Nvidia signs MOUs with six Wall Street firms to mobilize over $500 billion for AI infrastructure

A growing roster of investors, strategists and industry leaders are warning that the artificial-intelligence boom may be nearing a breaking point, with concerns shifting from the debt and interest rates funding massive data centers to the technology's potential for catastrophic harm. Ray Dalio said the bubble is nearing the point where it may burst because rising interest rates and increased borrowing to fund the AI infrastructure buildout create a need for cash, while strategist Joachim Klement said his core conviction is that the AI bubble will burst in 2027 or 2028. Michael Burry has taken short positions against Nvidia, Oracle, Palantir, Nebius, Micron and CoreWeave, arguing that enormous capital spending might not translate into durable returns, and Galaxy Digital CEO Michael Novogratz called it the biggest bubble of our lifetime while advising investors to ride the wave. OpenAI CEO Sam Altman said investors as a whole are overexcited about AI, and Sequoia's David Cahn put the annual gap between AI infrastructure spending and ecosystem revenue at nearly $600 billion, saying the bubble is reaching a tipping point. Anthropic CEO Dario Amodei called for slowing the pace of AI model improvements, with OpenAI's Sam Altman and SpaceX founder Elon Musk agreeing, after Anthropic insider Evan Hubinger put his personal estimate of the probability that AI could kill all humans at more than 10% within the next decade.

Prologis's Texas data center venture with Skybox Datacenters ran into uncertainty in late September 2026 after new statewide limits on large power grid hookups raised questions about the Hutto project's timing, scale and potential rental income. The restrictions introduce project-specific uncertainty for the Hutto data center but do not materially change Prologis's near-term earnings catalyst, which still rests on lease-up, rent resets and integrating development profitably. A cluster of UK Takeover Code disclosures showed TIAA, Charles Schwab Investment Management and Dimensional Fund Advisors each reporting more than 1 percent stakes in Prologis, as the company raises equity and pursues the potential US$18.8 billion to US$19 billion SEGRO acquisition. Prologis's narrative projects $10.4 billion revenue and $3.6 billion earnings by 2029, requiring 2.5% yearly revenue growth but a decrease of about $0.6 billion in earnings from $4.2 billion today. Three Simply Wall St Community fair value estimates for Prologis span roughly US$126.95 to US$158.23, with the published forecast implying a $158.23 fair value, a 22% upside to its current price.
