A Senate Banking subcommittee on Wednesday convened the most consequential gambling industry hearing in years, with the heads of the American Gaming Association, Kalshi, and FanDuel facing pointed questions about prediction markets, federal oversight, and the rapidly blurring line between financial derivatives and sports betting. The political tension is now openly hostile: Bill Miller, CEO of the American Gaming Association, called the CFTC "a rogue agency making a mockery of congressional intent," while Kalshi maintained that its event contracts are regulated financial products, not gambling. The hearing comes as 41 state attorneys general have formally asked the CFTC to halt federal enforcement that's overriding state authority, and Minnesota became the first state to ban prediction markets outright.
Quick answer: A US Senate Banking subcommittee held a major hearing May 20-21 examining sports betting and prediction markets. AGA leadership called Kalshi and Polymarket "backdoor sports betting operations." Kalshi argued its event contracts are federally regulated futures products, not gambling. 41 state AGs have asked the CFTC to stop preempting state regulation. Minnesota became the first state to ban prediction markets within its borders, triggering legal challenges from Kalshi.
The Core Dispute
The fight is fundamentally about jurisdiction. Prediction markets like Kalshi and Polymarket argue their offerings are "event contracts" — financial derivatives that pay out based on real-world outcomes, regulated by the Commodity Futures Trading Commission under federal authority. State regulators and traditional sportsbooks argue these are functionally sports bets disguised as derivatives — and should be regulated as gambling, requiring state licenses and consumer protections.
The economic stakes are enormous. Kalshi's NFL and NBA event contract handle has grown to roughly $4 billion annually in just two seasons. If those contracts are reclassified as gambling, Kalshi must obtain state licenses (currently impossible in most states for a non-traditional operator) or shut down its sports product. If they remain federal derivatives, traditional sportsbooks lose significant market share and tax revenue.
Key Testimony Highlights
Bill Miller, AGA CEO: "These platforms are conducting unlicensed, untaxed sports betting under the false flag of financial derivatives. They have evaded every consumer protection requirement that our member companies have invested billions to comply with."
Tarek Mansour, Kalshi CEO: "Event contracts are not gambling. They are price-discovery instruments regulated by the CFTC for over a decade. We have submitted to federal oversight, registered all required disclosures, and operate with full transparency."
Senator Lummis (R-WY): "I have no problem with sophisticated traders hedging political risk. I have a serious problem with retail consumers being marketed sports event contracts that look identical to a parlay."
Senator Warren (D-MA): "The CFTC has failed to demonstrate it has the staffing, data infrastructure, or expertise to oversee a market that has grown 40-fold in 24 months."
The Minnesota Ban
Earlier this month, Minnesota Governor Tim Walz signed legislation explicitly prohibiting prediction market operators from accepting Minnesota residents. Kalshi has filed a federal lawsuit arguing the state ban is preempted by CFTC authority — setting up a constitutional showdown between state gambling regulation and federal commodities law.
The Minnesota case is widely viewed as the test case for the broader regulatory framework. If Kalshi prevails, it sets precedent for federal preemption of all state gambling laws targeting event contracts. If Minnesota prevails, prediction markets face a state-by-state regulatory hurdle that could shut them down in major markets.
The 41-State AG Letter
In April, 41 state attorneys general signed a joint letter to the CFTC demanding the agency cease approving sports-related event contracts. The letter argues that the CFTC has overstepped its statutory authority by allowing what are effectively gambling products without consultation with state regulators who have constitutional authority over gambling within their states.
The letter has not produced a CFTC retreat. Instead, the agency has approved additional contract types, including political event contracts that drew controversy in the 2024 election cycle. CFTC Chair Rostin Behnam testified Wednesday that the agency views its statutory mandate as encompassing event contracts and that it will continue approving compliant offerings.
