FlightAware, a flight tracking data provider, filed a lawsuit against Kalshi, the prediction market platform, and dropped it the very next day. The quick withdrawal came after at least one of Kalshi's event contracts was changed to list 'Primary Source Agency' as the entity responsible for verifying flight cancellation data.
A one-day lawsuit
The lawsuit was filed and then withdrawn within 24 hours. No details of the complaint have been made public, and neither company has released a statement explaining the reversal. The filing itself was not available for review, leaving the specific claims unclear.
What is clear is the timing. The contract change happened after the lawsuit was filed, and the lawsuit was dropped after that change. The sequence suggests the two events are linked, though neither company has confirmed that.
The contract's new wording
At least one of Kalshi's event contracts now names 'Primary Source Agency' as the entity behind verifying flight cancellation data. That wording is a shift from how the contract previously described the verification process, though the earlier language has not been disclosed.
The change means the contract now explicitly identifies the agency responsible for confirming whether flights are canceled. That detail matters because Kalshi's event contracts allow users to trade on outcomes like flight cancellations, and the verification source is central to how those contracts settle.
FlightAware's role in the flight data ecosystem is well established, but the company's connection to this specific contract is not spelled out in the available facts. The lawsuit's withdrawal leaves the contract change as the only visible outcome of the dispute.
Neither company has said whether the contract will be revised further or if any other contracts are affected. The revised contract is now in place, and the lawsuit is no longer active. It's unclear whether any further legal action is planned.
