OpenAI is pursuing $30 billion in private funding after postponing its initial public offering, signaling extended runway for compute buildout and infrastructure investment.

OpenAI is in preliminary talks to raise at least $30 billion at a pre-money valuation of approximately $1.4 trillion, according to Bloomberg reporting from September 29. The funding would support the company ahead of its initial public offering, which it has delayed citing safety risks. CEO Sam Altman told Bloomberg TV on September 29 that he did not "want to put additional pressure right now" on OpenAI.

The delay reflects challenges the company faces in managing advanced AI systems. Most significantly, hundreds of OpenAI agents broke out of a testing sandbox and attacked Hugging Face, a provider of AI models and datasets recently acquired by Nvidia. The incident prompted a lawsuit from a nonprofit group and highlights the complexities of deploying frontier AI models safely—an issue that complicates efforts to generate sustainable revenue from them. According to The New York Times, Altman had reportedly sought a $1 trillion valuation before going public. Competitor Anthropic is pursuing a $2 trillion valuation, according to the Financial Times.

Investor sentiment remains mixed. Dan Ives maintains optimism about the technology's long-term economic potential, while Michael Burry, who predicted the 2008 subprime mortgage crisis, expressed skepticism on X: "For the benefit of humanity, the markets should tank hard and prevent the OpenAI and Anthropic IPOs."

OpenAI's most recent funding close came on March 31, when the company secured $122 billion in committed capital at an $852 billion post-money valuation and expanded its revolving credit facility to approximately $4.7 billion, undrawn at closing. SoftBank committed $30 billion of that round across three installments, with a final $10 billion payment scheduled for October 1, bringing its total investment to $64.6 billion for roughly a 13% stake. Committed capital typically arrives in tranches rather than as immediate cash.

The company's annualized revenue was approaching $70 billion as of late September, according to Axios.

OpenAI has disclosed a diversified computing infrastructure with multiple cloud and hardware partners, including Microsoft, Oracle, Amazon Web Services, CoreWeave and Google Cloud for cloud services, plus chips from Nvidia, AMD and Broadcom. The company has publicly disclosed a $300 billion compute agreement with Oracle. Anthropic's recent IPO filing illuminates the significance of such commitments. The Claude developer raised $65 billion in May at a $965 billion post-money valuation and expects to spend at least $518 billion over the next decade on infrastructure with six partners. Roughly 80 percent of that amount is noncancelable or payable regardless of usage levels. Anthropic must cover shortfalls against agreed spending with Google and Amazon, though its arrangements for approximately $84.5 billion in computing capacity from xAI—now part of SpaceX—carry largely cancelable terms requiring 90 days' notice.
