Michigan Judge Orders Kalshi to Keep Sports Markets Blocked

Kalshi operates a designated contract market regulated by the Commodity Futures Trading Commission and argues that its event contracts are federally supervised derivatives rather than wagers subject to state licensing. The dispute tests where financial regulation ends and gambling oversight begins, with major implications for prediction-market operators, state consumer-protection regimes and the CFTC’s claim to exclusive jurisdiction under the Commodity Exchange Act.

On Aug. 28, 2026, a unanimous three-judge panel of the U.S. Court of Appeals for the Ninth Circuit held that Kalshi had not shown the Commodity Exchange Act was likely to preempt Nevada gaming laws. The court affirmed the dissolution of an injunction covering sports-event contracts and sent questions involving election contracts back to the district court. No monetary damages were awarded. The decision conflicts with the Third Circuit’s approach, prompting the CFTC to signal a potential Supreme Court fight.

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.

Kalshi lets users trade event contracts tied to sports, elections and other outcomes, arguing that its status as a designated contract market overseen by the U.S. Commodity Futures Trading Commission puts it under federal commodities law rather than state gambling regimes. The stakes extend across the fast-growing prediction-market industry: Kalshi recorded $33 billion in volume in June 2026, compared with a combined $13.95 billion for Polymarket and its U.S. platform.

King County Superior Court Judge John McHale on July 20, 2026, granted the Washington Attorney General’s Office a preliminary injunction, finding the state was likely to prove Kalshi violated the Washington Gambling Act and Consumer Protection Act. He also rejected Kalshi’s argument that the federal Commodity Exchange Act preempts state law. The court will review further submissions by Aug. 3, with the order set to take effect no earlier than Aug. 5 and temporarily bar sports-related event contracts in Washington.

The dispute between the Commodity Futures Trading Commission and prediction-market platform Kalshi stems from a Michigan court’s June 29, 2026, finding that Kalshi’s contracts allegedly constituted illegal gambling and its order to cancel completed trades. The case centers on a clash between federal regulatory authority and state law. The CFTC warned that canceling trades would seriously undermine market confidence and contractual certainty.

In the latest development, the CFTC said on July 14, 2026, U.S. Eastern Time that it had invoked emergency powers to stop Kalshi from proceeding with plans to cancel trades by Michigan users, ordering the platform to settle them under normal procedures. Meanwhile, the Michigan court extended its injunction against the platform’s sports-event contracts and ordered Kalshi to implement geofencing to block users in the state by August 12, 2026, or face daily fines.

Kalshi is a Commodity Futures Trading Commission-regulated designated contract market where users trade yes-or-no event contracts that settle at a maximum of $1. The New York State Gaming Commission argues that sports contracts constitute gambling subject to state law. The dispute centers on whether the federal Commodity Exchange Act preempts state enforcement and could also affect the platform’s cost of operating across state lines.

On July 7, 2026, U.S. District Judge Analisa Torres of the Southern District of New York denied Kalshi’s motion for a preliminary injunction. She found that the company had not sufficiently shown that federal law preempted New York’s gambling laws and that the associated compliance costs did not constitute irreparable harm. Kalshi filed a notice of appeal the same day, and the case entered the U.S. Court of Appeals for the Second Circuit on July 8 under docket number 26-1835.

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 designated contract market regulated by the US Commodity Futures Trading Commission, allowing users to trade event contracts tied to outcomes including sports results. Each contract settles at a maximum of $1. New Jersey's Division of Gaming Enforcement classified the activity as unlicensed sports betting, raising the question of whether federal derivatives regulation preempts state law.

On April 6, 2026, the US Court of Appeals for the Third Circuit voted 2–1 to uphold a preliminary injunction issued on April 28, 2025. The court found that sports event contracts are swaps under the Commodity Exchange Act and fall under the CFTC's exclusive jurisdiction. On June 26, the state separately requested an extension until September 4 to file a petition for a writ of certiorari with the Supreme Court.

Kalshi, an event-contract exchange founded in 2018 and launched in 2021, lets users wager on real-world events through “yes/no” contracts. It expanded into politics in 2024 and sports in 2025. The dispute centers on whether the federal Commodity Exchange Act preempts state gambling laws, with implications for the regulatory boundaries of prediction markets across the United States.

Washington Attorney General Nicholas Brown sued Kalshi in King County Superior Court on March 27, 2026, alleging that it offered wagering on elections, sports and judicial events without a license from the Washington State Gambling Commission. Contracts cost $0.01–$0.99 each and pay the winner $1. The state is seeking a permanent injunction, restitution for all losses incurred by residents, disgorgement of proceeds and penalties for each violation. The complaint did not specify a total amount.
