The complaint, filed Monday, centers on markets Kalshi launched last month that allowed users to trade contracts based on whether flights would be canceled. FlightAware also argued that prediction markets tied to flight cancellations could create incentives for participants to interfere with airline operations. A judge there blocked enforcement of a new state law banning prediction markets, allowing Kalshi and Polymarket to continue operating while litigation proceeds. At the same time, the Commodity Futures Trading Commission has sued several states as part of an effort to establish federal authority over prediction markets. That combination of federal-state disputes and private litigation could slow product expansion across the prediction market sector.
