A bettor profited close to $500,000 from wagers on the downfall of Venezuela's president immediately preceding it was made public, leading to inquiries about whether someone profited from confidential information of the US operation.
Wagers on Polymarket, a blockchain-based service, that the leader would be removed from office by the end of January rose in the period preceding Donald Trump announced on January 3rd that the Venezuelan leader had been seized.

The identity is unknown. The anonymous account had only a blockchain identifier for identification.
Trading information shows that participants estimated the likelihood of the president's removal at just a low 6.5 percent in the late afternoon of Friday, January 2nd.
But the market's assessment had jumped to eleven percent by shortly before midnight and skyrocketed in the morning of the next day, indicating a rapid movement in market sentiment just before the social media post was made.
