An individual made nearly half a million dollars from wagers on the downfall of Venezuela's president just before it was made public, raising questions about the possibility of profiting from inside knowledge of the US operation.

Sudden Shift in Predictions

Predictions made on the forecasting site, a blockchain-based service, that the leader would be no longer in control by the month's conclusion rose in the period preceding Donald Trump announced on January 3rd that Maduro had been seized.

A single trader, which joined the platform last month and placed four wagers, all on Venezuela, made more than $436,000 from a modest bet of over $32,000.

The identity is unknown. The user had only a cryptographic address for identification.

Probability Spikes Before Announcement

Platform data shows that users assessed the probability of a political change at just under 7% in the afternoon of the prior Friday.

Yet these probabilities had climbed to over 10% by the end of the day and surged in the morning of January 3rd, pointing to a sharp shift in market sentiment immediately prior to the official statement was made.

"This specific wager has all the characteristics of a trade based on non-public details," said Dennis Kelleher.

A handful of other traders also profited tens of thousands of dollars from bets on the same outcome.

Regulatory Scrutiny Intensifies

Elected officials are starting to take note.

A new rule introduced on Monday would prevent federal workers from participating on forecasting platforms if they have "insider details" related to a wager.

Industry Context

Forecasting platforms have grown significantly in recent years, with users able to predict everything from elections to politics.

This sector were examined under the previous administration. However it has found a more favorable environment during the Trump presidency.

Using confidential knowledge is a crime in the securities markets, but there are fewer regulations in the prediction market arena.

A company executive for Kalshi said their site "strictly forbids such activities of any form."
