The company is thought to be looking to raise at least $60bn.A stock market float would give OpenAI another route to raising cash, supporting ambitions by the chief executive,Sam Altman, to splash trillions of dollars on building datacentres and other forms of infrastructure needed for the rapid buildout of its chatbots.During a staff livestream on Tuesday, Altman was reported to have said: “I think it’s fair to say it [an IPO] is the most likely path for us, given the capital needs that we’ll have.”An OpenAI spokesperson said: “An IPO is not our focus, so we could not possibly have set a date. We are building a durable business and advancing our mission so everyone benefits from AGI.”AGI stands forartificial general intelligence, which OpenAI defines as “highly autonomous systems that outperform humans at most economically valuable work”.skip past newsletter promotionafter newsletter promotion‘A stomach of steel’: amateur investors ride out dips amid talk of an AI bubbleRead moreOpenAI was founded as a nonprofit in 2015 with a mission to safely build AGI for humanity’s benefit. However, it completed a lengthy restructuring process this week thatturned its main business into a for-profit corporation. While it is still technically controlled by the non-profit entity, the move makes it easier for OpenAI to raise capital while also laying the groundwork for an IPO.The deal also gave Microsoft a stake of about 27% in the for-profit company, with OpenAI valued at $500bn under the terms of the deal. News of the restructuring helped push Microsoft’s valuationabove $4tnfor the first time.OpenAI reportedly posted revenue of $4.3bn in the first half of this year, with an operating loss of $7.8bn, according to the tech news site the Information.The massive valuations will do nothing to allay fears that the AI industry is operating in a bubble. Officials at the Bank of England this month flagged the growing risk that tech stock prices pumped up by the AI boomcould burst, saying equity markets were “particularly exposed should expectations around the impact of AI become less optimistic”.OpenAI’s chief financial officer, Sarah Friar, reportedly told colleagues that the company was aiming for a 2027 listing, according to the sources cited by Reuters, while some advisers said it could come the year before.Explore more on these topicsOpenAIIPOsSam AltmanStock marketsnewsShareReuse this content
