An individual made nearly half a million dollars by predicting the removal of the Venezuelan leader just before it was publicly declared, sparking debate about the possibility of profiting from non-public details of the US operation.

Changing Odds in Forecasts

Bets placed on the crypto-platform, a crypto-powered platform, that the Venezuelan president would be out of power by the close of the month rose in the period preceding Donald Trump declared on the weekend that Maduro had been taken into custody.

One account, which joined the platform recently and made four bets, all on Venezuela, made more than $436K from a modest bet of $32,537.

Who placed the bet is a mystery. The user had only a string of letters and numbers for identification.

Market Signals Before Announcement

Platform data shows that participants assessed the probability of Maduro's exit at just under 7% in the late afternoon of the Friday before the event.

But the market's assessment had increased to 11% by the end of the day and spiked dramatically in the morning of Saturday, suggesting a sharp shift in betting activity right before the public announcement was made.

"That trade has all the signs of a transaction based on non-public details," commented a financial reform advocate.

A small number of other platform users also made tens of thousands of dollars from similar wagers.

Legal Questions Grows

Politicians are starting to take note.

A new rule introduced on Monday seeks to ban federal workers from making trades on forecasting platforms if they have "insider details" related to a market.

Industry Context

Prediction markets have surged in popularity in recent years, with participants able to wager on everything from sports to politics.

Prediction markets were examined under the last presidential term. But it has found a more favorable environment during the current presidency.

Insider trading is against the law in the traditional financial markets, but there are less oversight in the forecasting arena.

A spokesperson for another major platform said their site "has clear rules against insider trading of any form."
