A bettor earned a substantial sum on the ouster of Nicolás Maduro immediately preceding it was officially announced, raising questions about whether someone profited from confidential information of the event.

Changing Odds in Forecasts

Bets placed on the crypto-platform, an online prediction market, that Nicolás Maduro would be no longer in control by the close of the month rose in the period preceding President Donald Trump announced on Saturday that the president had been taken into custody.

A single trader, which became a member in December and made four bets, all on political events in Venezuela, profited a total of $436K from a modest bet of over $32,000.

The identity is unknown. The anonymous account had only a cryptographic address for identification.

Market Signals Before Announcement

Trading information shows that traders assessed the probability of a political change at just 6.5% in the late afternoon of the prior Friday.

But the market's assessment had increased to 11% by shortly before midnight and surged in the early hours of January 3rd, suggesting a sudden change in positions right before the official statement was made.

"This specific wager has all the signs of a bet based on confidential knowledge," commented a financial reform advocate.

A small number of other platform users also earned significant sums from similar wagers.

Legal Questions Intensifies

Elected officials are growing concerned.

A new rule introduced on the start of the week would prevent government employees from participating on prediction markets if they have "confidential government knowledge" related to a bet.

Industry Context

Event-driven betting sites have surged in popularity in recent years, with participants able to bet on everything from elections to politics.

This sector encountered regulatory challenges under the previous administration. But it has received a warmer welcome during the present political climate.

Insider trading is against the law in the traditional financial markets, but there are fewer regulations in the event betting industry.

A spokesperson for Kalshi said their site "strictly forbids insider trading of any form."
