George Santos–Kalshi Betting Scandal

The story so far

As of August 31, 2026

George Santos is now the first person barred for life from Kalshi. The platform’s compliance unit imposed a permanent ban effective August 29, 2026, and a $71,356 penalty, after finding he manipulated a market tied to his own conduct and did not cooperate with its inquiry. That penalty closes an internal review triggered by trades Santos made around whether he would attend President Donald Trump’s 2026 State of the Union address.

What makes this case different is control and price-moving statements. In February, Santos placed large wagers on whether he would attend the address, an outcome he alone could decide, then made public claims that he would be there while holding positions that profited if he was not. He skipped the event and cleared roughly $17,800. Kalshi rules bar trading when a user can influence the result, and its filing says his posts moved prices in his favor.

The platform had already referred the trades to federal regulators. In July, the Commodity Futures Trading Commission, the federal derivatives regulator, ordered Santos to pay $35,000, give back $17,569.98 in profits, and accept a three-year trading ban. Kalshi’s lifetime bar goes further than other recent cases because, unlike several candidates who admitted to smaller violations and took three-year bans, Santos did not cooperate with the platform’s investigation.

The story has become a test of whether prediction markets can police people with special access or power over outcomes. Kalshi has been adding guardrails, including a risk-scoring system, employment checks for sensitive markets, and a surveillance partnership with Nasdaq. On the same day as the Santos decision, it fined and suspended multiple political figures for betting on their own races, including North Carolina House candidate Laurie Buckhout, who paid just under $2,600 and received a three-year ban, and former Maine gubernatorial candidate Ben Midgley, who was also barred for three years. Santos’s lifetime ban is now the benchmark for cases that combine control over an outcome with attempts to sway market prices and refusal to cooperate.
