Anthropic, the San Francisco AI company behind the Claude assistant, is fielding preemptive offers to raise between $40 billion and $50 billion at a valuation of $850 billion to $900 billion, according to sources cited by TechCrunch. The company’s board is expected to decide on final terms in May 2026. If completed at the top of that range, the deal would make Anthropic the most valuable private company in history and rank among the largest private capital raises ever executed. Anthropic declined to comment.
A Valuation That Has More Than Doubled in Three Months
The scale of the repricing is striking even by 2026 AI standards. In February 2026, Anthropic closed its most recent funding round at a $380 billion valuation. The new target — approximately $875 billion at the midpoint — represents a more than 130% jump in roughly 90 days, a compression of the typical private-market rerating cycle that would normally take years.
Driving the rerating is explosive revenue growth. Anthropic’s annualized revenue run rate crossed $30 billion this month — up from approximately $9 billion at the end of 2025 — according to the same reporting. Some sources estimate the current run rate is closer to $40 billion. The primary engines are Claude Code, the company’s AI-assisted software development platform, and Cowork, an AI collaboration product. Looking ahead, sources cite finance, life sciences, and healthcare as the next major expansion verticals — sectors where investors believe Anthropic has barely begun to penetrate.
Strategic Capital Already in Place: Google and Amazon
Before this new round, Anthropic had already locked in two of the largest strategic-investment commitments in private-market history, both structured as hybrid equity-and-cloud deals.
In April 2026, Google announced plans to invest up to $40 billion in cash and compute. The commitment is structured in two tranches: $10 billion committed immediately at a $350 billion valuation, with an additional $30 billion contingent on performance milestones. Anthropic already relies heavily on Google Cloud’s tensor processing units (TPUs) for AI training, and the two companies have a separate compute partnership with chipmaker Broadcom that will provide multiple gigawatts of TPU-based capacity beginning in 2027.
Also in April, Amazon committed an additional $5 billion in Anthropic, bringing its total investment to $13 billion. In exchange, Anthropic pledged to spend more than $100 billion on Amazon Web Services over the next decade, including securing up to 5 gigawatts of compute capacity — primarily on Amazon’s Trainium AI accelerator chips (Trainium2 through the as-yet-unreleased Trainium4), positioning Amazon as a credible alternative to Nvidia in the AI infrastructure stack.
Together, those two strategic relationships represent capital and cloud-infrastructure commitments approaching $155 billion — a figure that dwarfs conventional venture backing and is reshaping the template for how the largest AI companies are financed.
The Open Round: Demand Far Exceeds Allocation
The $40–50 billion round being structured now would come from third-party investors outside the Google and Amazon strategic agreements. By all accounts, demand is overwhelming supply. Multiple preemptive term sheets have already arrived. In a striking illustration of the imbalance, a single institutional investor that is prepared to commit $5 billion has reportedly been unable to secure a meeting with Anthropic CFO Krishna Rao — suggesting available allocation is scarce at any price.
As recently as mid-April, Anthropic was turning away term sheets that valued the company above $800 billion. The board’s apparent decision to proceed now signals the company has concluded both the valuation and the investor set meet its criteria for a final pre-IPO raise.
Comparing the Two Trillion-Dollar AI Rivals
| Company | Round / Event | Date | Round Size | Post-Money Valuation | Notable Investors |
|---|---|---|---|---|---|
| Anthropic | Funding round | Feb 2026 | — | $380B | Google, Amazon |
| OpenAI | Capital raise | Feb 2026 | $110B+ | ~$852B | SoftBank, Amazon ($50B) |
| Anthropic | Planned round | May 2026 (expected) | $40–50B | $850–900B | Multiple preemptive offers |
Anthropic’s Valuation Trajectory
Final Round Before the IPO?
Sources familiar with the process describe the planned raise as Anthropic’s last private funding round before a potential initial public offering. With revenue run rates in the $30–40 billion range and investor demand overwhelming available supply, the company would have strong IPO optionality within the next 12 to 24 months, particularly if it continues to scale into high-value enterprise verticals.
What makes this raise structurally distinct from a conventional late-stage venture round is the composition of capital already in place. Google’s up-to-$40 billion commitment and Amazon’s $13 billion stake — both tied to cloud-compute agreements — mean that third-party investors in this round are effectively competing for allocation with two of the world’s largest technology companies. That dynamic has given Anthropic unusual pricing power: the company can decline term sheets at $800 billion valuations and still have a queue of institutional capital waiting at the door.
What It Signals for Private Capital Markets
Anthropic’s fundraising arc illustrates a structural shift in how the largest private technology companies access capital. The traditional VC model — small checks, board seats, governance protections — has been displaced at the top tier by a new form of strategic corporate financing, where hyperscale cloud providers make equity investments in exchange for long-term compute spending commitments. The result is a blended instrument that is simultaneously a venture investment, a revenue guarantee, and an infrastructure procurement contract.
For institutional investors seeking exposure to frontier AI — sovereign wealth funds, university endowments, pension funds — the allocation window is extraordinarily narrow. One source told TechCrunch that a single buyer ready to commit $5 billion cannot get a meeting with the CFO. That is not a capital supply problem. It is an allocation problem — and it reflects how concentrated private-market returns have become in the current AI cycle.
