FlightAware Sues Kalshi Over Flight Data Use

FlightAware provides real-time flight tracking and aviation data, while Kalshi operates a regulated prediction market where users trade contracts tied to event outcomes. The dispute tests whether a market operator can use third-party operational data without permission to create and settle flight-cancellation contracts, raising broader questions about data licensing, commercial use and the integrity of event-based markets.

FlightAware has sued Kalshi, alleging the prediction-market platform used information from its website without authorization to offer markets on flight cancellations. The aviation-data company is seeking a temporary restraining order barring Kalshi from activities involving the disputed tracking data. The supplied event information does not specify the filing date, the contracts’ trading volume or any damages sought.
