US Commercial Gaming Revenue Slips 0.6% in August as Lower Hold Cuts Sports Betting 15.6%

American commercial gaming took $6.48 billion in August, a fraction less than a year earlier, because sportsbooks kept less of what was bet. Handle barely moved; hold fell from 10.8% to 9.2%, and the American Gaming Association blames prediction markets and a late college football start for the rest.

• US commercial gaming revenue was $6.48 billion in August 2026, down 0.6% on August 2025, according to the American Gaming Association's Commercial Gaming Revenue Tracker published on 21 October
• Sports betting revenue fell 15.6% to $1.00 billion on handle of $10.89 billion, down 0.7%, as hold dropped to 9.2% from 10.8%; iGaming rose 12.3% to $1.03 billion and land-based casino gaming 0.9% to $4.44 billion
• The AGA says August handle was hit by sports betting on prediction markets and a later start to the college football season, and that, June and July's World Cup aside, handle has been down year on year since December 2025
• Year to date, revenue is $53.84 billion, up 5.4%, with sports betting up 4.0% and iGaming up 17.4%; Oklahoma had not reported July or August
• The AGA now puts the gaming tax lost to prediction markets since the start of 2025 at over an estimated $1.56 billion, up from the more than $1.3 billion it cited in its NFL projection in September

Sports Betting Drags a Flat Month Into Decline

US commercial gaming generated $6.48 billion of gross gaming revenue in August 2026, 0.6% less than in August 2025, according to the American Gaming Association's (AGA) monthly Commercial Gaming Revenue Tracker, released on 21 October. The association's summary says growth in brick-and-mortar gaming and iGaming was "more than offset by significantly lower sports betting revenue".

Traditional casino gaming rose 0.9% to $4.44 billion. Slot machines generated $3.25 billion, up 1.0%, and table games $885.91 million, up 2.1%. The AGA says slot revenue was uneven across states and credits table growth in part to the expansion of Resorts World New York City, which moved from the state's video lottery reports into its casino reports in April.

Sports betting revenue fell 15.6% to $1.00 billion on handle of $10.89 billion, down 0.7%. The AGA gives two reasons for the softer handle: the availability of sports betting on "so-called 'prediction markets'", in its words, and a later start to the college football season. It adds that, outside June and July, which benefited from the World Cup, handle has been down year on year since December 2025. Revenue was also hurt, the association says, by hold falling to 9.2% from 10.8% last August.

iGaming generated $1.03 billion, up 12.3%, slightly more than sports betting in the month. With no new markets coming online, the AGA says, iGaming growth "continues to steadily moderate"; the association's monthly chart shows the year-on-year rate above 30% in most of the first half of 2025.

Eight Months Up, Tax Down

For January to August, commercial gaming revenue was $53.84 billion, up 5.4% on the same period of 2025. Traditional gaming contributed $35.25 billion, up 3.4%; sports betting $10.45 billion, up 4.0%; and iGaming $8.11 billion, up 17.4%. The AGA notes that Oklahoma had not reported July and August data at the time of the report. Its August summary does not list which states rose or fell.

State reports already published fill in part of the picture. New Jersey's total gaming revenue fell 4.1% to $615.7 million, with sports wagering revenue down 25.0%, which its Division of Gaming Enforcement put down to the later fall sports calendar and a lower win percentage. Louisiana's casinos won $201.0 million, down 6.4%, with every district but Baton Rouge lower.

Gaming taxes for state programmes came to $1.46 billion in August, down 1.5%, and state sports betting tax revenue fell 14.0%. The AGA says the total could have been "significantly higher" but for skill machines, sweepstakes casinos and "illegal sports betting through 'prediction market' platforms", none of which pay state gaming taxes. It estimates prediction markets offering "backdoor sports bets" have cost states over an estimated $1.56 billion in potential gaming taxes since the start of 2025. The tracker does not set out how that figure is calculated.

September Looks Different on Handle

Early September data points the other way on volume. Stifel estimated US sports betting handle rose about 4% year on year in September across 13 reporting states, despite one fewer week of NFL games, while revenue fell 9% as results largely favoured bettors, according to Legal Sports Report's account of the broker's note on 20 October. Stifel put taker-only volume on CFTC-regulated prediction markets at $17.7 billion, growth of 27% on its measure against a 43% month-on-month rise in regulated handle, and said the gap could signal earlier-than-expected saturation. The note itself is not public.

Hold, Not Handle, Explains Almost All of August's Fall

On our arithmetic from the AGA's figures, August 2025 sports betting revenue was about $1.18 billion. Had hold stayed at 10.8%, this August's $10.89 billion of handle would have produced roughly $1.18 billion again; at 9.2% it produced $1.00 billion. The fall in hold therefore accounts for nearly all of the 15.6% decline, and the 0.7% dip in handle for very little. That matters because hold over a single month is largely driven by results, while handle measures demand. The AGA's prediction-market attribution is about handle, and in August that is a claim about a flat line rather than a falling one. On the association's own chart, handle growth since December 2025 has hovered close to zero rather than declined steadily, which is consistent with stalled demand but not yet with a market in reverse.

The Prediction-Market Case Rests on What Did Not Grow

The cannibalisation argument is about counterfactuals. Legal handle grew by double digits through most of 2025, and the AGA says its growth stalled once prediction-market sports contracts launched widely. Its forecast of a flat NFL season makes the same point; Eilers & Krejcik's estimate that exchanges will take about 21% of NFL wagering this season gives it scale. Stifel's September numbers complicate it: sportsbook handle growth outran its taker measure of exchange volume. Both can be true at once if the exchanges took the growth and then slowed. The tax figure is the AGA's policy argument rather than a measured loss, since it depends on assuming those trades would otherwise have been taxable sportsbook bets.

August was a hold story dressed as a demand story. The AGA's September tracker, with every state reported, will show whether its prediction-market warning is about the level of betting or only about its growth.
