The New York Stock Exchange and its parent company, Intercontinental Exchange, are now using Anthropic’s Claude Mythos Preview to scan their infrastructure for security flaws. The deployment, announced June 3, makes ICE one of the largest financial institutions to join Anthropic’s Project Glasswing, a cybersecurity initiative that pairs advanced AI with critical infrastructure operators to find and fix software vulnerabilities before attackers do.
What Project Glasswing actually does
Anthropic’s Claude Mythos Preview model is deployed across ICE’s platforms, including its exchanges and clearing houses, to identify vulnerabilities that might otherwise sit undetected for years. During its testing phases, Mythos Preview has already identified thousands of critical-severity vulnerabilities across various codebases. Some of those flaws had been lurking for over two decades, including a 27-year-old vulnerability in OpenBSD and a 16-year-old bug in FFmpeg.
Project Glasswing launched in early April 2026 with an initial cohort of roughly 50 organizational partners. In under two months, that number has ballooned to approximately 200 critical-infrastructure entities. Anthropic is backing the initiative with up to $100 million in usage credits for participating organizations, plus $4 million in donations earmarked for open-source security groups.
