Kalshi permanently banned former Rep. George Santos and fined him $71,356 after finding that he traded on whether he would attend President Donald Trump’s February 24, 2026 State of the Union address, an event whose outcome he could personally affect. The sanction, described in Kalshi’s disciplinary notice as its first lifetime ban, followed a separate July 31, 2026 Commodity Futures Trading Commission settlement over the same market.
What did Kalshi say George Santos did?
Kalshi’s disciplinary notice, posted through its regulatory notice system, said Santos traded between February 2 and February 25, 2026 in a market tied to whether he would attend the State of the Union. The exchange said he then made public statements about his plans that affected prices in contracts linked to his own attendance.
The core allegation was not that Santos had merely expressed a view about a political event. Kalshi said the market’s underlying event was his own conduct, which placed him inside the exchange’s prohibition on trading contracts when a trader can influence the outcome. The exchange also said Santos made false or misleading statements about whether he would attend, then profited when the market moved in a direction favorable to his positions.
Kalshi calculated Santos’s profit at $17,839.57 and set the exchange penalty at $71,356, roughly four times that amount. The disciplinary notice also said Santos failed to cooperate with Kalshi’s compliance investigation. CBS News reported that a Kalshi spokesperson confirmed Santos was the first person to receive a lifetime ban from the platform.
How does the CFTC order compare with Kalshi’s action?
The CFTC’s July 31, 2026 press release and order settled federal charges against Santos for manipulative activity in an event contract whose underlying event he controlled. The CFTC said Santos traded a contract titled “Who will attend the State of the Union?” between February 12 and February 25, 2026, specifically on whether he would attend.
The federal order required Santos to disgorge $17,569.98 in profits and pay a $17,500 civil monetary penalty, for a total of $35,069.98. It also imposed a three-year trading ban and ordered him to cease and desist from further violations of the Commodity Exchange Act and CFTC regulations. The CFTC’s profit figure differs from Kalshi’s exchange-level profit calculation, but both actions concern the same State of the Union attendance market.
The CFTC said Santos made material misrepresentations and omissions in social media posts about whether he would attend the address. After those posts, the agency said, contract prices moved favorably for his positions and allowed him to make more than $17,500.
Why did the penalty become a lifetime ban?
Kalshi treated Santos differently from users who received temporary suspensions in other political-market enforcement matters. Robert DeNault, Kalshi’s head of enforcement, told reporters that Santos was the only person who did not cooperate with the investigation. Kalshi’s disciplinary notice tied the permanent bar to the exchange’s findings on prohibited trading, market manipulation and non-cooperation.
The distinction matters because Kalshi is a CFTC-regulated designated contract market, which means it has its own exchange rules and surveillance duties in addition to federal oversight by the agency. In this case, the federal regulator imposed disgorgement, a civil penalty and a three-year trading ban, while Kalshi imposed a separate platform penalty and lifetime exclusion from its exchange.
Kalshi has also disclosed other political-market discipline. In an April 22, 2026 enforcement update, DeNault said the exchange had brought three cases involving candidates who traded on their own races, including fines and multi-year suspensions. Later coverage of Kalshi disciplinary actions identified additional users who received temporary bans or fines, including Laurie Buckhout, Stephen Cloobeck and Ben Midgley. Santos’s case stands apart because the exchange made the sanction permanent.
How did Santos respond?
Santos rejected Kalshi’s action in public comments reported by Fortune and TIME. Fortune reported that he called Kalshi “an unserious company” and described the lifetime ban as “frivolous nonsense.” He also wrote on X, “thanks for the lifetime ban from your gambling platform,” according to Fortune.
TIME reported that Santos argued Kalshi had violated its own notice process by announcing the ban before the end of what he described as a 30-day notice window. His lawyer, Joseph Murray, separately said after the CFTC settlement that Santos resolved the federal matter to put it behind him and did not admit wrongdoing, according to the Associated Press account carried by The Washington Post.
Santos, a New York Republican, was expelled from the House in December 2023 after a House Ethics Committee investigation. The trading case drew attention because the contract did not involve a broad election or policy outcome. It asked whether Santos himself would attend a specific event, making his own conduct the market variable.
Why does this matter for prediction-market oversight?
The Santos case puts a concrete dollar amount on a core integrity risk for event-contract exchanges: a trader using private control over an outcome, or public statements about that outcome, to move prices. The CFTC order framed the issue as manipulative activity in a swap. Kalshi framed it as a violation of exchange rules against insider trading and manipulation.
That overlap is important for the industry. Federal regulators can bring enforcement actions under the Commodity Exchange Act, while a registered exchange such as Kalshi can discipline users under its own rulebook. The Santos matter shows those tracks can produce different sanctions from the same conduct: $35,069.98 and a three-year federal trading ban from the CFTC, plus a $71,356 Kalshi fine and a lifetime platform ban.
The case also gives regulators and market operators a specific benchmark for future political-event enforcement. Kalshi has said cooperation affected penalty outcomes in earlier political trading cases. Santos received the most severe exchange sanction after Kalshi said he traded on an event he controlled, made misleading public statements and did not cooperate with the investigation.
The next fixed marker is the duration of the federal ban. Under the CFTC’s July 31, 2026 order, Santos is barred from trading for three years, while Kalshi’s disciplinary action leaves him permanently barred from that exchange.
