Suspected Insider Wallets Net $1.2M Betting on ZachXBT’s Axiom Expose

A small group of crypto wallets earned over $1.2 million by betting on a Polymarket contract linked to an onchain investigation into DeFi platform Axiom, raising concerns about advance knowledge in prediction markets. Data from Dune shows the eight most profitable wallets collectively made about $1.2 million, with onchain researcher Defioasis suggesting eight of the top ten wallets exhibit insider trading patterns. This follows ZachXBT's Thursday exposé alleging insider trading by Axiom employee Broox Bauer and others since early 2025; Axiom responded by expressing shock and revoking access to the tools used. This incident echoes previous insider trading concerns on prediction markets, such as a highly profitable bet on the removal of Venezuelan President Nicholas Maduro just hours before a US-backed military operation. Polymarket, the largest decentralized prediction market, is simultaneously facing increased regulatory scrutiny globally, with countries like Hungary, Portugal, and Ukraine blocking access due to unlicensed gambling concerns.
