Senate Prediction Market Hearing: What Bettors Need to Know About the Federal Crackdown Taking Shape

Sports bettors and prediction market users should pay close attention to what happened in Washington on Wednesday, May 20. The Senate Commerce Subcommittee on Consumer Protection held a hearing titled “No Sure Bets: Protecting Sports Integrity in America,” and the outcome suggests federal regulation of platforms like Kalshi and Polymarket is no longer a distant possibility. Subcommittee chair Sen. Marsha Blackburn (R-Tenn.) called it the first of “several” planned hearings, and said she plans to confer with Commerce Committee chair Sen. Ted Cruz (R-Texas) about a legislative path forward.

The hearing was notable for its bipartisan tone. Both Republican and Democratic senators expressed skepticism about prediction markets, which operate under the Commodity Futures Trading Commission rather than under the state gaming regulations that govern sportsbooks like FanDuel and DraftKings. Senators questioned whether CFTC oversight provides the same consumer protections, problem gambling safeguards, and match-fixing controls that state-regulated sports betting markets provide.

The Core Dispute

Cruz framed the fundamental issue in his opening remarks, saying prediction markets “for all intents and purposes are sports bets” when they offer event contracts tied to sporting outcomes. The American Gaming Association, represented by CEO Bill Miller, testified that prediction markets are costing state governments substantial tax revenue and effectively operating as unregulated sportsbooks. Patrick McHenry, advising the Coalition for Prediction Markets, argued that the CFTC already provides robust oversight and that Congress should study the issue more before acting.

The hearing also touched on recent scandals involving alleged insider trading on prediction markets and concerns about advertising to young people. Blackburn cited examples of government officials potentially using inside information to place contracts on events they had knowledge of in advance, a concern that highlights the unique risks prediction markets create compared to traditional sports wagering.

What This Means for Sports Bettors

The practical implications depend heavily on what any legislation actually does. If Congress imposes state-level compliance requirements on prediction markets, platforms like Kalshi and Polymarket could face significant restrictions or be required to obtain licenses in each state, similar to traditional sportsbooks. DraftKings and FanDuel, which have both launched prediction market products, could also see those products subjected to new rules.

Blackburn said the core question for Congress is whether to establish minimum federal standards while allowing states to set stricter rules on top, or whether to leave regulation entirely to states. Currently, sports betting is legal in 39 states and Washington, D.C., while prediction markets operate across all 50 states under CFTC oversight. The CFTC is already in court with Minnesota over that state’s decision to make sports event contracts a felony. Further hearings are expected, with Blackburn indicating Congress will not drop the issue after one session.
