Question 1

Why did FlightAware sue Kalshi?

Accepted Answer

FlightAware alleged Kalshi used its flight data and trademark without permission to settle bets on airline cancellations, pleading breach of contract, trademark infringement under the Lanham Act and unfair competition, and it said the markets created safety risks.

Question 2

Why was the lawsuit dropped so quickly?

Accepted Answer

FlightAware filed a voluntary dismissal without prejudice a day after suing, and after Kalshi changed its market language; lawyer Ariel Givner said on X that such a fast exit after a TRO demand usually signals the parties settled privately.

Question 3

What other legal problems does Kalshi still face?

Accepted Answer

Kalshi is contesting state actions over its sports and event contracts, including a New York suit alleging illegal gambling and court moves in Washington and Michigan, while a Minnesota judge has let it keep operating during litigation there.
