U.S. Department of Justice Probes George Santos Over Alleged Kalshi Insider Trading

Kalshi froze George Santos’s account and alerted the CFTC and DOJ after suspicious trading tied to a State of the Union contract, intensifying scrutiny of prediction-market safeguards and self-referential trading risks.

Fact Check
NPR's June 2, 2026 report provides the primary account with specific operational detail: Santos allegedly bet against his own attendance at the February 2026 SOTU, posted videos to inflate odds, then skipped the event for profit; Kalshi froze his account and referred the matter to both CFTC and DOJ. The Guardian independently corroborates via Punchbowl News, specifying DOJ Public Integrity Section involvement and Kalshi's confirmation of cooperation. Business Insider, Crypto Briefing, and Crypto.news further corroborate the dual DOJ/CFTC probe and Kalshi account freeze. No conflicting reporting was found. The only minor inconsistency is Guardian's reference to '2024 State of the Union' which appears to be an editorial error; NPR and Crypto Briefing consistently identify the February 2026 SOTU.
Summary

The U.S. Department of Justice is investigating former congressman George Santos over alleged insider trading tied to Kalshi, after suspicious trading linked to a State of the Union event contract prompted the platform to freeze his account and alert regulators. According to NPR and earlier reporting, Santos reportedly made tens of thousands of dollars on Kalshi, and the case centers on whether he traded using direct, non-public knowledge in a market tied to an event he could know about in advance. The matter has been referred to the Commodity Futures Trading Commission and the DOJ, and it comes amid broader scrutiny of prediction markets including Kalshi and Polymarket, with the incident highlighting concerns about self-referential trading abuses.
