3 US AI Infrastructure Stocks Worth Watching As Data Center Spending Rises
Interest rates are climbing, cash is suddenly earning something again, and yet AI spending and data-center buildouts keep pulling capital like a magnet. That mix creates a strange tension for investors. Money is no longer free, but the AI story has not gone quiet. This article explains how that backdrop ties into US Artificial Intelligence & Data Center Infrastructure Stocks and examines three stocks exposed to this rate shock and AI capital expenditure theme.
The stocks highlighted below are just a small sample, and the full screen surfaced 32 more US Artificial Intelligence & Data Center Infrastructure companies with equally compelling stories that are not covered here. To go straight to the broader opportunity set, use the US Artificial Intelligence & Data Center Infrastructure Stocks screener to identify, filter, and analyze the highest conviction ideas that fit your own approach.
MACOM Technology Solutions Holdings (MTSI)
Overview: MACOM Technology Solutions Holdings designs analog semiconductors that move data at high speeds for AI data centers, telecom networks and defense systems.
Operations: MACOM generates about US$1.16b from designing, developing, manufacturing and marketing semiconductors and modules, with key customers across the United States, China and wider international markets.
Market Cap: US$19.23b
MACOM Technology Solutions matters for this AI and data center screen because its analog chips help move huge volumes of information between servers, switches and optics. This directly connects its fortunes to how aggressively hyperscalers keep building out high speed connectivity.
"Heavy dependence on 800G and 1.6T optical deployments, including 200-gig per lane photonics, leaves MACOM exposed if hyperscaler build schedules or module ramps slow."
The real swing factor is how one less obvious bottleneck in AI data center buildouts ultimately shapes MACOM’s pricing power and earnings trajectory.
That bottleneck is exactly what the full narrative for MACOM Technology Solutions Holdings unpacks. It shows where pricing could accelerate, where demand might stall, and how hyperscaler behavior could reshape MACOM’s runway.
MongoDB (MDB)
Overview: MongoDB runs a general-purpose database platform that supports modern cloud, data-heavy and AI-enabled applications across enterprises worldwide.
Operations: MongoDB generates about US$2.78b from data processing software and related services across customers in Asia Pacific, EMEA and other regions.
Market Cap: US$30.32b
MongoDB matters in an AI and data-center context because its Atlas cloud service and related tools handle the heavy data lifting underneath many AI-enabled workloads.
"The exponential growth of data from digital transformation and AI initiatives is increasing demand for MongoDB's scalable, flexible platform, as evidenced by strong customer uptake among large enterprises and new AI-native companies."
The real swing factor now is how one unresolved pressure around AI-driven Atlas usage shapes the balance between future demand and profitability.
That pressure point is exactly what the full narrative for MongoDB unpacks, revealing where accelerating AI workloads could decouple Atlas growth from margins and what risks might be getting overlooked.
Flex (FLEX)
Overview: Flex builds and manages complex hardware, power and cooling systems that underpin AI data centers and global communications infrastructure.
Operations: Flex generates about US$7.19b from Cloud and Power Infrastructure, US$11.61b from Integrated Technology Solutions and US$10.47b from Regulated Manufacturing Solutions.
Market Cap: US$39.86b
Flex matters for this AI and data center screen because it handles the physical side of AI growth, from dense server racks to power and cooling gear that keeps hyperscale facilities running.
"The CPI Spin-Off Announcement (May 2026): Flex unveiled a transformative plan to separate into two independent, public entities by spinning off its Cloud & Power Infrastructure (CPI) division. By isolating this high-growth AI infrastructure engine (spanning liquid cooling, critical power, and server rack integration), management aims to eliminate the "conglomerate discount" that has historically suppressed Flex’s stock valuation."
The real swing factor is what happens to Flex’s earnings power if a single assumption about AI data center hardware demand or power needs breaks.
If that assumption matters to you, read the full narrative for Flex to see how AI demand, margins and capital intensity could be evolving beneath the headline story.
