Both frontier AI labs are racing to public markets behind confidential filings, and neither has opened its audited books. Anthropic filed a confidential S-1 with the SEC on June 1, days after raising $65 billion at a $965 billion post-money valuation, and could list on the Nasdaq as early as October. [1] It reports a run-rate revenue that crossed $47 billion — up from roughly $10 billion in annual revenue a year earlier — a claim, not audited disclosure. [2] OpenAI filed its own confidential S-1 on approximately June 8 and now leans toward delaying a listing to 2027.

The paper's July 7 account of both labs racing to market before disclosure rules bite held that AI capital stays inside filings and reviews before the public sees the books. Today the two clocks are visibly diverging — Anthropic holding an October target, OpenAI drifting toward 2027 — and both remain sealed.

On X, it is a horse race: which lab prices first, which valuation holds, whether a mega-listing whipsaws Nvidia and the rest of the chip trade. MSM runs each filing as a milestone with a how-to-buy explainer attached. The paper's middle is disclosure timing. Two of the largest offerings in history are being priced on unaudited run-rate claims — Anthropic's own reporting notes its $30-billion run rate may have overtaken OpenAI, making the latter's $850 billion mark "difficult to justify." [3] The run-rate that justifies a near-trillion-dollar tag is inseparable from the data-center spend behind it, and the compute bill is exactly what the sealed filing keeps out of view.
