A trader earned a substantial sum by predicting the removal of Venezuela's president just before it was made public, raising questions about whether someone profited from non-public details of the event.

Market Movement in Forecasts

Wagers on Polymarket, an online prediction market, that the Venezuelan president would be no longer in control by the month's conclusion increased in the period preceding Donald Trump declared on Saturday that the president had been seized.

One account, which joined the platform in December and placed four wagers, all on the Venezuelan situation, earned over $436,000 from a starting bet of $32.5K.

Who placed the bet is a mystery. This unidentified trader had only a cryptographic address for identification.

Probability Spikes Before Announcement

Market statistics shows that participants put the odds of Maduro's exit at just 6.5% in the midday period of Friday, January 2nd.

Yet these probabilities had jumped to over 10% by shortly before midnight and spiked dramatically in the morning of Saturday, indicating a sharp shift in betting activity right before the public announcement was made.

"This specific wager has all the characteristics of a transaction based on inside information," said an industry expert.

Several of other traders also made large payouts from similar wagers.

Political Attention Grows

Politicians are beginning to pay attention.

A bill presented on Monday aims to prohibit public officials from making trades on forecasting platforms if they have "confidential government knowledge" related to a market.

Industry Context

Prediction markets have become increasingly popular in the past few years, with participants able to predict everything from sports to current affairs.

Prediction markets encountered regulatory challenges under the Biden administration. But it has found a more favorable environment during the Trump presidency.

Insider trading is a crime in the stock market, but there are fewer regulations in the event betting space.

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