History

Historical Context

Intrade, founded in 1999, halted operations after a 2012 CFTC suit and a 10 March 2013 suspension of all trading. The indictment of Master Sergeant Gannon Van Dyke for using classified raid details to bet on Polymarket mirrors that earlier regulatory clash, prompting the DOJ and CFTC to consider tighter oversight of prediction markets.
