Forced to shutter its U.S. unit last November, once popular online trading exchange company Intrade ceased all of its operations this week amid an investigation into its business practices.

The latest development comes a little more than a year after Winston & Strawn, which had been representing Intrade in the U.S., cut ties with the company, which allowed users to place bets on such non-sporting events as the rise and fall of financial markets, the weather, Academy Award winners, U.S. Supreme Court decisions, presidential elections, and even the selection of a new pope.
