Anthropic’s $900 Billion Tag Tops OpenAI on a Different Scoreboard

Anthropic is in talks to raise at least $30 billion at a pre-money valuation north of $900 billion, a price that would push the Claude maker above OpenAI’s $852 billion mark from March. Bloomberg first reported the figure on April 29, and the Financial Times has since named Dragoneer, Greenoaks, Sequoia Capital and Altimeter Capital as lead investors, each writing checks of $2 billion or more.

The number is the headline. The underlying question is what these investors are actually paying for, because the company they are buying at $900 billion looks very little like the company OpenAI sold to its own backers eight weeks earlier.

Two Numbers, Two Different Companies

OpenAI’s close on March 31 was a consumer story. OpenAI’s official funding announcement framed the round around scale: $122 billion in committed capital at a post-money valuation of $852 billion, paired with growth figures that lean heavily on ChatGPT’s reach. The company says enterprise is closing in, making up more than 40% of revenue and on track to reach parity with consumer by the end of 2026, but the brand and the cash flow still come mostly from a chatbot used by hundreds of millions of people every week.

Anthropic’s valuation is built on the opposite arithmetic. Claude holds approximately 3.5% of the global generative AI chatbot market compared to ChatGPT’s roughly 60%, but in enterprise AI Claude holds an estimated 29% market share, and by mid-2025 Anthropic’s enterprise revenue had surpassed OpenAI’s. The two companies are competing in the same industry and trading at the same order of magnitude, but they are not selling the same thing.

The cleanest way to read the gap is by where the revenue concentrates:

• $30 billion annualized run rate at Anthropic, per the company’s February disclosure, with one source telling TechCrunch the real figure is closer to $40 billion.
• ~$24 billion implied annualized rate for OpenAI at $2 billion a month.
• $2.5 billion of Anthropic’s run rate sits inside Claude Code alone, a single command-line product launched in May 2025.
• 900 million weekly active users for ChatGPT against tens of millions for Claude on the consumer side.

The Coding Lane Holding the Valuation Up

If you strip Anthropic down to one engine driving the $900 billion math, it is Claude Code. Claude Code was made available to the general public in May 2025, and its run-rate revenue has grown to over $2.5 billion, more than doubling since the beginning of 2026. Business subscriptions to the product have quadrupled since the start of the year, and enterprise use has grown to represent over half of all Claude Code revenue.

The product also wins where word of mouth lives. JetBrains’ January wave of its AI Pulse survey, which polled more than 10,000 professional developers worldwide, found that 57% of developers had heard of Claude Code in January 2026, up from 31% in spring 2025, and 18% currently use it at work, a sixfold rise from roughly 3% the previous spring. Its CSAT (customer satisfaction) sits at 91%, and its NPS (net promoter score, a recommendation index on a scale from minus 100 to plus 100) is 54, both category-leading numbers.

Mapped against its rivals, the share picture looks like this:

Sources: JetBrains AI Pulse (January 2026), Microsoft FY26 disclosures, vendor figures. The Pragmatic Engineer’s February survey of roughly 900 senior engineers tells a similar story: when professional developers pick the tool they like most, the gap is not close.

That concentration matters because coding is not a niche inside enterprise AI. It is the category. Menlo Ventures data shows coding now accounts for 51% of all generative AI enterprise usage, by a wide margin the highest-value use case in the market, and within that segment Anthropic holds 42 to 54% market share. A $900 billion price tag for Anthropic is, in large part, a price tag for owning that lane.

Where the $30 Billion Comes From This Time

The investor list on this round is what makes it unusual. Anthropic’s previous $30 billion Series G in February closed at a $380 billion post-money valuation, led by GIC and Coatue, with co-leads including D. E. Shaw Ventures, Dragoneer, Founders Fund, ICONIQ and MGX. The current round, if it closes as reported, brings in a different anchor group.

Per the Financial Times reporting underpinning the $900 billion figure, the lead investors stepping in are:

• Dragoneer Investment Group, returning from the February round as a co-lead.
• Greenoaks Capital Partners, the San Francisco crossover firm.
• Sequoia Capital, one of Anthropic’s earliest backers.
• Altimeter Capital, the public-and-private hybrid fund run by Brad Gerstner.

Each of those firms is in for $2 billion or more, according to the FT. Amazon and Google, both of whom anchored the February round, are not expected to participate this time. Some early backers, particularly those who invested in 2024 or earlier, are skipping this round and are instead waiting to potentially cash out during Anthropic’s anticipated IPO later this year, as the company raises what is likely to be its last private round before going public to fund its massive computing needs. The capital push comes as the San Francisco-based company explores a potential initial public offering as early as October.

