Kalshi asks court to dismiss Washington man's $580,000 gambling-recovery suit
KalshiEX LLC and Kalshi Inc. moved to dismiss a lawsuit filed in federal court in Seattle by a Bellevue, Washington man who claims he lost $308,000 trading event contracts on the platform. The man is seeking $580,000 in recovery, alleging the contracts violate Washington's ban on online gambling. Kalshi countered that its products are regulated event contracts subject to the Commodity Exchange Act. The suit represents a direct challenge to Kalshi's characterization of its products as regulated financial instruments rather than gambling.
This suit opens a second front that federal preemption cannot easily close. The plaintiff is not a regulator or tribe; he is a trader invoking a winner-pay-loser gambling-recovery statute that treats Kalshi as the house. That theory sidesteps the CFTC-registration defense Kalshi has wielded against state agencies, because Washington law assigns civil liability regardless of how the product is labeled federally.
Traders in Washington, Ohio, Tennessee, Louisiana, and Arkansas now have a copyable template for individual recovery actions. Kalshi's motion to dismiss suggests it wants this case before a judge who might accept its federal-label argument. A ruling against Kalshi in private litigation would expose it to damages formulas that scale with every trader's losses, a risk no single federal ruling can cap. Robinhood and Polymarket face identical exposure in states with similar statutes.
Joins Ohio, Tennessee, Louisiana, and Arkansas as jurisdictions where Kalshi faces parallel legal assaults on its federal preemption shield, alongside the separate felony arraignment of co-founders Mansour and Lopes Lara in Utah's criminal case.
