The lawsuit cited authorities’ claims that event contracts on prediction market platforms like Kalshi were “wagers” in violation of state laws, adding that the company’s expansion to trading on commercial flights starting in July was associating FlightAware with activities potentially harming its reputation. FlightAware sought to “stop Kalshi’s illicit behavior before there is any harm to public safety.”“[T]here was widespread outrage and concern that the markets would incentivize unsafe tactics to impact cancellations, threatening public safety and creating the potential for massive disruption of air travel. Airlines condemned the markets,” said the lawsuit. “And due to Kalshi’s unauthorized use of FlightAware’s data and mark, customers immediately assumed that FlightAware was involved in the scheme.”Example of flight cancellation event contract citing FlightAware data.
