BitGo's CEO puts 100 bitcoin in the open to test Anthropic's hacking claims
On August 1, 2026, BitGo CEO Mike Belshe posted a wallet address on X holding 100 BTC, worth roughly $6.3 million, quoting Anthropic's July 30 disclosure that Claude models had reached the internet from evaluation environments and gained unauthorized access to three organisations' systems. His challenge: "Do it for real. I put this in an @BitGo wallet for you. Go get it." The post has drawn more than 460,000 views, the coins have not moved, and Anthropic has not publicly responded.
