FlightAware has withdrawn its lawsuit against prediction-market platform Kalshi, ending a brief legal dispute over allegations that the trading venue used the aviation data firm’s information without authorization to power betting markets on flight cancellations.
The flight-tracking company had accused Kalshi of scraping and repackaging its proprietary data to create contracts allowing users to wager on whether specific flights would be canceled or delayed. The suit contended that such use violated FlightAware’s terms of service and intellectual property rights.
Kalshi operates as a federally regulated exchange offering event contracts, letting traders take positions on real-world outcomes ranging from economic indicators to weather and, more recently, air-travel disruptions. The company has expanded aggressively into new categories after clearing a series of regulatory hurdles.
The rapid reversal leaves several questions unresolved. Court filings did not detail whether the two firms reached a settlement, a licensing arrangement, or whether FlightAware simply opted to abandon the claim. Neither party disclosed financial terms.
The episode underscores the friction emerging as prediction markets push into data-intensive territory. Betting on flight cancellations relies on granular, real-time information, and data providers have grown increasingly protective of feeds that can be monetized by third parties.
Kalshi has faced mounting scrutiny on multiple fronts as it broadens its offerings. The platform is contending with a New York action alleging its contracts amount to illegal gambling, part of a wider debate over how event-based trading should be regulated.
The company secured a significant win in 2024 when the Commodity Futures Trading Commission dropped an appeal that had blocked its election-related contracts, opening the door to a rapid expansion of its markets.
Data-licensing disputes have become a recurring theme across technology and finance, as companies that aggregate real-time information seek to control how it is reused by downstream platforms building consumer-facing products.
For now, the withdrawal removes one legal cloud over Kalshi’s aviation markets, though it offers little clarity on how the platform will source its underlying data going forward. Whether the two companies have reached a durable understanding, or merely postponed a confrontation, remains unclear.
