Kalshi Bans House Candidate Laurie Buckhout for Three Years Over Self-Bet

Kalshi is a U.S. event-contract exchange regulated by the Commodity Futures Trading Commission, where users trade on outcomes ranging from politics to economics. Former Republican Representative George Santos could directly determine whether he attended President Donald Trump’s 2026 State of the Union, making his trades on that outcome a test of rules barring participants with influence over an event. The case highlights insider-trading and manipulation risks as prediction markets expand and face closer regulatory scrutiny.

Kalshi said on Aug. 31 that its Compliance Department had reasonable cause to believe Santos used false or misleading public statements to move prices while trading contracts tied to his attendance at the Feb. 24 address. Santos earned $17,839, according to the company. The lifetime ban took effect Aug. 28, blocks direct and indirect access, and carries a $71,356 penalty, Kalshi’s first permanent suspension. Separately, Santos settled a CFTC case in July for about $35,000, including disgorgement and a civil fine.

Kalshi is a CFTC-registered designated contract market that lets users trade event contracts tied to sports, elections and other outcomes. Its legal strategy rests on federal pre-emption: the company argues the Commodity Exchange Act gives the Commodity Futures Trading Commission exclusive authority over its exchange, while states contend much of the activity is gambling subject to local licensing and consumer-protection laws. The outcome will determine whether prediction markets can operate under one national framework or face a state-by-state patchwork.

On Aug. 13, King County Superior Court Judge John McHale ordered Kalshi to block Washington users from most contracts, requiring initial IP and residency geofencing by Aug. 19 and a multi-source system by Sept. 2. Kalshi sought reconsideration on Aug. 20, citing Washington’s decision not to enforce equivalent restrictions against Crypto.com pending appeal. Separately, 44 state attorneys general challenged the CFTC’s 267-page proposed rule after comments closed July 27. The CFTC invoked emergency authority on Aug. 11 to keep Kalshi operating amid New York’s July 31 suit, which seeks more than $36 billion in damages.

Kalshi, designated as a contract market by the Commodity Futures Trading Commission in 2020, lets users trade contracts tied to outcomes ranging from sports and elections to economic data. Washington state argues those products amount to unlicensed gambling, while Kalshi says federal derivatives law gives the CFTC exclusive authority. The dispute is important because its outcome could determine whether state gambling rules can constrain a fast-growing industry built around federally regulated event contracts.

King County Superior Court Judge John McHale on Aug. 13 ordered Kalshi to stop accepting new positions in most markets by Aug. 19 and implement geofencing by Sept. 2. Noncompliance could trigger penalties of $120,000 a day. The order allows trading tied to commodities, climate, economics and finance to continue, while restricting categories including sports. Washington Attorney General Nick Brown filed the underlying lawsuit on March 27, accusing Kalshi of violating the state Gambling Act and Consumer Protection Act.

Prediction markets let traders buy event contracts tied to elections, economic data, sports and other outcomes. Supporters say the products improve price discovery and offer a more precise hedge against discrete risks, while critics argue they amount to gambling under a financial label. The sector accelerated after a 2024 federal court ruling cleared Kalshi to list political contracts, intensifying disputes between the Commodity Futures Trading Commission and state authorities over jurisdiction, market integrity, insider trading and consumer safeguards.

A recent Council on Foreign Relations symposium examined whether prediction markets serve the public interest and how they could affect the financial system. JPMorgan Chase is studying a possible entry, while Goldman Sachs CEO David Solomon has called event-contract activity “super interesting.” As of May 27, 2026, Kalshi said annualized trading volume had reached $178 billion and institutional volume had risen 800% in six months. Former acting CFPB director Mick Mulvaney said legislation was unlikely to clear Congress soon, leaving courts to shape the regulatory framework.

Prediction markets translate prices on real-money event contracts into continuously updated probabilities, offering campaigns and voters a market-based complement to conventional polling. The stakes are high in the Nov. 3, 2026, midterm elections: all 435 House seats and about one-third of the Senate will be contested, with control of Congress set to shape President Donald Trump’s legislative agenda. Kalshi raised $1 billion at a $22 billion valuation in May, underscoring the sector’s rapid expansion.

