According to the investigator, Bauer utilized internal tools to find hidden wallets of crypto influencers through referral codes and UIDs, then shared this information with a group of accomplices.

The perpetrators compiled addresses in a Google spreadsheet, tracking early purchases of meme coins by major players. This allowed them to open positions before influencers began publicly promoting the coins.

ZachXBT released screenshots from April and August 2025 containing personal information of traders.

The publication of the investigation was preceded by a surge in activity on the prediction platform Polymarket, where betting volume on who ZachXBT would expose exceeded $38 million.

Hours before the announcement, the odds of Axiom being the "subject" of the investigation sharply rose to 35%.
