- Kentucky is challenging prediction market platforms over sports event contracts.
- States and federal regulators disagree on whether these contracts are gambling or financial products.
- Court decisions could determine the future rules for US prediction markets.
Kentucky has become the latest US state to challenge the rapidly expanding prediction market industry, filing lawsuits against five platforms over sports event contracts. The legal action targets major names including Kalshi and Polymarket, with the state arguing that these platforms are operating unlicensed gambling services rather than regulated financial markets.
The case adds another layer to a growing national dispute over whether prediction markets should fall under state gambling laws or federal commodities regulations. As the industry gains billions in trading activity, regulators and companies are preparing for a legal fight that could shape the future of event-based trading in America.
Kentucky Targets Prediction Market Platforms Over Sports Contracts
Kentucky Attorney General Russell Coleman announced lawsuits against Polymarket and Kalshi, while also naming Kalshi partners including Coinbase, Robinhood, and Webull. The state claims the companies are offering sports wagering products without the required gaming approvals.
Kentucky officials argue that sports-related event contracts closely resemble traditional betting markets and should be regulated under state gambling rules. The lawsuits also accuse the platforms of failing to provide adequate gambling safety measures, including resources for users facing potential gambling problems.
The companies reject those claims. Polymarket maintains that its contracts operate within the regulatory framework established by the Commodity Futures Trading Commission (CFTC). Kalshi has also argued that it is a federally supervised exchange and that state authorities do not have control over its operations.

A Growing Legal Conflict Across US States
Kentucky’s lawsuit is part of a wider regulatory battle involving more than a dozen states. Authorities in states including Montana, Nevada, New York, Ohio, and New Jersey have taken action against prediction market companies, while some platforms have responded with lawsuits of their own.
The central disagreement focuses on whether sports event contracts are gambling products or financial instruments. State regulators say the contracts fall under sports betting laws, while prediction market operators argue they are swaps covered by federal commodities rules.
The CFTC has supported the federal regulatory position and has challenged several state actions, saying states may be interfering with federal authority over commodity markets.
Prediction Markets Face Uncertain Future as Courts Weigh In
Court decisions so far have produced mixed outcomes. Some judges have supported state regulators, including a Michigan ruling involving Polymarket that questioned whether sports event contracts qualify as swaps under CFTC oversight.
Other courts have taken a different view. The Third Circuit Court of Appeals previously ruled that New Jersey regulators could not block Kalshi from offering sports-related contracts in the state.
With prediction markets recording significant growth — including billions of dollars in monthly trading volume — the outcome of these legal battles could influence how the industry develops. Political attention has also increased, with President Donald Trump supporting continued federal authority over prediction markets.

The Kentucky lawsuit highlights a broader struggle over the future of prediction markets in the United States. As states push for tighter control and companies defend federal oversight, upcoming court decisions may determine whether these platforms expand, face restrictions, or require major changes to their business models.
