Anthropic Nears $800B Valuation as Mythos Draws Federal Tests

Venture firms and secondary-market bidders have pushed Anthropic toward valuation talk as high as $800 billion. The company closed a February funding round at a $380 billion valuation. On secondary trading platforms, some prices reach roughly $688 billion, up about 75% in three months, linked to growth around its Claude Code product and other enterprise offerings.

Anthropic reported its annualized revenue run rate rose to $30 billion from $9 billion at the end of last year. The company reported more than 1,000 enterprise customers now spend over $1 million a year, a count that doubled in under two months.

Last week Anthropic released Claude Mythos, a model designed to scan software for vulnerabilities. Anthropic reported Mythos uncovered serious flaws that human researchers had not found. Staff from at least two large federal agencies have contacted Anthropic about potential cyber defense uses, and personnel from multiple congressional committees have requested briefings to assess the model’s scanning abilities.

The Commerce Department’s Center for AI Standards and Innovation is testing Mythos and has evaluated its risks and capabilities. Contacts with the center and other agencies continued after federal guidance in late February directed agencies to stop using Anthropic technology. That guidance followed the company’s public opposition to Pentagon use of its models for autonomous lethal attacks or mass surveillance. Defense officials later labeled Anthropic a supply chain risk, a designation that effectively bars its models from use on Defense Department contracts.

Some private firms are also running evaluations of Mythos. JPMorgan Chase is testing a preview of the model as part of its effort to adopt AI without increasing exposure to attackers. On the bank’s earnings call, JPMorgan CEO Jamie Dimon warned, “AI’s made it worse, it’s made it harder,” and later added that Mythos’ finding of thousands of vulnerabilities indicates more fixes are needed. Dimon noted the bank invests heavily in cybersecurity and coordinates with government agencies.

Anthropic developed the Claude family of models and expanded into developer and enterprise tools such as Claude Code before launching Mythos. The company’s revenue growth and large enterprise customer base have attracted investor interest and pushed secondary-market pricing higher even as Defense Department restrictions limit federal defense uses.
