The Commodity Futures Trading Commission’s Division of Market Oversight and Market Participants Division reminded regulated entities involved in listing, soliciting or accepting event contracts that pricing and marketing must clearly and accurately represent the products as exchange-traded derivatives. Staff warned that displaying prices in the American odds format used by gambling bookmakers is likely to mislead participants about the nature of the transaction and may obscure market depth and pricing impact. Entities should distinguish event contracts traded at market-determined prices on CFTC-regulated exchanges from higher-margin, non-market-priced bookmaking products. Designated contract markets are expected to oversee intermediaries, affiliates and partners, while all covered entities should assess their pricing displays, marketing materials and other information for compliance. Misleading practices may violate federal prohibitions on manipulative or deceptive conduct. CFTC-regulated entities that list, solicit or accept event contract orders must review their own and their partners’ pricing and marketing practices and confirm receipt of the letter by Aug. 31, 2026.
