A bettor earned a substantial sum from wagers on the downfall of Venezuela's president just before it was publicly declared, sparking debate about potential gains made from confidential information of the event.

Sudden Shift in Wagers

Wagers on Polymarket, a blockchain-based service, that the Venezuelan president would be no longer in control by the close of the month increased in the hours before Donald Trump declared on Saturday that Maduro had been taken into custody.

A single trader, which registered on the site last month and made four bets, all on Venezuela, made more than $nearly half a million from a starting bet of $32,537.

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

Probability Spikes Before Announcement

Platform data shows that users put the odds of a political change at just 6.5% in the midday period of the prior Friday.

However these probabilities had increased to 11% by the end of the day and surged in the early hours of January 3rd, suggesting a rapid movement in betting activity immediately prior to the social media post was made.

"That trade has all the characteristics of a trade based on confidential knowledge," said a financial reform advocate.

Several of other traders also made significant sums from predicting the capture.

Political Attention Intensifies

Some lawmakers are beginning to pay attention.

A new rule put forward on Monday would prevent government employees from participating on forecasting platforms if they have "material nonpublic information" related to a wager.

Market Background

Event-driven betting sites have become increasingly popular in recent years, with participants able to bet on everything from sports outcomes to political events.

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

Using confidential knowledge is illegal in the stock market, but there are more ambiguous rules in the prediction market space.

An official representative for Kalshi said their site "has clear rules against such activities of any form."
