Connecticut's new lawsuit against Kalshi piles on to prediction market legal fight

Connecticut has filed a lawsuit against the prediction market platform Kalshi, seeking to halt its sports betting operations in the state. This move escalates a broader legal battle between state regulators and federally regulated trading platforms over consumer protection and gambling laws.
Why it matters
The case tests the boundaries of state-level consumer protection laws versus federal regulatory authority over emerging financial prediction markets.
So far, local and federal courts have produced a mixed bag of decisions on halting platforms such as Kalshi, a leading name in the U.S. That company is often in the middle of the legal fights, and it said in an online posting on Thursday that the result of its battles so far "is currently close to 50-50."
Connecticut had already been in a dispute with Kalshi since late last year, when the New England state ordered the company to shut down its sports betting, asserting that the activity violated the state's gambling regulations. Kalshi sued Connecticut to try to stop the order and initially lost, though the firm appealed to the Second Circuit Court of Appeals.
The Commodity Futures Trading Commission also sued Connecticut (and other states) for their prediction market interventions, claiming that the states have no say over the activities of a federally regulated trading platform.
