Polymarket recently created a contract that attracted significant attention, pulling in roughly $40 million in betting volume since Monday. This contract allowed users to speculate on which company would be implicated in an insider trading investigation. At least 12 wallets were noted to have profited collectively over $1 million before the official revelation was made. In particular, Polysights, an on-chain data analysis service, identified five wallets that collectively wagered around $50,000, resulting in a profit of $266,000.
During the week, the betting odds saw significant fluctuations. At one point, the odds for the company Axiom reached a peak of 46.2%, while Meteora, another contender, led the market for most of the week with odds exceeding 50%. Such market dynamics have raised questions about potential insider trading, as these fluctuations occurred ahead of official announcements.

The behavior of bettors on Polymarket’s platform has raised significant concern over potential insider trading activities. The largest recorded stakeholder, known as predictorxyz, held 477,415 shares at an average purchase price of $0.14, earning a profit of $411,000. Following closely, the second-largest stakeholder acquired 109,450 shares at $0.33 each. During the week, the market dynamics saw a swing in betting odds, particularly for Axiom, which reached a peak of 46.2% odds on late Wednesday. Although Meteora was the frontrunner, maintaining odds over 50% for most of the week, these odds fell following further developments.
Investigative blockchain sleuth, ZachXBT, played a pivotal role in examining these activities. He engaged in several interviews and reached out to Axiom for comments, despite the platform making it challenging to attribute specific transactions due to its offshore nature, which lacks identity verification protocols. Axiom expressed being ‘shocked and disappointed’ by these revelations, announcing their intent to investigate the situation, though they refrained from commenting on potential employee involvement in the wagers.

Polymarket’s market design has come under scrutiny for apparently benefiting individuals involved in insider trading rather than aiding investigators. The absence of identity verification on Polymarket’s offshore platform complicates the attribution of trades to specific parties, as the platform does not require identity checks. This lack of transparency makes cooperation essential for determining the sources of significant betting actions.
A notably critical perspective focuses on the question of whether insiders can exploit their investigation to place bets on themselves. Indeed, at least 12 wallets reportedly gained more than $1 million before the findings were made public, heightening concerns over the ethical stance of such market activities. The investigation has so far revealed vulnerabilities in the market structure. These vulnerabilities allowed a small number of individuals to gain substantial profits, showcasing a fundamental flaw in the platform’s operational integrity.
In summary, the investigation of Polymarket’s contract exposed issues related to insider trading, highlighting a gap in regulatory oversight and market design that complicates the enforcement of fair trading practices.
