On 20 April 2026, Utah Senator John Curtis introduced federal legislation that would legally define prediction markets as gambling, directly challenging the commodities-law framework that platforms like Kalshi and Polymarket have relied on to operate sports event contracts across the United States.
The bill arrived four days after CFTC Chair Michael Selig spent the better part of a working day in front of the House Committee on Agriculture defending the agency's posture on the same products — a sequence that is not coincidental, and that significantly raises the political temperature around prediction-market regulation in 2026.
What the bill actually says
Stripped to essentials, the Curtis bill does three things:
1. Reclassifies sports event contracts as gambling under federal law. Once classified as gambling, the products fall outside the CFTC's primary jurisdiction and back inside the state-by-state regulatory architecture that governs the licensed sports-betting industry. 2. Returns enforcement authority to state gaming commissions. Where today the CFTC has been the de facto federal cop on sports event contracts, the bill would explicitly recognise state authority to license, restrict or prohibit the products within state borders. 3. Creates a federal definitional baseline. The bill draws an explicit line between commodities-style event contracts (geopolitical, economic, weather) and sports-outcome contracts, the latter being captured by the gambling classification.
The intent is unambiguous: prevent prediction-market operators from using federal commodities law as a workaround for state-level sports-betting prohibitions and licensing fees.
The bill is not anti-prediction-market. It is anti-arbitrage. The author's view, plainly stated, is that a sports event contract is a sports wager, and trying to call it something else for jurisdictional convenience is bad public policy.
Why this is happening now
Three forces converge to explain the timing.
The first is regulatory. The CFTC is moving toward formal rulemaking on event-contract oversight (covered in detail in our CFTC Selig prediction-markets hearing analysis), but rulemaking is slow. Curtis is offering Congress a faster, more decisive alternative.
The second is competitive. Licensed sportsbooks have spent the last four years paying for state licences, taxes, responsible-gambling tooling and compliance infrastructure. Watching prediction-market platforms offer functionally equivalent products without the same regulatory burden has produced sustained lobbying pressure.
The third is electoral. Several state attorneys general — including in Massachusetts, Nevada and New Jersey — have been actively challenging prediction-market operators. A clean federal definition would either validate or invalidate those state actions; the Curtis bill chooses validation.
What it would mean if it passes
The honest answer is that it almost certainly will not pass in its current form. Federal gambling legislation faces structural headwinds that have nothing to do with the merits — the topic has not produced clean federal action since UIGEA in 2006, and the political appetite for picking winners between licensed sportsbooks and prediction-market platforms is genuinely limited.
What the bill *will* do, regardless of whether it passes, is:
- Pull the political centre toward state-level enforcement. Even without a vote, the bill legitimises the position that prediction-market sports contracts are gambling-equivalent, giving cover to state regulators acting under their own authority. - Inform the CFTC's rulemaking timeline. Selig's testimony explicitly left state pre-emption open. The Curtis bill puts a thumb on the scale in favour of state authority being preserved. - Force prediction-market platforms to engage federally. Until now, lobbying has been piecemeal. A live bill changes that posture.
The international parallel
The US is not alone in trying to figure out where to draw this line. The UK Gambling Commission has held similar internal discussions about whether prediction-market-style products fall under the Gambling Act, and several EU regulators are working through equivalent classification questions in parallel. We touched on the wider European trajectory in our Europe iGaming policy shift breakdown.
The shared instinct, across jurisdictions, is to treat economic substance over legal form — if a product behaves like a sports wager and is consumed like a sports wager, regulators are increasingly inclined to call it one.
What this means for players using prediction markets
Three practical takeaways:
1. Federal classification is genuinely uncertain. Anyone treating prediction-market sports contracts as a permanent regulatory loophole is mispricing the policy risk. 2. State-level action is the more immediate threat. The bill amplifies state authority to act; expect state-level enforcement actions to escalate over the next twelve months. 3. Consumer protections are weaker on prediction-market platforms than on licensed sportsbooks. Self-exclusion enforcement, dispute resolution and fund segregation are not yet at parity. That is true today regardless of how the legal classification eventually settles.
The BettingPair view
The Curtis bill is the most substantive federal legislative move on prediction markets to date. It is unlikely to become law in its current form, but it does not need to in order to reshape the conversation. Combined with the CFTC's pending rulemaking and active state enforcement, the practical regulatory environment for prediction-market sports contracts is meaningfully tighter than it was a month ago.
For licensed sportsbook operators, that is good news. For prediction-market platforms, the regulatory cost of doing business in the US just went up. For players, the right posture is exactly the one we recommended in our CFTC hearing coverage — separate accounts, separate bankrolls, and don't assume parity of consumer protection.
