CFTC issues alert as Kalshi enhances surveillance amidst insider trading probes

The Commodity Futures Trading Commission has reinforced its oversight authority following recent enforcement actions on Kalshi’s prediction platform, signalling a crackdown on misconduct and boosting confidence in regulated markets.

The Commodity Futures Trading Commission has issued an advisory that underscores its authority to oversee and, when necessary, prosecute misconduct in federally regulated prediction markets after two recent enforcement matters on the KalshiEX platform. According to the CFTC, the cases involved alleged misuse of material non-public information and fraudulent conduct, and the regulator reminded market operators of duties such as maintaining audit trails, conducting surveillance and enforcing prohibitions on insider trading, pre-arranged trades, disruptive trading and other manipulative schemes.

Kalshi has said it detected the trades through its surveillance systems and disciplined the accounts involved, while also expanding its compliance resources. The company announced the creation of an independent surveillance advisory committee, new partnerships with market-monitoring firm Solidus Labs and the Wharton Forensic Analytics Lab, and the appointment of Robert DeNault to head enforcement. In a company blog titled "Two Insider Trading Cases We’ve Recently Closed," Kalshi described its internal reviews and said it would disclose additional cases on its notices page.

CFTC leadership framed the advisory as part of a broader supervisory stance. In a post on X, CFTC Chairman Michael S. Selig said he was "pleased to see that our exchanges are adhering to their oversight responsibilities as self-regulated organizations …. Let me be clear: if you attempt to engage in manipulation, fraud, or insider trading, we will find you and take action." The Division of Enforcement said it will investigate and bring prosecutions where warranted, noting that while exchanges have primary day-to-day surveillance roles, the Commission retains full authority to police illegal trading on any designated contract market.

Details released by Kalshi and summarised by the CFTC indicate differing factual histories for the two cases. One involved a political candidate who placed a small trade on a contract listing him as an option for the 2026 California gubernatorial election and later posted about it on social media; Kalshi said it froze the account, imposed a ban and levied a financial penalty. The other case centred on an individual affiliated with a YouTube channel who traded on related contracts while allegedly possessing material non-public information; Kalshi reported non-cooperation in that investigation and imposed a longer suspension and a larger monetary sanction.

Independent press reporting and industry commentary place these actions in a wider pattern of intensified scrutiny of prediction markets. Media outlets have detailed the penalties and suspensions imposed by Kalshi in May, August and September 2025, and legal advisers have interpreted the CFTC advisory as signalling heightened enforcement risk for platforms and participants alike. The advisory is being read by market lawyers and compliance teams as a clear message that internal exchange discipline will be complemented by potential CFTC investigations and enforcement where apparent statutory violations arise.

The combined steps by Kalshi and the CFTC appear aimed at bolstering confidence in nascent, federally regulated prediction markets by strengthening surveillance, clarifying enforcement expectations and demonstrating consequences for trading on non-public information. Industry observers say continued investment in monitoring technology and independent oversight will be critical if such markets are to scale while meeting the Commodity Exchange Act's market-integrity standards.
