In short: Anthropic has received investor offers valuing the company at approximately $800 billion, more than doubling its $380 billion valuation from a $30 billion funding round closed just two months ago. The surge follows an unprecedented revenue trajectory that has taken Anthropic from $1 billion in annualised revenue at the end of 2024 to $30 billion by early April 2026, alongside the release of its Claude Mythos model through Project Glasswing.
Anthropic has received investor offers valuing the company at approximately $800 billion, according to Bloomberg, a figure that would more than double the $380 billion valuation at which it closed a $30 billion funding round just two months ago. The company has so far resisted accepting the offers.
The number is remarkable even by the standards of a sector that has redefined what growth looks like. If Anthropic were to raise at $800 billion, it would rank among the most valuable private companies in history and place the Claude developer in direct valuation competition with OpenAI. It would also mean that a company founded in 2021 had reached a valuation that took Salesforce two decades and Microsoft three to achieve.
The revenue behind the number
What makes the $800 billion figure less absurd than it sounds is Anthropic’s revenue trajectory. The company ended 2024 at roughly $1 billion in annualised revenue. By the end of 2025, that had reached $9 billion. By February 2026, it was $14 billion. By March, $19 to $20 billion. In early April, Anthropic crossed $30 billion in annualised revenue, a figure that represents approximately 1,400% year-over-year growth.

Axios described it bluntly: no company in American history has ever grown like this. Claude Code alone hit $2.5 billion in annualised revenue in February, more than doubling since the start of the year. The growth is being driven by enterprise adoption, with Anthropic’s Claude models now embedded in workflows across finance, legal, healthcare, and software development.
At $30 billion in annualised revenue and growing, an $800 billion valuation implies a roughly 27x revenue multiple. That is high by any conventional measure, but it is not obviously irrational for a company whose revenue is doubling every few months. The question is how long that trajectory can hold.
The funding escalator
Anthropic’s valuation history reads like a parabolic curve. In March 2025, the company raised $3.5 billion at a $61.5 billion valuation. By its Series F in September 2025, the implied valuation had reached $183 billion. In February 2026, it closed a $30 billion round, the second-largest venture funding deal ever, at $380 billion. Now, just weeks later, investors are offering nearly $800 billion.
The existing investors are sitting on extraordinary gains. Google owns 14% of Anthropic, a stake acquired through multiple investments totalling roughly $3 billion, and has reported $10.7 billion in net gains on those equity securities. Amazon, which has invested an estimated $8 billion and secured a position as Anthropic’s primary cloud and training partner, reported a $9.5 billion pretax gain tied to Anthropic’s rising valuation in its Q3 results. Both companies hold stakes that are now worth multiples of their original investments.
The company is also in early talks with Goldman Sachs, JPMorgan, and Morgan Stanley about a potential IPO that could come as early as October 2026, with an expected raise exceeding $60 billion. An $800 billion pre-IPO valuation would set the stage for what would be one of the largest public offerings in technology history.
What changed
Two things have shifted Anthropic’s position since February. The first is the revenue acceleration itself, which has exceeded even bullish projections. The second is Claude Mythos, the model Anthropic unveiled on 7 April through its Project Glasswing initiative.
Mythos Preview autonomously discovered thousands of zero-day vulnerabilities across every major operating system and web browser, including a 27-year-old OpenBSD bug and a 17-year-old FreeBSD remote code execution flaw. It succeeded on 73% of expert-level capture-the-flag cybersecurity tasks and was the first model to solve a 32-step simulated corporate network attack end-to-end. Anthropic made the model available only to 11 organisations, including Apple, Google, Microsoft, and AWS, under a $100 million defensive initiative.
The decision not to release Mythos publicly was itself a statement. It signalled that Anthropic possesses capabilities it considers too powerful for broad access, a claim that, whether justified or not, functions as a credibility marker for investors evaluating the company’s technical position relative to OpenAI and Google DeepMind.
The valuation question
An $800 billion valuation places Anthropic in territory where the usual venture capital frameworks break down. At this scale, investors are not pricing a startup; they are pricing a potential platform company, one that could become as foundational to the economy as cloud computing or mobile operating systems.
The bull case is straightforward: Anthropic’s revenue is growing faster than any company in history, its models are competitive with or ahead of OpenAI’s on multiple benchmarks, and enterprise demand for AI capabilities shows no sign of slowing. If Claude becomes the default AI layer for a significant portion of global knowledge work, the revenue ceiling is measured in hundreds of billions, not tens.
The bear case is equally clear. Revenue multiples of 27x assume sustained hypergrowth, and no company has maintained growth rates of this magnitude for more than a few quarters. The AI market is intensely competitive, with OpenAI, Google, Meta, and a growing roster of open-source alternatives all fighting for the same enterprise budgets. Anthropic’s costs are enormous: training frontier models, building infrastructure at scale, and competing for talent against companies with deeper pockets. The path from $30 billion in revenue to profitability at a level that justifies $800 billion in enterprise value is not guaranteed.
There is also the broader question of whether AI valuations have detached from fundamentals in ways that will eventually correct. The sector has absorbed hundreds of billions in investment on the premise that AI will restructure the global economy. If adoption curves flatten, or if commoditisation drives margins down faster than revenue grows, the companies that raised at peak valuations will face the most painful adjustments.
For now, though, the money keeps flowing. Anthropic has not accepted the $800 billion offers, which suggests either that it believes the price will go higher, or that it is holding out for terms that give it more control over its cap table ahead of a potential IPO. Either way, the fact that multiple investors are willing to write cheques at this valuation tells you everything about where the market thinks AI is heading, and how much it is willing to bet on that conviction.
