The Commodity Futures Trading Commission has told prediction markets and intermediaries that displaying event contract prices in American sportsbook-style odds is likely misleading and could violate federal anti-manipulation law.
The CFTC issued the reminder to prediction markets operators last week.
As prediction markets fight state gambling regulators across the country, the CFTC is telling the industry that if it wants event contracts treated as federally regulated derivatives, it cannot present them to consumers with standard sports betting odds.
CFTC targets American odds
In a joint letter, the CFTC’s Division of Market Oversight and Market Participants Division reminded regulated entities that they must give consumers clear and accurate pricing information when listing, soliciting or accepting event-contract trades. That responsibility also applies to their affiliated entities, partners and intermediaries.
The agency specifically called out American odds, or the familiar plus/minus format such as +150 or -200, saying bookmaker-style displays are likely to mislead participants about the transaction they are entering and can obscure market depth and the price impact of a trade.
American odds show prospective payout relative to a $100 stake. By contrast, the CFTC wants derivatives priced in nominal or percentage terms that reflect a market-generated price, such as a contract trading at 62 cents or reflecting a 62% implied probability.
Why prediction markets pricing matters
The CFTC said users should be able to tell when they are buying an event contract on a regulated exchange rather than placing a higher-margin wager through a bookmaker. Its position is that transparent, market-driven contract prices, together with visible bid and ask information, are core features of a derivatives market.
The warning also carries an enforcement edge. The divisions said misleading price displays for any CFTC-regulated product may run afoul of federal prohibitions on manipulative or deceptive devices.
The letter went to event contract exchanges, futures commission merchants and introducing brokers, which must acknowledge receipt by Aug. 31.
CFTC draws its line
The guidance lands as CFTC-regulated platforms increasingly offer sports contracts that look familiar to bettors. Traders can purchase contracts on game winners, player performance and other sports outcomes. The format of those products has become part of the central dispute over what they actually are.s
State regulators argue the platforms are offering unlicensed sports betting, often without state gaming licenses, taxes, responsible gambling rules or the operator oversight required of sportsbooks. The CFTC and the platforms counter that the contracts are federally regulated derivatives, with the CFTC holding exclusive authority over the exchanges that list them.
The commission’s message is clear: displaying a +120 moneyline alongside a sports contract makes its legal argument harder. A market priced contract shown as a 55-cent “Yes” price is much easier to characterize as a federally supervised derivative.
Lawsuits across the country
The distinction between financial product and sports bet matters because prediction markets are embroiled in litigation with gambling regulators across the country. Courts have reached conflicting conclusions on whether the Commodity Exchange Act preempts state gambling laws when CFTC-registered exchanges list sports event contracts.
Kalshi has won meaningful preemption rulings, including in New Jersey and Minnesota, but it has also faced adverse decisions in New York and Utah, while Nevada courts have treated its sports contracts as unlicensed gambling. Those competing results have turned product presentation, including pricing and market structure, into more than a consumer experience question.
The CFTC has separately sued states that tried to restrict federally registered event-contract platforms and has filed briefs defending its exclusive jurisdiction. By telling operators to stop making contracts look like sportsbook wagers, the agency is strengthening that same federal market argument in the product itself.
The letter signals that the CFTC wants prediction markets to act, and look, like the derivatives exchanges it says they are. Whether that is enough to persuade skeptical state courts remains unresolved, but the regulator is making sure the industry does not hand its opponents an easier argument.
