Connecticut Federal Court Denies Kalshi's PI — With a Novel Argument: Sports Event Contracts Are Not 'Swaps' at All
The U.S. District Court for the District of Connecticut has denied Kalshi's request for a preliminary injunction, allowing the state to enforce its gambling laws against prediction market sports contracts. Judge Vernon D. Oliver ruled that Kalshi's sports-event contracts do not satisfy the statutory definition of a 'swap' under the Commodity Exchange Act — because they depend on event outcomes, not on whether an event occurs. Kalshi has appealed to the Second Circuit, giving that court two simultaneous Kalshi appeals. Gaming law attorney Daniel Wallach says both Second Circuit cases could be consolidated for oral argument. The ruling creates a direct circuit conflict with a Third Circuit ruling from April that found Kalshi's contracts ARE swaps.
Judge Vernon D. Oliver of the U.S. District Court for the District of Connecticut has denied Kalshi's motion for a preliminary injunction, allowing Connecticut's Department of Consumer Protection to enforce state gambling laws against Kalshi's sports-event contracts. The ruling is the fifth judicial decision to go against Kalshi on PI motions in 2026, joining Michigan, Nevada, New York, and Washington — but it introduces a statutory interpretation argument that none of the other rulings relied on. Judge Oliver found that Kalshi's sports contracts do not satisfy the Commodity Exchange Act's definition of a 'swap' in the first place: 'Kalshi's sports-event contracts fail to satisfy this portion of the statutory definition of a swap because they do not depend on whether an underlying sporting event occurs, fails to occur, or occurs to a particular extent. Instead, Kalshi's sports-event contracts depend on the event's outcomes or discrete in-game occurrences.' The distinction is narrow but legally significant: a contract that pays out if a team wins is not the same as a contract that pays out if a game is played. The CEA definition of a swap, Oliver concluded, covers the latter but not the former — which would mean Kalshi's contracts are outside federal derivatives jurisdiction structurally, not just because of preemption doctrine.
The ruling creates a direct circuit conflict. In April, the Third Circuit ruled that Kalshi's sports event contracts ARE swaps under the CEA — the opposite conclusion on the same statutory question. A circuit split on whether prediction market sports contracts meet the CEA definition of a swap is the clearest possible pathway to Supreme Court review, since the resolution of the same federal statutory question cannot differ by geography. Gaming law and sports betting attorney Daniel Wallach noted that Kalshi is now involved in two separate Second Circuit appeals — the New York case from July 7, where Judge Analisa Torres also denied Kalshi's PI and ruled the CEA does not preempt New York gambling law, and the Connecticut case appealed this week. Wallach said both Second Circuit cases could be combined for purposes of oral argument, which would produce a single authoritative ruling on multiple grounds simultaneously. Traders on prediction market platforms are already pricing a 64% probability of Supreme Court review by the end of 2026.
The Connecticut background adds detail to the legal record. The state's Department of Consumer Protection Gaming Division issued cease-and-desist notices to Kalshi, Robinhood, and Crypto.com on December 2 for alleged unlicensed sports wagering — the same day that Polymarket's US platform (Polymarket QCEX) launched. Kalshi filed suit the following day, arguing its event contracts fall under CFTC oversight as a designated contract market licensee. Judge Oliver's ruling rejects that argument on two grounds: the contracts do not satisfy the CEA definition of a swap, and Congress did not displace Connecticut's authority to regulate sports betting. Oliver also pointed to Kalshi's own marketing, which described the platform as offering 'legal sports betting nationwide' despite sports wagering being traditionally regulated at the state level — citing Kalshi's own language as evidence that the products functioned as wagering regardless of their formal regulatory classification. A Kalshi spokesperson said the company 'disagrees with the Court's decision.'
The scale of state resistance has grown well beyond the eleven states in active litigation. At least 34 states and territories have filed amicus briefs backing state control over sports-event contracts, reflecting a broad political consensus that federal recognition of such contracts as swaps would significantly weaken local gambling regulation frameworks. The Connecticut ruling, combined with the existing losses in Michigan, Nevada, New York, and Washington, means Kalshi has now lost PI motions in all five jurisdictions where federal judges have ruled on the merits, with the sole win coming from Arizona in May — where Judge Liburdi applied a three-prong preemption analysis that no other court has followed. The NFL season begins in September, the CFTC's comment window on its proposed NPRM closed July 27, and the August 12 Michigan geofencing deadline arrives tomorrow. Against that backdrop, the Connecticut ruling adds a new and potentially more durable legal theory — the swap-definition argument — to the arsenal of states seeking to block prediction market sports contracts without relying solely on preemption doctrine.

Baltimore Sues Kalshi and Polymarket for Unlicensed Sports Betting — First Municipal Lawsuit Against Prediction Markets
The City of Baltimore has filed suit against Kalshi and Polymarket, alleging they operate unlicensed sports betting that allows them to compete with regulated sportsbooks while avoiding state oversight, taxation, and responsible-gambling requirements. Baltimore is the first municipality — rather than a state — to pursue legal action against prediction market platforms. The suit arrives as DraftKings and FanDuel reported weak sportsbook earnings and pivoted toward prediction markets, and as the gap between prediction markets' 18-year-old minimum age and Maryland's 21+ sports betting requirement draws regulatory attention.
Harry Kane Is the 41% Favorite for the 2026 Ballon d'Or on Polymarket — Lamine Yamal Surges After World Cup
Prediction markets have installed Harry Kane as the heavy favorite for the 2026 Ballon d'Or, with Polymarket pricing him at 41% and Kalshi near 42% — both reflecting his record-breaking 2025-26 season at Bayern Munich, where he scored 73 goals and won the Bundesliga and DFB-Pokal double. Lamine Yamal has surged to 26-35% on Kalshi following Spain's World Cup victory, up from around 4% before the tournament. The award ceremony takes place October 26 in London.
Kalshi's Double Geofencing Deadline Passes as NFL Preseason Begins — Michigan and Nevada Both Required GeoComply by August 12
August 12 was simultaneously the geofencing deadline in Michigan ($500,000/day fine) and Nevada ($120,000/day fine) — and the first week of the 2026 NFL preseason. Kalshi had until that date to implement GeoComply's commercial multi-source geolocation system in both states, blocking residents from accessing sports event contracts. The dual deadline arrives as prediction market platforms report explosive NFL-season growth: Kalshi already has over $59 million in Super Bowl LXI trading volume and more than 100,000 app downloads in the past month.
