Anthropic has received investment proposals at a valuation of $800 billion.

      In summary: Anthropic has attracted investor offers valuing the company at around $800 billion, significantly up from its $380 billion valuation following a $30 billion funding round just two months prior. This remarkable increase comes after an exceptional revenue growth trajectory, which saw Anthropic's annualized revenue soar from $1 billion at the close of 2024 to $30 billion by early April 2026, coinciding with the introduction of its Claude Mythos model via Project Glasswing.

      According to Bloomberg, the offers place Anthropic's valuation at roughly $800 billion, more than doubling the $380 billion valuation reached during a $30 billion funding round only two months ago. The company has, however, opted not to accept these offers yet.

      Such a valuation is extraordinary, even for a sector that has transformed traditional growth metrics. If Anthropic were to secure an $800 billion raise, it would position itself among the most valuable private companies ever and put it in direct valuation competition with OpenAI. This would also mean that a company founded in 2021 achieved a valuation that took Salesforce two decades and Microsoft three to attain.

      The revenue supporting this valuation is impressive. Anthropic ended 2024 with around $1 billion in annualized revenue, which escalated to $9 billion by the end of 2025, $14 billion by February 2026, and between $19 and $20 billion by March. By early April, Anthropic surpassed $30 billion in annualized revenue, marking about 1,400% year-over-year growth.

      Axios put it succinctly: no company in American history has experienced such rapid growth. The Claude Code alone reached $2.5 billion in annualized revenue in February, more than doubling since the year's start. This growth is primarily driven by enterprise adoption, with Anthropic's Claude models now integrated into workflows across sectors such as finance, legal, healthcare, and software development.

      With $30 billion in annualized revenue and continuing to grow, an $800 billion valuation equates to roughly a 27x revenue multiple. Although this is high by traditional standards, it may not be entirely irrational for a company whose revenue is doubling every few months. The key question remains how sustainable this growth trajectory will be.

      Anthropic's valuation history resembles a steep curve. In March 2025, the company raised $3.5 billion, achieving a valuation of $61.5 billion. By its Series F in September 2025, the implied valuation had escalated to $183 billion. In February 2026, it closed a $30 billion round, the second-largest venture funding deal ever, at $380 billion. Now, merely weeks later, investors are proposing nearly $800 billion.

      Current investors are realizing substantial gains. Google holds a 14% stake in Anthropic, acquired through several investments totaling around $3 billion, which has led to reported net gains of $10.7 billion on these equity securities. Amazon, which has invested about $8 billion and serves as Anthropic's primary cloud and training partner, has reported a $9.5 billion pretax gain connected to Anthropic's rising valuation in its Q3 results. Both firms now possess stakes worth multiples of their initial investments.

      The company is also engaging in preliminary discussions with Goldman Sachs, JPMorgan, and Morgan Stanley regarding a potential IPO, expected as early as October 2026, with a projected raise of over $60 billion. An $800 billion pre-IPO valuation would herald one of the largest tech public offerings in history.

      Two factors have altered Anthropic’s situation since February. The first is the revenue surge itself, which has surpassed even optimistic forecasts. The second is Claude Mythos, the model unveiled on April 7 through the Project Glasswing initiative.

      Mythos Preview autonomously identified thousands of zero-day vulnerabilities in major operating systems and web browsers, including a 27-year-old bug in OpenBSD and a 17-year-old remote code execution flaw in FreeBSD. It achieved success in 73% of expert-level capture-the-flag cybersecurity tasks and was the first model to complete a 32-step simulated corporate network attack end-to-end. Anthropic made this model available exclusively to 11 organizations, including Apple, Google, Microsoft, and AWS, under a defensive initiative valued at $100 million.

      The decision to withhold Mythos from public release itself signified a strong message, illustrating that Anthropic possesses capabilities it deems too powerful for widespread access—a claim that, whether warranted or not, serves as a credibility indicator for investors assessing the company’s technical position in relation to OpenAI and Google DeepMind.

      An $800 billion valuation positions Anthropic in a realm where conventional venture capital frameworks no longer apply. Investors are no longer viewing it as a startup but rather as a potential platform company poised to become as fundamental to the economy as cloud computing or mobile operating systems.

      The bullish argument is clear: Anthropic's revenue is growing
