FlightAware Sues Kalshi Over Flight Cancellation Betting Markets
Flight-tracking platform FlightAware filed a lawsuit against Kalshi on Monday, August 10, 2026, alleging that the company used its data and branding without authorization to host betting markets on flight cancellations. The legal action targets Kalshi’s recent introduction of betting markets allowing users to wager on the number of U.S. flight cancellations or disruptions at specific airports.
Lawsuit Details Over Unauthorized Data Use
According to the lawsuit filed by FlightAware, Kalshi launched these betting markets approximately a month prior to the legal filing. The platform allowed users to place bets on flight disruptions without informing FlightAware that it intended to rely on the company’s real-time flight data to determine the outcomes. FlightAware stated that Kalshi displayed its branding and information even after receiving demands to stop. The flight tracker maintained that it remained entirely unaware of the arrangement until media outlets began reporting on the new gambling products, according to TechCrunch.
Safety Risks and Prediction Market Precedents
FlightAware argues in the court filing that hosting betting markets tied to operational infrastructure like commercial aviation poses a direct safety risk for travelers and airport employees, as these markets can potentially be manipulated by bettors. While prediction platforms such as Kalshi and Polymarket prohibit insider trading within their rules, past markets have faced intense scrutiny over manipulation. In a previous high-profile instance reported by TechCrunch, a Polymarket user placed a $32,000 bet that Venezuelan President Nicolás Maduro would be removed from power by the end of January, securing a $400,000 payout after the U.S. military captured Maduro hours later. In another instance on Kalshi, a White House teleprompter operator allegedly earned more than $100,000 by wagering on presidential speeches using advanced internal knowledge.
Legal Demands and Next Steps
FlightAware is seeking a jury trial in its lawsuit against Kalshi. The company has not specified an exact monetary amount for damages in the initial complaint. TechCrunch reported that it reached out to Kalshi for comment following the filing, while the prediction market has continued facing broader questions regarding the oversight of event-based wagering products.
