3 US AI Infrastructure Stocks to Watch as Demand Outruns Supply

AI is no longer a distant theme in tech reports. It is now part of the inflation story the Fed is wrestling with, as AI demand hits faster than AI supply, and that mix could reshuffle winners across U.S. large caps. Investors watching higher-for-longer rates and war-related shocks risk missing moves in plain sight. This article walks through three stocks from our AI Infrastructure & Enablers screener that appear positively exposed to this new backdrop.

The three stocks highlighted next are only a small sample, since the full screen surfaced 35 more large caps with equally compelling AI infrastructure narratives that are not covered here.

To go beyond this short list, head straight into the U.S. Large-Cap AI Infrastructure & Enablers screener to identify, filter, and analyze your own highest conviction ideas across data centers, cloud platforms, and chipmakers.

GLOBALFOUNDRIES (GFS)

Overview: GLOBALFOUNDRIES is a pure-play semiconductor foundry that manufactures wafers for AI chips, accelerators and connected devices powering modern computing.

Operations: GLOBALFOUNDRIES generates its business revenue from semiconductors, with US$6.9b reported from this segment, tying the group tightly to chip fabrication.

Market Cap: US$26.8b

GLOBALFOUNDRIES matters for this AI Infrastructure & Enablers screen because it supplies the wafers that keep data centers, connected cars and networks stocked with the chips they need. That context helps frame how its next phase of demand could look.

"Growing demand for automotive and communications infrastructure chips, driven by higher chip content per vehicle and increased connectivity requirements, is still feeding into GlobalFoundries design wins and multi year revenue opportunities in higher margin markets, which supports the case for continued expansion in revenue and net margins."

What happens to those margin ambitions if a single pressure point on future pricing power or capacity utilization does not break its way?

That pricing risk is exactly where the full narrative for GLOBALFOUNDRIES shows how GLOBALFOUNDRIES could still harness accelerating AI wafer demand, while smaller shifts in mix quietly reshape the opportunity.

Keysight Technologies (KEYS)

Overview: Keysight Technologies builds the hardware and software that lets chipmakers and data center providers design, test, and fine tune complex electronic systems for AI era workloads.

Operations: Keysight generates about US$4.7b from its Communications Solutions Group and US$1.9b from its Electronic Industrial Solutions Group.

Market Cap: US$58.2b

Keysight Technologies matters for this AI Infrastructure & Enablers screen because its test gear and simulation tools sit wherever fast chips, high speed links, and dense data center hardware need to prove they actually work under AI scale stress.

"Adoption of AI across digital infrastructure is now visible in Keysight Technologies reporting, with commercial communications delivering its first US$1b quarter and wireline revenue surpassing wireless in Q3 2026."

The story from here depends on how one less visible shift in the mix between hardware, software, and services ultimately feeds through to margins.

That margin mix question is where the full narrative for Keysight Technologies lays out how accelerating AI test demand, software weighting, and services could reshape Keysight Technologies earnings profile beyond the headline numbers.

Fabrinet (FN)

Overview: Fabrinet builds and assembles high speed optical and electromechanical components that move data inside AI focused data centers and networks.

Operations: Fabrinet generates about US$4.6b in revenue from optical networking equipment, concentrated in components for high speed data communication.

Market Cap: US$13.8b

Fabrinet matters in this AI Infrastructure & Enablers screen because it helps hyperscalers and networking giants push more data through AI heavy server racks without choking bandwidth. This is especially relevant as higher for longer rates and AI driven capex intersect with tight optical supply chains.

"Surging AI related data center optics and DCI demand, with data center revenue at 51% of total and Q4 FY26 DCI products at more than a 1b annualized run rate, points to a multi year build out that could keep Fabrinet’s utilization and data center revenue elevated."

What happens to that picture if a single constraint on customer concentration or component availability shifts the balance on pricing power and margins?

Those concentration and supply swings sit at the center of the full narrative for Fabrinet, which maps where Fabrinet’s AI optics story could accelerate or quietly stall next.

Seeking Fresh Alternatives Before They Run

Fresh breakouts and under the radar momentum rarely stay quiet for long. Use these curated lists before the crowd catches on and pricing power drops, and consider acting promptly.
