At the start of 2025, Anthropic was a well-funded AI startup. Today, it's closing in on a $1 trillion valuation. Here's what happened, why it matters, and what you should be watching next.
The Round That Broke Every Record
Anthropic just wrapped up a $65 billion Series H, putting its post-money valuation at $965 billion. Read that again, not $965 million, but nearly a trillion dollars, for a private company that didn't exist five years ago.
What makes this even more striking is the speed. Just four months ago, Anthropic raised $30 billion at a $380 billion valuation. In a single quarter, its valuation more than doubled.
Round size | $65B (Series H) |
Post-money valuation | $965B |
Annual recurring revenue | $30–40B (up from $1B in late 2024) |
Claude Code ARR | $2.5B — driving 4% of all GitHub commits |
The Business Behind the Billion-Dollar Headline
The valuation isn't coming from hype alone. Anthropic's revenue has grown roughly 10x per year for three consecutive years - a rate that's essentially unheard of in enterprise software at this scale.
Eight of the Fortune 10 are now paying customers. The number of accounts spending over $1 million a year with Anthropic has gone from about a dozen two years ago to more than 500 today. Demand from institutional investors was intense enough that some were given just 48 hours to commit their allocations, and several put in $5 billion just to get access.
Where This Leaves OpenAI
Until this round closed, OpenAI held the record for the highest private AI valuation ever - $852 billion, set in March 2026. Anthropic has now overtaken it.
That said, this round also signals something broader: institutional money is still flowing aggressively into AI infrastructure, even as profit margins stay thin and a clear path to profitability remains a few years out. IPO advisors from Goldman Sachs, JPMorgan, and Morgan Stanley are already in conversations, with a potential public listing being floated for late 2026 or early 2027.
What Traders Should Pay Attention To
This story has real market implications, especially for anyone watching the IPO pipeline.
Anthropic has locked in 5 gigawatts of AWS compute and 3.5 gigawatts of Google TPU capacity, with that infrastructure coming online in 2027. The company plans to spend around $19 billion on compute in 2026 alone, nearly matching its full-year revenue. Gross margins are sitting around 40%, which is well below what you'd typically see in SaaS. Profitability isn't expected until 2028.
Those are the numbers a company would bring into a public offering at close to a trillion-dollar valuation. Whether public market investors accept that math is the real question.
The IPO Is the Story to Watch
If Anthropic goes public in late 2026 or early 2027 near its current private valuation, it will set the tone for how AI companies get priced on public markets across the board. Interestingly, some early backers are reportedly sitting out this funding round entirely, specifically to wait for the IPO. That's a rare move, and it could suggest they expect the public price to come in lower than today's private valuation.
Keep an eye on the IPO prospectus once it drops, the revenue trajectory heading into the listing, and how OpenAI moves in response.
