OpenAI Preparing for September IPO
TechCrunch reports that OpenAI is preparing to move forward with an initial public offering that CEO Sam Altman hopes could take place by September. The company has been working with Goldman Sachs and Morgan Stanley and — according to the Wall Street Journal — may file IPO paperwork confidentially with regulators within days or weeks. The timing follows a U.S. court ruling that dismissed a lawsuit by Elon Musk which had threatened OpenAI’s structure and finances, a development observers say removes a legal obstacle to a flotation. Media coverage has framed the potential listing as a blockbuster: some reports cite expectations of a valuation above $1 trillion, compared with OpenAI’s last private valuation near $850 billion. The possible IPO is occurring amid expectations of near-term IPO activity from SpaceX, now a competitive presence after acquiring xAI.
An OpenAI IPO would be a major, market-moving public offering from a foundational LLM company — affecting valuations, investor appetite for AI, competitive positioning among AI platform providers, and broader technology and advertising ecosystems.

OpenAI confidentially files for IPO
OpenAI announced it has confidentially submitted a draft S-1 registration statement with the U.S. Securities and Exchange Commission, posting the news on X and saying it has not yet decided on timing. The filing follows rival Anthropic’s confidential IPO filing a week earlier and signals the industry’s largest AI startups are preparing for public scrutiny. OpenAI — the maker of ChatGPT, which reports over 1 billion monthly active users — was last valued at more than $850 billion while Anthropic recently raised capital at an implied $965 billion post‑money valuation. The move has been reported to involve investment banks (including Goldman Sachs and Morgan Stanley) and may include a tender offer to let employees sell shares. The filing comes as OpenAI expands monetization efforts (including ads) and after the company prevailed in litigation involving Elon Musk.
OpenAI May Delay IPO to 2027 After SpaceX
OpenAI is reportedly considering postponing its planned initial public offering from 2026 to 2027, according to reporting that cites people familiar with the matter. The company had originally targeted a Q3/Q4 2026 debut but advisers warned last week of weak retail demand amid recent market turbulence and technology stock declines. Insiders say CEO Sam Altman is aiming for a $1 trillion valuation and is reluctant to lower that target. The SpaceX IPO — which saw its share price fall substantially after an initial high — is cited as a cautionary example. A spokesperson for OpenAI declined to comment, per the report.
OpenAI Files Confidential S-1 for IPO
OpenAI filed a confidential draft registration statement with the U.S. Securities and Exchange Commission to pursue an initial public offering, the company announced on 2026-06-08. The move follows rival Anthropic’s recent IPO filing and intensifies a high-profile race to the public markets that also includes SpaceX. OpenAI was last reported valued at $852 billion post‑money and in late March raised $122 billion in a funding round (including $3 billion from retail investors). The company has signalled large future compute and cash‑burn projections (including plans to spend roughly the same amount on computing power in 2028 and an $85 billion projected burn in that year). The filing discloses no share count or price guidance. The announcement comes amid internal governance history and multiple lawsuits involving OpenAI and its leadership.
