A bettor earned a substantial sum by predicting the removal of the Venezuelan leader just before it was publicly declared, leading to inquiries about the possibility of profiting from inside knowledge of the US operation.
Predictions made on the forecasting site, a blockchain-based service, that the leader would be no longer in control by the close of the month increased in the time leading up to Donald Trump stated on the weekend that Maduro had been seized.
A single trader, which registered on the site last month and made four bets, all on political events in Venezuela, profited a total of $436K from a starting bet of $32,537.
The identity is unknown. The anonymous account had only a cryptographic address for identification.
Market statistics shows that traders put the odds of Maduro's exit at just a low 6.5 percent in the midday period of the Friday before the event.
But these probabilities had jumped to eleven percent by shortly before midnight and skyrocketed in the morning of Saturday, suggesting a sudden change in betting activity just before the public announcement was made.
"This specific wager has all the hallmarks of a trade based on inside information," stated an industry expert.
A handful of other platform users also profited large payouts from predicting the capture.
Politicians are growing concerned.
A bill put forward on the start of the week aims to prohibit federal workers from making trades on forecasting platforms if they have "material nonpublic information" related to a market.
Forecasting platforms have surged in popularity in the United States, with traders able to predict everything from elections to current affairs.
This sector encountered regulatory challenges under the previous administration. Yet it has received a warmer welcome during the current presidency.
Trading on insider information is against the law in the traditional financial markets, but there are more ambiguous rules in the event betting space.
A company executive for a competing service said their site "has clear rules against trading on insider information of any form."
