Former US congressman George Santos to pay US$35,000 over unlawful Kalshi trades
Former US Congressman George Santos has agreed to pay US$35,000 to settle a federal investigation into trading activity on the prediction market platform Kalshi.
The settlement with the Commodity Futures Trading Commission (CFTC) follows allegations that Santos unlawfully traded on a Kalshi market over whether he would attend President Trump’s State of the Union address in February.
According to a CFTC press release, the settlement means Santos must forfeit over US$17,000 in profits from the trades, pay a civil penalty of $17,500 and accept a three-year ban from trading on the platform.
Santos posted a statement from his lawyer, Joseph Murray, on the social media platform X, saying that Santos agreed to the settlement to avoid lengthy litigation and did not admit to any wrongdoing.
The investigation was based on Santos’ trading activity before the State of the Union address. Although he had publicly said he planned to attend, he announced shortly after the speech began that he had been unable to travel. The market had assigned a high probability to his attendance, and his announcement led to scrutiny of his trading activity.
Kalshi reported the issue to regulators and said it would pursue its own enforcement action. The company also said it would try to reimburse affected traders if it recovers monetary penalties.
“The order finds that between February 12, 2026, and February 25, 2026, Santos traded a contract titled “Who will attend the State of the Union?” and more specifically, traded on whether he would attend the 2026 State of the Union or not,” the CFTC said in its statement.
“While buying and selling positions in this market, Santos posted on social media about his plans to attend or not attend the SOTU. In his social media posts, Santos made a series of material misrepresentations and omissions about whether he would attend the SOTU. After these posts, the SOTU contract prices moved in a direction that was favorable to Santos’ positions which allowed him to make over US$17,500,” it decreed.
Santos’ trades were featured in the recent Netflix documentary on prediction markets Instadocs: The Prediction Games, which premiered on 26 July.

The Backstory
Kalshi’s report put a political trade under federal scrutiny
The settlement with former U.S. Rep. George Santos grew out of a narrow but consequential question on Kalshi: whether Santos would attend President Donald Trump’s State of the Union address in February. The market itself was simple. The regulatory implications were not.
Santos had publicly suggested he would attend, helping shape expectations around a contract that moved as traders assessed the likelihood of his appearance. When he did not attend, and after his public statements diverged from the outcome, Kalshi flagged trading on his account as suspicious. The company’s referral to federal authorities moved the matter from platform surveillance into the orbit of the Commodity Futures Trading Commission and, according to earlier reporting, the Justice Department.
Complete iGaming previously reported that federal authorities were examining Santos’ Kalshi activity after the platform alerted regulators. At that stage, the central issue was whether Santos had traded against his own attendance while publicly indicating he expected to be there. Santos denied wrongdoing and said the accusation was “preposterous,” while also saying he would cooperate with any inquiry.
The CFTC’s order now converts that earlier scrutiny into an enforcement outcome. It does not require Santos to admit wrongdoing, but it forces disgorgement of profits, adds a civil penalty and removes him from Kalshi trading for three years. For a market built on public events, the case clarifies that regulators are willing to treat statements by a contract subject as potentially material to market pricing.
A test case for prediction market integrity
The Santos matter arrived as prediction markets were expanding from niche political and economic contracts into mass-market sports and entertainment products. That growth has lifted trading volumes, but it has also raised questions about market manipulation, privileged information and the line between federally regulated derivatives and gambling.
Kalshi’s role is central to the backstory. The company is a CFTC-regulated exchange, and its business model depends on presenting event contracts as financial instruments rather than wagers. That framing makes market integrity a core regulatory issue. If the subject of a contract can influence prices through public statements and trade around those movements, the product begins to resemble an information asymmetry problem familiar to securities and commodities regulators.
The Santos contract was not about a corporate earnings report or crop forecast. It was about a public official’s personal attendance at a political event. But the basic concern was similar: a trader with direct control over, or privileged knowledge of, the outcome may have an unfair advantage. The CFTC’s settlement signals that novelty in the underlying event does not exempt prediction markets from anti-manipulation principles.
