FlightAware sues Kalshi over unauthorized data use
Legal action initiated against prediction market platform for alleged copyright infringement.
1Alleged violation at core of lawsuit
FlightAware accuses prediction market platform Kalshi of unauthorized use of its flight data and trademark. The company claims Kalshi created betting markets based on 'flight cancellation rates' using this data. FlightAware sent a cease-and-desist letter but alleges the unauthorized usage continued despite violation of terms of service.
2Legal proceedings underway
The lawsuit was filed in New York, where state Attorney General Letitia James has separately sued Kalshi for operating an illegal gambling business. FlightAware seeks damages and a permanent injunction to prevent Kalshi from using its data. The company also claims trademark infringement has damaged its reputation.
3How the data usage was discovered
FlightAware learned about Kalshi's data usage when media outlets requested comments. It was revealed that since July 2026, Kalshi allowed users to bet on flight cancellation rates at specific airports. FlightAware had explicitly told Wall Street Journal it would never authorize such uses of its data network.
4Industry concerns raised
The airline industry warns that prediction markets for flights could incentivize 'mass disruption of air travel.' FlightAware's lawsuit references these concerns, suggesting bad actors might deliberately cause flight disruptions to profit on Kalshi's platform. The case highlights emerging ethical questions in prediction markets.
5Kalshi's preventive measures
Kalshi implemented insider trading rules, verifying users' employers for certain bets and blocking politicians from betting on elections or athletes on games. However, many states still classify the platform as gambling and seek stricter regulation. The New York lawsuit presents a critical test for the platform's legal standing.
6Regulatory battle continues
The Commodity Futures Trading Commission, Kalshi's designated regulator, has resisted attempts to restrict the platform. However, New York's lawsuit could shift this dynamic. The case outcome may set important precedents regarding the legal status of prediction markets in the U.S. financial system.
7FlightAware's firm stance
FlightAware maintains an absolute prohibition against using its data for prediction markets, stating no company is or will be authorized for such purposes. The company warns of account termination for any customer violating terms of use. FlightAware alleges Kalshi continued data usage despite these clear warnings.
8Broader industry implications
The lawsuit could become a landmark case in data ownership and licensing, particularly defining what data emerging financial instruments like prediction markets can legally use. The inclusion of airline industry concerns expands the case's potential impact beyond copyright into transportation sector regulations.
