A trader earned a substantial sum on the ouster of Nicolás Maduro just before it was made public, raising questions about whether someone profited from inside knowledge of American actions.

Changing Odds in Forecasts

Predictions made on the forecasting site, a blockchain-based service, that Nicolás Maduro would be no longer in control by the end of January surged in the time leading up to Donald Trump announced on Saturday that the president had been seized.

A single trader, which registered on the site in December and made four bets, all on Venezuela, profited a total of $436,000 from a initial bet of $32,537.

It remains unclear. The anonymous account had only a string of letters and numbers for identification.

Probability Spikes Before News Break

Trading information shows that users assessed the probability of the president's removal at just 6.5% in the afternoon of Friday, January 2nd.

Yet these probabilities had climbed to 11% by the end of the day and skyrocketed in the morning of the next day, pointing to a rapid movement in market sentiment immediately prior to the social media post was made.

"That trade has all the signs of a trade based on non-public details," commented Dennis Kelleher.

A handful of other traders also made large payouts from similar wagers.

Regulatory Scrutiny Intensifies

Politicians are growing concerned.

A bill introduced on the start of the week aims to prohibit government employees from placing bets on prediction markets if they have "confidential government knowledge" related to a bet.

Market Background

Forecasting platforms have become increasingly popular in the United States, with users able to predict everything from sports outcomes to politics.

Prediction markets faced scrutiny under the last presidential term. However it has experienced less resistance during the Trump presidency.

Insider trading is illegal in the traditional financial markets, but there are less oversight in the event betting industry.

A company executive for a competing service said their site "strictly forbids trading on insider information of any form."
