Legal & Market Structure Evidence Map
In FlightAware v. Kalshi (2024-2025), aviation data provider FlightAware challenged Kalshi's use of its flight tracking data feeds to settle regulated binary flight-cancellation options contracts. FlightAware alleges breach of API Terms of Service, commercial misappropriation, and unauthorized derivative work creation.
Settlement Risk Insight: When a binary contract settles on external API data, any discrepancies—such as a flight diverted to an alternate airport being classified as "Diverted" by the airline but "Cancelled" by an API scraper—can trigger multi-million dollar dispute arbitrations. Under current conditions for route JFK-ORD, data feed discrepancy risk is evaluated at High (82/100).
