Former New York Congressman’s Kalshi Trading: Saying Yes While Buying No

The Kalshi CFTC settlement imposed a $17,500 civil penalty on a former New York congressman over allegations that he used public attendance posts to benefit his trades on whether he would attend the State of the Union. The order separately required him to surrender $17,570 in trading profits. For someone who understands the account activity or the travel arrangements, the revealing detail is the sequence the Commission describes: what he told the market, what he knew about getting there, and which position he held when he spoke.

The Commodity Futures Trading Commission’s July 31, 2026 consent order covered trading from February 12 through February 25, 2026. KalshiEX LLC operated the market on his attendance at that year’s State of the Union. The CFTC enforcement action concerned the trader’s conduct, with Kalshi as the venue.

The Yes Position and the Clothing Post

According to the order, the former congressman first bought Yes contracts on his attendance on February 12, the same day he bought a plane ticket to Washington for the event. The order says he had opened his Kalshi account the previous day and traded only in the market on his own attendance.

The order says that by February 22, he had accumulated 30,874 Yes contracts. Early that morning, he posted on X asking whether to wear a muted or serious suit or a bedazzled one. The order says the Yes price rose several hours later, and he sold the entire position for a profit of $3,448.

The question about clothing carried an assumption: he would be there to wear it. The Commission connected that public suggestion of attendance to a position that gained value as attendance became more likely in the market’s pricing. He could profit by selling the contracts before the event took place.

The order also follows the withdrawal from Kalshi to a recently opened Venmo account registered to the same phone number. Later that day, the airline notified him that his flight had been canceled. He bought a train ticket that night, but the Commission said he did not publicly disclose either the flight cancellation or his exit from the Yes position.

The Commission describes different records of the same day: the public post, the closed position, the withdrawal and the canceled flight. Read together, its account connects what the market heard with what changed behind the public account of his plans.

The Attendance Video and the Move to No

The order describes a reversal on February 23: public assurances of attendance followed by purchases of No contracts. Earlier that morning, he had complained on X about travel difficulties and suggested the weather might prevent the State of the Union itself from taking place. The Yes price fell after that post.

The order says he later assured his audience he would attend. At approximately 5:18 p.m. Eastern, his video included this statement:

The order says the Yes price rose shortly after the video. According to the Commission, at approximately 5:59 p.m., he began building the opposite position, buying contracts that would benefit from his absence. He ultimately accumulated 23,855 No contracts.

The order says the train service canceled his reservation that evening. He later answered another X user’s question about whether he was actually going with “I am”. According to the Commission, he did not publicly disclose that both his flight and train had been canceled.

As the Commission tells it, he was buying contracts that paid for his absence after publicly promising to attend. We would call that betting against your own promise. The canceled train adds the detail a price chart cannot supply: what the Commission says the trader knew when he repeated the assurance.

The Airport Post and the Exit

On February 24, the day of the State of the Union, the order says he posted about watching from an airport after both travel reservations had been canceled. It also says he had bought no additional tickets to Washington that day. That evening, his X post read:

The Yes price fell sharply after the post, making his No position highly profitable, according to the order. The order says he exited that position in the early hours of February 25 for a profit of $14,391. In the Commission’s account, the market heard him announce attendance and then absence, while his trading moved from one side of that question to the other.

Why the CFTC Treated the Posts as Market Manipulation

The Commission’s market manipulation order connected what it called misleading statements and omissions to the benefit for his trading positions. The order said he could influence the underlying event, his own attendance, and used public statements about it to influence the contract price. In that account, the person whose behavior the market was trying to predict was also trading that prediction.

The order treated the attendance contract as a swap, a financial contract within the CFTC’s authority. Its value depended on whether a specified future event occurred: his attendance.

The June 2024 working paper An Analysis of Market Manipulation Definitions Around the World, from a World Federation of Exchanges research project, separates several mechanisms. False information can alter how people value an instrument. Actions can affect an asset’s actual or perceived price, while trading itself can also be used to move prices.

That distinction helps explain why the messages belong beside the account history. Here, the Commission’s account links the public information, the trader’s influence over attendance and the positions that benefited. Looking only at purchases and sales leaves out the statements the Commission identified as part of the conduct.

What Is the Penalty for Market Manipulation?

Here, the CFTC ordered a civil fine, the surrender of trading profits and a three-year ban on trading directly or indirectly on registered markets or under their rules. The fine itself was smaller than the profits the order required him to hand back. The order also required him to stop the manipulative or deceptive conduct it prohibited.

How the Posts, Trades and Canceled Tickets Fit Together

In the attendance-trading case, the evidence described by the CFTC connects the account’s positions to public statements and facts the trader knew privately. The order gives the timing of the posts, purchases, sales and travel cancellations. Those records let the reader see what the market heard while the account changed direction.

In the order’s account, the trading history shows which result would benefit the trader, while the posts show what he told other participants. The cancellation records supply travel information the Commission said he withheld, and the withdrawal to Venmo follows money out of the account.

The order identifies Kalshi as a designated contract market, a CFTC-regulated exchange for event contracts. For its surveillance staff, detecting and investigating possible violations is part of the exchange’s continuing duty to enforce its rules. An insider who can connect a flagged trade to a misleading message supplies a piece of that investigation.

The World Federation of Exchanges working paper describes surveillance systems flagging unusual trading patterns for analysts to investigate. It also describes detection through financial intermediaries, public reports and whistleblowers, and the need to examine communications including social media.

For an insider, knowing what a message meant can be as useful as knowing when it appeared. Someone familiar with travel arrangements may understand the undisclosed cancellation, while a surveillance analyst may understand the position that gained from the later announcement. Our work starts with the connection you can explain between those facts.

Confidential Speech Information Presents a Different Trading Advantage

In a separate August 28, 2026 consent order, the CFTC addressed a federal technical advisor’s alleged use of confidential presidential speech information in event-contract trading. That case concerned information obtained through government work. The attendance case concerned a trader’s public statements and omissions about an event he could influence himself.

The distinction matters to the person who knows the source of the advantage. Access to confidential speech material explains one trading story. Knowledge of canceled travel and control over personal attendance explain another.

What a CFTC Whistleblower Brings to a Case Like This

The CFTC whistleblower program can award 10% to 30% of qualifying sanctions actually collected. An ordinary covered CFTC action must impose more than $1 million in sanctions. We help you build the connection between what you know, the trading it explains and a potential CFTC whistleblower award.

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers. That separate law concerns fraud against the government. For the market insider who can explain a misleading post or a concealed trading advantage, our focus here is the CFTC program.

You Know What Was Behind the Post

If you can connect a public statement to the position that benefited and the facts kept out of view, tell our whistleblower experts what you saw. We develop the trading story with you and bring in CFTC whistleblower lawyers who understand how communications and account activity fit together. We stay beside you as that inside knowledge becomes the foundation of your case.
