A trader profited close to $500,000 by predicting the removal of the Venezuelan leader immediately preceding it was made public, raising questions about whether someone profited from confidential information of the event.

Changing Odds in Predictions

Wagers on Polymarket, a crypto-powered platform, that the leader would be out of power by the end of January rose in the hours before Donald Trump announced on Saturday that the Venezuelan leader had been taken into custody.

One account, which became a member recently and placed four wagers, all on political events in Venezuela, made more than $436K from a modest bet of $32,537.

The identity is unknown. The anonymous account had only a blockchain identifier for identification.

Odds Fluctuate Before Public Statement

Platform data shows that participants estimated the likelihood of a political change at just a low 6.5 percent in the midday period of the prior Friday.

Yet the market's assessment had increased to 11% by shortly before midnight and surged in the first hours of the next day, suggesting a rapid movement in positions just before the public announcement was made.

"This specific wager has all the hallmarks of a trade based on confidential knowledge," said a financial reform advocate.

A small number of other traders also made tens of thousands of dollars from predicting the capture.

Legal Questions Emerges

Elected officials are beginning to pay attention.

A bill presented on the start of the week would prevent public officials from making trades on forecasting platforms if they have "confidential government knowledge" related to a wager.

Industry Context

Event-driven betting sites have surged in popularity in the past few years, with participants able to wager on everything from sports outcomes to political events.

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

Trading on insider information is illegal in the traditional financial markets, but there are more ambiguous rules in the forecasting space.

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