Polymarket Files Lawsuit In Massachusetts To Prevent Shutdown
In a preemptive move, Polymarket filed a lawsuit against Massachusetts.
This legal step by the prediction markets operator comes on the heels of the state’s success in forcing Kalshi to wind down its sports‑prediction business in Massachusetts, under a Jan. 20 court order.
Polymarket, which bills itself “the world’s largest prediction market,” wants to challenge the state’s application of state gambling laws to sports events contracts offered by the company and its competitors like Kalshi.
Polymarket’s Legal Claims
Filed on Feb. 9, Polymarket claims that the lawsuit aims “to prevent imminent and irreparable harm arising from Massachusetts’s enforcement of state gambling laws against federally regulated derivatives exchanges” and notes that Congress prohibits such action.
In the case against Kalshi, a Massachusetts state judge sided with the state’s Gaming Commission in asserting that the Polymarket competitor was operating without the necessary licensing for sports betting within the state.
Polymarket argues that the Commodity Futures Trading Commission should have exclusive authority over event contracts, in line with Congressional mandate. The company contends that state regulations should not apply and that the CFTC’s jurisdiction is clear and preempts state laws. For prediction markets, state enforcement poses risks, including civil penalties, potential criminal liability, and disrupted operations, according to Polymarket.
What if Polymarket succeeds?
In its legal battle, Polymarket faces a state with some of the toughest sports betting rules in the country. It will be an uphill battle in Massachusetts as regulators have repeatedly voiced deep skepticism about sports‑related prediction markets. Along with other lawmakers across the country who are wary of prediction markets, they cite concerns for consumer protection, lack of regulatory oversight, and fears that unethical behavior, such as manipulating public events or outcomes for financial gain, could result.
However, if Polymarket succeeds in this lawsuit, it could significantly alter how prediction markets are regulated across the United States and some states may take the approach of New York to crafts its own regulations for the industry.
