Kalshi, as the leading CFTC-registered DCM for event contracts, continues to drive self-certification activity for sports outcomes through its established sports markets and high trading volume. Recent CFTC Division of Market Oversight advisories in March and July 2026 clarified procedures for sports-related and series-based self-certifications under Regulation 40.2, emphasizing detailed analysis, pre-filing engagement with leagues, and avoidance of overly broad templates while affirming that compliant filings can proceed without prior approval. This guidance, paired with the agency's withdrawal of restrictive proposals and assertion of federal preemption over state gaming claims, has reduced barriers and encouraged DCMs like Kalshi and potential new entrants such as Aristotle Exchange to pursue listings ahead of the December 31, 2026 deadline. Competitive dynamics hinge on filing specificity, league cooperation, and any last-minute regulatory stays.
