AI infrastructure spending is colliding with a jump in the US 10-year yield toward 5%, and that mix is shaking up how investors think about capital-heavy stories. Higher discount rates and pricier debt are forcing a sharper test of which projects might justify their cost. This article walks through three stocks exposed to that theme and shows how each could be positioned as rates, politics and AI ambitions pull in different directions.
The three stocks in focus are simply an entry point, while the full screen surfaced 62 more US-listed, capital-heavy AI infrastructure enablers with equally compelling stories that are not covered here.
To identify, compare, and analyze potential high-conviction candidates for your watchlist, go straight to the US Capital-Intensive AI Infrastructure Enablers screener .
Axcelis Technologies (ACLS)
Overview:Axcelis Technologies designs and services ion implantation and related semiconductor fabrication tools that chipmakers use to build AI and data center focused processors.
Operations:Axcelis Technologies generates about US$866 million from manufacturing capital equipment, with revenue sourced from Europe and the Asia Pacific regions.
Market Cap:US$3.1b
Axcelis Technologies matters for this screener because its ion implantation tools sit directly in the semiconductor fabs that supply AI servers, so small shifts in chip capital spending can have an outsized effect on its order book and earnings power.
"Adoption of silicon carbide power devices in electric vehicles and industrial applications remains early stage, with penetration rates and silicon carbide content per vehicle still expected to rise globally and across hybrids, and Axcelis Technologies continuing to point to these applications as highly attractive for future ion implant demand that can support revenue and gross margin over time."
What happens to that margin story will largely depend on how one unseen cost pressure plays out as capacity and orders scale.
Those cost pressures are exactly where the full narrative for Axcelis Technologies shows how Axcelis Technologies could balance capital intensity, pricing power and AI demand at scale.
KLA (KLAC)
Overview:KLA Corporation supplies inspection, metrology, and process control equipment that chip manufacturers rely on to keep AI focused fabs and packaging lines running efficiently.
Operations:KLA generates about US$13.1b from Semiconductor Process Control, US$803 million from PCB and Component Inspection, and US$604 million from Specialty Semiconductor Process.
Market Cap:US$205.8b
KLA matters for this AI infrastructure screen because its tools help determine how much usable output chipmakers actually get from every wafer they push through fabs and advanced packaging lines.
"Rising AI infrastructure and high bandwidth memory investment is lifting wafer equipment demand, and KLA's backlog of around US$12.5b with lead times that extend into 2027 and 2028 supports multi year visibility that can translate into higher revenue and earnings quality."
What that visibility ultimately means for shareholders will depend on how a single cost and pricing squeeze inside this backlog plays out.
That squeeze is exactly where the full narrative for KLA illustrates how KLA could turn backlog, pricing power and AI capex into accelerating earnings quality, while keeping risk firmly in view.
Quanta Services (PWR)
Overview:Quanta Services builds and maintains high voltage power lines, substations, and underground utilities that support AI hungry data centers and large load centers.
Operations:Quanta Services generates about US$30.5b from Electric Infrastructure Solutions and US$6.8b from Underground Utility and Infrastructure, largely across the United States.
Market Cap:US$93.5b
Quanta Services matters for this AI infrastructure screen because it works on the power transmission, substations, and large load centers that keep hyperscale data centers and advanced manufacturing sites supplied with electricity.
"Quanta said large-load customers such as data centers, advanced manufacturing, and industrial customers represented about 10% of total backlog at year-end 2025 and are among the fastest-growing parts of demand."
What really influences how that backlog turns into shareholder value is how one capital intensive push inside those power projects shapes future returns.
That capital push is exactly where the full narrative for Quanta Services shows how Quanta Services could turn heavy grid buildouts into accelerating returns while keeping project and policy risk in check.
