Global AI stocks fell Monday after top AI leaders endorsed slowing down the development of frontier models.

Microsoft joined OpenAI, Anthropic, and SpaceXAI on Monday in endorsing a more prudent approach, raising investor fears that less compute spend could dampen the investment boom driving a global rally.

While OpenAI has ruled out an IPO this year, Anthropic is moving ahead, informing investors it expects a second straight profitable quarter.

“The competitive race between companies and countries remains intense, and it’s difficult to imagine firms voluntarily ​stepping back while rivals continue to push ahead,” Deutsche Bank analysts wrote. “We have to keep developing,” Microsoft’s Mustafa Suleyman said. “We just have to do it with a little bit more caution and care.”