Kalshi launched its Midterms Hub on July 21, combining live markets for House, Senate and gubernatorial races with VoteHub polling averages, Federal Election Commission fundraising data, historical results and campaign news. At launch, its contracts assigned Republicans a 56% chance of retaining the Senate and Democrats an 83% chance of winning the House. Kalshi said about 75% of visitors use the platform to follow forecasts rather than trade, while candidates favored by its markets have won about 90% of U.S. races since 2024.

Kalshi is a prediction market regulated by the U.S. Commodity Futures Trading Commission that allows users to trade contracts on event outcomes. The company argues that its products are financial swaps, while Michigan considers its sports contracts to be unlicensed online gambling. The dispute centers on whether federal financial regulation can preempt state gambling laws and also raises questions about consumer protection and gambling tax revenue.

On June 29, 2026, Ingham County Circuit Court Judge Rosemarie Aquilina granted Michigan Attorney General Dana Nessel's request for a 14-day temporary restraining order barring Kalshi from offering or promoting sports contracts to people in the state. The platform must use third-party geolocation technology that complies with state rules to block users. Violations carry a fine of $120,000 per day, and the order was originally set to remain in effect through July 13.

Kalshi is a prediction-market platform regulated by the U.S. Commodity Futures Trading Commission (CFTC) that allows users to trade contracts based on sporting-event outcomes. Illinois has subjected such products to state sports-betting restrictions, sparking a dispute over whether federal derivatives oversight preempts state intervention. The outcome could also affect how prediction markets operate across states.

Kalshi recently sued Illinois officials to challenge a provision in the state's newly enacted budget bill that is scheduled to take effect on July 1. The company argues that restrictions on sporting-event contracts encroach on the CFTC's exclusive regulatory authority. It is seeking to block enforcement, saying the provision would immediately restrict its products and cause irreparable harm that monetary damages could not adequately remedy.

Kalshi is a Commodity Futures Trading Commission-regulated designated contract market where users trade on the outcomes of elections, entertainment events and other events. As the market expands rapidly, traders with nonpublic information could distort prices and undermine trust. The platform therefore established an independent surveillance and audit committee in February 2026 and publicly disclosed enforcement actions for the first time, setting an insider-trading enforcement precedent for prediction markets.

On February 25, 2026, Kalshi found that MrBeast editor Artem Kaptur had used nonpublic information to trade and earned more than $5,000. It fined him $20,397.58 and banned him for two years. On April 22, it also penalized Mark Moran and two other candidates who bet on their own election prospects, banning each for five years and imposing fines of up to about $6,200. Starting June 10, users trading in high-risk markets must disclose their employers.

Kalshi is a prediction market platform regulated by the U.S. Commodity Futures Trading Commission (CFTC), allowing users to trade contracts tied to political, economic and other events. Traditional gambling operators are largely regulated by state governments, creating conflicts over regulatory authority and market access. Federal legislation would shape the industry's competitive landscape.

Kalshi recently announced its support for the newly formed Americans for Fair Markets (AFM), which argues that prediction markets should be regulated exclusively by the CFTC. It also backs the Gillibrand–McCormick bill to establish a federal legal framework. Available information does not provide the dates of the group's formation or Kalshi's announcement, and no investment or fundraising amounts were disclosed.

Kalshi is an event-contract exchange regulated by the U.S. Commodity Futures Trading Commission (CFTC), with markets covering elections and economic data. Traditional prediction markets require positions to be fully collateralized, limiting capital efficiency. The company raised $1 billion at an $11 billion valuation on December 2, 2025, making expansion into the institutional market a key driver of growth.

A National Futures Association (NFA) filing dated March 24, 2026, shows that Kalshi affiliate Kinetic Markets LLC has been approved to register as a futures commission merchant (FCM). The license will allow the platform to initially offer margin trading to institutional investors, enabling them to establish positions with less upfront capital. Chief Executive Tarek Mansour said the product would launch soon but did not disclose a launch date or leverage ratio.
