According to prominent blockchain investigator ZachXBT, multiple employees at the non-custodial trading platform Axiom, which is backed by Y Combinator, have been accused of engaging in insider trading. ZachXBT alleged that Broox Bauer, a senior business development employee at Axiom, abused access to internal tools to look up sensitive user details and track private wallet activity to facilitate insider trading since early 2025. Axiom has responded by removing access to these internal tools and promising to investigate and hold the offending parties responsible.

Why it matters

The allegations of insider trading at Axiom, a high-profile crypto startup, raise concerns about the lack of oversight and potential for abuse in the rapidly growing decentralized finance (DeFi) space. As crypto platforms gain more mainstream adoption, incidents like this could undermine public trust and lead to increased regulatory scrutiny of the industry.

The details

ZachXBT claimed that Bauer and other Axiom employees were able to use internal customer support tools to look up sensitive user details, including wallet addresses, which they then allegedly used to engage in insider trading. The investigator provided evidence of Bauer sharing private wallet information with others and mapping out wallet addresses linked to influencers in order to profit from their trading activity. While ZachXBT said it was difficult to pinpoint specific examples of insider trading due to the high volume of meme coin trades, he provided a screenshot showing around $300,000 in funds allegedly tied to Bauer.

  • In early 2025, Axiom employees allegedly began abusing internal tools to engage in insider trading.
  • On February 26, 2026, blockchain investigator ZachXBT publicly accused multiple Axiom employees of insider trading.

“Traders like Marcell are prime targets for this type of abuse since address reuse is less common and private wallets are rarely public, which makes privileged info much more valuable.”

This incident could lead to increased regulatory scrutiny and undermine public trust in the crypto ecosystem if not properly addressed.
