Anthropic Attracts Investor Offers at $800 Billion Valuation Following Mythos Release

Anthropic has received investor offers valuing the company at $800 billion following its April 2026 release of Claude Mythos, an AI model that autonomously discovered thousands of zero-day vulnerabilities including bugs dating back 27 years. The valuation represents more than double the $380 billion valuation from Anthropic's $30 billion funding round just two months earlier, though the company has resisted accepting the offers. Anthropic's revenue has exploded from $1 billion annualized at end of 2024 to over $30 billion by April 2026, representing 1,400% year-over-year growth. Major investors Google and Amazon have realized gains exceeding $10 billion and $9 billion respectively on their stakes, while Anthropic pursues early IPO discussions with Goldman Sachs, JPMorgan, and Morgan Stanley for a potential October 2026 offering expected to raise over $60 billion.
