A Polymarket contract tied to ZachXBT’s teaser drew roughly $27.6 million in trading volume before he named Axiom in an insider trading probe. The scale of speculation highlights how allegations of internal data abuse can ripple across trading venues and prediction markets.
On Thursday, blockchain investigator ZachXBT published findings alleging that employees at Axiom misused internal customer support tools to access private wallet data. The crypto trading platform, founded in 2024 by “Mist” and “Cal” and backed by Y Combinator’s Winter 2025 batch, has generated more than $390 million in revenue to date, according to ZachXBT.
Did Internal Tools Enable Insider Trading?
ZachXBT alleged that a senior business development employee known as “Broox,” based in New York, used internal dashboards to track users by referral code, wallet address, or user ID. Recordings cited in the report describe efforts to review wallets gradually “so it does not look that suspicious,” and to compile lists of private wallets tied to prominent crypto traders.

Several individuals whose wallet data appeared in leaked screenshots confirmed the accuracy of the information attributed to them, according to the investigator. ZachXBT also alleged that Broox and associates discussed using privileged access to help another team member profit $200,000 through trades, though he said confirming specific insider transactions would require Axiom’s internal logs.
The episode unfolded alongside heavy positioning on Polymarket, where traders bet on which company would be exposed, and onchain analysts flagged unusual activity. Lookonchain reported that one trader wagered more than $50,000 on Axiom at lower odds and exited for a $39,000 profit within a day, raising fresh questions about information leakage.

This sparked speculation that he might have inside information.

Axiom said it was “surprised and disappointed” that an employee allegedly abused internal tools and confirmed it had removed access while continuing to investigate. With ZachXBT suggesting potential U.S. jurisdiction due to employee location, the next catalyst will be whether regulators examine internal controls at centralized crypto trading platforms more closely.
