Connecticut Files Lawsuit Against Kalshi Over Alleged Unlicensed Sports Wagers

Connecticut has launched legal proceedings against Kalshi, accusing the federally regulated prediction markets operator of offering unlicensed sports wagers in the state. The legal complaint was filed by Attorney General William Tong, Department of Consumer Protection Commissioner Bryan T Cafferelli, and Governor Ned Lamont, seeking an immediate injunction to stop Kalshi from providing sports betting products in Connecticut. State officials allege Kalshi's sports event contracts are virtually indistinguishable from conventional sports betting—a category tightly regulated since Connecticut legalized the activity in 2021.

Regulatory Challenge Over Kalshi’s Offerings in Connecticut

The actions taken by Connecticut authorities against Kalshi follow months of regulatory scrutiny. The 24-page complaint requests both temporary and permanent injunctions, aiming to fully bar Kalshi from offering any type of sports wagering service within Connecticut’s borders. In addition to the operational halt, the state seeks to recover restitution and civil penalties for each specific violation. The complaint also asks the court to force Kalshi to give up all revenue, profits, and gains realized from what the state labels as "unfair and/or deceptive acts."

Connecticut’s officials see Kalshi’s event contracts as sports wagers rather than investments. Attorney General Tong emphasised, > "Kalshi’s offering was not 'magically shielded' by federal law from the state’s commonsense consumer protection laws," highlighting the risk to consumers the state is aiming to curb.

State Arguments: Consumer Protection and Market Integrity

Connecticut’s leadership made clear the lawsuit aims to preserve the integrity and safety of its regulated betting market. Tong and Cafferelli both asserted that Kalshi’s product design and marketing target vulnerable populations, including minors and self-excluded gamblers. The state claims Kalshi does not meet local technical requirements for data and funds protection laid out by Connecticut’s gaming law.

Governor Ned Lamont noted that legal sports betting was introduced "to create a safe, responsibly regulated market for Connecticut consumers, not to open a free-for-all on sports betting." Commissioner Cafferelli reinforced this by stating, > "These markets have been waging a coordinated campaign to convince people they are offering investments that are somehow safe when the reality is they are indistinguishable from sports wagering."

Other state-level assertions include:

• Kalshi does not adhere to technical and consumer protection standards required of licensed operators
• Its platform has exposed minors and self-excluded individuals to betting markets
• Kalshi’s activities fundamentally violate Connecticut’s gambling laws

Kalshi’s Response and Claims of Unequal Enforcement

Kalshi disputes Connecticut’s interpretation, asserting it is operating legally under federal Commodity Futures Trading Commission (CFTC) oversight and does not need state licensure. The company classifies its contracts as “swaps,” a financial product rather than bets. Jovy Dedaj, Kalshi’s head of litigation, criticised the state’s "arbitrary and inconsistent enforcement," highlighting that other prediction markets are allowed to operate in Connecticut. Dedaj stated, “This unequal treatment is exactly why federal oversight is necessary.”

Kalshi previously filed suit against Connecticut, arguing its contracts were federally regulated swaps, not sports wagers. The case was dismissed by US district judge Vernon Oliver, who ruled in August that Kalshi’s sports event contracts meet the definition of sports wagering under state law.

Broader Enforcement Context and Ongoing Litigation

Connecticut’s case against Kalshi is part of a wider clampdown. In December of the previous year, the Department of Consumer Protection Gaming Division issued cease-and-desist letters not only to Kalshi but also to Robinhood and Crypto.com, alleging unlicensed sports betting operations.

Judicial setbacks for Kalshi have mounted across multiple jurisdictions. Over the past 12 months, the company lost court challenges in New York, Washington, and Nevada. In Nevada, Kalshi agreed to implement third-party geofencing to stop state residents from accessing its platform.

What This Means for Operators and Market Participants

The complaint against Kalshi puts other prediction markets and new entrants on notice about Connecticut’s stance on the boundaries between federally regulated event contracts and state-licensed sports betting. It underlines the risk for any platform offering sports event-related products without explicit state authorisation. Industry professionals should expect continued friction between state regulators and operators claiming exemption via federal commodities regulation—a dynamic affecting both market access and compliance for platforms operating at the intersection of sports and alternative wagering formats.
