Anthropic Confidentially Files for IPO — $965B Valuation Plus $36B Chip Deal
The funding round still under negotiation in early May has closed — and Anthropic is going a step further: the company has closed a round of $65 billion at a post-money valuation of $965 billion and, on June 1, 2026, confidentially filed for an IPO. That puts Anthropic nominally above OpenAI (last at $852 billion) for the first time. In parallel, Apollo and Blackstone are arranging a debt deal of roughly $36 billion to finance Google TPU chips — according to Bloomberg, possibly the largest chip-financing deal ever.
What's now confirmed
- $65 billion in fresh capital (Series H), post-money valuation $965 billion — above OpenAI for the first time.
- Confidential IPO filing on June 1, 2026; a listing would be possible no earlier than fall 2026.
- Q2 revenue projected by investors at ~$10.9 billion (more than doubling vs. the prior quarter); annualized run rate said to surpass $50 billion by month’s end.
- $36 billion debt deal (Apollo, Blackstone) to buy Google TPUs that Anthropic leases; Broadcom backstops the largest tranche.
What applied before
In early May, the Financial Times, CNBC, and TechCrunch consistently reported that Anthropic was negotiating a $50 billion round at a $900 billion to nearly $1 trillion valuation — at the time explicitly marked as not yet final. We put that in context in our news on the $50 billion round: a lot of movement, but a state of negotiation, not a fact.
What applies now
1. The round is larger than negotiated — and closed. The discussed $50 billion became $65 billion, and the valuation landed at $965 billion. That makes Anthropic nominally the most valuable private AI company, just ahead of OpenAI. Co-leads are reported to include Altimeter, Dragoneer, Greenoaks, and Sequoia; participants include Blackstone, Fidelity, and infrastructure partners such as Samsung, SK Hynix, and Micron.
2. The path to the public market begins. The confidential filing is the first formal step of an IPO process — it doesn’t yet disclose numbers and doesn’t commit to a listing. Reports suggest Anthropic could go public ahead of OpenAI, no earlier than fall 2026. The ~$10.9 billion Q2 revenue cited would, if confirmed, be a significant jump — but so far it’s investor communication, not audited quarterly figures.
3. The chips are financed through debt. The $36 billion deal is separate from the equity round: Apollo and Blackstone structure debt to buy Google’s TPU chips, which Anthropic then leases. Broadcom — a co-developer of the chips — backstops the largest tranche (around $25 billion), keeping financing costs down. According to Bloomberg, it would be one of the largest private-credit transactions ever.
Context
Three reports, one logic: Anthropic is financing itself on several levels at once — equity for the valuation, debt for the compute, IPO preparation for the next stage. What stands out is the separation: the expensive, capital-intensive hardware (TPUs) moves into a debt deal instead of burdening the equity balance sheet. This is an increasingly common pattern in the industry — and it shifts risk from equity investors to lenders and backstop providers like Broadcom.
The sober read: a $965 billion valuation and a confidential filing say more about investor expectations than about documented profitability. The revenue and run-rate figures cited come from investor communication around the round; an IPO prospectus with audited numbers isn’t out yet. That Anthropic has “overtaken” OpenAI is also a snapshot of two private valuations, both of which can shift quickly.
What you can do now
If you use Anthropic plans: Financing pressure stays high — a near-trillion valuation has to be justified. Expect continued active pricing and limit adjustments, and keep an eye on token prices.
If you run multi-model: The concentration of the AI stack on two dominant providers is intensifying. Avoid unnecessary model lock-in where a migration would later be expensive.
If you advise clients as an agency: In client conversations, separate the documented facts (round closed, filing submitted, chip deal arranged) from the projected figures (Q2 revenue, run rate). The former are hard; the latter are expectation.
