What happened
FlightAware is suing prediction market platform Kalshi for allegedly using FlightAware's real-time flight data and branding to host flight cancellation betting markets without authorization. FlightAware claims Kalshi continued displaying its data and name even after being told to stop, and argues these markets could be manipulated to interfere with flights, posing safety risks.
Why it matters
If you build products that surface or aggregate third-party data, this case is a concrete reminder that scraping or republishing another company's data and branding without a licensing agreement can lead to litigation—even if the data is publicly accessible. Builders using flight, weather, financial, or other real-time feeds should verify their data source terms before embedding that data into commercial products or prediction features.
Discussion angle
Where is the line between fair use of public data and unauthorized commercial exploitation, and how should builders think about Terms of Service and branding when building on third-party APIs?
