Kalshi Issues First Lifetime Ban for Republican Politician over Insider Bets
Prediction market platform Kalshi imposed its first-ever lifetime trading ban since its 2021 launch on Republican politicians Laurie Buckhout and George Santos for insider trading on event contracts. Santos was permanently suspended from trading and fined $71,356, while Buckhout received a three-year suspension and a $2,590 penalty. The sanctions stem from investigations into manipulation of event contracts linked to their own actions, marking a significant crackdown amid growing regulatory scrutiny of prediction markets in the U.S.
Accusations and Sanctions against Politicians
Kalshi accused Laurie Buckhout, a US House candidate from North Carolina, and former Republican lawmaker George Santos of trading on insider information involving event contracts tied to their political activities.
Santos was permanently banned from trading on the platform and fined $71,356, while Buckhout received a three-year suspension and a $2,590 fine.
Kalshi’s rules prohibit traders who can influence the outcome of underlying events from trading contracts on those events directly or indirectly. Buckhout’s case involved announcing her candidacy, which triggered related contracts, while Santos’s trading was connected to his attendance at the 2026 State of the Union address.
Responses and Cooperation with the Platform
Buckhout cooperated with Kalshi’s compliance inquiry and accepted the sanctions and trading ban.
In contrast, Santos did not appear to cooperate, which explained the harsher penalty of a permanent ban, according to experts.
Melinda Roth, a visiting law professor, described Santos as a 'status-based' trader — someone capable of determining event outcomes and thus manipulating the contracts.
Political Reactions and Market Status
Following the sanctions announcement, Santos called Kalshi an 'unserious company' in a post on X (formerly Twitter).
Buckhout admitted that betting on her own congressional race was a "dumb mistake."
As of the report, Kalshi still listed event contracts for Buckhout’s North Carolina race, with Democratic incumbent Don Davis favored at a 63% chance over Buckhout’s 41%.
Legal Context and Regulatory Pressure
Kalshi and other prediction platforms like Polymarket face lawsuits from state gaming authorities alleging they facilitate illegal betting on sporting and political events.
Meanwhile, Michael Selig, chair of the US Commodity Futures Trading Commission (CFTC), asserts the agency has exclusive jurisdiction over prediction markets and vows to sue states challenging this authority.
In August, the CFTC invoked emergency powers to block New York State’s attempt to bar Kalshi from offering contracts tied to sports and elections, highlighting escalating regulatory battles.
Why it matters
This development underscores growing regulatory and platform-level resolve to combat manipulation and insider trading within prediction markets. By imposing a permanent ban on a politician for insider trading, Kalshi sets an industry precedent and signals zero tolerance for trading that can affect contract outcomes. Set against the backdrop of escalating legal disputes between federal and state regulators, such enforcement reflects the prediction market sector’s push to foster trust and transparency while mitigating fraud and market manipulation risks.
