Polymarket faces insider-trading fears as ‘Maduro trade’ shakes prediction markets

A suspected insider’s ‘Maduro trade’ and fresh Iran bets on Polymarket fuel fears of “information laundering” and prompt a bill to ban U.S. officials from trading.

Polymarket, a blockchain-based prediction marketplace platform, faces mounting scrutiny over allegations of insider trading and concerns that the platform may be used to manipulate information and influence public sentiment, according to recent market activity and regulatory developments.

Polymarket under fire for a controversial ‘Maduro Trade’

The controversy centers on what market observers have termed the “Maduro trade.” Earlier this month, an anonymous wallet generated substantial profits after betting on the removal of Venezuelan President Nicolás Maduro hours before U.S. special forces captured him, according to blockchain transaction data.

President Donald Trump publicly stated that a Venezuelan whistleblower connected to the operation had been arrested, adding political dimensions to the case.

Data from Lookonchain, a blockchain analytics service, indicated that two of three wallets linked to those profits remained inactive for 11 days, prompting speculation about potential law enforcement or exchange involvement. A third wallet has resumed activity, according to the data.

The active wallet placed a bet two days ago predicting that Iran’s Supreme Leader, Ayatollah Ali Khamenei, will lose power by Jan. 31, as domestic protests continue in Iran. The market remains open and under observation, according to Polymarket data.

Additional suspicious activity emerged this week when another large wallet invested heavily in the possibility of a U.S. attack on Iran by Jan. 14. During the escalation of protests and temporary closure of Iranian airspace, odds on Polymarket surged and trading volume increased, according to platform data.

The attack did not occur, and the market closed with a “No” result, eliminating the trader’s position. However, the trading activity generated significant attention in global markets, according to market analysts.

Analysts have identified what they describe as “information laundering,” a tactic involving large bets designed to shift market odds. Trading bots and social media platforms amplify these movements, presenting them as real-time intelligence signals that can influence geopolitical narratives, public opinion and diplomatic decisions, according to market observers.

Polymarket data is widely shared on platforms including X, formerly known as Twitter, and Telegram. A coordinated bet can generate news coverage and affect traditional financial markets before official confirmations exist, analysts said.

The controversy has reached Washington. Congressman Ritchie Torres introduced the Public Integrity in Financial Prediction Markets Act of 2026, legislation designed to prohibit U.S. government officials from trading in markets related to government actions when they possess non-public information.

The bill has dozens of cosponsors in the House but has not been voted on and lacks a Senate counterpart, according to congressional records. No conclusive evidence has emerged linking trades on Iran to U.S. government insiders, though the pattern of sudden bets and reversals has raised concerns about prediction markets operating in regulatory gray areas.

The controversy highlights concerns about how betting activity on prediction platforms may influence public perception of future events, potentially transforming decentralized finance platforms into tools that shape geopolitical narratives, according to regulatory experts and market analysts.
