OpenAI Files Confidential S‑1 as It Joins Anthropic in Race to Go Public

The filing preserves an option to raise public capital, sets the stage for audited financial disclosure, and invites closer investor and regulatory scrutiny.

Overview

  • OpenAI confirmed in a blog post that it confidentially submitted a draft S‑1 to the SEC, a step that gives the company the choice to pursue an IPO without immediately disclosing detailed financials.
  • Anthropic submitted its own confidential IPO paperwork a week earlier, creating a direct competition for public capital and a near-term benchmark for how the market may value frontier AI firms.
  • OpenAI told reporters it has not set timing and said it 'may be a while,' even as news reports link major banks such as Goldman Sachs and Morgan Stanley to the deal and some analysts project possible listings later this year.
  • A recent jury decision that dismissed key claims by Elon Musk removed a legal overhang that had worried investors, but OpenAI still faces large infrastructure spending, reported missed internal targets, and intensifying competition from Anthropic and Google.
  • If OpenAI and Anthropic move to public markets, their audited filings will offer the first apples‑to‑apples view of frontier AI economics, a shift that could reprice private valuations, draw heavy investor capital away from smaller deals, and increase pressure on product, governance, and safety choices.
