Bloomberg's Katie Roof posted the story at 4:18 PM Eastern on Wednesday, twenty minutes before Meta's earnings would dominate every screen on Wall Street. Anthropic, the maker of Claude, was reviewing preemptive funding offers that would value the company at more than $900 billion. The proposed raise was about $50 billion in fresh primary capital. The implied price tag would push Anthropic past OpenAI as the most valuable private artificial intelligence company in the world.
The number was not the surprising part. The arithmetic was.
Seventy-six days earlier, on February 12, 2026, Anthropic had closed its Series G at a $380 billion post-money valuation, raising $30 billion in what was then the second-largest private tech financing in history. If the new offers convert at the high end of the range, Anthropic's primary valuation will have 2.4x'd in eleven weeks. That is not how late-stage venture math is supposed to work, even in a market this hot.
CNBC, TechCrunch, and PYMNTS confirmed the Bloomberg reporting within hours. None of the sources said the round had been agreed. All of them said the same thing about timing: the company will make a definitive decision at a board meeting in May. The IPO that bankers had been preparing for an October listing is still on the table, but the size of the new private offers is forcing the question of whether to raise once more before going public.
What Investors Are Looking At
The metric that snapped attention earlier this month was Anthropic's $30 billion annualized revenue, disclosed by the company on April 7, 2026. That number was up from $9 billion at year-end 2025 and $14 billion when the Series G priced. In percentage terms, the run rate grew 58 percent in fifty-four days.
Bloomberg also reported Anthropic told investors during the previous round that it expected to reach $34.5 billion in annualized revenue by the end of 2026. The company is now ahead of that schedule by about eight months. Claude Code, the agentic coding product that competes with Cursor and OpenAI's Codex, accounts for an outsized share of the uplift.
| Anthropic Revenue Run Rate | Reported At | Source |
|---|---|---|
| $9 billion | End of 2025 | Bloomberg, January 2026 |
| $14 billion | February 12, 2026 (Series G close) | Anthropic press release |
| $30 billion | April 7, 2026 | Anthropic confirmation; Bloomberg, The Register |
| $34.5 billion (target) | End of 2026 | Bloomberg (investor projection) |
For comparison, OpenAI closed its most recent primary round in February at a post-money of about $852 billion. Anthropic's offered range tops that figure even at the low end. The implied conclusion: at least one major institutional investor now believes Anthropic is the more valuable company on a fully-diluted basis, despite a smaller user-facing consumer footprint and a younger product line.
The Compute Side of the Bet
Investor enthusiasm is not just about revenue. Anthropic is now sitting on the largest committed compute pipeline of any model lab outside Microsoft. In April alone the company stacked three deals into the public record. Amazon committed an additional $25 billion investment paid back in AWS Trainium consumption. Google agreed to invest up to $40 billion contingent on TPU consumption. Broadcom signed on to ship custom Google TPU silicon directly to Anthropic.
In total, Anthropic's compute commitments now span roughly 3.5 gigawatts of contracted power. The capex side of the AI buildout has effectively underwritten the company's growth two years out. What it has not done is settled the question of how much of that growth shows up as profit, or how to price it.
That question is precisely what the board will face in May. A new private round at $900 billion makes the October IPO more about creating liquidity for employees and early backers than about raising operating capital. A skipped round and a direct path to public markets would expose the same valuation to a different audience — institutional buyers who do not give the same price to the same metrics.
The Other Side: The Accounting Dispute
Not everyone takes the $30 billion run rate at face value. After the April 7 announcement, OpenAI publicly contested Anthropic's accounting, arguing the gross-revenue figure is overstated by roughly $8 billion because it includes amounts billed through Amazon Web Services and Google Cloud rather than only Anthropic's net take.
Anthropic's response was that it is the principal in those transactions: it sets the price, builds the model, and uses the cloud providers as distribution channels. Under that framing, gross revenue recognition is the correct treatment. SEC filings tied to the eventual IPO will require the company to defend that position in detail.
A second skeptical thread comes from the secondary market. Forge Global, the platform where pre-IPO shares trade between accredited investors, briefly hit an implied $1 trillion valuation for Anthropic shares last week. Secondary trades typically over- or undershoot primary rounds; in this case the secondary was running ahead of even the top offer Bloomberg described. Several public-market analysts told Bloomberg the gap suggests private demand is being driven by a small number of large allocators, not broad-based price discovery.
Anthropic itself has not commented publicly on the offers, the proposed valuation, or the IPO timing.
The Wider Funding Signal
For practitioners building on Claude, the deal carries a few specific reads. A $50 billion injection into Anthropic primarily underwrites more compute, more partner deals, and more head count, particularly on inference reliability, on enterprise sales, and on the agentic side of the product line that competes with Microsoft's Copilot and Google's Vertex AI. It does not, in the near term, change the price of Claude tokens.
For practitioners watching OpenAI, the implication is sharper. If Anthropic prices a primary round above $900 billion, OpenAI's own pre-IPO marketing has to account for a faster-growing competitor that has now outpaced it on at least one disputed revenue metric. The Microsoft-OpenAI relationship was restructured a week ago precisely to allow OpenAI to negotiate cloud capacity outside Azure. That restructuring assumed a particular pace of growth on the OpenAI side. A higher Anthropic valuation pressures the assumption.
For everyone else (Mistral, Cohere, the open-weight labs), the signal is colder. The two-company concentration of frontier-lab funding is widening, not narrowing. A successful $50 billion private round followed by a $60-billion-plus IPO would put more capital behind Anthropic alone than the entire venture-capital industry deployed into AI startups in 2023.
The Bottom Line
Anthropic's Series G priced the company at $380 billion. That round sold less than three months ago. By the end of next week, the company will have a board paper in front of it asking whether to take a second round at $900 billion before going public, or to skip it and price the same shares at the IPO instead.
Both options exist because $30 billion in annualized revenue, a number the company put on the wire on April 7, is what the market now prices. Both options carry execution risk. The private path requires absorbing dilution at a moment when private-market AI valuations are visibly running ahead of secondary-market clearing prices. The public path requires defending those numbers under SEC disclosure scrutiny, including the contested gross-revenue accounting question OpenAI raised this month.
Either way, the company that did not exist in 2020 and was valued at $61 billion in March 2025 will, by autumn, be sized as one of the ten most valuable companies in the United States. As one investor put it to Bloomberg: the only debate left is whether the price is Anthropic's last private number or its first public one.
