CFTC uses AI to police Polymarket

The Commodity Futures Trading Commission is tightening its grip on prediction markets from two directions at once. In interviews published this week, Chairman Michael Selig said the agency is using artificial intelligence and outside analytics tools to look for insider trading and U.S. users accessing offshore venues such as Polymarket through virtual private networks. Two days earlier, CFTC staff issued a no-action letter that eases some swap-data reporting and recordkeeping obligations for fully collateralized event contracts listed and cleared by regulated venues. Together, the moves show a regulator trying to expand surveillance while reducing a specific compliance burden for approved market operators. ### Why is Polymarket in the CFTC’s sights now? Michael Selig told WIRED that the agency is actively searching for suspicious trading in prediction markets, including Polymarket, and said U.S. traders using workarounds to reach offshore platforms should expect enforcement. WIRED reported that the CFTC is using AI as part of that effort and is examining trading patterns for signs of manipulation or insider dealing. (wired.com) April 23, 2026, gave the agency a fresh enforcement example. The CFTC said it sued Gannon Ken Van Dyke, an active-duty U.S. Army service member, alleging he used classified nonpublic information about an operation involving former Venezuelan President Nicolás Maduro to trade on Polymarket. The Justice Department unsealed parallel criminal charges the same day. (wired.com) ### What exactly did the no-action letter do? On May 13, 2026, the CFTC’s Division of Market Oversight and Division of Clearing and Risk said they would not recommend enforcement against designated contract markets, derivatives clearing organizations, or their participants for failing to meet certain swap-related recordkeeping rules and for failing to report data associated with fully collateralized event contract transactions to swap data repositories. (cftc.gov) The relief applies only on the terms set out in the letter. CFTC staff said the position responded to numerous requests from exchanges and clearinghouses that list and clear event contracts. The agency said the new approach is meant to provide uniform treatment and avoid issuing repeated, nearly identical letters as more venues seek the same treatment. ### Which firms does that relief help? The May 13 letter says the position covers all beneficiaries of previous no-action letters on similar contracts. (cftc.gov) It also says entities that want to list or clear similar contracts may request an identical no-action position and, if granted, will be added to an appendix to the letter. That matters because Polymarket itself is not a U.S.-regulated designated contract market. (cftc.gov) The reporting relief is aimed at venues and clearing organizations operating inside the CFTC’s framework, while Selig’s comments about surveillance reached offshore platforms as well. That split leaves regulated U.S. operators with less reporting friction even as the agency says it is stepping up scrutiny of trading behavior across the sector. ### Is the agency treating event contracts more like derivatives than gambling? February 17, 2026, offered Selig’s clearest public view on that question. In a statement posted by the CFTC, he said the agency has overseen prediction markets for decades and described event contracts as instruments that can help participants hedge risk and aggregate information. (cftc.gov) May 12 and May 15 added the enforcement side of that position. Selig said the CFTC is talking with major sports leagues about policing insider trading, according to CoinDesk, and told WIRED that prediction markets are subject to the same market-integrity concerns that apply elsewhere in derivatives trading. The agency’s April case against Van Dyke gave that stance a test case in court. (cftc.gov) ### What happens next for platforms and traders? The May 13 no-action letter sets up a process for additional exchanges and clearinghouses to seek identical treatment from CFTC staff, with successful applicants added to the appendix rather than receiving separate bespoke letters. That gives market operators a defined path to request the same reporting relief. (coindesk.com) The next concrete milestone is in court. The CFTC’s April 23 civil case against Van Dyke in the Southern District of New York, alongside the Justice Department’s criminal prosecution, will test how aggressively U.S. authorities can apply insider-trading theories to event contracts tied to offshore prediction markets.
