OpenAI will become a public company in 2027, according to CFO Sarah Friar, who communicated the timeline to employees at an all-hands meeting. The announcement settles a reported internal split between Friar, who advocated for a 2027 listing at around a trillion-dollar valuation, and CEO Sam Altman, who pushed for a 2026 debut.
The company’s confidential S-1 was submitted to the SEC on June 8, 2026. However, the public prospectus has not yet appeared on EDGAR and must be published at least 15 days before any roadshow. The 2027 commitment suggests the more cautious timeline prevailed, likely to allow for additional preparation and perhaps more favorable market conditions.
Separately, OpenAI published figures on safety costs at the frontier. Monitoring overhead now runs approximately 20 percent of the inference compute being monitored, covering all reinforcement learning training and tool-involving evaluations for GPT-5.6 Sol-class models and above, plus all inference on the Astra model. This provides a concrete metric on a question the industry typically addresses only in qualitative terms.
The timing of the IPO announcement comes amid intensifying activity across the AI sector. SpaceX reportedly approached Cognition, maker of the Devin coding agent, about a potential acquisition and compute partnership — just days after closing a reported $60 billion deal for Cursor. Meanwhile, Nvidia is in talks to invest in Mercor at a $20 billion valuation, roughly double the company’s valuation from nine months ago.
These developments paint a picture of accelerating consolidation in the AI infrastructure layer. The company being valued at $20 billion — Mercor — does not build models but labels data for those who do, highlighting where bottlenecks remain in the supply chain.
The IPO will mark one of the most anticipated public offerings in technology history, with implications extending beyond OpenAI itself to shape how frontier AI companies approach public markets.
