OpenAI counts $50 billion in revenue, not $70 billion, and chip stocks fall 3.4%

OpenAI has told its investors that its revenue is running more than a quarter below the figure the market had been carrying. No sales vanished: the gap comes from how the sales are counted. That was still enough to send chipmakers from Nvidia to SK hynix sharply lower in a single session, after the Financial Times reported the number and CNBC confirmed it. That reaction is the story for anyone who does not own a piece of OpenAI, which is almost everyone. The data centres, power contracts and chip orders behind the AI boom are justified by a handful of private-company figures, and those figures feed straight into the stocks that dominate index funds and retirement accounts.
