The Commodity Futures Trading Commission has told regulated prediction market platforms not to display event contract prices as American-style moneyline odds, saying prices should be shown in nominal or percentage terms instead.
The guidance, released publicly in a staff letter on Aug. 7, 2026, matters because it draws a clearer line between CFTC-regulated event contracts and sportsbook-style wagering. It also comes as prediction markets face continued scrutiny over whether some products are lawful derivatives or unlawful gambling.
The reminder came from the CFTC’s Division of Market Oversight and Market Participants Division. According to the agency, firms under its jurisdiction must follow U.S. laws governing derivatives products and avoid deceptive listing, promotion, or advertising of event contracts.
The CFTC said sportsbook-style plus-or-minus odds can confuse users about the nature of the instruments. Prediction market contracts are typically priced in nominal terms, such as 40 cents, which would imply roughly a 40% chance of the event occurring. By contrast, bookmaker-style formats such as +150 or -200 look like traditional sports betting odds.
CFTC says moneyline pricing may mislead users
The agency said derivatives should be displayed in terms that accurately reflect market-based pricing, specifically nominal values or percentages. It warned that showing event contracts as bookmaker-style odds may mislead participants and may also reduce visibility into market depth or price impact.
The staff letter also referenced research indicating that American-style wagering formats can encourage greater risk-taking in sports-related betting. The CFTC said misleading pricing displays could create risks under federal prohibitions on manipulative devices.
Importantly, the guidance does not ban the contracts themselves. It is focused on how those contracts are presented to users.
What platforms may need to change next
The CFTC did not identify a full list of affected platforms in the source material, but the guidance applies to regulated prediction market firms under its supervision. Kalshi said it would comply with the guidance by the Aug. 31, 2026 deadline mentioned for confirming receipt of the letter.
The move lands amid broader disputes between federal regulators and state authorities over sports-related event contracts. Several states have argued that some prediction market offerings amount to unlicensed gambling, while the CFTC has said the instruments fall under its exclusive federal authority as derivatives.
What remains unclear is whether other platforms will make immediate display changes and whether the CFTC will pursue enforcement tied to past or future pricing formats. For now, the agency’s message is narrower: prediction markets can keep offering regulated event contracts, but they should not make them look like sportsbook bets.
