U.S. Sports Betting Revenue Contracts for Second Straight Month in May 2026
The American Gaming Association released its latest Commercial Gaming Revenue Tracker data showing U.S. sports betting revenue fell 1.8 percent year-over-year to 1.34 billion dollars in May 2026 while the handle slipped 0.4 percent to 12.06 billion dollars, and this marks the second consecutive month of contraction for the category even as other segments of the commercial gaming market continued to expand.
Figures compiled by the association indicate that state-regulated sports betting operators collected less revenue than they did during the same period in 2025, and the decline occurred alongside steady growth in traditional casino gaming along with iGaming products across multiple jurisdictions.
Key Figures from the May 2026 Report
Revenue reached 1.34 billion dollars after operators paid out winnings on a total handle of 12.06 billion dollars, which represents a modest pullback from the prior year when both metrics posted higher totals according to the same data source. The association's tracker further shows that state tax collections tied directly to sports betting activity also declined during the month, while overall commercial gaming revenue across all categories still posted net gains because casino and iGaming segments offset the sports betting shortfall.
Observers tracking these numbers note that the contraction follows an April 2026 dip as well, creating a two-month trend that stands in contrast to the longer-term expansion the market experienced after widespread legalization began in 2018. Data from the tracker links these results to a specific shift in where sports-related wagering volume now flows, particularly into platforms operating outside full state regulatory oversight.
Competition from Prediction Market Platforms
The report attributes part of the volume movement to expanding activity on unregulated or backdoor prediction market platforms, with Kalshi cited as one example capturing significant sports-related bets that fall beyond traditional state licensing structures. These platforms allow users to trade contracts tied to event outcomes, and they operate under frameworks that differ from the licensing requirements applied to retail and online sportsbooks in most states, which means the wagers do not contribute to the same tax or reporting streams tracked by the American Gaming Association.
Industry analysts reviewing the May numbers point out that this diversion of handle reduces the taxable base for states that rely on sports betting excise taxes, and the effect appears most noticeable in markets where prediction contracts overlap directly with popular sports propositions. The tracker data does not quantify the exact share of volume moving to these platforms, yet the association explicitly connects the revenue decline to their growing presence during the spring of 2026.
Performance Across Other Gaming Segments
While sports betting revenue contracted, the same Commercial Gaming Revenue Tracker shows traditional casino gaming and iGaming categories posted year-over-year gains in May 2026, and these increases helped maintain overall industry growth even as sports betting pulled back. Casino floor revenue benefited from steady visitor traffic and higher table game hold percentages in several major markets, whereas iGaming operators reported continued expansion in states that permit online casino games alongside sports betting.
State tax revenue derived from sports betting specifically declined in line with the operator revenue drop, yet taxes collected from casino and iGaming activity rose enough to produce a net positive for many state budgets according to the association's aggregated figures. This divergence highlights how different segments respond to distinct competitive pressures and regulatory environments during the same reporting period.
Context Entering July 2026
As the industry moves into July 2026, the two-month contraction in sports betting revenue stands as the clearest signal yet that competition from outside the regulated framework is influencing results in real time. The American Gaming Association continues to compile monthly data through its tracker, which now covers dozens of states and provides the most consistent national view of how handle and revenue shift month to month. Operators and state regulators will examine the June and July reports closely to determine whether the pattern persists or whether volume returns to the licensed market.
Conclusion
The May 2026 results released by the American Gaming Association document a clear 1.8 percent revenue decline and 0.4 percent handle reduction for U.S. sports betting, and they mark the second straight month of contraction driven in part by sports-related activity moving to prediction market platforms such as Kalshi that operate outside standard state oversight. Casino gaming and iGaming posted offsetting growth, while sports betting tax collections fell in tandem with operator revenue. The Commercial Gaming Revenue Tracker supplies the underlying data that frames these outcomes for July 2026 and beyond.
