OpenAI is accelerating plans to go public, setting up a high‑stakes Wall Street showdown between rival visions of the AI future and raising questions about whether investor enthusiasm is outrunning the business fundamentals.

In March 2026, OpenAI closed a massive funding round that pushed its post‑money valuation to about $852 billion, paving the way for a public listing that would give early backers a chance to cash out and bring in yet more capital for AI infrastructure. By April, reporting suggested the company could seek to raise at least $60 billion in an eventual IPO, with some analysts predicting a valuation of up to $1 trillion once shares hit public markets.

Momentum sharply increased in May. On Monday, a jury in Oakland, California, rejected Elon Musk’s claims challenging OpenAI’s shift to a for‑profit structure, finding they were barred by statutes of limitations. Rejuvenated by the courtroom win, OpenAI moved “to go public this fall,” targeting a September listing and working with Goldman Sachs and Morgan Stanley on filings, according to people familiar with the matter. TechCrunch described the company as “barrel[ing] toward IPO that may happen in September.”

Around the same time, Axios reported OpenAI was preparing a confidential IPO prospectus that could be submitted to regulators “shortly,” though the “timing remains fluid,” with the plan appearing calibrated against SpaceX’s imminent public debut using many of the same banks. An OpenAI spokesperson framed the effort cautiously: “As part of normal governance, we regularly evaluate a range of strategic options. Our focus remains on execution.”

Externally, supporters highlight OpenAI’s dominance—ChatGPT accounts for 54% of generative‑AI traffic and more than 900 million weekly active users—arguing a trillion‑dollar IPO could define the GenAI era. Internally, the company is courting startups with aggressive incentives, with president Greg Brockman touting “$2M in API credits in every @ycombinator startup in the current batch” to power “the next generation of startups.”

Skeptics, however, warn that OpenAI is “still burning more cash than it is bringing in” and has reportedly missed revenue targets, feeding broader concerns at institutions like Bank of America about a looming AI bubble even as OpenAI, SpaceX and Anthropic all race toward market‑defining IPOs.
