A bettor made nearly half a million dollars from wagers on the downfall of Nicolás Maduro just before it was officially announced, leading to inquiries about potential gains made from confidential information of the event.

Changing Odds in Forecasts

Bets placed on the crypto-platform, an online prediction market, that the Venezuelan president would be removed from office by the close of the month rose in the time leading up to Donald Trump announced on January 3rd that the president had been seized.

A particular user, which joined the platform last month and made four bets, all on Venezuela, profited a total of $436K from a modest bet of $32,537.

The identity is unknown. This unidentified trader had only a cryptographic address for identification.

Probability Spikes Before News Break

Trading information shows that traders assessed the probability of the president's removal at just under 7% in the afternoon of the Friday before the event.

However these probabilities had increased to over 10% by the end of the day and surged in the morning of Saturday, indicating a rapid movement in betting activity right before the public announcement was made.

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

A handful of other traders also made large payouts from bets on the same outcome.

Legal Questions Intensifies

Some lawmakers are starting to take note.

A bill put forward on recently seeks to ban federal workers from making trades on forecasting platforms if they have "material nonpublic information" related to a market.

The Prediction Market Landscape

Prediction markets have grown significantly in the past few years, with participants able to bet on everything from elections to current affairs.

This sector faced scrutiny under the last presidential term. Yet it has found a more favorable environment during the Trump presidency.

Using confidential knowledge is a crime in the securities markets, but there are fewer regulations in the forecasting space.

An official representative for Kalshi said their site "explicitly prohibits insider trading of any form."
