FlightAware has filed a lawsuit against Kalshi, alleging unauthorized use of data for markets related to flight cancellations.

The company is also asking the court to temporarily prohibit Kalshi from activities related to the FlightAware website. The available description does not specify the amount of damages claimed, the specific legal provisions cited, or Kalshi's response.

This is significant for the market because the dispute concerns the boundaries of using specialized data in event-based products. However, The Block's publication consists only of metadata and a brief synopsis, so the details of the case require verification through court documents and statements from the parties.
