Michigan Attorney General Dana Nessel is seeking to block prediction market firm Kalshi from offering sports-related event contracts to residents of the state, alleging the products amount to unlicensed sports betting under Michigan law.
The lawsuit, filed last month in the 30th Judicial Circuit Court, asks the court to permanently prevent Kalshi from offering or facilitating contracts tied to the outcomes of sporting events for users located in Michigan. State officials argue that these contracts function similarly to traditional sports wagers and therefore fall within Michigan’s regulated sports gambling framework.
According to the complaint, Kalshi allows users to buy and sell contracts based on whether specific events will occur. Some of those contracts relate to sports outcomes—for example, whether a team will win a championship or whether a particular result will occur in a sporting event. Users can profit if their prediction proves correct.
Michigan regulators contend that these transactions effectively allow participants to stake money on the outcome of sporting events without obtaining the licenses required for sports betting operators under state law.
The lawsuit further argues that permitting such contracts undermines Michigan’s regulated sports wagering system. Under that system, operators must obtain licenses, comply with consumer-protection measures, and pay taxes to the state. Officials say Kalshi’s products circumvent those safeguards.
Kalshi, however, maintains that it operates lawfully under federal law as a regulated derivatives exchange. The company is overseen by the Commodity Futures Trading Commission, which regulates futures, options, and other derivatives markets.
Under Kalshi’s view, its event contracts are financial instruments rather than gambling products. The company argues that because it is federally regulated as a designated contract market, its offerings fall under federal commodities law rather than state gambling statutes.
The dispute reflects a broader regulatory struggle over prediction markets. Platforms offering contracts tied to real-world events—including politics, economic indicators, and sports—have drawn increasing scrutiny as regulators debate whether the products function as financial derivatives or unregulated forms of gambling.
