FlightAware Sues Then Drops Kalshi Over Flight Cancellation Betting Data
FlightAware, the world's largest flight-tracking platform, filed a federal lawsuit against prediction market platform Kalshi on August 10th, accusing the company of using its proprietary flight data and trademark without permission to power betting markets on airline cancellations. The complaint alleged breach of contract, trademark infringement, and unfair competition. FlightAware claimed it only learned about Kalshi's flight cancellation markets through media inquiries in July, after Kalshi had already listed the company as the primary data source for settling bets. The lawsuit also raised safety concerns, arguing that financial incentives to influence flight cancellations could endanger passengers and disrupt operations. However, FlightAware voluntarily withdrew the lawsuit just one day later on August 12th without publicly disclosing whether the companies reached a settlement or what changes Kalshi may have made to the markets. The case had set up a novel legal question: whether prediction market platforms can use third-party data and branding to settle contracts without explicit commercial agreements.

How different outlets framed it
Left-leaning coverage: Left-leaning outlets stressed the public safety risks inherent in allowing financial incentives tied to flight cancellations, highlighting how prediction markets could encourage dangerous manipulation of airline operations. Coverage emphasized the lack of proper regulatory oversight, concerns about insider trading on these platforms, and the need for stronger consumer protections and state authority over such markets rather than relying on federal CFTC oversight designed for commodities futures.
Right-leaning coverage: Right-leaning and libertarian outlets emphasized Kalshi's argument that prediction markets function as valuable information aggregators and financial instruments—not gambling—and should operate under federal CFTC oversight rather than face patchwork state restrictions. They highlighted the company's legal victories in court and the Trump administration's support for federal preemption, framing state-level opposition as protectionist overreach by gambling lobbies protecting their turf.
Limits of this briefing
The lawsuit's rapid withdrawal leaves many questions unanswered—neither company publicly disclosed settlement terms or what changes Kalshi may have made to the markets. Limited information is available from Kalshi's perspective, as the company declined comment. The broader regulatory and safety debate around prediction markets on operational events remains unresolved despite the case dismissal.
