In January 2024, Anthropic’s annualized revenue was $87 million. By April 2026, it crossed $30 billion. That trajectory (roughly 345x growth in 27 months) has now put the Claude maker ahead of OpenAI on the two metrics that define the AI race: revenue and valuation.
Bloomberg reported on May 12 that Anthropic is in talks to raise at least $30 billion in a new funding round at a pre-money valuation exceeding $900 billion. Some reports place the final number as high as $950 billion. If the round closes at that level, Anthropic would surpass OpenAI’s $852 billion valuation from its March 2026 mega-round, marking the first time the safety-focused lab has held the top position.
The round is expected to close by the end of May. Investors have been given 48-hour allocation windows, and some early backers from 2024 are reportedly skipping this round entirely, choosing instead to wait for the anticipated IPO expected as early as October 2026.
From $19 Billion to $30 Billion in Six Weeks
The revenue numbers tell the story more clearly than any valuation figure. Here is how Anthropic’s annualized run rate has moved:
- January 2024: $87 million
- December 2024: $1 billion
- December 2025: $9 billion
- February 2026: $14 billion
- March 2026: $19 billion
- April 2026: $30 billion
That March to April jump (from $19 billion to $30 billion in a single month) is the kind of inflection that rewrites competitive dynamics. For context, Salesforce took roughly 20 years to reach $30 billion in annual revenue. Anthropic did it in under three years from a commercial standing start.
OpenAI’s current run rate sits at approximately $24 billion, or about $2 billion per month. Analysts had predicted Anthropic would not cross OpenAI until August 2026. It happened in April.
CEO Dario Amodei described the trajectory as “80x annualized growth,” a figure that sounds absurd until you trace the line from $87 million to $30 billion and realize the math checks out.
Three Engines Behind the Acceleration
Enterprise lock-in. Anthropic now counts more than 1,000 enterprise clients paying over $1 million annually, a figure that doubled in less than two months. Eight of the Fortune 10 are Claude customers. Enterprise revenue accounts for roughly 80% of total revenue, which gives Anthropic a fundamentally different profile than OpenAI, where consumer subscriptions (ChatGPT Plus and Pro) still represent the majority of income.
Claude Code. Launched publicly in May 2025, Claude Code hit $1 billion in annualized revenue within six months. By February 2026, it was generating $2.5 billion ARR. The tool now authors approximately 4% of all public GitHub commits, with projections reaching 20% by year’s end. No single AI developer tool has achieved this kind of adoption this fast. The compounding effect is significant: developers who use Claude Code pull their teams onto Claude’s API, which explains much of the enterprise acceleration.
The Google and Broadcom compute deal. Anthropic announced an expanded partnership with Google and Broadcom to supply multiple gigawatts of next-generation TPU capacity, with infrastructure coming online in 2027. CFO Krishna Rao called it “a continuation of our disciplined approach to scaling infrastructure.” The deal builds on Anthropic’s November 2025 commitment to invest $50 billion in American AI infrastructure, and it ensures Claude will train across three hardware platforms simultaneously: AWS Trainium, Google TPUs, and NVIDIA GPUs.
The Capital Efficiency Gap OpenAI Cannot Ignore
This is the number that should concern OpenAI’s investors. Anthropic is generating more revenue while spending roughly one-quarter as much on model training.
OpenAI projects $121 billion in compute spending by 2028. Anthropic’s total training costs are projected to peak around $30 billion. That 4x efficiency gap translates directly into profitability timelines: Anthropic targets breakeven by 2028 or 2029, while OpenAI does not project profitability until after 2030.
The difference comes down to organizational focus. Anthropic has built its entire business around a single model family (Claude) with a clear enterprise distribution strategy. OpenAI is simultaneously running ChatGPT, an API platform, an advertising business, Operator, a phone hardware project, and an enterprise consulting arm. Each line requires its own infrastructure, sales team, and product investment.
Revenue per training dollar spent has quietly become as important as raw model capability in determining which AI company will survive the transition from venture-funded growth to self-sustaining business. On that metric, Anthropic holds a decisive lead.
The Valuation Progression
To understand what $900 billion means, consider the trajectory:
- Q1 2024: $18 billion
- Q3 2025: $60 billion (Google’s round)
- February 2026: $380 billion (Series G, led by Coatue and GIC)
- May 2026: $900 billion+ (pending)
That is a 50x increase in roughly two years. The February round at $380 billion was itself considered aggressive at the time. Nearly tripling again in three months would be unprecedented for a private company at this scale.
Google has already committed $10 billion at a $350 billion valuation with a conditional $30 billion tied to performance milestones. Amazon invested $5 billion at the same tier, with planned incremental investments up to $20 billion over time. Whether either tech giant participates in the $900 billion round remains unclear, though both have strategic reasons to maintain their ownership positions.
If the IPO proceeds at or above $900 billion, Anthropic would debut as one of the 15 most valuable public companies on Earth, ahead of Visa, JPMorgan, and Samsung. For a company founded in 2021 by a group of former OpenAI researchers, that trajectory has no historical precedent in the technology industry.
What Enterprise Buyers Should Watch
For companies evaluating their AI infrastructure, the revenue flip carries implications beyond investor trivia.
Anthropic’s enterprise concentration means Claude’s product roadmap is shaped by the needs of production deployments, not consumer engagement metrics. Features like extended context windows (1 million tokens in Opus 4.6), the Stainless SDK acquisition for developer tooling, and the Claude for Small Business package (launched May 13 with 15 pre-built agentic workflows and connectors for QuickBooks, Stripe, Slack, and a dozen other platforms) reflect a company building for integration depth over surface-level reach.
OpenAI’s strength remains distribution: 900 million weekly ChatGPT users create a surface area no competitor matches. But distribution and monetization are different problems, and Anthropic’s ability to generate more revenue from a far smaller user base signals that enterprise willingness to pay for AI has reached a new tier.
The question for every CTO and IT director is whether Claude’s trajectory represents a durable advantage or a peak-growth moment that normalizes as OpenAI’s enterprise push (including the recent GPT-5.5 agent model) gains traction. The answer likely depends on Claude Code. At 4% of GitHub commits and accelerating, it is building the kind of workflow lock-in that made AWS dominant in cloud computing a decade ago.
If this round closes at $900 billion, the next milestone is October’s IPO. Whether the public market agrees with a near-trillion-dollar price tag for a company that did not exist five years ago will be the most consequential valuation signal the AI industry has ever produced.
