FlightAware Drops Lawsuit Against Kalshi After One Day

Flight tracking firm FlightAware voluntarily dismissed its lawsuit against prediction market platform Kalshi a single day after filing it. The dismissal was made “without prejudice against all defendants,” according to Engadget.

What Happened

FlightAware, a flight tracking company, withdrew its lawsuit against Kalshi, a prediction market platform, one day after initiating legal proceedings, Reuters reported. The case was voluntarily dismissed “without prejudice against all defendants,” as confirmed by Engadget.

The initial lawsuit, filed earlier in the week, alleged that Kalshi was utilizing FlightAware’s flight data to operate a “gambling market.” Neither FlightAware nor Kalshi has publicly disclosed the specific reasons for the rapid withdrawal of the lawsuit, Engadget stated.

Key Details

• FlightAware voluntarily dismissed the lawsuit “without prejudice against all defendants,” according to Engadget.
• The dismissal occurred one day after the lawsuit was filed, Reuters reported.
• Kalshi reportedly altered its phrasing regarding flight cancellations, changing from “verified from FlightAware” to “verified from Primary Source Agency,” while still linking to FlightAware’s website, Reuters noted.
• Kalshi also added a disclaimer stating that its markets and products are not endorsed by the Primary Source Agency or its affiliates, and that references to the agency are descriptive only and do not imply endorsement or affiliation, according to Reuters.
• FlightAware’s original lawsuit included claims of reputational damage due to association with Kalshi and alleged violation of its terms of use for data utilization in what it termed a “gambling” context, Reuters stated.
• The state of New York reportedly filed a lawsuit against Kalshi in July 2026, alleging it was operating an “illegal gambling operation,” Reuters reported.

Why It Matters

This rapid legal development highlights potential tensions surrounding data usage and market classification within the prediction market sector. The initial lawsuit from FlightAware raised questions about the proprietary nature of flight data and its application in financial markets, particularly those that may be perceived as gambling operations by some jurisdictions.

The changes implemented by Kalshi in its presentation of flight cancellation verification, as noted by Reuters, indicate a potential response to concerns raised by data providers. The ongoing legal action by the state of New York against Kalshi further underscores the regulatory scrutiny faced by prediction market platforms regarding their operational classification and legality.
