Connecticut Sues Kalshi Over Alleged Unlicensed Sports Wagering
United States.- 28 August 2026 | www.zonadeazar.com Connecticut has filed a lawsuit against Kalshi seeking to prevent the prediction-market platform from continuing to offer sports-related event contracts to residents of the state.
Authorities argue that the products amount to sports betting and that Kalshi is operating without the state licence required to offer such services.
Connecticut Seeks Injunction
The state is asking the court for an injunction blocking Kalshi’s sports-related operations in Connecticut.
The action was announced by Attorney General William Tong, Governor Ned Lamont and Department of Consumer Protection Commissioner Bryan T. Cafferelli.
The aim is to stop the offering while the broader dispute over the applicable regulatory framework continues.
Products Challenged by State
Kalshi allows customers to purchase contracts tied to yes-or-no outcomes involving future events.
Its sports markets can include:
- Match winners.
- Team or player performance.
- Number of wins during a season.
- League rankings.
- Point totals.
- Point spreads.
- Individual player statistics.
Connecticut argues that these products are functionally equivalent to conventional sports betting.
Consumer Protection at Centre of Case
State officials say sports-event contracts should be subject to the same safeguards applied to licensed sportsbooks.
Connecticut has highlighted issues including:
- Protection of minors.
- Problem-gambling prevention.
- Security of customer funds.
- Personal-data protection.
- Technical platform standards.
- Self-exclusion systems.
Officials argue that these safeguards are not currently provided through Kalshi’s model.
December 2025 Enforcement Action
The latest lawsuit follows earlier regulatory action.
In December 2025, the Gaming Division of the Department of Consumer Protection ordered Kalshi and two other platforms to cease conducting unauthorised online gambling in Connecticut.
The action specifically targeted unlicensed sports wagering.
The companies were also directed to return money held on their platforms.
Kalshi Argues for Federal Jurisdiction
Kalshi rejects Connecticut’s interpretation.
The company argues that its prediction contracts are swaps regulated at federal level by the Commodity Futures Trading Commission.
Under that position, state authorities would not have jurisdiction to apply their sports-betting laws to the products.
Court Setback for Kalshi
Kalshi had already turned to federal court seeking to prevent Connecticut from enforcing its gambling laws against the platform.
Earlier in August, US District Judge Vernon Oliver denied the company’s request for a preliminary injunction.
Kalshi subsequently appealed the ruling to the Second Circuit Court of Appeals.
Emergency Relief Also Denied
The company also sought emergency relief while litigation continues.
A judge rejected that request and scheduled an in-person status conference for 17 September 2026.
The legal dispute will therefore continue over the coming weeks.
CFTC Becomes Involved
The dispute has also developed into a wider federal issue.
The CFTC has sued Connecticut and two other states while advancing a position similar to Kalshi’s.
The federal regulator argues that prediction markets fall under its exclusive jurisdiction.
Connecticut has responded by seeking dismissal of that lawsuit.
Statements
Attorney General William Tong argued that sports-event contracts are no different from conventional sports betting and should not escape state consumer-protection rules simply because Kalshi operates under a federal regulatory framework.
Commissioner Bryan T. Cafferelli also challenged the presentation of the products as investments, arguing that they are effectively indistinguishable from sports wagering.
Governor Ned Lamont highlighted potential risks to consumers, young people, student athletes and individuals affected by gambling-related harm.
Kalshi Claims Unequal Treatment
Kalshi responded by arguing that Connecticut is seeking to shut down its operations immediately while other prediction-market platforms remain available in the state.
The company says this demonstrates inconsistent state enforcement.
Kalshi has again argued for uniform federal oversight.
Federal Versus State Regulation
The case forms part of a much wider debate across the United States.
The central question is whether sports-related prediction contracts should be treated as federally regulated financial instruments or as sports betting subject to individual state laws.
The outcome will have significant consequences for Kalshi and other companies operating in the sector.
Industry Context
Sports prediction markets are expanding rapidly in the United States and increasingly competing with conventional sportsbooks.
At the same time, several states are taking legal action against platforms offering sports-event contracts without local gaming licences.
Commercial expansion is therefore taking place alongside an escalating legal battle over the limits of federal and state authority.
Next Steps or Impact
Connecticut’s lawsuit will continue while Kalshi pursues its appeal before the Second Circuit.
The status conference scheduled for 17 September will be one of the next procedural milestones.
The outcome could establish an important precedent over whether individual states can apply sports-betting laws to CFTC-regulated prediction markets or whether federal oversight overrides local restrictions.
