Anthropic is expanding Project Glasswing to approximately 150 organizations across more than 15 countries, granting access to Claude Mythos for vulnerability detection in power, water, healthcare, communications, and hardware sectors. The expansion follows an early-April pilot with 50 partners including the U.S. government and coincides with Anthropic's confidential IPO filing and a $65 billion funding round at nearly $1 trillion valuation. Claims that the model identified thousands of zero-day vulnerabilities affecting over 100 million people remain supported only by company statements reported in TechCrunch.
