US Sports Betting Revenue Declines Sharply in August

U.S. commercial sports betting revenue fell 15.6% year-over-year to $1.00 billion in August, according to the American Gaming Association’s latest Commercial Gaming Revenue Tracker. The trade group attributed the decline in part to competition from prediction market platforms and a later start to the college football season. The drop was significant enough to pull total commercial gaming revenue down 0.6% for the month, even as traditional casino gaming continued to grow.

Sports Betting Contracted on Multiple Fronts

The August figures reflect weakness in both customer activity and operator performance. Total sports betting handle declined 0.7% to $10.89 billion, indicating that wagering volume was largely flat compared with the prior year. The sharper fall in revenue suggests that sportsbooks also retained a smaller share of the amounts wagered than they did in August 2025.

The AGA identified two primary factors behind the downturn. The first is the growing presence of prediction market platforms, which offer sports-related event contracts outside the traditional state-licensed sportsbook framework. The second is a calendar effect: the college football season began later than in the previous year, reducing the volume of early-season wagering that typically supports August results.

The monthly decline is consistent with broader pressure on the sector. Sports betting revenue had already posted its second monthly decline of the year earlier in 2026, with both handle and hold contracting during that period.

Land-based casino operations continued their steady expansion. Traditional casino gaming revenue – slots and table games combined – rose 0.9% year-over-year to $4.44 billion in August. Slot machines generated $3.25 billion, an increase of approximately 1%, while table games produced $885.91 million.

Online casino gaming remained the fastest-growing commercial segment. iGaming revenue continued to post year-over-year gains through the month, offsetting a portion of the sports betting shortfall and underscoring the ongoing shift of gaming activity toward digital channels.

Prediction Markets Remain a Central Industry Concern

The August results arrive amid an intensifying debate over prediction markets’ role in the U.S. gaming landscape. The AGA has increasingly framed these platforms as a competitive and regulatory concern. In May, the trade group estimated that states have missed out on approximately $1 billion in tax revenue since the start of 2025 due to prediction market activity occurring outside state licensing and taxation systems.

The AGA has also taken a more public stance, deploying advertising campaigns in select U.S. markets that criticize the proliferation of prediction market platforms. On the regulatory front, the legal environment remains unsettled. A federal appeals court ruling in 2026 supported Nevada’s ability to shut down sports-related prediction markets, while officials in other states, including Arizona, have examined whether such platforms are operating in violation of state gambling laws.

Industry participants remain divided on the issue. Supporters of prediction markets argue that they represent a distinct, federally regulated product category under the Commodity Exchange Act, while licensed operators and state regulators contend that sports event contracts function as unregulated wagers that circumvent consumer protections and state tax structures.
