What Happened
Kentucky’s Attorney General filed lawsuits against prediction market operators Polymarket and Kalshi, along with their partners Coinbase, Robinhood, and Webull. The state accuses them of running illegal sportsbooks without the required gambling license. Kentucky law defines sports event contracts as sports wagering, and the AG claims the platforms made no effort to comply with state regulations or problem-gambling safeguards.
This action is part of a growing state-level crackdown. Michigan, Texas, and over a dozen others have initiated similar proceedings. A Michigan federal judge just ruled against Polymarket, heightening the uncertainty. The suits threaten to cut off access to some of the largest US markets.
The Numbers
Kalshi and Polymarket together handled $25 billion in monthly trading volume in May, according to Token Terminal. Kentucky’s new 14.25% tax on prediction market transaction fees signals a clear financial interest in regulating these platforms. At least 18 states—including Kentucky—have now taken legal action. The Michigan ruling marked a tangible setback for Polymarket, demonstrating that courts are not uniformly siding with the platforms.
Why It Happened
Prediction markets and state regulators disagree on a fundamental question: Are sports event contracts gambling or federally regulated derivatives? The platforms, backed by the CFTC, argue that their event contracts are swaps under federal commodities law. States see it differently. Kentucky’s lawsuit explicitly states the contracts fall within its definition of sports wagering.
The CFTC has sued eight states for interfering with its authority, but the legal landscape remains fragmented. States also see potential revenue. Kentucky’s freshly enacted tax on prediction market fees reveals a motive to capture a slice of the booming volume. The turf war between federal and state oversight is intensifying, with no clear resolution in sight.
Broader Impact
The outcome could reshape the US prediction market industry. A win for states may force platforms to stop serving residents in those jurisdictions or restructure products. It could also embolden more states to demand licensing, effectively Balkanizing the market. For crypto-adjacent platforms like Coinbase and Robinhood, the lawsuits expose them to legal liability they had not faced in this context before. The path to the Supreme Court appears increasingly likely.
What to Watch Next
- The Kentucky court’s initial response and any temporary restraining orders.
- Rulings in other active cases, especially the Michigan decision’s appeal.
- Whether the CFTC escalates its own lawsuits against states, forcing a federal resolution.
