Headline: FlightAware sues Kalshi over flight-cancellation betting markets, raising new legal and safety questions for prediction platforms Flight-tracking firm FlightAware has filed suit against CFTC-regulated prediction market operator Kalshi, accusing the company of using its proprietary flight data and brand without permission to settle newly launched flight-cancellation markets. The complaint, filed Monday, seeks emergency court orders to stop Kalshi from relying on FlightAware’s information and name in connection with the contested contracts. What FlightAware alleges - FlightAware says Kalshi rolled out markets last month that let users bet on whether individual flights would be canceled, and that Kalshi represented the outcomes were “verified from FlightAware.” - According to the complaint, Kalshi never informed FlightAware that it would use the company’s tracking data to determine contract payouts. “Kalshi never informed FlightAware that it would rely on FlightAware’s data to determine the outcome of these betting markets,” the filing says. - FlightAware’s claims include breach of contract, trademark infringement and unfair competition. The company is asking for a temporary restraining order and preliminary and permanent injunctions to bar Kalshi from using FlightAware’s services and branding for the disputed markets. Reputational and safety concerns - Beyond contractual disputes, FlightAware argues Kalshi’s naming of the company in its verification process gave users the false impression that FlightAware had approved or participated in the betting product—creating reputational risk for a business relied on by commercial and private aviation operators. - FlightAware also warned of potential safety incentives: even though Kalshi excludes payouts for cancellations due to malicious acts or security events, FlightAware says the existence of financial rewards tied to real-world cancellations could encourage unsafe attempts to influence flight operations—threatening travelers and airline systems. The complaint does not allege any instance of a trader successfully interfering with a flight. How Kalshi’s markets work - On Kalshi, traders take positions on whether a specified flight will be canceled; Kalshi then uses a stated verification source to settle and pay out positions. FlightAware contends Kalshi profited from using its data and reputation as part of a commercial betting product without securing permission. Regulatory and legal backdrop - The FlightAware suit follows a wave of legal challenges confronting Kalshi and other prediction-market operators as they expand from financial and political event contracts into sports and other real-world outcomes. - Kalshi argues that, as a CFTC-registered exchange, its event contracts are federal derivatives and should be preempted from state gambling laws. States and some courts have pushed back: - On July 31, New York Attorney General Letitia James and Governor Kathy Hochul sued Kalshi, accusing it of operating an unlicensed gambling business in the state and seeking at least $36 billion in damages and relief. Investigators said they were able to open accounts and execute transactions as part of the probe. - On July 21, a Washington state judge granted a preliminary injunction restricting Kalshi’s sports event contracts, signaling state gambling rules could apply despite federal registration. - On Aug. 6, a Michigan judge denied Coinbase Financial Markets’ request to block Michigan officials from applying state sports-betting laws to event contracts—another setback for prediction-market operators. - Contrastingly, on July 27 a federal judge in Minnesota blocked enforcement of a state ban against CFTC-registered designated contract markets while litigation continues, suggesting federal preemption may protect some—but not necessarily all—contracts. Why this suit matters to crypto and prediction markets - FlightAware’s action is notable because it targets data and trademark use rather than gambling classification. For crypto-native prediction platforms and derivatives markets that rely on external oracles and third-party data, the dispute underscores legal and commercial risks of integrating proprietary feeds without explicit agreements. - The case also highlights broader ethical and safety issues that emerge when financial incentives attach to discrete real-world events—concerns that apply whether the market is run on a centralized exchange, a CFTC-registered DCM, or a blockchain-based protocol. What’s next - FlightAware is asking the court to enjoin Kalshi’s use of its data and branding while the breach-of-contract, trademark and unfair-competition claims proceed. The suit may produce a quick preliminary ruling on whether Kalshi must immediately stop using FlightAware as a verification source. - The outcome could influence how prediction markets structure verification mechanisms and contract design going forward—and could prompt platforms to secure express permissions from data providers or to rely on neutral, consented oracles. Takeaway Kalshi’s flight-cancellation markets have triggered not only regulatory fights over whether prediction contracts are gambling, but also intellectual property and safety disputes tied to how those markets are verified and marketed. For the prediction-market and crypto ecosystems, the FlightAware lawsuit is a reminder that using third-party real-world data—especially in markets that tie money to discrete events—carries legal, reputational and ethical consequences.