Industry Position: AGA vs Kalshi
The American Gaming Association has emerged as the most vocal industry opponent of prediction markets. AGA members — including DraftKings, FanDuel, MGM, Caesars, and Penn Entertainment — argue that prediction markets undermine the state-regulated framework they have built. State licenses, integrity monitoring, responsible gambling tools, and tax obligations are required of every AGA member but not required of Kalshi or Polymarket.
DraftKings has taken the additional step of exploring its own event contract registration with the CFTC. If DraftKings successfully registers, it could offer prediction-market-style products on a federally regulated basis — effectively legitimizing the model while putting competitive pressure on Kalshi. We covered this strategic move in our earlier reporting on latest articles.
The Insider Trading Concern
One particularly damaging revelation at the hearing: a US soldier was recently indicted for allegedly using classified information about military operations to make wagers on Polymarket. Senator Warner cited the case as evidence of inadequate regulatory oversight: "If a sergeant in the Air Force can use classified information to bet on geopolitical events, what does that say about the integrity controls of these platforms?"
Kalshi responded that it has implemented expanded insider trading detection and disclosure requirements. Polymarket has not testified in public hearings but issued a written statement defending its platform's compliance with US law.
What This Means for Consumers
For US gamblers, the regulatory uncertainty creates real risk. Players in states where prediction markets are explicitly banned (currently Minnesota only) cannot legally participate, but enforcement is sporadic. Players in states with no explicit ban operate in legal gray territory — federal preemption may or may not protect them from state enforcement.
For practical players, the safer route remains state-licensed sportsbooks. Operators like DraftKings, FanDuel, BetMGM, and Caesars are explicitly licensed in every market where they operate, with full consumer protection and responsible gambling tools.

Likely Outcomes
Three scenarios are now in play:
- CFTC continues approving event contracts (status quo): Kalshi and Polymarket continue operating under federal oversight. State bans are challenged in federal court.
- Congress legislates clarity: A new statute defines event contracts vs gambling explicitly. This is the cleanest path but the slowest — likely 18-24 months.
- Supreme Court intervention: If state-versus-federal challenges reach SCOTUS, a definitive ruling on federal preemption would set permanent precedent.
Industry Stocks React
Sports betting stocks rallied modestly after the hearing as investors interpreted Congressional scrutiny as a potential headwind for prediction markets. DraftKings was up 4.2 percent at close Friday, FanDuel parent Flutter up 3.1 percent. Penn Entertainment held flat. The market interpretation: any framework that restricts prediction markets is positive for traditional sportsbooks.
Frequently Asked Questions
What is a prediction market?
A prediction market is a platform where users buy and sell contracts based on the outcome of future events — elections, sports, economic data, geopolitical events. Contracts trade like financial securities, with prices reflecting market consensus probability.
Are Kalshi and Polymarket legal in the US?
Kalshi operates with CFTC approval as a regulated derivatives exchange. Polymarket operates internationally but has limited US access. Minnesota has explicitly banned both. Other states have not formally addressed prediction markets.
What is the AGA's position?
The American Gaming Association argues prediction markets are unlicensed sports betting and should be regulated as gambling under state authority, not federal commodities law.
What happens if Congress legislates?
A new federal statute could define event contracts versus gambling clearly. The likely framework would give states authority over sports-related event contracts while preserving CFTC authority over financial and political contracts.
How does this affect regular sports bettors?
For sports bettors using state-licensed operators like DraftKings or FanDuel, the regulatory dispute has no direct impact. For bettors using prediction markets, your access may be restricted depending on state and outcome of legal challenges.
Conclusion: A Watershed Moment for Industry Regulation
Wednesday's Senate hearing marks the moment when prediction markets stopped being a niche regulatory question and became a mainstream political issue. The CFTC versus state regulators showdown is now formally underway. For the gambling industry, the next 12 months will likely produce either Congressional clarity, Supreme Court precedent, or both. For consumers, the practical recommendation remains unchanged: use licensed, state-regulated operators for sports betting.
