FlightAware sues Kalshi over flight-cancellation prediction markets

FlightAware sued Kalshi, saying Kalshi used its real-time flight-tracking data and name without authorization to settle prediction markets on cancellations—by the number of U.S. flights canceled, or by a specific airport. FlightAware claims it demanded Kalshi stop but the company continued displaying FlightAware branding and information. FlightAware sought court orders barring Kalshi from using its data and sought unspecified damages. Kalshi did not immediately respond to requests for comment.
