In summary: Anthropic has attracted investor proposals valuing the company at around $800 billion, more than doubling its $380 billion valuation from a $30 billion funding round just two months prior. This increase is driven by a remarkable revenue growth, with Anthropic jumping from $1 billion in annualized revenue at the end of 2024 to $30 billion by early April 2026, along with the launch of its Claude Mythos model via Project Glasswing.
Per Bloomberg, Anthropic has received investor offers valuing it at about $800 billion, more than doubling the $380 billion valuation achieved with a $30 billion funding round two months ago. Anthropic has so far declined these offers.
The figure is notable even within a sector known for rapid growth. An $800 billion valuation would place Anthropic among the most valuable private companies ever, directly competing with OpenAI. This would mean a company founded in 2021 had achieved a valuation that took Salesforce two decades and Microsoft three.
The revenue basis
The $800 billion valuation is underpinned by Anthropic’s extraordinary revenue growth. By the end of 2024, annualized revenue was about $1 billion, reaching $9 billion at 2025’s end, $14 billion by February 2026, and $19 to $20 billion by March. In early April, Anthropic surpassed $30 billion in annualized revenue, marking roughly 1,400% year-over-year growth.
Axios bluntly stated: no American company has ever grown like this. Claude Code alone achieved $2.5 billion in annualized revenue in February, doubling since the year’s start. Growth is driven by enterprise adoption, with Anthropic’s Claude models integrated across finance, legal, healthcare, and software development.
At $30 billion in revenue and rising, an $800 billion valuation implies a 27x revenue multiple. While high by conventional standards, it may not be irrational for a company doubling revenue so rapidly. How long this growth continues remains the question.
The funding climb
Anthropic’s valuation history shows exponential growth. In March 2025, it raised $3.5 billion at a $61.5 billion valuation. By September 2025’s Series F, the valuation reached $183 billion. In February 2026, a $30 billion round valued it at $380 billion. Now, investors are offering nearly $800 billion.
Existing investors have seen significant returns. Google’s 14% stake, acquired for about $3 billion, has yielded $10.7 billion in gains. Amazon, investing roughly $8 billion as the primary cloud partner, reported a $9.5 billion pretax gain in Q3. Both companies now hold stakes worth multiples of their original investments.
Anthropic is in talks with Goldman Sachs, JPMorgan, and Morgan Stanley for a potential IPO as early as October 2026, potentially raising over $60 billion. An $800 billion pre-IPO valuation would set a record for tech public offerings.
Recent developments
Two factors have shifted Anthropic’s position since February. Firstly, revenue growth has surpassed optimistic forecasts. Secondly, on April 7, Anthropic unveiled the Claude Mythos model through Project Glasswing.
Mythos Preview autonomously found thousands of zero-day vulnerabilities in major operating systems and browsers, including a 27-year-old OpenBSD flaw. It passed 73% of expert-level cybersecurity challenges and was first to solve a 32-step simulated corporate network attack. The model is exclusive to 11 organizations like Apple and Google under a $100 million initiative.
The choice not to release Mythos publicly signals Anthropic’s capabilities are deemed too potent for general access, serving as a credibility marker for investors comparing it to OpenAI and Google DeepMind.
Valuation considerations
An $800 billion valuation places Anthropic where typical venture capital frameworks fail. At this scale, investors are pricing a potential platform company, comparable to core technologies like cloud computing.
The bull case: Anthropic’s record growth, competitive models, and high demand for AI capabilities suggest a vast revenue potential. If Claude becomes essential for global knowledge work, revenue could reach hundreds of billions.
The bear case: A 27x revenue multiple depends on sustained hypergrowth, rarely maintained long-term. Intense competition exists in AI
