NEW YORK, May 21, 2026, 19:08 (EDT)
OpenAI moved closer to a public listing this week, pushing its private-share price and potential index weight into focus even though the ChatGPT maker still has no public ticker. The company is preparing to confidentially file for a U.S. initial public offering, or IPO — the first sale of shares to public investors — in coming weeks and is aiming to go public as early as September, a source familiar with the matter told Reuters. IPOX Vice President Kat Liu said the end of one legal overhang had “removed a major obstacle to an IPO.” Investing.com
The timing matters. OpenAI, most recently valued at $852 billion, won a key court fight on Monday when a jury ruled against Elon Musk in his lawsuit alleging the company strayed from its nonprofit mission. Reuters reported that the win cleared a potential hurdle to an IPO that sources have said could come as soon as September.
Regular U.S. equity trading had closed by the dateline, and the broader tape gave IPO bankers a usable backdrop. The Dow Jones Industrial Average rose 0.55% to a record close, the S&P 500 gained 0.17%, and the Nasdaq Composite added 0.09%, even as Nvidia fell 1.8% after results.
There is still no official OpenAI stock price. Forge Global said OpenAI is private and has no official ticker, while posting an indicative “Forge Price” of $732.38 a share as of May 21; Nasdaq Private Market, another private-share venue, estimated OpenAI’s share value at $658.94 as of May 7 and said there is no OpenAI IPO price. That spread is the point: these are private-market indications, not live exchange quotes. Forge
Secondary-market trading — private shares changing hands before a listing, usually among employees, early investors and qualified buyers — remains narrow. Nasdaq Private Market says it works with employees, former employees and company investors on sales, and with accredited entities and institutional investors on purchases. Ordinary public investors still cannot buy OpenAI common stock on the NYSE or Nasdaq.
Listed proxies moved as traders looked for ways into the story. The Wall Street Journal reported that SoftBank shares surged 19.8% on Thursday, helped by excitement over OpenAI’s expected IPO and SoftBank’s own energy and data-center plans.
The index angle is new and important. Nasdaq will let some newly listed large-cap companies enter the Nasdaq-100 faster, ranking them by market value on the seventh trading day and, if they qualify, adding them after the 15th trading day. For investors, that means a future OpenAI listing could be pulled quickly into index funds, funds that buy stocks to mirror a benchmark.
Competition is not standing still. Reuters reported Thursday that Anthropic is in early talks to rent servers powered by Microsoft-designed chips, a potential boost to Microsoft’s in-house chip push and another sign the software giant is widening its AI supplier base as its long OpenAI partnership loosens.
OpenAI is trying to show more enterprise depth before the market test. On May 18, the company and Dell Technologies announced a partnership to bring Codex into hybrid and on-premises business systems; OpenAI said more than 4 million developers use Codex weekly, and Dell executive Ihab Tarazi said the deal could help companies “deploy AI where enterprise data already lives.” OpenAI
But the downside case is not small. Reuters Breakingviews cited The Information as reporting that OpenAI projects it will burn $25 billion this year, meaning it will spend far more cash than it brings in, while BNP Paribas analysts estimated the company may not become free-cash-flow positive until 2031. If growth slows, pricing pressure from Anthropic or Google rises, or investors balk at losses, the filing could slip or the valuation could come in below the private-market marks.
The IPO window is also getting crowded. Reuters’ Trading Day column said investors are awaiting potential bumper IPOs from SpaceX and OpenAI, and noted that the two could set the market tone for the rest of the year. OpenAI may be the AI name the market wants. It is also a test of how much loss-making growth public investors will still buy.
The next scheduled NYSE holiday is Memorial Day on Monday, May 25. Until an actual filing lands, the trade is anticipation: private price marks, SoftBank-style proxies, and the question of how fast index money might have to follow.
