Aug 12 (Reuters) – Flight-tracking company FlightAware withdrew its lawsuit against Kalshi on Tuesday, a day after it filed the suit that ​accuses the prediction markets giant of ‌using its data and name without its knowledge to host gambling markets on flight cancellations.

Here are some details:

• The case has been “voluntarily dismissed, without prejudice, against all defendants,” ‌lawyers ​for FlightAware wrote in ⁠the latest filing.

• Neither ⁠company immediately responded to Reuters’ requests for further comment.

• The U.S. flight cancellation contract for the week ending August 14 remained available on ​Kalshi’s website, although it no longer named FlightAware as the source.

• The disclaimer on ⁠Kalshi’s flight cancellation contract page ⁠reads “outcome verified from Primary Source Agency,” ​which links to FlightAware’s website. Earlier it said the ​outcome was verified “from Flight Aware”.

• Kalshi’s disclaimer says: “This ‌market and these products have not been endorsed by the Primary Source Agency or its affiliates. Any references to the Primary Source Agency’s ⁠delay and cancellation page, or any associated marks are descriptive only and do not indicate an endorsement of ⁠this product ‌or any affiliation between the ⁠Primary Source Agency or its affiliates ​and Kalshi.”

• ‌FlightAware was seeking unspecified damages ​as well ⁠as court orders barring Kalshi from using its data when it filed the lawsuit in the U.S. District Court for the Southern District of New York.
