FlightAware sues Kalshi over flight cancellation data

The legal action against Kalshi focused on trademark infringement and injury to its reputation in addition to citing state authorities comparing the company’s contracts to gambling.

FlightAware, a company that offers real-time status and information about flights globally, filed a lawsuit against Kalshi in a New York federal court over the prediction markets platform using its “data and name to run gambling markets on flight cancellations.”

In a Monday filing in the US District Court for the Southern District of New York, the company said that despite repeated demands for Kalshi to stop using its registered trademark and offering bets “verified by FlightAware’s data,” the prediction market has continued to list event contracts based on flight cancellations.

The lawsuit cited authorities’ claims that event contracts on prediction market platforms like Kalshi were “wagers” in violation of state laws, adding that the company’s expansion to trading on commercial flights starting in July was associating FlightAware with activities potentially harming its reputation. FlightAware sought to “stop Kalshi’s illicit behavior before there is any harm to public safety.”
