FlightAware voluntarily dismissed without prejudice its lawsuit against Kalshi a day after suing the prediction market operator over alleged unauthorized use of its name and data in flight-cancellation contracts. A Tuesday filing in the U.S. District Court for the Southern District of New York ended the case after FlightAware had accused Kalshi of using its data and branding to run what it described as gambling markets on flight cancellations. On the same day, a judge had ordered Kalshi to show cause why a temporary restraining order should not be issued over FlightAware's trademark and data claims. At least one Kalshi event contract was revised after the lawsuit was filed, changing the verification source from "FlightAware" to "Primary Source Agency" and adding language stating that the reference did not indicate endorsement or affiliation. The Primary Source Agency link directed users to FlightAware's website. Neither company had publicly commented on the dismissal as of Wednesday, leaving open the possibility of a private resolution while preserving FlightAware's ability to refile. The dispute came as Kalshi, Polymarket and other prediction market operators face pressure from U.S. state gaming regulators over contracts tied to sports and other events. The CFTC said Tuesday it had invoked "emergency authority" to block New York officials from seeking a temporary restraining order that would bar Kalshi from offering event contracts nationwide, underscoring the ongoing conflict between federal oversight claims and state gambling enforcement.
