AI's Power Bottleneck: 5 Stocks Behind the Buildout

Vertiv (VRT) raised full-year 2026 guidance to $6.30–$6.40 per share yesterday from $5.97–$6.07, watched its shares fall more than 5% premarket, and still closed down 2.3% at $305.14. A beat-and-raise that triggered selling in a stock up 94% year-to-date tells us something specific: the AI power trade is no longer about surprise. It is about selectivity.

BlackRock estimates US data centres will need 148 GW of additional power capacity by 2030, against 42 GW consumed in 2025. US data centre construction starts hit $36.9bn in the first two months of 2026, up from $1.4bn a year earlier. Demand is unarguable.

Why Vertiv Sold Off on a Beat-and-Raise

Q1 was clean: net sales +30%, adjusted operating profit +64%, and inaugural investment-grade ratings from Moody's (Baa3) and S&P (BBB-). Selling came from three places. Vertiv no longer publishes quarterly orders, removing the momentum metric that drove last quarter's 252% print. Q2 organic sales growth guidance of 20%–24% reads as deceleration from Q1's 30%. And the stock entered the print up 94% year-to-date.

The broader Power stack shows where the selectivity is going. The 24-stock AIIP Power stack returned 4.7% over the past week, beating the AIIP universe (+4.6%). The bounce was strikingly uneven: POWI jumped 30.7%, GEV 14.4%, HUT 13.6%, while Vertiv itself managed just 1.3%. Money is rotating within the stack, not out of it. Ordered by Combined Score, here are the five names to have on the radar this week.

Vertiv Holdings $VRT ( ▼ 2.34% )

Sector / Industry: Industrials | Electrical Equipment & Parts
AI Stack Layer: Power (Data Centre Thermal & Power Infrastructure)
Market Cap: $120bn
1 Week: +1.3% | YTD: +88.4%
Combined Score: 175.4/200
AIIP Ranking: Watchlist

The AI Thesis Vertiv sells the physical layer of AI: liquid cooling, power distribution, and prefabricated modular data centre solutions. As rack densities climb past 250kW for Blackwell and Vera Rubin class systems, air cooling reaches its limits and Vertiv's liquid-cooling book becomes structural rather than optional.

Current Picture Q1 2026 delivered a beat-and-raise across every line item, yet shares fell over 5% premarket before buyers stepped in to cut the loss in half, closing at $305.14, down 2.3% on the day. Combined Score of 175.4 keeps Vertiv alone in Watchlist territory within the Power stack. The intraday recovery shows dip-buyers engaging at Watchlist-quality names, though a red close on a strong print illustrates how entry timing can influence outcomes when multiples are already elevated.

Bloom Energy Corporation $BE ( ▲ 4.0% )

Sector / Industry: Industrials | Specialty Industrial Machinery
AI Stack Layer: Power (On-Site Generation / Bring Your Own Power)
Market Cap: $62bn
1 Week: +7.4% | YTD: +164.4%
Combined Score: 162.3/200
AIIP Ranking: Momentum

The AI Thesis Bloom sells natural-gas fuel cells that generate electricity on-site without the grid. Hyperscalers are increasingly bypassing overstretched utilities and underwriting their own power directly, which is the BYOP (Bring Your Own Power) model BlackRock references. Oracle has expanded its Bloom contract; Brookfield is a named infrastructure partner.

Current Picture Up 164% year-to-date and over 1,260% on the trailing year. Combined Score of 162.3 reflects strong revenue growth and relative strength, offset by weaker financial quality. Bloom is the most pure-play on-site AI power generation exposure in the Power stack, with the most extended valuation profile of the five names covered here.

Hut 8 Corp. $HUT ( ▲ 5.43% )

Sector / Industry: Technology | Data Centres & Mining
AI Stack Layer: Power (Mining-to-AI Hosting Conversion)
Market Cap: $8.5bn
1 Week: +13.6% | YTD: +75.8%
Combined Score: 139.6/200
AIIP Ranking: Momentum

The AI Thesis Hut 8 is a Bitcoin miner in name and an AI infrastructure host in economic reality. Its grid connections, cooling systems, and power purchase agreements, built for mining, are precisely what hyperscalers need and cannot replicate quickly. Converting mining megawatts to AI hosting revenue generates materially higher margins.

Current Picture Up 585% over the trailing year as the market re-prices the miner-to-hoster pivot. Combined Score of 139.6 reflects middling growth and financial quality but strong relative strength as new AI hosting contracts ratify the thesis. Most differentiated of the five picks and least covered by generalist AI newsletters.

GE Vernova Inc. $GEV ( ▲ 13.75% )

Sector / Industry: Industrials | Specialty Industrial Machinery
AI Stack Layer: Power (Grid Equipment & Gas Turbines)
Market Cap: $267bn
1 Week: +14.4% | YTD: +72.8%
Combined Score: 132.5/200
AIIP Ranking: Momentum

The AI Thesis GEV makes the heavy equipment that keeps the grid standing: gas turbines, wind turbines, high-voltage transmission, and grid-scale batteries. BlackRock's 148 GW estimate routes directly through GEV's order book, and gas turbine manufacturing capacity is scaling because BYOP customers and utilities are both buying.

Current Picture Up 73% year-to-date with a Combined Score of 132.5 and a relative strength reading of 88.7. Within the Power stack, GEV combines a steadier price path with less extended valuation than several other names, offering a different risk profile to consider alongside higher-momentum alternatives.

Power Integrations, Inc. $POWI ( ▲ 6.47% )

Sector / Industry: Technology | Semiconductors (power conversion)
AI Stack Layer: Power, Build (Power Management Semiconductors)
Market Cap: $3.8bn
1 Week: +30.7% | YTD: +102.7%
Combined Score: 132.1/200
AIIP Ranking: Momentum

The AI Thesis POWI designs high-voltage analogue ICs that convert, regulate, and protect power in servers, data centre equipment, and industrial systems. As AI server power draws climb, the density and efficiency of on-board power conversion become a competitive constraint. Smaller than Monolithic Power, more concentrated AI exposure.

Current Picture Combined Score of 132.1 is the lowest of the five, but the valuation score of 100 is notable: POWI is the only stock in this group where AIIP's model shows valuation not working against the thesis. This past week's +30.7% was the strongest single-week move in the Power stack.

Final Take

The AI power trade is not over. BlackRock's 148 GW, the 25x jump in construction starts, and Vertiv's guidance raise all confirm the capex cycle is still accelerating. What has changed is the margin of safety: this week's dispersion, with VRT flat while POWI ripped 30%, shows the easy phase is behind us.

Next up for the trade: hyperscaler Q1 earnings. Microsoft, Alphabet, Meta, and Amazon all report over the next two weeks. Their AI capex numbers and data centre commentary will either confirm the buildout thesis through another round of raised spending, or put the first real pressure on the Power complex. That is where this week's dispersion either widens or reverses.
