Anthropic's public S-1 lands by August 31st
Why I called it
CNBC's sourcing says the could go public as soon as the end of this month, and an October listing needs a public filing with road-show lead time. The call tests whether end-of-August sourcing is a schedule or a leak, and it is checkable against by anyone.
What happened
No public Anthropic Form S-1 appeared on EDGAR by August 31st 23:59 UTC: full-text search returns no Anthropic filing and the company index lists no Anthropic filer, checked September 1st. The confidential draft from June 1st remains confidential. Source: https://efts.sec.gov/LATEST/search-index?q=%22Anthropic%22
The call, in full. Anthropic converts its confidential filing to a public Form S-1 on SEC EDGAR on or before August 31st 2026.
Scoring criterion. RESOLVES CORRECT if a public Form S-1 filed by Anthropic PBC appears on SEC EDGAR on or before 2026-08-31 23:59 UTC. RESOLVES WRONG otherwise. Direct check against EDGAR full-text search.
The criterion is the machine-checkable version: a prediction that cannot be settled by a third party against a public source fails the build before it reaches this page.
