A trader made nearly half a million dollars by predicting the removal of Venezuela's president shortly prior to it was officially announced, sparking debate about the possibility of profiting from confidential information of American actions.

Changing Odds in Forecasts

Wagers on Polymarket, an online prediction market, that Nicolás Maduro would be out of power by the end of January surged in the period preceding Donald Trump declared on January 3rd that Maduro had been apprehended.

A particular user, which joined the platform in December and placed four wagers, all on Venezuela, profited a total of $nearly half a million from a starting bet of $32.5K.

It remains unclear. This unidentified trader had only a string of letters and numbers for identification.

Odds Fluctuate Before Public Statement

Market statistics shows that traders assessed the probability of Maduro's exit at just 6.5% in the afternoon of the Friday before the event.

However the market's assessment had climbed to over 10% by the end of the day and surged in the early hours of January 3rd, indicating a sudden change in positions right before the official statement was made.

"This specific wager has all the characteristics of a trade based on inside information," said an industry expert.

Several of other traders also profited significant sums from bets on the same outcome.

Political Attention Emerges

Elected officials are starting to take note.

A new rule introduced on recently would prevent public officials from placing bets on prediction markets if they have "insider details" related to a bet.

Market Background

Event-driven betting sites have surged in popularity in the past few years, with traders able to wager on everything from elections to current affairs.

Prediction markets encountered regulatory challenges under the Biden administration. But it has experienced less resistance during the Trump presidency.

Insider trading is a crime in the traditional financial markets, but there are less oversight in the event betting arena.

A spokesperson for a competing service said their site "explicitly prohibits insider trading of any form."
