Aviation data provider FlightAware has withdrawn a lawsuit against prediction market platform Kalshi just one day after filing it, in a swift reversal that saw the trading platform quietly adjust how it sources data for at least one of its event contracts.
A Lawsuit With a Short Shelf Life
The legal dispute between FlightAware and Kalshi lasted barely 24 hours before the aviation data company moved to drop its claims. The rapid retreat suggests the two parties may have reached some form of resolution behind the scenes, though the exact terms of any agreement have not been made public.
The original complaint centered on how Kalshi was using flight-related information to power its prediction market contracts, which allow users to wager on real-world outcomes such as whether specific flights would be cancelled.
A lawsuit that vanishes in a single day tends to signal a quiet deal rather than a courtroom victory.
Kalshi Shifts Its Data Attribution
In the wake of the initial filing, at least one of Kalshi's event contracts was updated to reflect a change in how flight cancellation data is verified. The contract now lists "Primary Source Agency" as the entity responsible for confirming the underlying information.
The adjustment points to Kalshi moving away from relying on FlightAware's data feed, at least for the affected markets. Prediction platforms depend heavily on reliable, authoritative sources to settle contracts, making data attribution a sensitive issue.
Kalshi has been aggressively expanding its lineup of event contracts, drawing attention from regulators and data providers alike as it ventures into new categories of real-world outcomes.
- The lawsuit was filed and dropped within a single day.
- Kalshi changed the data verification source on at least one contract.
- The new attribution reads "Primary Source Agency."
The episode underscores the legal and operational challenges facing prediction markets as they scale, particularly when their contracts hinge on third-party data that may come with its own usage restrictions.
