Summary

Kalshi encounters another hurdle in Washington state as a judge rules in favor of the state's arguments.
Kalshi has been instructed to temporarily halt offering event contracts due to concerns from the judge about possible consumer harm.
The platform is encountering similar resistance in other states, including Michigan, Massachusetts, New York, Nevada, and beyond.

Kalshi is under growing scrutiny in the United States after a Washington judge agreed to block the platform's event contracts in the state. This decision will take effect early next month, by which time Kalshi must comply.

Washington judge sides with state against Kalshi - case ongoing

On Monday, July 20, Judge John McHale of the King County Superior Court decided in favor of Washington, granting the state's request to limit the company's ability to offer the disputed form of trades. Washington isn't the lone state challenging Kalshi; similar actions have been taken by Nevada, Michigan, Kentucky, Minnesota, and Massachusetts. Earlier, on July 8, New York issued a similar directive, denying Kalshi's request for a preliminary injunction against a decision blocking event contracts in the state. Judge McHale indicated that the state had effectively shown that Washington consumers faced substantial injury due to what he termed illegal gambling activities. However, Kalshi and other prediction markets argue that their offerings don't amount to gambling, as they fall under regulations by the Commodity Futures Trading Commission (CFTC).

Consumers could be harmed worse than Kalshi’s business interest

In making his decision, the judge noted that the potential harm to consumers outweighed the supposed impact on Kalshi. The legal fight over prediction markets continues, with businesses claiming that local state gaming laws should not override established federal regulations under the CFTC. This argument is starting to show weaknesses, as recent developments in Washington, Massachusetts, Michigan, and New York have indicated, but Kalshi remains very much in the fray. For instance, Judge Hale stated in a 14-page ruling that the Commodity Exchange Act does not supersede Washington State's gambling laws. Tensions have also risen over how insiders might exploit these platforms by trading based on non-public information. One example involves a long-time operator of President Donald Trump’s teleprompter, who reportedly settled a case after being caught betting on POTUS’ speeches. This case is not unique. To their credit, platforms like Kalshi and Polymarket have identified these incidents and increased their efforts to monitor for suspicious trading activities.
