Washington Court Blocks Kalshi Event Contracts Over Gambling Concerns

A King County judge has issued a preliminary injunction blocking Kalshi’s event contracts in Washington state. This action stems from concerns that these contracts may violate state gambling laws, according to Devdiscourse.

What Happened

Judge John McHale of King County Superior Court has issued a preliminary injunction preventing Kalshi from offering its event contracts in Washington state, according to Devdiscourse. This judicial action was taken due to concerns regarding potential violations of state gambling laws. The court’s order aims to safeguard consumers from engaging in what it considers illegal gambling activities.

Kalshi, an online prediction market, disputes this ruling. The company asserts that the regulation of its event contracts falls under federal jurisdiction, specifically citing the Commodity Futures Trading Commission (CFTC), as reported by Devdiscourse. This legal challenge in Washington is part of a broader trend, with other states also initiating court actions against Kalshi.
