Washington Judge Expands Kalshi Injunction — Sports, Elections, Politics, Entertainment and 'Mentions' Markets Must All Stop by September 2
King County Superior Court has issued a detailed compliance order requiring Kalshi to geofence sports, elections, politics, entertainment, culture, tech/science, and 'mentions' markets from Washington residents by September 2. Financial, commodities, climate, and economics markets survive. The Washington Court of Appeals denied Kalshi's stay request. The NFL season starts September 4 — two days after the compliance deadline.
King County Superior Court Judge John McHale has issued a final compliance order in Washington state requiring Kalshi to block residents from accessing sports, elections, politics, entertainment, culture, tech and science, and 'mentions' contracts. Commodities, climate, economics, and finance markets are explicitly exempted. The geofencing schedule is phased: IP-based blocking by August 19, multi-source commercial geolocation by September 2. Non-compliance triggers $120,000-per-day fines. The Washington Court of Appeals denied Kalshi's emergency application to stay the injunction pending appeal, meaning Kalshi must comply on schedule regardless of the appeal's outcome.
For UK readers, two elements of the Washington order merit attention. First, the 'mentions' category: Kalshi's mentions markets let traders bet on whether a named public figure — a politician, CEO, or celebrity — will use a specific word or phrase in an unscripted context. Washington state's gambling law defines gambling as staking something of value on the outcome of a future event determined partly or wholly by chance, and the state's position is that unprompted speech satisfies that definition. This is a product type the UK Gambling Commission has not explicitly addressed, but the analytical framework is identical: a binary outcome tied to a human choice in real time is closer to a wager than a financial instrument. Second, the financial-markets carve-out: Washington explicitly allows Kalshi to continue commodities, climate, economics, and finance contracts. That carve-out maps to the distinction between event-outcome contracts (sports, politics, mentions) and data-referenced contracts (commodity prices, economic statistics) — the same line Judge Oliver drew in Connecticut's August 11 ruling.
The compliance timeline sits directly against the NFL season. The September 2 multi-source geofencing deadline falls two days before the 2026 NFL regular season begins on September 4. Kalshi's sports event contracts in Washington must be geofenced before the first regular-season game. This is the highest-stakes compliance test the platform has faced: the NFL season is the primary commercial growth catalyst every prediction market platform has cited for 2026, and Washington — with Seattle as a major market — is one of the larger states Kalshi operates in. Kalshi now has concurrent geofencing obligations in Michigan, Nevada, and Washington, each requiring commercial-grade multi-source geolocation (GeoComply in Michigan and Nevada, a vendor TBD in Washington by September 2) — all operational before the NFL season's first full weekend.
The Court of Appeals' refusal to stay the injunction is operationally decisive. Kalshi had sought a stay that would have allowed it to keep offering sports markets in Washington through the duration of its appeal — potentially through the entire NFL season. The denial forecloses that option. The appeal itself continues, and Kalshi's CFTC preemption arguments remain alive in the appellate record, but Washington residents will not have access to Kalshi sports markets during the season regardless of how the appeal resolves. The detailed product-category list in Judge McHale's compliance order — sports, elections, politics, entertainment, culture, tech/science, mentions on one side; commodities, climate, economics, finance on the other — is the most granular template any state court has produced and gives courts in other jurisdictions a concrete model for their own compliance frameworks.

Utah Files Felony Charges Against Kalshi and Its Founders — Second State to Criminally Charge a Platform
Utah filed criminal charges against Kalshi and its two co-founders, Tarek Mansour and Luana Lopes Lara, on October 28 — 13 felonies and a misdemeanour, including a second-degree 'pattern of unlawful criminal activity' count and 12 counts of online gambling promotion. The charges stem from a September sting in which an undercover agent placed 12 sports wagers verified to be in Utah. The CFTC sued Utah the day before to block state enforcement, its tenth such suit. Utah is the second state after Arizona to criminally charge Kalshi, and the first to charge the founders personally. Kalshi called it a 'crazy overreach.'
NBA Names Kalshi and Polymarket Preferred Exchanges — Leaving the NFL Alone in Opposition
The NBA announced on October 26 that it has named Kalshi and Polymarket its 'preferred prediction market exchanges,' signed a non-binding memorandum of understanding with the CFTC on basketball integrity, and expanded its DraftKings deal to include prediction markets — the first league to extend a sportsbook partnership into the category. The exchange deals bar league and team personnel from trading NBA contracts, limit permissible markets, and require sharing suspicious-trading data, in exchange for NBA intellectual property and official data. The NBA joins MLB, the NHL, and MLS as partnered leagues, leaving the NFL as the lone major holdout — and the only league fighting the platforms in court.
CFTC Chair Says Agency Is Watching Prediction Markets for Manipulation Ahead of Midterms
CFTC Chairman Michael Selig said on October 23 that the agency is closely monitoring prediction markets for manipulation ahead of the November 3 midterms, and that it is separately scrutinising oil market trading tied to President Trump's announcements about the war in Iran. Combined midterm open interest on Kalshi and Polymarket stood at $250 million as of October 18, with Kalshi holding 84%. Selig acknowledged the agency often catches political figures trading 'oftentimes after the fact.' The remarks highlight the CFTC's dual role as both the platforms' federal protector and their manipulation watchdog.
