Forget Hyperscalers, These Stocks Are The New AI Plays

The leading AI chip names are dominating every AI headline, and for good reason: their chips and platforms sit at the center of the buildout.

But here’s what you should actually be watching.

The crowded chip trade already prices in every bullish scenario investors can dream up. Retail money piles in on every dip, options chains stay lit, and the consensus is so dense that any disappointment carries asymmetric downside. Meanwhile, the unglamorous companies physically building the AI economy keep posting record numbers with almost no retail noise. That is what an uncrowded trade looks like, and it is exactly where a retirement-focused investor wants to be hunting.

Caterpillar: the power plant behind the GPU

Caterpillar (NYSE:CAT | CAT Price Prediction) does not show up in AI ETFs, yet its Power Generation product line grew 41% YoY to $2.817 billion in Q1 2026, driven by large reciprocating engines and turbines feeding hyperscale data centers. Total revenue hit $17.415 billion (up 22.22% YoY), reported EPS landed at $5.54 versus a $4.6439 consensus (a 19.3% beat), and net income climbed 27.26% YoY to $2.549 billion. Management deployed $5.028 billion in buybacks plus roughly $0.7 billion in dividends in the single quarter. CEO Joe Creed pointed to a record backlog providing “a strong foundation for continued positive momentum”. Shares are up 57.33% YTD and 179.78% over the past year, and retail still cannot be bothered.

Eaton: electrifying the rack

Eaton (NYSE:ETN) runs the electrical distribution that turns Caterpillar’s power into usable kilowatts inside the hall. Q4 2025 Electrical Americas revenue hit a record $3.51 billion (up 21% YoY, 15% organic) at a record 24.9% segment margin, with electrical backlog up 29% YoY and a book-to-bill of 1.1. The company is acquiring Boyd Thermal for $9.5 billion to bolt liquid cooling onto the data center stack, with the deal expected to close in Q2 2026. 2026 guidance calls for 7% to 9% organic growth and adjusted EPS of $13.00 to $13.50. CEO Paulo Ruiz framed it directly: the company is “confident that this momentum positions us to capitalize on the significant opportunities ahead, from digitalization and AI to reindustrialization, infrastructure spending and growth in the aerospace markets.” Shares are up 26.79% YTD.

Vertiv: the pure-play nobody is panicking over

Vertiv (NYSE:VRT) is the cleanest read on data center critical infrastructure: power, cooling, racks. Q1 2026 revenue jumped 30.13% YoY to $2.6495 billion, adjusted EPS of $1.17 came in well ahead of the $1.011 consensus, and Americas revenue surged 53.1% YoY to $1.8144 billion. Adjusted operating margin expanded 430 basis points to 20.8%, and operating cash flow ripped 152.82% higher to $766.8 million. Q4 2025 backlog reached $15.0 billion (up 109% YoY) with a book-to-bill near 2.9x. Management raised 2026 guidance to $13.50 billion to $14.00 billion in net sales and $6.30 to $6.40 in adjusted EPS, roughly 50% to 52% earnings growth at the midpoint. Joined the S&P 500 in March 2026 and earned inaugural investment-grade ratings from Moody’s (Baa3) and S&P (BBB-) in February 2026. Up 109.89% YTD with consistently low retail chatter.

The action

For investors looking past the crowded chip trade, the picks-and-shovels operators powering the AI capex cycle, Caterpillar, Eaton, and Vertiv, are worth a closer look as the institutional bid continues to build.
