Key Takeaways:
- Three newly created Polymarket wallets earned $630,484 by betting on Venezuela’s president leaving office just hours before his arrest
- The wallets were pre-funded days in advance and placed large bets only on Maduro- and Venezuela-related markets
- Blockchain data suggests a clear case of insider trading, raising new concerns around prediction market integrity
Just hours before Venezuelan President Nicolás Maduro was arrested, a small cluster of Polymarket wallets placed unusually confident bets on his removal from office. The timing, scale, and behavior of those wallets have triggered widespread scrutiny across the crypto and prediction market community.
Insider Wallet Activity Raises Red Flags on Polymarket
According to on-chain analyst Lookonchain, three wallets executed highly profitable positions on Polymarket markets predicting that Maduro would be out of office. The combined profit totaled $630,484, realized within hours of the real-world political event.
What makes the case striking is not only the profit, but the preparation. All three wallets were created and funded days before the bets were placed. Then, shortly before Maduro’s arrest became public, each wallet entered large positions with no apparent hedging or diversification.
The wallets showed no history of participating in unrelated prediction markets. Their entire activity was concentrated on Venezuela and Maduro-related outcomes, suggesting foreknowledge rather than speculative behavior.

Breaking Down the Three Wallets
The gains were never fairly spread, but every wallet made disproportionately high returns to its original capital.
- Wallet 0x31a5 invested roughly $34,000 and exited with $409,900 in profit
- Wallet 0xa72D committed $5,800, turning it into approximately $75,000
- Wallet SBet365 placed $25,000 and earned around $145,600
Collectively, these trades were one of the brightest applications of asymmetric information that has ever been witnessed in a decentralized prediction market.
Patterns That Point to Insider Information
The wallets did not creep in and check liquidity of the market. On the contrary, they bet with a lot of certainty just before the event which is normally the sign of a high confidence. On-chain transparency allowed reconstructing the sequence of actions step after step, but it showed that prediction markets are highly vulnerable to insiders that may gain access to confidential data.
How Prediction Markets Turn Information into Profit
Polymarket provides users with an opportunity to bet on the real-life results with crypto-based contracts. Prices embody aggregate probability conjectures, which adapt dynamically as the participants trade.
The insiders manipulate such probabilities when they choose to act upon non-public information, before the market any such action has a chance to respond. This is an illegal conduct in conventional finance. With decentralized prediction markets, there is no enforcement.
Since Polymarket is on-chain these trades could be seen virtually instantly after settlement. But being visible does not stop exploitation, particularly when there are neither identity requirements nor disclosure obligations.
Crypto’s Insider Trading Problem Is Getting Louder
This event underscores the fact that there is a wider problem in the crypto markets: information asymmetry. Although blockchains are transparent, access to real-world intelligence is disproportionately distributed.
This imbalance is enhanced by prediction markets. Political arrests, military operations, regulatory ruling and so on are usually done by an insider circle of people much before the whole society is made aware of the truth. When such insiders have the ability to install crypto wallets hustle free, profits may be hacked out with minimal immediate impact.
There have been similar concerns on:
- Election-related markets
- Geopolitical conflict predictions
- Regulatory approval or enforcement actions
Each case tests whether decentralized platforms can balance openness with fairness.

Regulatory and Platform Risk Going Forward
Such platforms as Polymarket are already regulated in a number of jurisdictions. Notorious cases such as this one may speed up the demand towards stricter regulations, such as:
- Limits on bet sizing for sensitive political events
- Delayed settlement mechanisms
- Enhanced monitoring of wallet behavior
There were no rules violated at the protocol level, but the optics are harmful. Markets are based on the belief that the prices are based on collective judgment and not insider knowledge.
To traders, it is a lesson that not every market is an equal. Sudden turn decisions can be viewed as information leakage as opposed to actual sentiment change. In the case of platforms, it increases the price of doing nothing as recurrent cases may jeopardize the ultimate credibility.
