Scott Bright filed a lawsuit in King County Superior Court on September 24, 2026, demanding the prediction market return over $580,000 for allegedly violating Washington’s online gambling ban.
The Financial Scale of the Kalshi Lawsuit
Scott Bright, a resident of Bellevue, Washington, moved $315,353.94 into Kalshi through 253 separate bank debits over an eight-week span this summer. The platform turned that money over in more than $14.3 million worth of trades on tennis matches, baseball games, and other sporting events.
When the trading activity concluded, Bright had lost $308,781.62. During this same period, Kalshi kept $89,651.76 in fees.
The legal complaint, filed on September 24 in King County Superior Court, argues that the wagering took place at a time when online betting was unlawful in Washington. The filing notes that the Washington Attorney General had already sued KalshiEX LLC in the same court alleging the exact same violations. Bright’s lawsuit aims to turn his multi-thousand-dollar losses into an overall victory by seeking a payment of over $580,000.
Court Filings and Legal Strategy
The case raises a central legal question for software platforms that match buyers and sellers of event contracts: is the platform a federally regulated exchange, or is it an online casino banned by Washington state law?
Kalshi has responded to the litigation by attempting to move the venue. The prediction market wants the case heard in the US District Court for the Western District of Washington. Additionally, Kalshi filed a motion to dismiss the lawsuit the following month and requested that the court put the case on hold.
While state attorneys general across the United States are actively trying to shut down Kalshi for allegedly violating state gambling laws, Bright’s individual lawsuit tests a different legal avenue. Specifically, the case examines whether unsuccessful gamblers can successfully obtain financial restitution directly from the company through individual civil lawsuits.
What Tech Consumers and Developers Should Watch Next
Tech consumers, gadget buyers, and developers tracking prediction markets should monitor how federal and state courts handle the jurisdictional battle between Kalshi and the state of Washington. The outcome of Kalshi’s motion to dismiss in the US District Court for the Western District of Washington will help clarify the legal boundaries for event-contract platforms operating across state lines. Furthermore, observers should watch whether similar individual restitution lawsuits emerge from gamblers in other states where online prediction market betting faces state regulatory bans.
