3 Forgotten Small-Caps Riding the AI Power Crunch in 2026

Here's a fun party trick: ask any investor what's powering the AI buildout and they'll say $NVDA. Ask them who actually keeps those data centers from melting the power grid, and they'll stare at you like you asked them to explain options Greeks in Mandarin. Patrick Boyle's recent YouTube breakdown dropped a genuinely staggering number: the US has 65 gigawatts of data center capacity today, with another 413 gigawatts planned, equivalent to powering 330 million new homes. That electricity has to come from somewhere, and it has to be tested, managed, and cooled. That's where the interesting money is hiding.

First up: $POWL (Powell Industries). If you've never heard of this Houston-based maker of custom electrical distribution equipment, join the club. Powell builds the switchgear and motor control centers that industrial facilities and data centers literally cannot operate without. It's not glamorous. It's also not cheap to replicate. Revenue grew over 40% year-over-year in its most recent fiscal year, and backlog continues to expand as electrification demand accelerates across both the energy and tech sectors. Market cap sits comfortably under $3 billion. The bear case: margins can compress if steel costs spike, and the company is small enough that one bad quarter rattles the stock hard. The catalyst to watch is whether hyperscaler capex announcements, which Bloomberg Intelligence flagged with a combined cloud backlog exceeding $1.5 trillion, start flowing down to infrastructure suppliers like Powell in procurement announcements.

Second on the list: $AMPS (Altus Power). This is a commercial-scale clean power producer that deploys solar directly on rooftops and carports for corporate clients, essentially becoming the on-site utility for businesses that need cheap, stable electricity. With power costs becoming a genuine existential issue for anyone running GPUs at scale, locking in below-market electricity via a 20-year PPA is suddenly a very compelling pitch. Market cap is under $2 billion. The bear case here is real: rising interest rates in 2025 crushed clean energy valuations, and the 10-year yield bouncing around 5% this week doesn't help levered infrastructure plays. But if rates are peaking, this one re-rates fast.

Third and arguably the most under-the-radar: $CVCO (Cavco Industries). Stay with me here. Cavco builds factory-built homes, which sounds about as exciting as watching paint dry, but housing affordability is a genuine crisis and factory construction is 30 to 50% cheaper than site-built homes. The kicker: AI campus buildouts are creating boomtowns in mid-American cities that desperately need fast, affordable housing for the workers building and operating those facilities. Cavco's vertically integrated model and lean manufacturing give it real pricing power in exactly those markets. Market cap: around $3 billion. Bears will note it's cyclical and sensitive to mortgage rates, but the structural housing deficit isn't going away anytime soon.

Three completely different businesses, one connecting thread: everyone's looking up at the clouds while the real opportunity is quietly humming away in the infrastructure underneath them.
