FlightAware sues Kalshi over unauthorized flight data usage

The legal action asserts that Kalshi continued to display FlightAware’s branding and real-time information even after receiving formal demands to cease. According to the filing, the data provider remained unaware of the betting markets until they surfaced in media reports. FlightAware argues that transforming aviation performance into a gambling instrument creates severe safety risks, suggesting that market participants might manipulate flight operations to secure financial gains.

This confrontation highlights growing scrutiny over prediction platforms like Kalshi and Polymarket, where users wager on events ranging from political outcomes to commercial milestones. These platforms have faced criticism over potential insider trading and market manipulation, with past incidents involving significant payouts linked to geopolitical shifts and leaked presidential speech information. FlightAware is now seeking a jury trial to address the unauthorized usage and the potential threat to airport security, though the company has not yet specified a dollar amount for damages.
