pricing efficiency continue to favor the same national operators.
Second-tier operators are fighting for share and consistency
Behind the leaders, Michigan’s August figures illustrated the uneven performance of the second tier. BetMGM held the tightest in the state at 14% and grossed US$4.8 million. Fanatics Sportsbook posted US$3.3 million, the fourth-highest gross. Bet365 took US$1.8 million, while theScore Bet won US$1.2 million. Caesars Sportsbook generated US$700,000 on a 4.3% hold, the loosest in the state, and suffered one of the sharpest revenue drops.
The relative positions of these brands have been changing across markets. Fanatics has been steadily pressing into third-place contention in Maryland, where it edged BetMGM in April revenue, US$4.5 million to US$4.2 million, after also placing third in March. But in Maryland’s June sports betting results, BetMGM retook the third spot with US$3.8 million in winnings, while Fanatics brought in US$3.4 million. The swings suggest that neither operator has locked in a durable No. 3 position nationally.
Missouri has offered another view of that competition. In February, Fanatics Sportsbook generated US$1.6 million in revenue, ahead of BetMGM’s US$1.4 million, while Bet365 held a stronger third-place position at US$2.2 million. By May, Bet365 again took third in Missouri with US$2.2 million, while Fanatics reached US$2 million and BetMGM trailed at US$1.1 million. Michigan’s August results align with that pattern: BetMGM can outperform on hold in some months, but Fanatics and Bet365 are increasingly important to the competitive field.
Promotions and market maturity are reshaping results
Michigan is a mature online gambling market, so its August figures were less about launch volatility than about operating leverage in a settled environment. But developments in Missouri show how promotions can distort early results and complicate comparisons across states. In Missouri’s February sports betting market, promotional allowances fell to US$11 million, equal to 36% of revenue, down from 61% in January. Politzer described the movement as typical noise tied to promotions and state accounting in the first months after launch.
By May, Missouri promotional outlays had declined to US$7 million, signaling a move toward normalization. That matters because promotional deductions and free-bet strategies can obscure the true profitability of headline revenue. States that permit generous deductions can report gross revenue figures that do not fully reflect tax receipts or operator economics. Michigan’s August decline, by contrast, appears more directly tied to lower win and calendar factors than to a launch-market promotional reset.
Still, the same strategic questions apply. Operators have to decide how much to spend to defend share when sports calendars soften. FanDuel, DraftKings, BetMGM, Fanatics and Bet365 are all balancing customer acquisition against margin discipline. In mature states, aggressive promotion can protect handle but may not prevent revenue declines if hold weakens. In newer markets, promotions can accelerate early share gains but delay clean readings on market strength.
iGaming softens the blow in Michigan
Michigan’s broader online gambling profile differs from sports-only markets because iGaming provides a larger, steadier revenue base. While online sports betting revenue fell sharply in August, iGaming revenue rose 1% to US$303 million. That total dwarfed the sportsbook figure and helped cushion the state’s overall digital gambling performance.
The iGaming rankings also showed a familiar concentration among national leaders. FanDuel led with US$72.7 million, followed by BetMGM at US$64.1 million and DraftKings at US$53.6 million. BetRivers rose 13% to US$22.5 million, Caesars Digital increased 12% to US$20.3 million and Hollywood Casino was up 10% to US$8 million. Smaller iCasinos collectively grew 21%, suggesting that the online casino market has more room for share shifts than the sports betting market, where FanDuel and DraftKings often dominate.
The contrast between Michigan’s sports betting and iGaming results highlights why states with legal online casino can be more attractive to operators. Sportsbook revenue is seasonal and exposed to hold volatility. Online casino play is more continuous, with less dependence on the sports calendar. For companies active in both verticals, Michigan’s August figures show how iGaming can stabilize revenue even when sports betting win falls.
The stakes move beyond one soft month
Michigan’s August decline does not necessarily point to structural weakness. A 10.5% hold remains healthy, football betting had not yet fully arrived and iGaming continued to grow. But the report reinforces how investors and regulators should read monthly sports betting data: handle, hold and promotional activity must be assessed together.
The related results from Maryland and Missouri show the same lesson from different angles. Maryland demonstrated that surging handle can coincide with lower revenue when hold eases. Missouri showed that promotions can cloud early-market performance before spending normalizes. Michigan now adds a mature-market example in which a modest handle decline and calendar effects helped produce a much steeper revenue drop.
For operators, the stakes are competitive and financial. FanDuel and DraftKings continue to set the pace. BetMGM, Fanatics, Bet365, Caesars, BetRivers and theScore Bet are competing for profitable scale in a market where small differences in hold can translate into large revenue gaps. For Michigan, the key question is whether the arrival of the fall sports calendar restores sportsbook momentum while iGaming continues to expand.
