OpenAI disclosed that its annualized revenue reached $50 billion at the end of September, correcting the earlier $68 billion estimate that had included gross revenue from partner channels. The company reported a 77 % quarter‑over‑quarter run‑rate increase for total revenue and a 107 % increase for its enterprise business during the third quarter. Despite the lower revenue, OpenAI maintains an $852 billion valuation and is preparing for a 2027 initial public offering after filing a confidential prospectus in June. The firm is also in early discussions for a new financing round that could raise approximately $30 billion, following a historic $122 billion close in March, and CFO Sarah Friar asserts the balance sheet remains robust. Market reaction was immediate: Nvidia shares slipped 3 %, Oracle 6 %, CoreWeave 8 %, while AMD, Broadcom, Intel and Super Micro fell 4‑5 % each. OpenAI’s safety concerns, including the withdrawal of GPT‑6.1 Astra, have delayed its IPO timeline, whereas rival Anthropic reports a $65 billion revenue run‑rate and pursues a $2 trillion valuation.
