The Commodity Futures Trading Commission has released updated guidance on sports event contracts, designating registered exchanges as the first line of defense against market abuse, even as Kalshi surpasses $2 billion in weekly trading volume and over a dozen state attorneys general file lawsuits claiming these platforms constitute unlicensed sportsbooks. The regulatory standoff is reshaping how Americans bet on sports, threatening tribal casino revenues, and forcing DraftKings and FanDuel to pivot their entire business models toward federal derivatives frameworks.

CFTC Places Exchanges at Center of Sports Contract Compliance

What the New CFTC Guidelines Actually Say

The Commodity Futures Trading Commission’s new guidance does not ban sports prediction contracts. Instead, it formalizes a compliance structure in which designated contract markets, the federally registered exchanges that host these products, bear primary responsibility for monitoring trading activity, flagging manipulation, and enforcing contract terms. This is a significant shift in accountability, moving oversight away from state gaming regulators and firmly into the federal derivatives framework.

The CFTC’s position builds on its existing authority under the Commodity Exchange Act, which governs derivatives trading in the United States. Prediction market contracts on outcomes like NFL game winners or NBA championship results are classified as event contracts under this framework, not as sports wagers under state gaming law. That classification is the central legal dispute driving litigation across more than a dozen states.

Kalshi, the most prominent federally regulated prediction market, fought a protracted legal battle with the CFTC itself in 2024 before winning the right to list sports contracts. The company’s victory in federal court set the precedent that the CFTC, not state gaming boards, holds jurisdiction over these products. The new guidelines codify the post-litigation reality and assign Kalshi and similar platforms the operational burden of self-policing.

How Exchange-Level Enforcement Works in Practice

Under the CFTC framework, registered exchanges must maintain surveillance systems capable of detecting unusual trading patterns, coordinate with the commission on suspicious activity reports, and enforce position limits on individual contracts. These are standard requirements for commodity exchanges trading oil futures or interest rate swaps, now applied to markets predicting whether Patrick Mahomes throws three touchdowns on Sunday.

The practical challenge is scale. Kalshi’s sports contracts alone represent more than 75% of its total trading activity, and the platform processes millions of individual trades weekly across hundreds of active contracts [1]. Building surveillance infrastructure for that volume requires significant capital investment, which smaller prediction market entrants may struggle to match. This creates a structural advantage for well-capitalized platforms and raises barriers to entry that could consolidate the market around two or three dominant players.

Twelve-Plus States Sue Prediction Markets Over Unlicensed Betting Claims

The Legal Theory Behind State Lawsuits

More than a dozen state attorneys general have filed or joined litigation arguing that prediction market operators are running unlicensed sportsbooks in violation of state gaming statutes. The core legal theory is straightforward: if a consumer deposits money, selects a sports outcome, and receives a payout based on whether that outcome occurs, the transaction is sports betting regardless of what the federal government calls the underlying instrument.

States with robust regulated sports betting markets have the most to lose financially. New Jersey, for example, generated approximately $11.6 billion in sports betting handle in 2023 and collects a 13% tax on gross gaming revenue from licensed operators. Prediction markets operating under federal derivatives rules pay no equivalent state gaming tax, creating what state regulators describe as an unlevel playing field [1].

The litigation also carries a constitutional dimension. States argue the CFTC’s jurisdiction over event contracts improperly preempts state police powers over gambling, a regulatory domain traditionally reserved to states under the Tenth Amendment. Federal courts will ultimately decide whether the Commodity Exchange Act’s preemption language is broad enough to displace state gaming laws entirely, and that decision could take years to resolve through appeals.

Tribal Gaming’s High-Stakes Opposition

Tribal gaming leaders have emerged as some of the most vocal opponents of prediction markets, and their concern is specifically economic. In states like California, Arizona, and Florida where tribal compacts restrict or prohibit commercial online sports betting, prediction markets accessible via smartphone represent direct competition for gambling dollars that tribes currently capture through physical casinos and state-authorized mobile apps.

The National Indian Gaming Association has formally objected to the CFTC’s approach, arguing that federal derivatives regulation should not function as a backdoor to circumvent tribal gaming compacts negotiated under the Indian Gaming Regulatory Act. Tribal operators invested billions in physical infrastructure and paid substantial compact fees to states in exchange for market exclusivity. Prediction markets, in their view, undermine those agreements without any corresponding public benefit to the states involved. This conflict adds a politically powerful constituency to the coalition opposing CFTC-regulated sports contracts.

Kalshi Hits $2 Billion Weekly Volume as Traditional Sportsbooks Stall

Prediction Market Growth by the Numbers

Kalshi’s reported weekly trading volume exceeding $2 billion places it in a category that would have seemed implausible three years ago, when the platform primarily listed political and economic event contracts [1]. Sports contracts now dominate the platform’s activity, accounting for more than 75% of total volume, a figure that reflects both consumer demand and the competitive pricing advantages prediction markets offer over traditional sportsbooks.

