AI Needs More Than GPUs. These 3 Stocks Are Building Everything Around Them

The artificial intelligence boom has produced a familiar investing instinct: buy the companies making the GPUs. That approach has paid off handsomely, but it leaves out an increasingly important reality. A GPU is useless without a building to house it, electricity to power it, cooling to keep it running, and a grid connection capable of handling the enormous load. The physical infrastructure supporting AI may ultimately prove just as consequential as the chips doing the computing.

That creates a different group of winners. Eaton (NYSE:ETN | ETN Price Prediction), Vertiv (NYSE:VRT), and Quanta Services (NYSE:PWR) sit at different points along that infrastructure chain. They are the picks-and-shovels companies supplying the electrical systems, cooling equipment, and construction expertise required to turn AI spending into actual data centers.

Eaton Has a 15-Year Pipeline

Eaton may be the clearest example of why investors should look beyond GPUs. The company sells switchgear, power distribution equipment, uninterruptible power systems, and increasingly sophisticated cooling infrastructure: the equipment that allows a data center to turn electricity into computing capacity.

During its Q2 2026 earnings update, Eaton posted record revenue of $8.5 billion, up 21% year over year, with 14% organic growth. Management confirmed the company’s U.S. data center backlog had reached 307 gigawatts (GW), equivalent to 15 years of work at 2025 build rates and up from 12 years in the prior update. Only about 20% of that backlog is expected to convert in the near term, with most deliveries extending into 2028 and beyond. Following the strong first half, the company raised its full-year organic growth guidance to an 11% to 13% range.

That distinction matters. The 307-GW figure is not 307 GW of data centers under construction. Industry trackers have reported development pipelines in roughly the 250-GW to 330-GW range, and projects still face years-long grid interconnection queues, permitting delays, labor shortages, equipment lead times, and financing hurdles. Eaton has also deepened its position in the buildout by closing the Boyd Thermal acquisition earlier in 2026, adding liquid-cooling capabilities that extend its reach from the substation all the way to chip-level thermal management.

For Eaton, however, all of that converts into something investors value: multi-year visibility backed by a record order book.

Vertiv Sits Inside the Data Hall

Moving closer to the GPUs, Vertiv is arguably the most direct pure-play among the three, supplying critical power and thermal-management equipment inside data centers.

Its second-quarter 2026 revenue rose 24% to $3.27 billion, while adjusted EPS increased 60% to $1.52. Adjusted operating margin widened to 22.6%, a gain of 410 basis points from a year earlier, and adjusted free cash flow surged to $925 million. Management attributed a modest revenue miss relative to Street estimates to timing shifts in large, multiphase deployments rather than any softening in demand, and responded by raising full-year revenue guidance to $13.8 billion to $14.2 billion and full-year adjusted EPS guidance to $6.65 to $6.75.

The investment thesis is straightforward. As AI racks consume more electricity, power distribution and cooling become harder engineering problems. Liquid cooling, higher-capacity UPS systems, and advanced thermal management are not optional accessories. They are core computing infrastructure, and Vertiv is one of the few companies with the product depth to address all three at hyperscale.

Quanta Gets the Power There

Quanta Services plays a different role. It is closer to the construction crew than the equipment manufacturer, building transmission lines, substations, and electrical infrastructure that connect massive new loads to the grid.

Its second-quarter 2026 results underscored the scale of that opportunity. Revenue reached $9.56 billion, up 41% from $6.77 billion in the year-ago quarter, while total backlog hit a record $53.4 billion at June 30. Adjusted EPS of $4.24 exceeded consensus by a wide margin, and management raised full-year 2026 revenue guidance to a range of $39.3 billion to $39.7 billion.

That gives investors exposure to the bottleneck that exists before electricity ever reaches the server rack.

Key Takeaway

Investors do not need to pick the winning AI model to participate in AI infrastructure. Eaton supplies the electrical backbone, Vertiv handles critical power and cooling inside the facility, and Quanta connects enormous new loads to the grid.

Valuations have expanded across this group, and not every announced data center will get built on schedule. That is precisely why Eaton’s 307-GW, 15-year backlog matters: AI may eventually encounter a spending slowdown, but the physical infrastructure already on order stretches years into the future. Quanta’s record $53.4 billion backlog and Vertiv’s raised full-year guidance reinforce the same point from different angles.

For investors seeking a broader way to participate in AI than simply chasing the hottest chip stock, these three picks-and-shovels companies offer a different kind of exposure: one anchored in contracted work rather than sentiment.

Editor’s note: This article has been updated to reflect Q2 2026 results for all three companies. Quanta Services’ revenue and backlog figures were refreshed to $9.56 billion and $53.4 billion respectively, Eaton’s Q2 revenue of $8.5 billion and raised full-year organic growth guidance of 11% to 13% were added, and Vertiv’s operating margin expansion of 410 basis points and its revised full-year adjusted EPS guidance of $6.65 to $6.75 were incorporated.
