The big picture: Over eight weeks this summer, a Bellevue, Washington, man moved $315,353.94 into Kalshi through 253 separate bank debits, and the platform turned that money over in more than $14.3 million worth of trades on baseball games, tennis matches and other sporting events. When it was over, Scott Bright had lost $308,781.62, while Kalshi had kept $89,651.76 in fees. He is now suing to recover more than $580,000, and his case raises a hard question: is software that matches buyers and sellers of event contracts a federally regulated exchange, or an online casino that Washington law has banned?
Bright filed his complaint in September in King County Superior Court. Kalshi wants the case heard in the US District Court for the Western District of Washington. It filed a motion to dismiss the following month and has also asked the court to put the case on hold.
The complaint lays out the account's activity in detail. Between June and August 2026, Bright funded his Kalshi account through his checking account, and the platform allegedly charged $5,589.05 in funding fees on those transfers. He appears to have put his winnings straight back into new positions. That would explain why the trading volume ended up about 45 times larger than what he deposited.
71 in trading fees along the way. 7% of everything he put in. 27 was left in the account.
