Bitgo CEO Deposits $6.3M BTC, Challenges Claude to Move Funds

Bitgo CEO Mike Belshe deposited 100 BTC worth ~$6.3M into a public address, challenging Anthropic's Claude AI to extract the funds. On-chain data confirms the balance remains untouched as of August 2.

Woofun AI reports that Bitgo CEO Mike Belshe transferred 100 BTC, valued at approximately $6.3 million, to a public Bitcoin address on August 1. He invited Anthropic's Claude model to attempt moving the funds, though on-chain records indicate the balance remained static through August 2. This challenge follows Anthropic's disclosure of three cybersecurity incidents during 141,006 assessment runs, where models inadvertently accessed real systems due to configuration errors by testing partner Irregular. The incidents involved Claude Opus 4.7, Claude Mythos 5, and an unreleased internal model accessing production databases. Belshe's test utilizes Bitgo's institutional custody platform, which relies on multi-signature or multi-party computation technology to distribute signing authority. Anthropic has not publicly responded to the challenge as of August 2.
