SpaceX and Musk's empire are under pressure, which is bad news for anyone betting big on his AI and space promises.

• SpaceX stock dropped sharply, and a steady stream of senior people are quitting, including X's product chief and staff from its AI team.
• Musk claims SpaceX will hit huge revenue milestones by 2030, but banks model only a fraction of that, and his past timelines (like robotaxis) keep slipping.
• The company's pitch is now mostly an AI and cloud-computing story, selling the same compute already offered by Amazon, Microsoft, and Meta.
• The whole AI boom looks stretched: spending is enormous, real returns are thin, and Microsoft's AI sales lean heavily on one customer, OpenAI.
• Google, Meta, and others are also reshuffling AI leadership and pouring money into the space, adding to fears of a bubble propped up by hype and circular deals.

Outlook: If one big tech player pulls back on AI spending without proof of strong returns, it could trigger a broad selloff.
