FlightAware sues Kalshi over flight cancellation prediction markets

The real-time flight tracker FlightAware is suing the prediction market Kalshi for allegedly using its data to host gambling markets.

Kalshi started letting users bet on the number of flights cancelled in the U.S., or at a given airport, about a month ago. According to FlightAware, Kalshi used FlightAware’s data and name without authorization, displaying FlightAware’s branding and information even after the flight tracker demanded that Kalshi stop.
