Is the AI bubble about to pop? Sam Altman is prepared either way.

OpenAI CEO Sam Altman warns that investors are overexcited about AI, predicting someone will lose a "phenomenal amount of money" in what he compares to the dot-com bubble. This comes as OpenAI seeks a $500 billion valuation, up from $300 billion months earlier. Meanwhile, new MIT research shows 95% of enterprise AI pilots fail to deliver rapid revenue acceleration, though purchased AI tools succeed 67% of the time compared to internally built systems. The failures are attributed to implementation problems and learning gaps rather than AI model quality itself.
