Kalshi Scores Temporary Win Against Connecticut Gambling Order

Prediction market platform Kalshi has notched a preliminary legal victory, with a federal judge granting a temporary injunction that halts Connecticut’s enforcement of a cease-and-desist order accusing the company of unlicensed sports wagering. Issued on December 9, 2025, by U.S. District Judge Vernon Oliver, the ruling allows Kalshi to keep offering event contracts to Connecticut users while litigation unfolds, underscoring the clash between federal derivatives oversight and state gambling statutes.

On December 2, the Connecticut Department of Consumer Protection (DCP) Gaming Division fired off cease-and-desist letters to Kalshi, Robinhood Derivatives, and Crypto.com, deeming their sports event contracts—such as NFL outcomes or weather props—as illegal online gambling under state law SB 146. The DCP demanded an immediate halt to offerings, promotions, and fund withdrawals for residents, threatening civil and criminal penalties.
Kalshi swiftly countersued in Connecticut federal court on December 3, asserting that its CFTC-regulated swaps fall under the Commodity Exchange Act (CEA), preempting state intervention. The platform sought an emergency temporary restraining order and preliminary injunction, arguing the order stifles lawful financial innovation. While Crypto.com and Robinhood paused operations, Kalshi pressed on, citing similar wins in New Jersey and Nevada.
Judge Oliver’s order mandates the DCP to “refrain from taking enforcement action” against Kalshi pending resolution. The state must respond by January 9, 2026; Kalshi by January 30; with oral arguments slated for mid-February.

1. Operational Continuity: Users in Connecticut retain access to Kalshi’s markets, from political elections to cultural events, preserving trading volume in the ninth state to challenge the platform.
2. Precedent Potential: A favorable full ruling could shield prediction markets nationwide, emboldening rivals like FanDuel and DraftKings amid their own launches.
3. Lingering Uncertainty: This is interim relief only; broader questions on gambling vs. derivatives persist, mirroring battles in Massachusetts and New York.

As a CFTC-designated contract market since 2021, Kalshi insists its binary options on real-world events are hedging tools, not bets, protected by federal exclusivity. CEO Tarek Mansour hailed the injunction as validation for “democratizing markets,” vowing to push for uniform guidelines as volumes surge post-2024 election.

Kalshi’s injunction buys time in a regulatory patchwork, highlighting fintech’s uphill fight against antiquated gambling laws. As courts deliberate, this saga could redefine event trading’s legitimacy, fostering innovation or fragmentation. For users, it’s a green light—for now—but diversification beyond state lines remains prudent.
