A Prediction Market User Earned $436,000 from Bets on Venezuela's Political Shift.

A bettor profited close to $500,000 on the ouster of Venezuela's president immediately preceding it was made public, raising questions about whether someone profited from non-public details of the US operation.

Changing Odds in Predictions

Predictions made on the forecasting site, an online prediction market, that Nicolás Maduro would be out of power by the month's conclusion increased in the hours before Donald Trump announced on Saturday that the president had been taken into custody.

A particular user, which joined the platform last month and placed four wagers, all on Venezuela, profited a total of $nearly half a million from a starting bet of over $32,000.

The identity is unknown. The anonymous account had only a string of letters and numbers for identification.

Probability Spikes Before Announcement

Platform data shows that users assessed the probability of the president's removal at just 6.5% in the late afternoon of the Friday before the event.

Yet the odds had jumped to eleven percent by shortly before midnight and surged in the first hours of the next day, pointing to a sudden change in positions just before the official statement was made.

"This particular bet has all the characteristics of a trade based on inside information," commented a financial reform advocate.

Several of other traders also made large payouts from bets on the same outcome.

Legal Questions Emerges

Politicians are growing concerned.

A bill put forward on Monday would prevent public officials from making trades on prediction markets if they have "confidential government knowledge" related to a bet.
