An Prediction Market Participant Made $Nearly Half a Million on Bets Predicting the Ouster of Maduro.

An individual made nearly half a million dollars by predicting the removal of Venezuela's president immediately preceding it was officially announced, leading to inquiries about potential gains made from confidential information of the US operation.

Changing Odds in Forecasts

Wagers on Polymarket, an online prediction market, that the Venezuelan president would be removed from office by the month's conclusion rose in the period preceding President Donald Trump declared on Saturday that Maduro had been apprehended.

A single trader, which registered on the site recently and made four bets, all on Venezuela, earned over $436K from a starting bet of $32.5K.

Who placed the bet is a mystery. The user had only a blockchain identifier for identification.

Probability Spikes Before Public Statement

Trading information shows that traders put the odds of a political change at just under 7% in the afternoon of the Friday before the event.

But these probabilities had increased to 11% by shortly before midnight and surged in the morning of January 3rd, suggesting a rapid movement in positions immediately prior to the official statement was made.

"This particular bet has all the signs of a bet based on non-public details," commented a financial reform advocate.

A handful of other individuals also made tens of thousands of dollars from bets on the same outcome.

Regulatory Scrutiny Grows

Some lawmakers are growing concerned.

A bill put forward on the start of the week aims to prohibit federal workers from making trades on forecasting platforms if they have "insider details" related to a market.

The Prediction Market Landscape

Event-driven betting sites have grown significantly in the United States, with users able to predict everything from sports outcomes to political events.

Prediction markets encountered regulatory challenges under the Biden administration. But it has found a more favorable environment during the present political climate.

Trading on insider information is a crime in the stock market, but there are less oversight in the event betting space.

A company executive for another major platform said their site "explicitly prohibits insider trading of any form."
