A trader made nearly half a million dollars from wagers on the downfall of the Venezuelan leader shortly prior to it was officially announced, leading to inquiries about potential gains made from non-public details of American actions.

Sudden Shift in Predictions

Wagers on Polymarket, a crypto-powered platform, that Nicolás Maduro would be no longer in control by the close of the month surged in the hours before former President Trump declared on the weekend that Maduro had been taken into custody.

A single trader, which joined the platform recently and placed four wagers, all on Venezuela, earned over $nearly half a million from a modest bet of $32,537.

The identity is unknown. This unidentified trader had only a string of letters and numbers for identification.

Probability Spikes Before Announcement

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

But the odds had jumped to 11% by late Friday night and skyrocketed in the morning of the next day, pointing to a sudden change in betting activity immediately prior to the public announcement was made.

"That trade has all the characteristics of a bet based on non-public details," commented Dennis Kelleher.

A small number of other traders also earned large payouts from bets on the same outcome.

Regulatory Scrutiny Intensifies

Elected officials are beginning to pay attention.

A new rule put forward on the start of the week seeks to ban government employees from participating on prediction markets if they have "material nonpublic information" related to a market.

Market Background

Event-driven betting sites have surged in popularity in recent years, with participants able to wager on everything from sports to current affairs.

The industry faced scrutiny under the previous administration. However it has found a more favorable environment during the current presidency.

Trading on insider information is a crime in the stock market, but there are less oversight in the prediction market industry.

A spokesperson for a competing service said their site "has clear rules against insider trading of any form."
