FlightAware has voluntarily dismissed its lawsuit against prediction market platform Kalshi in a New York federal court. The legal filing, submitted just one day after the initial complaint, withdrew the case without prejudice. This legal status allows FlightAware to potentially refile the suit in the future.
The dispute centered on allegations that Kalshi used FlightAware’s proprietary data and trademark to settle bets on airline cancellations without permission. Kalshi had argued it relied on public government data and fair use principles. The dismissal comes as trading volumes for these specific aviation contracts remained a tiny fraction of Kalshi’s overall activity.
Key facts
- FlightAware filed the lawsuit on August 11, 2026, and dismissed it the next day on August 12, 2026.
- The complaint accused Kalshi of using private flight data and trademarks to facilitate betting markets.
- Kalshi defended its actions by citing nominative fair use and pointing to U.S. Department of Transportation data as an alternative source.
- Retail interest in the flight cancellation contracts was low, with only 31,412 contracts traded totaling $1.8 million in volume.
- The $1.8 million in aviation contract volume is small compared to Kalshi’s $148 billion in annual platform volume.
- The reasons for the sudden withdrawal are not publicly stated, and no private settlement terms have been disclosed.
Why it matters
This rapid resolution removes immediate legal uncertainty for Kalshi regarding its aviation betting products, though the door remains open for future litigation. It highlights the ongoing tension between traditional data providers and emerging prediction markets over intellectual property rights. For users and regulators, the low trading volume suggests this niche market has not yet gained significant traction despite the regulatory and legal attention it attracted.
