A trader profited close to $500,000 from wagers on the downfall of Nicolás Maduro just before it was publicly declared, raising questions about the possibility of profiting from confidential information of the event.

Sudden Shift in Predictions

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

A single trader, which registered on the site in December and made four bets, all on political events in Venezuela, earned over $436,000 from a starting bet of over $32,000.

It remains unclear. This unidentified trader had only a blockchain identifier for identification.

Probability Spikes Before Announcement

Market statistics shows that users estimated the likelihood of the president's removal at just 6.5% in the afternoon of the Friday before the event.

But the odds had increased to over 10% by the end of the day and spiked dramatically in the first hours of January 3rd, indicating a sharp shift in market sentiment immediately prior to the public announcement was made.

"This particular bet has all the hallmarks of a bet based on inside information," commented Dennis Kelleher.

A handful of other traders also profited significant sums from predicting the capture.

Legal Questions Emerges

Elected officials are beginning to pay attention.

Proposed legislation presented on the start of the week seeks to ban government employees from placing bets on prediction markets if they have "material nonpublic information" related to a market.

Market Background

Prediction markets have surged in popularity in recent years, with users able to wager on everything from elections to political events.

Prediction markets faced scrutiny under the last presidential term. Yet it has experienced less resistance during the present political climate.

Trading on insider information is against the law in the stock market, but there are more ambiguous rules in the prediction market space.

A spokesperson for Kalshi said their site "strictly forbids insider trading of any form."
