Anthropic's S-1 vs OpenAI's Silence: What Is Public

Anthropic now discloses revenue, losses, compute commitments and headcount. OpenAI discloses none of it.

Until 26 October, every figure about frontier-lab economics was an estimate. Anthropic's S-1 changed that for exactly one company. OpenAI remains private, with no filing in public view and a 2027 window.

What the disclosure actually changes

The single most useful line is Q2 operating income of $974 million, against a $1.7 billion operating loss in Q1. That is the first evidence from any frontier lab that the unit economics can turn positive at scale, and it is checkable rather than briefed.

The second is the compute obligation: up to $120.5 billion under arrangements running into 2029, roughly $3.1 billion a month once capacity is fully delivered, expected December 2026. That is a cash commitment, unlike the convertible-note charge, and it is the number that decides whether the operating profit holds.

Why the comparison is uneven on purpose

Every OpenAI figure in circulation - revenue run-rates, valuations, loss estimates - comes from reporting on private conversations. Those may be accurate. They are not the same category of information as a document filed with a regulator under liability. When OpenAI files, this table can be completed. Until then the right reading is that one company's economics can be audited and the other's cannot.

⚖ Our Verdict

Anthropic is now the only frontier lab whose economics can be checked rather than estimated.
