Investors Built $70B OpenAI Revenue Estimate Using Wrong Method; AI Stocks Fell When FT Corrected
OpenAI's revenue was estimated at $70B by investors, but a correction by the Financial Times revealed it was closer to $50B. The discrepancy arose from differing accounting methods between OpenAI and Anthropic. AI-related stocks like Nvidia, Oracle, and Arm Holdings fell on the news. OpenAI's CFO confirmed significant revenue growth, but the correction has implications for its valuation and potential IPO.
