FlightAware withdraws its Kalshi lawsuit, after alleging Kalshi used its data to let users bet on flight cancellations; Kalshi no longer names it as a source
Flight-tracking company FlightAware withdrew its lawsuit against Kalshi on Tuesday, a day after it filed the suit that accuses …
Context & Ripple Effects
FlightAware's withdrawal comes one day after its New York complaint over alleged use of flight data for cancellation contracts. Kalshi has also been contesting the boundaries of oversight for its event contracts, including its challenge to Nevada gaming regulators.
The immediate change is narrow but consequential: Kalshi no longer identifies FlightAware as a source, removing the named attribution that sat at the center of the dispute without establishing a judicial answer on permission to use the data.
First-order effects
- FlightAware ends its active suit against Kalshi, while Kalshi removes FlightAware from its named data sources for flight-cancellation betting.
- Kalshi must operate its relevant market disclosures without identifying FlightAware as the source, and FlightAware avoids a longer public fight over its data-use terms.
Second-order effects
- Other data providers serving event-contract markets gain a concrete reason to review whether their data is being named or used in market design without an explicit agreement.
- Kalshi's disclosure and sourcing practices become a more immediate operational issue as it expands products while facing separate disputes over the regulatory treatment of its contracts.
Third-order effects
- If data owners increasingly challenge prediction-market uses, access rights and source attribution may become a competitive constraint alongside the CFTC-versus-state-regulator questions already surrounding Kalshi.
- The episode points toward event-contract platforms needing clearer commercial and disclosure arrangements for specialized real-world data, rather than treating availability as permission.
The trend: Prediction markets are confronting a two-front governance test: regulatory authority over contracts and permission to use the data that settles them.
