George Santos Permanently Banned from Prediction Market Kalshi Over Insider Trading Allegations
Prediction-market exchange Kalshi has issued a lifetime ban to former U.S. Representative George Santos, citing findings by its Compliance Department that there was “reasonable cause to believe” he engaged in insider trading and market manipulation. The ban, effective August 28, 2026, marks the first permanent penalty of its kind for the platform.
Allegations of Trading on Personal Influence
According to an official compliance document, Santos traded on markets related to his attendance at the State of the Union address on February 24. He was reportedly prohibited from participating in these markets due to his potential to influence the underlying event’s outcome. Kalshi stated that Santos executed a series of substantial trades between February 2 and February 25 in contracts whose results hinged on his personal presence.
The exchange claims Santos profited significantly from this activity, earning $17,839.57 from the targeted markets. In addition to the permanent suspension of his access, both direct and indirect, Kalshi’s Compliance Department has levied a penalty of $71,356 against him.
Santos Denounces Kalshi’s Actions
In response to the ban, Santos took to the social media platform X (formerly Twitter) to criticize Kalshi, accusing the exchange of violating its own stated notices and deadlines. He asserted that a notice received on August 7 had granted his side 30 days before any further action, questioning why Kalshi had announced what he termed “frivolous nonsense” before that period had elapsed. Santos further characterized the organization’s approach as “pathetic!” and suggested that “leaking and attention seeking seem to be the M/O of this organization.”
Broader Regulatory Landscape and Legal Challenges
This development follows a settlement Santos reached last month with the Commodity Futures Trading Commission (CFTC), which asserts jurisdiction over prediction markets. Under that agreement, Santos consented to pay $35,000 without admitting or denying the agency’s findings. His counsel, Joseph W. Murray, stated that Santos had cooperated with the CFTC.
Santos, who was expelled from the House of Representatives in 2023 amid federal charges, was sentenced in April 2025 to over seven years in prison after pleading guilty to wire fraud and identity theft. His sentence was commuted by then-President Trump in October of that year, leading to his release after serving less than three months.
Kalshi has previously suspended three U.S. political candidates for betting on election outcomes in which they were directly involved, labeling such actions as “political insider trading.”
Prediction-market platforms are currently facing increased scrutiny from regulators and lawmakers. Last month, Baltimore city officials filed a lawsuit against Kalshi and Polymarket, alleging that their sports prediction contracts constitute unlicensed sports betting and could mislead consumers regarding their legal and regulatory standing.
Separately, Kalshi is engaged in litigation with New York Attorney General Letitia James. The exchange also faced a lawsuit from FlightAware concerning flight-related markets, though that case was withdrawn shortly after its initiation.
