A trader made nearly half a million dollars on the ouster of the Venezuelan leader just before it was publicly declared, leading to inquiries about potential gains made from non-public details of the US operation.

Changing Odds in Forecasts

Wagers on Polymarket, an online prediction market, that Nicolás Maduro would be out of power by the month's conclusion surged in the hours before President Donald Trump declared on the weekend that the Venezuelan leader had been taken into custody.

A particular user, which became a member last month and made four bets, all on political events in Venezuela, profited a total of $nearly half a million from a modest bet of $32,537.

The identity is unknown. This unidentified trader had only a cryptographic address for identification.

Odds Fluctuate Before Announcement

Platform data shows that traders estimated the likelihood of Maduro's exit at just a low 6.5 percent in the late afternoon of the Friday before the event.

Yet the market's assessment had increased to 11% by the end of the day and spiked dramatically in the early hours of January 3rd, suggesting a rapid movement in positions immediately prior to the public announcement was made.

"This specific wager has all the characteristics of a transaction based on confidential knowledge," commented Dennis Kelleher.

A small number of other individuals also profited tens of thousands of dollars from bets on the same outcome.

Regulatory Scrutiny Emerges

Elected officials are beginning to pay attention.

A bill put forward on recently seeks to ban public officials from making trades on prediction markets if they have "insider details" related to a bet.

Market Background

Forecasting platforms have surged in popularity in the United States, with users able to wager on everything from elections to politics.

The industry encountered regulatory challenges under the previous administration. But it has experienced less resistance during the Trump presidency.

Using confidential knowledge is against the law in the stock market, but there are less oversight in the event betting industry.

An official representative for another major platform said their site "has clear rules against insider trading of any form."