Compute Is the Other Half of the Story

If Claude Code is the revenue engine, GPU capacity is the constraint. Anthropic spent the past nine months locking in compute deals on a scale that would have been unthinkable for any private company outside the AI lab cohort. The most striking of them landed on May 6, when the company agreed to take over an entire xAI-built supercomputer.

The SpaceXAI compute partnership announcement spells out what Anthropic is getting. Colossus 1 features over 220,000 NVIDIA GPUs, including dense deployments of H100, H200, and next-generation GB200 accelerators, delivering extreme parallel performance for large language models, multimodal systems, scientific simulations, and generative AI at frontier scale. The agreement gives Anthropic more than 300 megawatts of new capacity and access to all of those GPUs within the month.

That deal sits inside a much larger build-out:

• Amazon: up to $25 billion in investment with 5 gigawatts of compute capacity for training and deploying Claude models.
• Google + Broadcom: a separate 5-gigawatt agreement starting next year, plus a Google commitment of up to $40 billion tied to performance milestones.
• Microsoft + Nvidia: a November 2025 partnership in which Anthropic agreed to buy $30 billion in Azure compute capacity.
• SpaceXAI Colossus 1: the entire Memphis cluster, 220,000+ GPUs and 300 megawatts, transferred from xAI’s own Grok training to Anthropic within May.

The compute story also explains why Elon Musk, who has spent two years calling Anthropic “woke” and “misanthropic,” agreed to lease his largest GPU cluster to a direct rival. Musk wrote on X that he was ok leasing Colossus 1 to Anthropic, as SpaceXAI had already moved training to Colossus 2. The economics of AI infrastructure now bend toward the highest-bidder lessee, even when the lessee builds the model your own model is supposed to crush.

OpenAI Owns the Consumer Lane Anthropic Doesn’t

The contrarian read on $900 billion is that it does not yet buy what OpenAI’s $852 billion buys. Anthropic has under 8% of consumer AI traffic, against ChatGPT’s share that, while down from roughly 80% a year ago, still sits north of 50%. A consumer brand at ChatGPT’s scale generates a flywheel that an enterprise-first business cannot replicate just by adding GPU capacity.

The broad consumer reach of ChatGPT creates a powerful distribution channel into the workplace, where demand is rapidly shifting from basic model access to intelligent systems that reshape how businesses operate.

That is OpenAI’s own language from its March funding post, and it captures the part of the franchise Anthropic does not have. The consumer install base feeds enterprise upsell. OpenAI says its business side now makes up 40% of revenue (up from around 30% last year) and is on track to reach parity with consumer by the end of 2026. The lanes that Anthropic and OpenAI are pricing at $900 billion and $852 billion respectively are not symmetric; one feeds into the other.

The Anthropic counter is that the enterprise channel is increasingly the more valuable end of the funnel anyway. By the company’s own count on its Series G announcement page, two years ago a dozen customers spent over $1 million with Anthropic on an annualized basis; today that number exceeds 500, and eight of the Fortune 10 are now Claude customers. The number of customers spending over $100,000 annually on Claude has grown 7x in the past year.

The bull case for the $900 billion price tag is that those large-account economics scale faster than chatbot ad revenue. The bear case is that owning the developer lane in 2026 does not yet make you a consumer-AI platform in the way the headlines suggest, and the next OpenAI model release could narrow the coding gap in a single quarter.

The IPO Window That Matters

The financing round is, at this point, a pricing event for an IPO that has not been filed yet. TechCrunch sources have described the current raise as likely Anthropic’s last private round before going public, and the company is reportedly targeting a listing as early as October. OpenAI is sitting on a similar fork, with most analysts now expecting a filing window late this year or early next.

The mechanics inside the next six months will tell more about which valuation holds than any private-market term sheet. Raising significant funds now is viewed as essential for securing the massive computing power required to sustain Anthropic’s growth trajectory, but the same compute commitments that justify a $900 billion price tag also harden the burn. Public-market investors will see the bills the private ones got to look past.

If Claude Code’s $2.5 billion run rate compounds through the back half of the year, and if enterprise revenue keeps doubling, $900 billion will look conservative by the time the prospectus lands. If the lane consolidates and Cursor and OpenAI’s Codex close the satisfaction gap, the IPO will price at a discount to this round, and the investors writing the $2 billion checks today will get to find out what an enterprise-AI valuation looks like when retail does the marking.
