A trader profited close to $500,000 by predicting the removal of Venezuela's president immediately preceding it was made public, raising questions about the possibility of profiting from confidential information of the event.

A single trader, which joined the platform last month and placed four wagers, all on Venezuela, made more than $436,000 from a initial bet of $32,537.
The identity is unknown. The anonymous account had only a cryptographic address for identification.
Trading information shows that participants assessed the probability of Maduro's exit at just 6.5% in the midday period of Friday, January 2nd.
However the odds had climbed to eleven percent by late Friday night and surged in the morning of Saturday, pointing to a rapid movement in positions immediately prior to the public announcement was made.
"This specific wager has all the signs of a bet based on inside information," said a financial reform advocate.
A small number of other platform users also earned significant sums from similar wagers.
Some lawmakers are beginning to pay attention.
Proposed legislation introduced on Monday seeks to ban public officials from participating on forecasting platforms if they have "material nonpublic information" related to a wager.
Prediction markets have surged in popularity in recent years, with users able to bet on everything from sports outcomes to politics.
