Market Backdrop
In a market fixated on AI chips, investors are increasingly turning to the durable, real-world infrastructure that powers the data centers behind the AI boom. As of May 2026, a steady drumbeat of results from Caterpillar, Eaton, and Vertiv is drawing attention away from the hype around hyperscalers and toward long-cycle players that actually build and run the AI backbone.
The pullback in the hype focused on chipmakers has coincided with a broader realization: the AI machine needs reliable power, cooling, and physical infrastructure just as much as it needs silicon. Investors are starting to price in the resilience of these industrial plays as data-center capex remains robust through the current cycle.
Analysts and portfolio managers are rallying around a simple refrain in discussions about AI investing: forget hyperscalers, these stocks are the real AI plays that could compound earnings for years. The consensus is that the big hardware builders offer a steadier path to growth as AI deployments scale across industries, from manufacturing floors to financial data rooms.
Caterpillar: The Power Behind AI Rigs
- Q1 2026 power generation revenue rose 41% year over year to about $2.82 billion.
- Total company revenue climbed roughly 22% to about $17.41 billion for the quarter.
- Earnings per share surpassed consensus by about 19% in the period, underscoring margin leverage from higher industrial equipment demand.
Caterpillar’s quarterly mix shows how AI-related data-center activity is crossing into the broader machinery economy. The company noted stronger orders for power-generation equipment that supports on-site data-center operations, backup power, and sustainable energy deployments. With capex cycles extended and customers prioritizing uptime, CAT is benefiting from a multi-quarter runway in mission-critical equipment. The stock has drawn attention for a growth story rooted in infrastructure spending rather than flashy chip names.
Analysts watching the sector say Caterpillar’s exposure to high-utility systems—generators, turbines, and power controls—puts it in a solid position as data centers scale and need reliable, long-life hardware. One market watcher noted that AI infrastructure depends on physical backbone, not just software stacks.
Eaton: Cooling Upgrades Fuel Data Center Demand
- Electrical Americas revenue hit a record of about $3.51 billion in Q1 2026, up roughly 21% year over year.
- Reported a 24.9% segment margin, signaling strong profitability in the electrical distribution and cooling segments.
- Acquired Boyd Thermal for about $9.5 billion to expand data-center cooling capabilities and broaden thermal-management offerings.
Eaton’s latest results emphasize the role of advanced cooling and electrical infrastructure in AI deployments. The Boyd Thermal acquisition expands the firm’s footprint in data-center environments, aligning with hyperscale and edge deployments alike. The company also highlighted resilience in its electrical and logistics segments, which investors see as a hedge against more cyclical industrial demand.
Industry experts say the data-center cooling market is a critical bottleneck in AI scaling, and Eaton’s expanded capabilities position it to win share as capacity tightens and buildouts accelerate. In investor conversations, the focus is on long-cycle contracts and service revenue, which should support margin stability in a volatile macro backdrop.
Vertiv: The Silent Backplane of AI Growth
- Q1 2026 revenue rose about 30% year over year to roughly $2.65 billion.
- Backlog stood at around $15.0 billion, up about 109% from a year earlier, signaling strong demand visibility.
- Book-to-bill near 2.9x and 2026 revenue guidance raised to $13.50-$14.00 billion, with adjusted earnings per share in a range of $6.30-$6.40.
Vertiv’s results underscore a pivot from pure hardware to ongoing lifecycle services and integration. The backlog expansion points to an elevated sustained demand for the physical infrastructure that supports AI workloads, from power distribution to cooling systems for data centers of all sizes. With a book-to-bill well above 2x, Vertiv is signaling that the current demand cycle could outlive the near-term hype around AI chips.
Investors familiar with Vertiv emphasize the importance of the company’s services and retrofit opportunities in sustaining growth as customers optimize green energy and data-center efficiency. As AI adoption broadens, Vertiv’s role as a provider of end-to-end mission-critical infrastructure makes it a compelling bet for a diversified AI exposure strategy.
What This Means for Investors
The AI market remains characterized by a mix of marquee chip names and the much larger, less glamorous hardware ecosystem that keeps those chips running. In this cycle, the data-center backbone appears to be gaining more attention as a reliable, long-duration growth lever. The trio of Caterpillar, Eaton, and Vertiv demonstrates how the AI buildout extends beyond software and into the real-world machinery that powers data centers, factories, and critical infrastructure.
For investors who want to avoid the crowded hyperscaler trade, these stocks offer several attractions: visible backlog growth, durable cash flow, and exposure to longer cycle spend that tends to weather macro volatility. The market narrative around AI infrastructure is slowly shifting to a more balanced view that credits the hardware layer as a strategic, repeatable growth engine rather than a single trend.
Analysts across mid-cap and industrials desks are revisiting the AI investment thesis with a focus on backbone suppliers rather than headline chip names. Some observers caution that the sector remains sensitive to interest rates and supply-chain dynamics, but the current results provide a proof point that AI expansion is broad-based and ongoing.
As one veteran analyst put it, the AI machine is not just about the speed of silicon; it’s about the reliability of the platform that keeps chips powered, cooled, and connected. That reality lends credibility to the strategy of ‘forget hyperscalers, these stocks’ as a practical lens for what to own in 2026 and beyond.
Risks to Consider
- Interest-rate exposure and the cost of debt could weigh on capex-driven names.
- Global supply chains and component shortages may delay some projects.
- Execution risks in large-scale acquisitions and integration of cooling technologies.
Investors weighing these choices should balance the potential for long-cycle growth with near-term macro headwinds. The message from CAT, ETN, and VRT is clear: AI progress is a marathon, not a sprint, and the infrastructure layer is where durable value can accumulate.
Bottom Line
In an era where AI hype often centers on chips, the real-money story may lie in the companies building and maintaining the AI backbone. Caterpillar, Eaton, and Vertiv illustrate how AI-driven demand translates into measurable gains in revenue, margins, and backlog. For investors aiming to diversify away from crowded hyperscaler bets, these stocks offer a compelling blend of growth, resilience, and playbook longevity. In short: forget hyperscalers, these stocks remain among the most credible AI plays for the long haul.
