FlightAware Sues Kalshi Over Flight Data

The update

FlightAware has filed a lawsuit against prediction market platform Kalshi in a New York federal court, alleging the company used its flight data and trademark without permission to settle betting contracts on flight cancellations. The complaint cites trademark infringement, breach of contract, injury to reputation, and unfair competition. FlightAware claims Kalshi ignored a cease-and-desist letter and continued to reference its data for settling contracts even after adding a disclaimer that the markets were not endorsed.

Why it matters

This legal dispute highlights the growing tension between traditional data providers and emerging prediction markets. FlightAware claims Kalshi’s use of its data and branding associates the flight tracking company with activities that could harm its reputation, particularly as authorities increasingly question whether prediction markets constitute illegal gambling. The case could set a precedent for whether prediction platforms can use third-party data and branding without commercial agreements.

What to watch

How this case might impact Kalshi’s regulatory standing as it already faces legal challenges from New York, Wisconsin, and Nevada over alleged unlicensed gambling activities. The outcome could influence how prediction markets rely on third-party data and branding, potentially affecting public safety concerns regarding markets that incentivize unsafe tactics to impact flight cancellations.
