OpenAI Files Confidential Draft S-1 with the SEC
On June 8, 2026, OpenAI published a Rule 135 announcement disclosing a confidential draft S-1 submission to the SEC. The post says 'we have not decided on timing yet; it may be a while'. SEC EDGAR full-text search between 2026-06-01 and 2026-06-16 returns no OpenAI S-1 or S-1/A filing. This is the gating event for any eventual IPO, not the IPO itself — and the public markers that will signal an imminent listing are not on the record as of June 16, 2026.
