The CFTC's Division of Market Oversight published Letter No. 26-08 directing registered exchanges on compliance and listing requirements for event/prediction contracts and launched an Advanced Notice of Proposed Rulemaking (ANPRM) to solicit public comment on whether new or amended rules are needed (comments due 45 days after Federal Register publication). Chairman Michael Selig said the agency will defend its jurisdiction as states increasingly view sports-linked platforms as unlicensed gambling. The advisory reminds exchanges that insider-trading and manipulation prohibitions apply, flags risks for sports contracts tied to injuries or single-player actions, urges coordination with leagues, and notes the CFTC can halt noncompliant listings.

The CFTC issued formal guidance (Division of Market Oversight Letter No. 26-08) and opened an ANPRM seeking rule changes (comments due 45 days), warned exchanges that insider-trading and manipulation rules apply, highlighted specific risks for sports-linked contracts, and stated it can halt noncompliant listings—concrete regulatory actions likely to constrain prediction-market platforms. These are direct facts from the advisory and ANPRM notice.
