Global full-stack AI infrastructure capital expenditure is projected to total $8.9 trillion between 2026 and 2030 (encompassing Gartner’s $7.0 trillion core IT/data-center hardware subset plus $1.9 trillion in civil, grid, and nuclear power buildouts, and aligning with Columbia Business School’s 8-year $10.3 trillion 2025–2032 macroeconomic projection), driving U.S. data center power demand from ~30 GW to 90–118 GW. While conventional semiconductor ETFs expose investors to 100% single-sector chip cyclicality, roughly half of every AI capital expenditure dollar is spent on physical infrastructure: site excavation, high-voltage interior electrical wiring, direct-to-chip liquid cooling, baseload nuclear electricity, and active rack cabling.
By enforcing two strict quantitative guardrails—a Forward P/E ceiling of 29.0x and a PEG ratio below 1.00—this 11-stock basket eliminates overpriced hype stocks and isolates profitable infrastructure monopolies whose earnings are compounding more than 2.5x faster than their valuation multiples.

Trading 49% below its 10-year median P/E (53.02x), NVIDIA commands full-stack AI rack pricing power as its 20-petaflop Vera Rubin NVL72 racks and containerized DSX Pods ramp into full production. A mandatory 3-to-4-year GPU thermal replacement cycle creates a permanent upgrade annuity starting in 2029–2030.
The undisputed N3/N2/A16 wafer foundry and CoWoS advanced packaging monopoly. TSMC wins regardless of whether GPUs (NVDA) or custom ASICs (AVGO) capture marginal compute share, and also fabricates the custom logic base dies for HBM4 memory stacks.
Dominates custom hyperscaler AI accelerators (XPUs for Google TPU and Meta MTIA) alongside high-speed Tomahawk 5/6 Ethernet switch silicon. Positioned as the primary beneficiary of the 2027–2029 shift toward cost-efficient AI inference.
The lowest forward multiple in global AI hardware (3.80x Forward P/E). Protected by its proprietary MR-MUF liquid-epoxy thermal packaging process and direct TSMC logic base-die partnership for 12-high and 16-high HBM4 memory.
The sole U.S.-based manufacturer of HBM3E/HBM4 and high-density enterprise LPDDR5X DRAM. Triple-digit earnings expansion compresses its forward multiple under 5x while CHIPS Act subsidies fund domestic megafabs in Idaho and New York.
Owner of the 2.5 GW Susquehanna nuclear facility co-located with Amazon Web Services (AWS) in the capacity-constrained PJM grid. Captures multi-decade nuclear PPA repricings and rising capacity auction payments at a fraction of peers' valuation multiples.
