Polymarket and Kalshi contest state action over US prediction markets
Polymarket and Kalshi are challenging state action over prediction-market sports contracts in Massachusetts, Nevada and Connecticut, according to the report. Massachusetts Attorney General Andrea Joy Campbell is named in a federal case brought by Polymarket, while the Nevada Gaming Control Board filed a civil complaint against the platform. Connecticut officials issued a cease-and-desist order to Kalshi, which has also sued the state; the report says a two-month delay has been granted.
The cases could affect whether prediction-market platforms can offer sports contracts across these US states.
