The Commodity Futures Trading Commission has shifted from a hands-off posture to declaring prediction markets subject to federal oversight, asserting exclusive jurisdiction and starting a formal rulemaking that focuses squarely on manipulation risk, participant protections, and how sports- and politics-related contracts are handled.
CFTC staff advisory Letter No. 26-08: what it does and who it names
The CFTC’s staff advisory, Letter No. 26-08, applies to all designated contract markets (DCMs) and explicitly links prediction markets to the Commodity Exchange Act framework, treating event contracts as swaps subject to Core Principles 3, 4, and 12. Under Chairman Michael Selig, the agency is no longer describing these platforms as outside federal law: the advisory requires DCMs such as Kalshi and Polymarket to show how they prevent manipulation, maintain surveillance, and protect participants.
The advisory also contains a jurisdictional pronouncement. The CFTC asserts exclusive federal authority over these contracts even as multiple states pursue litigation claiming power over sports betting. Selig’s office has signaled readiness to defend that view in court — filing amicus briefs and preparing for a possible Supreme Court review that could decide whether states or the CFTC have the final say on certain sports-related markets.
Concrete compliance steps DCMs must take
The advisory is operational, not merely declaratory: DCMs are asked to document surveillance systems, incident response workflows, and the specifics of how contracts are priced and settled. Exchanges are urged to avoid vague contract language that can mask manipulation risk and to develop protocols for detecting insider trading, with the CFTC continuing to rely heavily on DCM self-reporting when suspicious patterns surface.
| CEA Core Principle | Requirement for DCMs | Practical example |
|---|---|---|
| Principle 3 (Prevention of market manipulation) | Maintain surveillance and trade reviews | Algorithmic monitoring to flag abnormal position concentrations |
| Principle 4 (Transparent rules & surveillance) | Publish clear contract specs and enforcement policies | Publicly posted settlement criteria and trade cancellation rules |
| Principle 12 (Financial integrity) | Ensure clearing and margin arrangements | Clearing counterparties and default funds for event contracts |
Sports, politics and the legal fault lines
The CFTC’s rulemaking path is deliberate: the Advanced Notice of Proposed Rulemaking (ANPRM) asks more than 100 questions and gives stakeholders 45 days to comment on whether, and how, permanent rules should be written. That ANPRM explicitly revisits sensitive categories—contracts tied to terrorism, assassination, or war remain problematic—and follows the agency’s withdrawal of a 2024 proposed rule that would have banned political and sports event contracts outright.
That regulatory pause matters because several states are litigating to treat sports-related prediction contracts as gambling under state law. If a court — potentially the U.S. Supreme Court — rules against the CFTC’s asserted exclusivity, operators could face a patchwork of state bans, high licensing costs, and liquidity problems that have already made state-licensed attempts fragile. In public remarks and filings, Chairman Selig has emphasized that the agency will press its jurisdiction in court while the rulemaking process runs.
Practical checks: when operators and users should slow down or press ahead
Operators should treat the advisory and ANPRM as an operational checklist: beef up surveillance, clarify settlement mechanics, and proactively engage sports leagues or governing bodies when listing game-related contracts. Kalshi, for example, has publicly stepped up insider-trading detection protocols after high-profile suspicions; smaller platforms without similar investments in monitoring should consider pausing new contract launches until they can demonstrate compliance with the CEA principles the advisory cites.
Retail users and institutional participants need a different lens: prefer platforms that publish clear contract specifications, supply historical liquidity data, and disclose their surveillance and dispute processes. If a marketplace cannot show how it detects concentrated positions or how settlements are determined — or it declines to engage with relevant leagues or data providers for sports contracts — that is a practical stop signal.
Quick Q&A
Are prediction markets now federally regulated? The CFTC has announced it treats most event contracts as swaps under the CEA and has applied Letter No. 26-08 to DCMs, asserting exclusive jurisdiction, but final rules are still pending.
How soon will rules arrive? The ANPRM opens a 45-day comment window and asks over 100 questions; timing for permanent rules depends on that comment period and subsequent drafting, so change will be measured rather than immediate.
What should I watch as a user or operator? Watch for clear contract specs, published surveillance practices, league cooperation on sports contracts, and whether exchanges publicly commit to the CEA Core Principles highlighted in the advisory.
