Prediction market Kalshi is being sued for allowing people to bet on airline flight cancellations.

Kalshi faces a lawsuit over claims it is using flight data and a trademark without permission to enable people to gamble on flight cancellations.

FlightAware, which operates the world's largest flight-tracking platform, filed the lawsuit in New York, seeking damages and an injunction against further use of its data and logo.

More From Cryptoprowl:

Kalshi started offering bets on nationwide and local flight cancellations in the U.S. on July 14.

The privately held prediction market is allowing people to bet on the percentage of scheduled flights that would be canceled during a specific period of time.

FlightAware alleges Kalshi had agreed to terms barring commercial use of its data and logo but the prediction market has since broken that agreement.

FlightAware also claims that Kalshi has ignored a cease-and-desist letter, claiming "fair use" of the company's logo and data.

Kalshi recently added a disclaimer on its website stating that the flight cancellation betting is not endorsed by FlightAware.

FlightAware also says that betting on flight cancellations creates safety risks by giving people a financial incentive to influence whether airline flights are delayed or canceled.

This is one of several lawsuits filed against Kalshi in recent months. In July, New York State sued Kalshi alleging it offers sports and event betting without a state gaming license.

The states of Wisconsin and Nevada have filed similar lawsuits against Kalshi.

As a private company, Kalshi's stock does not trade on a public exchange.
