A bettor profited close to $500,000 by predicting the removal of Venezuela's president just before it was officially announced, sparking debate about the possibility of profiting from confidential information of the event.

Changing Odds in Predictions

Predictions made on the forecasting site, an online prediction market, that the Venezuelan president would be out of power by the end of January increased in the time leading up to President Donald Trump announced on January 3rd that Maduro had been taken into custody.

One account, which became a member in December and took four positions, all on the Venezuelan situation, made more than $436,000 from a starting bet of over $32,000.

The identity is unknown. The user had only a string of letters and numbers for identification.

Probability Spikes Before News Break

Market statistics shows that users put the odds of the president's removal at just under 7% in the late afternoon of the Friday before the event.

Yet the odds had climbed to over 10% by shortly before midnight and surged in the early hours of January 3rd, pointing to a sharp shift in market sentiment right before the public announcement was made.

"That trade has all the characteristics of a bet based on confidential knowledge," commented an industry expert.

A handful of other platform users also made significant sums from predicting the capture.

Regulatory Scrutiny Grows

Politicians are growing concerned.

A new rule presented on Monday seeks to ban government employees from making trades on forecasting platforms if they have "insider details" related to a bet.

Market Background

Event-driven betting sites have grown significantly in recent years, with traders able to wager on everything from elections to current affairs.

Prediction markets faced scrutiny under the Biden administration. However it has experienced less resistance during the current presidency.

Insider trading is illegal in the traditional financial markets, but there are fewer regulations in the forecasting space.

A spokesperson for Kalshi said their site "has clear rules against trading on insider information of any form."
