Morgan Stanley warned on October 5, 2026, that a worsening U.S. data-center power crunch is now hitting the chip supply chain — but Nvidia and Broadcom are relatively insulated. The brokerage estimated last month that U.S. data-center developers face a 34 percent net power shortfall through 2028, equivalent to roughly 32 gigawatts, even after accounting for behind-the-meter generation and fuel cells. If chip capacity cannot be deployed because the power is not there, customers could push out deliveries or cancel orders — and the pain concentrates in memory, optical, power-management, and analog components.
The two giants escape the worst of it, Morgan Stanley said, because of their visibility into chip placement, geographic expansion, and coordination across data centers, semiconductor suppliers, and the power supply chain. The bank does not see the bottlenecks putting Nvidia's or Broadcom's 2027 forecasts at risk. Goldman Sachs has also flagged mounting constraints on the U.S. data-center buildout, while expecting limited near-term impact from political pushback; Morgan Stanley sees labor, power, and political challenges together.
The exposed middle layer is the interesting part. Secondary components — the DRAM and NAND that ride alongside accelerators, the optical transceivers that stitch racks together, the power-management and analog chips that condition current — face inventory disruption when deployments stall. They lack the direct placement visibility that protects the two flagship vendors, so a delayed data center ripples backward into their order books first. That is the same memory supply chain already rattled by record demand and the new labor unrest at Micron's Taiwan operations.
For enterprise infrastructure planners, the message is that the AI buildout's binding constraint is moving downstream from silicon to the grid. Capex planning for 2027 and 2028 now has to model power availability as a gating factor — not just chip lead times — and procurement teams should watch for deployment-driven order pushouts that have nothing to do with vendor execution. Behind-the-meter generation, fuel cells, and site selection near assured power are becoming line items in infrastructure strategy rather than footnotes.
The broader read: the industry spent two years solving chip supply and is now discovering the next bottleneck is electrons. Investors responded by sorting the winners from the exposed — a sorting exercise enterprise buyers can use too, by mapping which suppliers have placement visibility and which are riding the secondary-component inventory wave.
