In an unprecedented enforcement action, prediction market operator Kalshi has issued a lifetime prohibition against former Representative George Santos after uncovering a scheme where he manipulated contracts tied to his own attendance at President Donald Trump’s 2026 State of the Union speech.
The investigation revealed Santos generated $17,839.57 in profits by trading on contracts where he personally controlled the outcome. Platform regulations explicitly forbid participants from wagering on events they can directly influence.
Records show Santos established his Kalshi account on February 11, funding it with approximately $7,000. He devoted his entire balance to betting on his own attendance decision.
Social Media Deception Drives Price Swings
During the period spanning February 12 through 22, Santos accumulated 30,874 contracts predicting his attendance, investing $6,695.94. With this position secured, he published social media content soliciting opinions on whether to attend in formal attire or a flashy, embellished ensemble.
Market response was immediateāthe probability of his attendance surged from approximately $0.15 to $0.70 per contract. Santos capitalized on this spike by liquidating his entire stake, securing a $3,448.43 gain.
When his Washington-bound flight was subsequently canceled on February 22, Santos arranged train transportation. The following morning, he published messages implying severe weather conditions could thwart his travel plans. The attendance probability plummeted from $0.63 to $0.28.
By the evening of February 23, Santos released video content confirming his intention to view the address from the House gallery. Contract values rebounded from $0.40 to $0.70. Approximately forty minutes afterward, Santos reversed course and began acquiring contracts betting against his attendance, ultimately purchasing 23,855 for $8,650.66.
His train reservation was also canceled, yet he informed another platform user of his continued intention to attendādespite having secured no alternative transportation.
The Scheme Collapses
On February 24, Santos announced via social media that he was viewing the address on an airport television screen rather than attending in person. The attendance probability crashed from $0.73 to $0.02, dramatically boosting the value of his contrary position.
Santos liquidated his position against attendance on February 25, securing an additional $14,390.57 profit. This second windfall, combined with his initial trading gain, produced the total amount referenced in enforcement proceedings.
Kalshi levied a $71,356 fineāprecisely four times his ill-gotten gains. The lifetime prohibition blocks Santos from platform access whether attempted personally or through intermediaries.
Federal regulators at the Commodity Futures Trading Commission issued complementary sanctions on July 31. The CFTC order mandates Santos surrender $17,569.98 in disgorgement, pay a $17,500 civil monetary penalty, and accept a three-year exclusion from all federally registered trading facilities. Santos agreed to the settlement without acknowledging liability.
According to Kalshi, Santos refused to participate in the platform’s compliance investigation, a factor that elevated his punishment from temporary suspension to permanent expulsion.
The company disclosed it launched over 150 investigations during 2026’s first quarter, prevented more than 100 potential insider trading violations, and forwarded 20 matters to criminal authorities.
A Department of Justice investigation into Santos’s activities remains ongoing with no public announcement of its conclusion.
