A trader earned a substantial sum on the ouster of Nicolás Maduro immediately preceding it was publicly declared, leading to inquiries about whether someone profited from inside knowledge of American actions.
Predictions made on the forecasting site, a blockchain-based service, that Nicolás Maduro would be removed from office by the end of January rose in the time leading up to Donald Trump announced on Saturday that Maduro had been apprehended.
A particular user, which registered on the site in December and placed four wagers, all on Venezuela, made more than $436K from a initial bet of $32,537.
It remains unclear. The user had only a cryptographic address for identification.
Trading information shows that participants assessed the probability of Maduro's exit at just under 7% in the midday period of the prior Friday.
But the odds had climbed to eleven percent by late Friday night and skyrocketed in the morning of the next day, suggesting a sharp shift in betting activity immediately prior to the public announcement was made.
"This particular bet has all the signs of a transaction based on inside information," said a financial reform advocate.
Several of other individuals also profited significant sums from similar wagers.
Some lawmakers are starting to take note.
A new rule presented on recently seeks to ban federal workers from making trades on forecasting platforms if they have "material nonpublic information" related to a wager.
Forecasting platforms have become increasingly popular in the United States, with users able to bet on everything from sports to political events.
Prediction markets faced scrutiny under the last presidential term. However it has found a more favorable environment during the Trump presidency.
Insider trading is against the law in the stock market, but there are fewer regulations in the event betting industry.
An official representative for a competing service said their site "has clear rules against such activities of any form."
