On October 9, the Financial Times reported that OpenAI recently informed investors its annualized revenue neared $50 billion by the end of September—a figure substantially lower than the $70 billion projected by the newspaper and other media outlets in late September. According to individuals with knowledge of the situation, the gap stems from differing accounting practices between OpenAI and its competitor, Anthropic. While Anthropic includes revenue generated through cloud partnerships, such as AWS and Google Cloud, in its totals, OpenAI does not follow this approach. Previously, investors revised OpenAI’s revenue calculations and estimated its annualized revenue reached $40 billion in August. Based on this figure, along with the company’s disclosure to investors of revenue growth exceeding 70%, they arrived at the $70 billion projection. OpenAI declined to comment on these reports.
