FlightAware is taking legal action against Kalshi, alleging the prediction-market operator misused its flight-tracking data and trademarks to run betting markets on flight cancellations. The suit, filed in a New York federal court, names Kalshi Inc., KalshiEX LLC, Kalshi Klear Inc. and Kalshi Klear LLC. FlightAware seeks damages and an injunction to stop Kalshi's use of its data and branding in cancellation markets.
The complaint states Kalshi breached a binding agreement not to use FlightAware's data for commercial purposes, including gambling or prediction markets, after FlightAware demanded the halt. Despite this, Kalshi allegedly continued using FlightAware's data and name in its markets. FlightAware claims it entered into an AeroAPI account agreement with Kalshi in July 2022, under terms restricting commercial use, but Kalshi allegedly opened another FlightAware account on July 14, 2026.
Kalshi claims its use amounted to nominative fair use but FlightAware maintains its references were not authorized. The dispute comes after Kalshi faced criticism for using NCAA trademarks in March Madness prediction markets.
