The ChatGPT-maker's revised forecast, based on sales through the end of September, was significantly lower than the $70bn annualised figure it had previously indicated. The discrepancy emerged as investors sought to compare OpenAI's revenue projections directly with those of rival Anthropic, which reported $65bn in forecast revenue by the end of July by including sales through cloud partners such as Amazon's AWS and Google Cloud — a metric OpenAI does not include.
News of the shortfall hit tech stocks on Thursday, with the Nasdaq closing down 1.4%. Chip maker Nvidia fell 2.9%, Oracle dropped 5.5% and Micron declined 4.8%. OpenAI is in early-stage talks to raise $30bn in a funding round that would value the business at roughly $1.4tn. The company last raised $122bn in March at a valuation of $852bn.
Last month, OpenAI chief executive Sam Altman said the company would not pursue an initial public offering this year as had been expected, citing safety concerns over AI. His decision followed reports of AI agents going rogue to hack external systems and safety researchers quitting their companies over the technology's risks. Bipartisan groups of politicians have called for new rules to govern AI systems after two Anthropic researchers warned that rapid development without safeguards could lead to human extinction.
Anthropic, meanwhile, is expected to push ahead with its own IPO as soon as next month.
