Tech stocks suffer $180bn sell-off after ChatGPT misses growth targets

Shares in major tech names tied to OpenAI tumbled after reports that ChatGPT missed internal growth and revenue targets, triggering an estimated $180bn hit to market value across several firms. Investors sold holdings in companies with exposure to OpenAI — including Microsoft (MSFT), Nvidia, SoftBank and Oracle — amid concerns OpenAI may struggle to fund large compute contracts and that its IPO prospects could be impaired. The sell-off reflected broader investor anxiety about AI monetization and competition from rivals such as Anthropic and Google, pressuring chipmakers and cloud/infrastructure providers reliant on AI demand.
