Financial Times reported that OpenAI's annualised revenue stood at close to $50 billion as of September, falling short of earlier investor figures pegged near $70 billion.
The discrepancy stemmed partly from counting gross revenue from partnerships like Nvidia to compare metrics against rival Anthropic.
The lower revenue estimate weighed on technology stocks, causing shares of Nvidia to drop 2.9%, SpaceX down 4%, and Oracle down nearly 6%.