Kalshi also had an incentive to act quickly. Its broader regulatory argument rests on the claim that federally supervised prediction markets can police themselves more effectively than offshore or unregulated alternatives. By reporting the activity and saying it would seek its own enforcement response, Kalshi positioned itself as a compliant exchange rather than a passive venue for disputed political trades.
Sports contracts accelerated the regulatory collision
The enforcement action against Santos comes against a larger fight over Kalshi’s expansion into sports-related event contracts. That business has grown rapidly, drawing customers who might otherwise use sportsbooks while provoking state regulators that view the products as unlicensed sports betting.
During March Madness, Kalshi reported a major surge in activity, with more than US$800 million traded on tournament-related contracts in the first weekend alone. The volume underscored the commercial potential of prediction markets at a time when U.S. sports betting remains regulated state by state. It also sharpened concerns from sports bodies, including the NCAA, about competition integrity and student-athlete safety.
The March Madness figures showed why the regulatory stakes are high. Prediction markets can resemble sportsbooks to consumers, especially when contracts are tied to game outcomes or tournament brackets. But the legal pathway is different. Kalshi argues that its contracts fall under federal commodities law, not state gambling statutes. State officials counter that sports outcomes offered to residents are gambling products regardless of the label.
That dispute matters for the Santos case because it places market integrity under a microscope. If prediction markets are to compete with gambling operators while claiming federal derivatives status, regulators must be able to demonstrate that they can detect and punish conduct that distorts prices. The Santos settlement gives the CFTC a concrete example of enforcement at the participant level, even as the broader jurisdictional fight continues.
States have challenged Kalshi’s federal shield
Several states have sought to block or restrict prediction markets, arguing that federal registration should not override local gambling laws. Kalshi and other operators have responded that they operate within a national derivatives framework and cannot be subjected to conflicting state-by-state rules.
Michigan has been one of the more visible battlegrounds. Complete iGaming reported that Michigan’s attorney general criticized the CFTC after it ordered Kalshi to honor pending trades from residents despite a temporary state-court block on sports event contracts. The CFTC argued that the Commodity Exchange Act requires federally registered exchanges to operate as a single national market and provide impartial access. Michigan said that position undermined its authority to regulate online sports betting and enforce state tax law.
Kentucky has pursued a similar line, with lawsuits and an excise tax aimed at prediction market operators. In response, the CFTC filed its own action, and Complete iGaming reported that the agency sued Kentucky over efforts to shut down federally regulated prediction markets. The state had described Kalshi and Polymarket as illegal sportsbooks. The CFTC said it was protecting its federal authority.
These cases reveal the industry’s unresolved legal architecture. Operators want federal recognition to provide nationwide scale. States want to preserve control over gambling policy, tax revenue and consumer protections. The Santos enforcement action does not settle that jurisdictional conflict, but it strengthens the CFTC’s claim that it is not merely defending industry expansion. It is also policing misconduct inside the markets it oversees.
Celebrity, politics and betting are converging
The Santos episode also reflects a wider convergence between public figures and betting-related platforms. Prediction markets thrive on recognizable events and personalities, while gambling operators increasingly rely on entertainment and political attention to attract users.
That trend is visible outside the U.S. as well. In the Philippines, Complete iGaming reported that actor Yen Santos signed as a Filbet brand ambassador, part of an effort by the online betting platform to reach audiences beyond traditional bettors. The campaign used celebrity visibility to pull entertainment fans into digital betting promotions, even as Philippine regulator PAGCOR pledged tighter restrictions on the country’s igaming industry.
The comparison is not direct: Yen Santos’ endorsement is commercial marketing, while George Santos’ case involved trading on an event tied to his own conduct. But both show how personal brands can shape gambling and prediction-market activity. When the person attached to an event can move audience behavior, platform engagement or market prices, regulators face harder questions about disclosure, influence and consumer protection.
For Kalshi, the immediate damage from the Santos case is limited by the settlement amount. The larger issue is reputational. The platform’s growth depends on trust that event contracts are not being distorted by insiders, public figures or subjects with unique control over outcomes. For the CFTC, the case offers a way to show that prediction markets can be regulated as financial venues without ignoring the risks that make them look, to many states, like gambling by another name.
