What is the Kalshi lawsuit?
The Kalshi lawsuit is a civil action filed by the Commonwealth of Massachusetts alleging that Kalshi offers unlicensed sports wagering to state residents by listing sports-related event contracts. The suit seeks to enforce Massachusetts gambling statutes against Kalshi while Kalshi maintains it falls under federal CFTC oversight.
How does Massachusetts say Kalshi violated state law?
Massachusetts’ complaint, filed in Suffolk County Superior Court, argues Kalshi masks sports bets as “event contracts” to evade the state’s sports wagering regulations. The filing cites internal volume figures and market composition data, asserting sports-related trading dominates Kalshi’s platform activity.
In comments to Cointelegraph, Kalshi claimed that Massachusetts is “trying to block Kashi’s innovations by relying on outdated laws.”
Prediction market operator Kalshi announced it will defend the platform against the Massachusetts lawsuit, saying the complaint misunderstands the nature of federally regulated event contracts.
“We are proud to be the company that has pioneered this technology and stand ready to defend it once again in a court of law,” a Kalshi spokesperson told Cointelegraph in prior comments. The company adds that prediction markets represent modern financial innovation and should be accessible under appropriate federal oversight.
Why does Kalshi argue the CFTC regulates these markets?
Kalshi argues that its event contracts are within the Commodity Futures Trading Commission’s (CFTC) federal jurisdiction, not subject to state gambling enforcement. The company points to prior CFTC guidance and federal authority over derivatives-style contracts as the basis for its defense.
What precedents and related actions exist?
Kalshi has previously received cease-and-desist orders from multiple states, including Arizona, Montana, Ohio, and Illinois. Regulators and companies in this sector frequently reference federal guidance from the CFTC and state gambling laws when assessing jurisdiction.

The Massachusetts filing stated that as of May 2025, more than three-quarters of Kalshi’s trading volume was related to sports, a proportion the state said exceeded comparable shares at some established operators. Kalshi disputes the legal framing and emphasizes federal regulatory channels.
How does this case relate to other market entrants like Polymarket?
Industry developments include activity by other blockchain-based prediction platforms. Polymarket has announced plans to explore a U.S. return, with public statements referencing CFTC engagement. Business Insider reported on funding interest and market valuation conversations in the sector, while Polymarket’s leadership has referenced CFTC approvals in social posts.
Frequently Asked Questions
Question 1: How will the court decide jurisdiction?

Question 2: What does this mean for users in Massachusetts?
Practically, users should monitor court rulings; state enforcement could affect access or platform features for Massachusetts residents. Companies may restrict state access during litigation to limit legal exposure.