The traditional U.S. sportsbook market, by contrast, has entered its first period of negative growth since the Supreme Court’s 2018 Murphy v. NCAA decision opened the door to state-by-state legalization. Handle figures from major regulated markets showed year-over-year declines in late 2024, a development that has prompted serious industry debate about whether prediction markets are cannibalizing licensed sportsbook activity or whether other factors, including market saturation and promotional pullbacks, explain the slowdown [1].

DraftKings and FanDuel, recognizing the structural tax disadvantage they face competing against federally regulated prediction markets, have both announced plans to launch their own event-contract platforms operating under CFTC oversight. This strategic pivot allows them to offer prediction-style products without the 10-51% state gaming tax burden that applies to their licensed sportsbook operations. It also signals that the two largest U.S. sportsbook operators believe the federal prediction market model is durable enough to build a business around.

The tax arbitrage is the central economic fact in this story. A licensed New York sportsbook pays 51% of gross gaming revenue to the state. A CFTC-regulated prediction market operating in New York pays no equivalent levy. That difference, compounded across billions in weekly volume, represents a competitive advantage that traditional operators simply cannot absorb indefinitely without regulatory parity [1].

What This Regulatory Fight Means for Sports Bettors and Racing Fans

For sports bettors already active on DraftKings, FanDuel, or BetMGM, the prediction market battle has direct practical implications. If state lawsuits succeed in shutting down or restricting CFTC-regulated sports contracts, the competitive pressure that has kept sportsbook margins relatively tight may ease, potentially affecting the odds and promotions available to consumers. Conversely, if prediction markets expand freely, bettors gain access to a new class of contract-based products with different pricing mechanics than traditional point-spread or moneyline wagers.

Horse racing bettors operate in a separate but instructive parallel. Pari-mutuel wagering on thoroughbred and harness racing has long functioned under a federal framework, the Interstate Horseracing Act of 1978, that coexists with state racing commissions. The prediction market dispute echoes that dual-jurisdiction structure, and racing industry stakeholders are watching closely to see whether the CFTC model expands or contracts, since any precedent set in sports event contracts could eventually touch racing-related derivatives products.

The immediate practical reality for bettors in 2025 is that prediction markets are accessible and legal at the federal level, but their long-term availability in specific states remains uncertain pending court outcomes. Bettors considering these platforms should monitor state-level litigation developments, particularly in states where attorneys general have filed active suits, before committing significant activity to prediction market accounts.

Key Takeaways

• The CFTC’s new guidelines designate registered exchanges like Kalshi as the primary compliance enforcers for sports prediction contracts, not state gaming regulators.
• Kalshi reports weekly trading volumes exceeding $2 billion, with sports contracts representing more than 75% of total platform activity [1].
• More than a dozen state attorneys general have filed lawsuits arguing prediction market operators are conducting unlicensed sports betting in violation of state law.
• The established U.S. sportsbook market recorded its first stretch of negative growth since 2018 legalization, raising questions about prediction market cannibalization [1].
• DraftKings and FanDuel are both developing CFTC-regulated event-contract platforms to compete without the 10-51% state gaming tax burden applied to licensed sportsbooks.
• Tribal gaming operators, represented by the National Indian Gaming Association, oppose prediction markets as a threat to compact-protected revenue in states without commercial online betting.
• The constitutional question of whether the Commodity Exchange Act preempts state gaming law will likely require federal appellate court resolution, a process that could extend into 2026 or beyond.

Frequently Asked Questions

The Bottom Line

The CFTC’s decision to position exchanges as the first line of defense is a pragmatic response to a market that has grown faster than any regulatory body anticipated. Kalshi crossing $2 billion in weekly volume is not a curiosity, it is a signal that consumer demand for contract-based sports products is real, large, and accelerating. The commission is essentially acknowledging that it cannot supervise this market alone and is delegating front-line compliance to the platforms best positioned to monitor their own trading activity.

The state lawsuits will not resolve quickly. Constitutional preemption fights involving federal commerce authority and state police powers routinely take three to five years to reach definitive appellate conclusions. In that window, prediction markets will continue operating, volumes will likely grow, and the tax revenue gap between licensed sportsbooks and CFTC-regulated platforms will widen. That pressure alone may force Congress to act, either by clarifying CFTC jurisdiction or by creating a federal sports betting framework that resolves the conflict legislatively rather than through litigation.

The industry that emerges from this fight will look fundamentally different from the one that existed before Kalshi’s 2024 court victory. Whether prediction markets end up regulated as derivatives, as gambling products, or as some hybrid category yet to be defined, the $2 billion weekly volume figure tells you everything you need to know about where the money is going. The regulatory framework will follow the money, as it always does.
