A trader made nearly half a million dollars by predicting the removal of Nicolás Maduro immediately preceding it was made public, raising questions about potential gains made from inside knowledge of the event.

Sudden Shift in Forecasts

Predictions made on the forecasting site, a blockchain-based service, that the Venezuelan president would be removed from office by the close of the month increased in the time leading up to former President Trump declared on the weekend that the president had been seized.

A single trader, which joined the platform last month and took four positions, all on political events in Venezuela, earned over $436K from a starting bet of $32,537.

Who placed the bet is a mystery. The user had only a blockchain identifier for identification.

Probability Spikes Before Public Statement

Market statistics shows that users estimated the likelihood of Maduro's exit at just 6.5% in the late afternoon of the prior Friday.

Yet these probabilities had climbed to eleven percent by late Friday night and surged in the first hours of Saturday, suggesting a sharp shift in positions right before the social media post was made.

"This particular bet has all the characteristics of a transaction based on confidential knowledge," said Dennis Kelleher.

A small number of other traders also earned tens of thousands of dollars from bets on the same outcome.

Regulatory Scrutiny Intensifies

Some lawmakers are beginning to pay attention.

A bill introduced on the start of the week would prevent public officials from placing bets on prediction markets if they have "confidential government knowledge" related to a market.

Market Background

Event-driven betting sites have become increasingly popular in the United States, with participants able to predict everything from elections to politics.

The industry encountered regulatory challenges under the last presidential term. Yet it has experienced less resistance during the current presidency.

Insider trading is a crime in the securities markets, but there are more ambiguous rules in the event betting industry.

A spokesperson for Kalshi said their site "strictly forbids such activities of any form."
