The Polymarket contract, which was supposed to reveal whom ZachXBT would name in his investigation, saw about $40 million in trading volume within a few days. After Axiom’s name was revealed, on-chain analysts noticed a group of new wallets that had taken large positions in advance and collectively earned more than $1 million. Instead of the expected distributed consensus, a significant portion of positions ended up concentrated among a limited number of wallets.
How This Contract Emerged
ZachXBT spent several days building interest in material about possible insider trading. Against this backdrop, Polymarket launched a prediction market with a simple question: which company would be at the center of the investigation? Trading volume quickly grew and surpassed the $40 million mark by the time of publication.
When Axiom’s name was made public, some trades already looked less like bets and more like prearranged positions.
What On-Chain Analysts Saw
Lookonchain identified 12 wallets that actively bought the Axiom outcome even before the material was released. According to the service, their combined profit exceeded $1 million.
Polysights, which monitors suspicious activity on Polymarket, separately noted five addresses with a total bet of about $50,000 and a final result of $266,000.
The key point is not the fact of the profit itself. More important is that the purchases appeared to be of “high conviction” and were made through new wallets. This pattern typically appears where a participant is not just assessing probabilities but acting with knowledge of the outcome.
Why the Structure of Bets Looks Unusual
Public data shows that the position on Axiom was concentrated among a small group of players. One of the largest participants acquired 477,415 contracts at an average price of about $0.14 and ended up with a profit of around $411,000 by the time the market settled. That’s about 7x relative to the average entry price.
Another large wallet bought 109,450 contracts at $0.33. With such distribution, the market ceases to be the “wisdom of the crowd.” It starts to resemble a situation where a few addresses effectively form one side of the book.
Until Wednesday, another platform, Meteora, was considered the favorite. Its probability remained above 50%. Late on Wednesday, the odds shifted in favor of Axiom, reaching as high as 46.2%. Purchases during this interval look either like a perfect interpretation of signals or the effect of a leak.
Where the Insider Information Could Have Come From
ZachXBT publicly noted that before publication, he contacted Axiom representatives and conducted interviews. This means there were several points of access within the company to information about what would be published and when.
In this configuration, a “leak” becomes not an exotic event but a basic risk. Bets could have been placed directly by employees or by any affiliated persons. Establishing a connection is difficult because Polymarket does not require mandatory user identification.
Axiom stated that it was “shocked and disappointed” by the investigation’s findings and will continue its internal review. The question of whether the company knew about employees betting on this market remained unanswered.
Prediction Markets Face an Old Problem
This case highlighted the vulnerability of any prediction markets. They aggregate information well when it is distributed among participants. But they instantly monetize asymmetry if data is held by a narrow group.
From a technical standpoint, the mechanism worked. The price shifted to where the “correct” outcome was. At the same time, the economic effect could be the opposite of the intent. Those being investigated may have been the ones to profit.
What Happens Next?
If suspicions are confirmed, pressure on Polymarket could increase. The higher the trading volume and the more visible the cases of leaks, the greater the likelihood that prediction markets will be forced to move toward stricter requirements and access controls.
If no evidence emerges, the story will still remain a marker. The public market gave a signal before publication, making the topic of insider information central not only for Axiom but for the entire model of such contracts.
