Prediction markets turn real-world events into tradable contracts — and data is the fuel that powers them. A flight tracking service has now sued Kalshi, one of the most prominent regulated prediction platforms, over the alleged use of its data without authorization. The lawsuit, still thin on public details, could change how prediction platforms source and license the information behind their markets. Here is what we know — and what is still open.

A legal fight over flight information
At the centre of the dispute is a direct claim: a flight tracking service provided data, and Kalshi used it without permission. The service has taken legal action over that use. Exactly which Kalshi contracts may have relied on the data, and what terms were allegedly crossed, have not been made public in the available reporting.
Why flight data is worth going to court over
Flight tracking data is expensive to produce. It depends on networks of sensors, satellite feeds, and aviation inputs, cleaned and delivered in near real time. For a prediction market, such data can support contracts tied to flight delays, airport disruptions, or travel outcomes. For the tracking service, it is the core product. When that data is used without a license, the owner loses both revenue and control.
Kalshi's position in the prediction market world
Kalshi operates federally regulated event contracts, allowing users to trade on the outcome of real-world questions. Its status as one of the only CFTC-regulated prediction markets in the US makes it a significant player. That also gives this lawsuit symbolic weight — a direct challenge to how a major, regulated platform sources the information behind its offerings.
