A Prediction Market Trader Earned $Nearly Half a Million from Wagers on Venezuela's Political Shift.

A bettor profited close to $500,000 by predicting the removal of the Venezuelan leader just before it was publicly declared, sparking debate about the possibility of profiting from confidential information of American actions.

Who placed the bet is a mystery. The anonymous account had only a cryptographic address for identification.

Probability Spikes Before Public Statement
