3 AI Infrastructure Stocks for Data Center And Power Demand

AI has become a political football again, with Donald Trump dismissing safety rules as a hoax just as big tech voices call for brakes and kill switches. That tug of war keeps pressure on investors to decide which AI exposed stories might benefit from fewer near term rules, and which might not. This article walks through three large cap data center and power infrastructure stocks that sit in the crosshairs of that debate.

The three stocks covered below are only a small sample of what this theme can throw up, and the full screen surfaced 55 more US listed data center and power infrastructure builders with equally compelling stories that are not unpacked here. To see the broader field and identify which AI linked builders line up best with your own thesis, head straight into the US AI-Driven Data Center and Power Infrastructure Builders screener to filter and analyze for your highest conviction ideas.

Dycom Industries (DY)

Dycom Industries has become a key contractor behind the physical networks that let AI data centers move information. The company wires up fiber, power and telecom infrastructure that links hyperscaler facilities to users and utilities across the United States.

Dycom Industries generates about US$6.0b from its Communications segment, with a smaller segment adjustment of US$0.9b, almost entirely in the United States. The stock is valued at roughly US$9.3b in market cap.

"The accelerating buildout of fiber-to-the-home and data center connectivity, driven by surging AI workloads and hyperscaler investments, is creating multi-year, visibility-rich opportunities for Dycom. Dycom remains heavily reliant on a small number of major telecom customers, which leaves it exposed to revenue concentration risk if those customers reduce capital expenditures or shift contracts."

What happens to Dycom Industries if a single, unseen shift in customer spending reshapes the timing of that fast-growing infrastructure work?

That customer swing is only the starting point, and the full narrative for Dycom Industries shows how Dycom Industries could balance concentration risk against accelerating AI infrastructure demand.

ERock (EROC)

ERock gives this screener direct exposure to the power side of AI infrastructure by supplying modular generation that keeps data centers and other critical facilities running when the grid is stretched.

ERock, based in Houston, designs, installs, and operates modular power systems for US commercial, industrial, utility, and data center clients. The company generates about US$162 million from Electric Equipment and has a market value of roughly US$3.5b.

"AI driven load growth and grid constraints are increasing demand for rapid, on site generation, and ERock's 1.7b contracted backlog and production capacity sold out through 2027 and into 2028 create visibility that can support future revenue and EBITDA as projects convert."

What happens to ERock's earnings path if a single key assumption about how quickly that backlog turns into higher margin power projects starts to shift?

If that timing risk is what you keep circling, read the full narrative for ERock to see how ERock’s backlog, margins and AI power demand could be decoupling in plain sight.

MasTec (MTZ)

MasTec is one of the clearest pure plays on the AI infrastructure build, wiring together data centers, power lines and fiber networks across North America for utilities, hyperscalers and telecom operators.

MasTec generates about US$5.6b from Clean Energy and Infrastructure, US$4.5b from Power Delivery, US$3.5b from Communications and US$2.6b from Pipeline Infrastructure, with small eliminations offsetting internal sales. The stock carries a market value of roughly US$19.1b.

For this AI data center and power build theme, MasTec effectively links the server halls to the grid, handling everything from high voltage transmission and substations to fiber and civil work that keeps capacity coming online.

"Rapid acceleration in utility grid modernization, data center build-outs, and renewable energy investment is associated with double-digit revenue growth and record backlog in MasTec's Power Delivery and Clean Energy & Infrastructure divisions."

What happens to MasTec's earnings power if a single assumption about how quickly that record backlog turns into higher margin projects starts to shift?

That backlog conversion question is just the start, and the full narrative for MasTec shows where MasTec’s AI grid build could be accelerating faster than headline earnings suggest.
