Summary
- Flight-tracking company FlightAware has sued prediction market platform Kalshi in federal court in New York, alleging unauthorized commercial use of its flight data and trademark to run bets on airline cancellations.
- The complaint says Kalshi violated FlightAware’s license terms, ignored a cease-and-desist letter, and continued to reference FlightAware data for settling contracts even after adding a disclaimer that the markets were not endorsed by the company.
- The lawsuit comes as Kalshi already faces separate actions from New York, Wisconsin and Nevada over alleged unlicensed gambling, and could set a precedent for whether prediction markets may rely on third-party data and branding without a commercial agreement.
