Intrade shutdown (2013)
Intrade, an Irish prediction market, sold event contracts on elections, sports and awards to global users. In 2012 the U.S. Commodity Futures Trading Commission charged it with selling unregistered commodity options to American customers.
Intrade halted U.S. trading, froze customer withdrawals and shut down by 2013.
The case showed prediction markets could be ended by regulatory action even without a formal product ban.
CME's wind-down is voluntary, not ordered, but it shows the same underlying fragility: event contracts sit at the boundary of derivatives and wagering, and regulators or courts can move the line.
