What Happened
Baltimore and its mayor Brendan Scott filed lawsuits Thursday against prediction market platforms Kalshi and Polymarket, alleging they operate illegal, unlicensed sports-betting platforms and mislead users about legality. The complaint against Kalshi also names Robinhood, Webull, and Coinbase as partners accused of marketing sports contracts as lawful in Maryland. The city argues the trades amount to unlawful wagers under state laws, not federally regulated event contracts.
The Numbers
Two lawsuits target Kalshi and Polymarket. Three partner platforms—Robinhood, Webull, and Coinbase—are named in the Kalshi complaint. The case escalates an ongoing dispute between state authorities and the CFTC, where event contracts are classified as swaps under federal law. Experts expect the conflict to end with a Supreme Court appeal. No immediate trading volumes or price impacts were reported.
Why It Happened
The core dispute hinges on whether event contracts are swaps regulated by the CFTC or sports wagers subject to state gambling laws. Baltimore alleges the platforms relabeled sports betting as event contracts to dodge local licensing. This reflects broader regulatory ambiguity as prediction markets expand into sports, drawing scrutiny from state officials who see unauthorized gambling operations.
Broader Impact
The lawsuits could set a precedent for how prediction markets operate across the US. If state challenges succeed, platforms may face a patchwork of local rules, undermining the federal framework. The outcome could also affect major crypto exchanges offering event contracts, potentially limiting their product offerings.
What to Watch Next
- Watch for initial court rulings on whether event contracts are swaps under CFTC authority or wagers under state law.
- Monitor whether other cities or states file similar lawsuits against prediction market platforms or their partners.
- Track any appeal to the Supreme Court and its impact on Robinhood, Webull, and Coinbase product listings.
