Michigan authorities continue pursuit to block Kalshi as Supreme Court fight looms

Michigan’s Attorney General, Dana Nessel, has announced a significant legal victory in her ongoing efforts to curb what she describes as unlawful sports betting operations masquerading as legitimate investment opportunities. A state court has issued a preliminary injunction against Kalshi, a prediction markets platform, effectively prohibiting its services to residents of Michigan. This ruling carries substantial financial penalties for the company, with potential fines reaching up to $500,000 per day for any violations of the court’s order.

The injunction was approved by the Circuit Court for the 30th Judicial Circuit in Ingham County, as detailed in a notice issued by Attorney General Nessel’s office on a Wednesday. The order specifically bars Kalshi from offering its event contracts to individuals residing in Michigan. Attorney General Nessel expressed her relief at the court’s decision, stating, "Kalshi long attempted to pass itself off as a legitimate gaming operation in our state, and I am relieved that this order further protects Michigan residents from its predatory, unlicensed practices."

This legal action in Michigan is part of a broader and intensifying wave of scrutiny and litigation targeting prediction market companies, including Kalshi and Polymarket, by various US state authorities. Attorney General Nessel initiated her lawsuit against Kalshi in March, asserting that the platform’s operations violate Michigan’s state laws concerning sports gambling. This claim mirrors the allegations leveled against such platforms in numerous other legal challenges across the country.

The preliminary injunction follows a previous development in June, when a Michigan court issued a restraining order that similarly barred Kalshi from offering sports betting services to state residents. In a complex turn of events, the US Commodity Futures Trading Commission (CFTC) subsequently instructed Kalshi not to comply with the state’s order and to continue its operations. This directive from the CFTC placed Kalshi in what the company described as an “impossible position,” caught between conflicting regulatory mandates from state and federal authorities.

Cointelegraph sought comment from Kalshi regarding these developments but had not received an immediate response at the time of reporting.

New Jersey Petitions US Supreme Court to Weigh In on Prediction Markets

Coinciding with the Michigan court’s order, officials in New Jersey made a significant move by announcing their filing of a petition for a writ of certiorari to the US Supreme Court. This petition concerns New Jersey’s own legal case against Kalshi and seeks to have the nation’s highest court review the matter. If the Supreme Court agrees to hear the case, it could potentially resolve the contentious legal debate over whether federal regulators like the CFTC or individual state authorities hold primary jurisdiction over prediction markets.

Melinda Roth, a visiting professor of practice at New England Law in Boston, commented on the likelihood of the Supreme Court taking up the case. She suggested that while it would be reasonable for the Supreme Court to consider it, they might opt to wait for cases to be decided on their merits rather than solely on procedural issues like the granting of a preliminary injunction. Nevertheless, Roth expressed her belief that the Supreme Court will eventually address the issue, given the escalating volume of litigation in this domain, even if it’s not directly from New Jersey’s current petition.

Roth further elaborated on the potential impact of a Supreme Court review. "If and when SCOTUS takes it up, then this will likely decide whether sports event contracts are federally regulated by the CFTC or the states have the right to ban and/or regulate them as they see appropriate," she stated. She cautioned that this outcome is not absolute, as Congress could also intervene. "I say ‘likely’ because Congress might actually act too. They could act before a SCOTUS review, or even after too," Roth added, highlighting the possibility of legislative action influencing the regulatory landscape.

In parallel, some US lawmakers have been actively proposing legislation aimed at addressing concerns surrounding the use of insider information by customers of platforms like Kalshi and Polymarket on event contracts. In March, Senators Adam Schiff and John Curtis introduced bipartisan legislation designed to prohibit platforms registered under the CFTC from listing any event contract that bears resemblance to a sports bet or casino-style game. This proposed bill explicitly defers jurisdiction over such matters to individual state authorities.

The ongoing legal battles and legislative proposals underscore the growing tension between emerging prediction market platforms and established regulatory frameworks. The outcome of these cases, particularly any potential review by the US Supreme Court, could significantly shape the future of prediction markets in the United States, defining the boundaries of federal and state regulatory authority.
