OpenAI may file draft IPO prospectus as soon as Friday, targeting September 2026 listing

冲刺 9 月上市，OpenAI 最快本周五提交 IPO 招股书草案

OpenAI expects to file a draft IPO prospectus as soon as Friday, with Sam Altman setting a September 2026 listing target and the company carrying a private valuation above $850 billion.

Why it matters: HKR-H/K/R all pass: an OpenAI draft IPO filing with a $850B+ valuation and September target is a must-write capital-markets story. It stays below the top band because this is still a single-source expected filing, not the filed prospectus.
