OpenAI files confidentially for US IPO, staff told public may come within year

OpenAI confidentially filed for a U.S. initial public offering on June 8, 2026, according to reporting by Reuters and TechCrunch. The company did not disclose the size or terms of the offering. Per reporting by The Information, cited by Economic Times and PYMNTS, CEO Sam Altman told staff he expected the company to go public "within the next year." In a company blog post referenced by TechCrunch, WSJ, and CNBC, OpenAI wrote: "We have not decided on timing yet; it may be a while because there are things we want to do that are likely easier as a private company."

A U.S. IPO typically begins with a confidential draft registration (S-1) submitted to the SEC, which lets companies negotiate structure with underwriters before a public filing. Reuters and TechCrunch place OpenAI's confidential submission in the same procedural category as Anthropic's filing from June 1. For ML and infrastructure teams, a public listing typically increases demands for quarterly financial disclosure and may change how firms communicate product roadmaps and compute spending to investors.

Reuters reports the filing could target a valuation up to $1 trillion. OpenAI's filing arrived a week after rival Anthropic filed confidentially on June 1, and both are proceeding as SpaceX runs its own IPO roadshow - creating a concentration of major AI-related public offerings in the same market window. WSJ, The New York Times, and CNN frame the wave of filings as a test of investor appetite for capital-intensive AI businesses, and note management teams will face Wall Street questions on growth, margins, and capital expenditure every quarter.

Key indicators:

• •whether OpenAI converts the confidential filing to a public S-1 and when, with some outlets reporting a possible debut as early as September 2026
• •disclosed revenue, margins, and capital-expenditure projections
• •any governance or share-class disclosures affecting voting and control
• •language on model safety, data usage, and third-party compute contracts
• •how other AI listings price and perform, which will set valuation comps

OpenAI's blog statement and the staff remark reported by The Information are the primary public signals to date. The company has not published a public timetable beyond the confidential submission. Market reaction and the details in any eventual public S-1 will determine how materially the filing changes the operating environment for AI research and product teams.
