The settlement-oracle problem is now a courtroom problem

Every regulated U.S. event-betting contract needs a tiebreaker, a place where "the outcome" is declared final. Prediction markets have spent the last year pretending that place is their own rules engine. It isn't. It's whatever dataset settles the question, and the owner of that dataset just got handed the bill.

FlightAware's complaint against Kalshi, filed this week, makes that explicit. Kalshi began running flight-cancellation markets roughly a month ago, displaying FlightAware's name on the page, without a data license and without ever telling the flight tracker that its cancellation feeds would resolve real money. FlightAware says it only learned the markets existed when reporters called. The branded page kept running after a stop-and-desist demand.

The frame is bigger than trademark. A prediction market that resolves off an unlicensed third-party feed has, in effect, turned that feed's owner into the de facto settlement oracle — the reporter's interpretive inference from the complaint's allegations, not a stated cause of action — while the data owner absorbs the manipulation risk it never agreed to carry. FlightAware points to other prediction-market cases as illustrations of that exposure: a $32,000 Polymarket bet returning $400,000 on a Maduro outcome, and a Kalshi trader allegedly making over $100,000 using White House teleprompter advance knowledge. Aviation just makes the cost legible: a market that pays on grounded flights pays someone to ground one. The data license is the only chokepoint where that risk can be repriced before settlement, and right now there isn't one.
