The company behind ChatGPT is laying the groundwork for what could become one of the largest stock market debuts in history, with reports suggesting OpenAI is preparing for an initial public offering valued at up to $1 trillion. The move would mark a defining moment for the artificial intelligence sector and cap a year already shaping up to be a blockbuster for US listings.
According to reports, OpenAI has begun preliminary discussions with Wall Street banks about launching an IPO as early as the fourth quarter of this year. The San Francisco-based group, led by chief executive Sam Altman, has simultaneously been strengthening its internal financial infrastructure, hiring Ajmere Dale as chief accounting officer and Cynthia Gaylor as corporate business finance officer, with responsibility for investor relations. The steps are widely seen as early signals of serious public market ambitions.
If it proceeds, OpenAI would join a growing cohort of high-profile technology companies preparing to test investor appetite for mega-valuations. Elon Musk’s SpaceX and OpenAI rival Anthropic are both reported to be exploring listings, as enthusiasm around artificial intelligence, space technology, and next-generation infrastructure drives renewed confidence in equity markets.
Musk is said to be targeting a mid-June flotation of SpaceX, timed to coincide with a rare planetary alignment and shortly before his birthday. The rocket company is reportedly seeking to raise as much as $50 billion at a valuation of around $1.5 trillion, a figure that would surpass the record set by Saudi Aramco’s 2019 listing. Anthropic, meanwhile, has also held talks with banks about a potential IPO, according to reports.
Altman has previously expressed ambivalence about running a public company, saying in December that while he was not personally excited by the prospect, he could see advantages for OpenAI despite the added scrutiny and pressure. His comments underscored the tension between OpenAI’s origins as a mission-driven research organisation and its evolution into one of the most commercially significant technology companies in the world.
The IPO speculation comes as OpenAI attracts enormous interest from global investors. Amazon is reported to be in talks to invest up to $50 billion in the company, while SoftBank is said to be considering an additional investment of as much as $30 billion. Such backing reflects the scale of OpenAI’s ambitions, particularly its heavy spending on data centres and computing power to support increasingly sophisticated AI models.
The momentum has also reignited tensions with Musk, an early supporter of OpenAI who left the organisation in 2018 after disagreements over its direction. He is now seeking damages of up to $134 billion from OpenAI and its long-time partner Microsoft, arguing that he is entitled to gains generated from his early involvement. OpenAI has dismissed the claim as unserious, describing it as part of what it characterises as a broader harassment campaign.
As the AI arms race accelerates and capital floods into the sector, a public listing by OpenAI would not only reshape the company’s future but could redefine expectations for scale, valuation, and influence in global technology markets.
