FlightAware drops Kalshi lawsuit one day after filing
Flight tracker voluntarily dismissed its complaint without prejudice; Kalshi subsequently updated at least one contract to cite a 'Primary Source Agency' for data verification
Briefing
- FlightAware filed suit against Kalshi alleging unauthorized use of its proprietary data and trademark to operate flight cancellation prediction markets, seeking a temporary restraining order.
- FlightAware voluntarily dismissed the lawsuit without prejudice just one day after filing, giving no public explanation for its decision.
- Following the lawsuit, at least one of Kalshi's event contracts was amended to list 'Primary Source Agency' as the entity responsible for verifying flight cancellation data.
- The flight cancellation markets at the center of the dispute had attracted little traction with Kalshi users, according to data cited by CoinDesk.
- The complaint had raised intellectual property claims as well as a safety argument that financial incentives tied to cancellation outcomes could encourage disruptive tactics.
- Because the dismissal was without prejudice, FlightAware retains the option to refile; the underlying questions about third-party data use as settlement oracles remain unresolved.
Analysis
- Kalshi and rival prediction market platforms face a structural compliance cost increase as courts establish whether third-party data licensing is a prerequisite for event contract settlement. If the TRO is granted and the flight cancellation markets are suspended, it creates a direct precedent that any prediction market using proprietary real-time data as a settlement oracle without a formal license is operating with actionable IP liability. Polymarket and similar venues using weather, sports, or financial data feeds face analogous exposure.
Historical Context
- 2021-2022
CFTC rejected Kalshi's original political event contracts before reversing course under a new administration. The regulatory history establishes that Kalshi's contract categories have repeatedly tested the boundary of what is permissible, making a court-granted TRO here politically and regulatorily significant beyond the IP dispute itself.
- 2007-2009
Courts ruled against Contractual data scraping in cases like Associated Press v. All Headline News, establishing that systematic commercial use of proprietary real-time data without licensing constitutes misappropriation even absent copyright. FlightAware's claims likely invoke this lineage, not just trademark.
