FlightAware sues Kalshi over flight cancellation data
Summary
FlightAware sued Kalshi in New York federal court, alleging the prediction market used FlightAware’s trademark and flight data without permission to offer betting contracts on flight cancellations. FlightAware says it repeatedly demanded Kalshi stop, but the contracts continued. The company argues the markets could mislead customers into thinking FlightAware endorsed the wagers, harm its reputation, and create public-safety risks by incentivizing interference with air travel or pressure on workers to alter outcomes. The lawsuit also says flight-related event contracts may amount to unlawful gambling and joins a wider wave of legal challenges against prediction markets like Kalshi and Polymarket.
