From 2026 to 2030, the capacity of AI data centers newly built each year and completed using modular construction is expected to grow 24% annually, with penetration rising from 40% to 57%. Wall Street is rushing to buy these 18 modular-construction masters:
Integrated Equipment Providers
1. Vertiv
$VRT The only all-around player that simultaneously offers busway power distribution, liquid-cooling CDUs, and modular data centers. Its OneCore architecture can support 1GW-scale campuses. Modular construction cuts on-site work from 70 weeks to 10 weeks, and Vertiv’s data is the strongest among the three. With a target price of $368, it has nearly 50% upside from the current price of $250, making it the purest high-beta play in this thesis.
2. Eaton
$ETN The North American leader in electrical equipment, manufacturing its own UPS systems, switchgear, and busway across the board. After modularization, it can self-supply 80%-90% of the module content, making it difficult for single-product suppliers to challenge its integration position. Data center-related orders continue to grow rapidly. With a target price of $534, this century-old company is benefiting from AI’s new wave while offering both stability and exposure.
3. Schneider Electric (listed in Europe
The most experienced in project delivery among the three. It has personally validated a case in which the modular deployment cycle was reduced from 88 weeks to 34 weeks. Its target price is 350 euros. There is no direct ticker in the U.S. stock listings, so those seeking exposure can consider its Paris/London-listed shares or OTC channels.
Grid Equipment
4. GE Vernova
$GEV The U.S. one-stop contractor for “power generation + the grid.” Its gas turbine order book extends several years into the future, while transformers and switchgear are unavoidable bottlenecks for data center grid connections. On-site power generation is helping alleviate electricity shortages, and GEV manufactures both gas turbines and grid-connection equipment, giving it exposure on both sides. It is one of the scarcest one-stop plays in the power-shortage narrative.
5. Forgent Power Solutions
$FPS A newly listed electrical equipment provider that went public only in July 2025. Its core business is power distribution equipment for data centers, the grid, and energy-intensive factories. It is small in scale and highly focused, with a valuation in the tens of billions of dollars. It is the stock on this list that most resembles a pure modular-construction lottery ticket—highly volatile, but positioned in the right sector. It just released its annual report and is suitable for tracking with a small position.
6. Hubbell
$HUBB The unsung champion of the grid: transformer components, distribution hardware, and utility electrical products—everything that is needed wherever electricity flows. It is not glamorous but extremely stable. It gets a share of every dollar of capital spending on grid expansion, making it the portfolio’s anchor.
Busway and Liquid Cooling
7. nVent Electric $NVT
A dual-exposure player in busway and liquid-cooling piping. Its data center revenue is rising rapidly. With a small scale and fast-moving operations, it is the most direct second-tier beneficiary, and its valuation is much cheaper than VRT’s.
Cooling and CDUs
8. Modine Manufacturing $MOD
A textbook example of a company transforming from automotive radiators to data center liquid cooling. It offers cold plates, rack-mounted CDUs, and immersion-cooling solutions, and is a behind-the-scenes supplier of liquid cooling for NVIDIA’s next-generation racks. With a small market cap and high growth, it offers the greatest upside in the cooling group.
9. Trane Technologies $TT
A commercial HVAC giant. Chiller systems are standard equipment for large data centers, and its order backlog continues to hit new highs. Its advantage is that even if AI construction slows, building and infrastructure demand can provide a cushion. It is a cooling position where “even if you’re wrong, you won’t get wiped out.”
10. Johnson Controls $JCI
An end-to-end provider of cooling equipment, control systems, and building automation, with data center cooling orders growing rapidly. Like Trane, it is a relatively stable play, but it also benefits from digital operations and maintenance. It suits investors seeking cooling exposure with lower volatility.
Battery Energy Storage
11. Eos Energy $EOSE
Zinc-based long-duration energy storage. Its U.S.-based supply chain is its moat, while its pipeline of data center backup-power and peak-shaving orders continues to expand. With a market cap of only approximately $1.2 billion, it is a small and focused name in the energy storage group, offering high risk and high upside.
12. Tesla $TSLA
Don’t look only at the cars. Its Megapack energy storage business is an important hedge against the auto cycle, and large data center on-site power orders continue to come in. Although it is not a pure-play name, its brand, production capacity, and delivery capabilities are irreplaceable.
13. Fluence Energy $FLNC
An energy storage system integrator backed by two major shareholders, Siemens and AES, with extensive experience in grid-scale energy storage projects. Its stock price has been painful in the past, but orders have improved noticeably at the margin as demand for data center storage has emerged. It is a potential turnaround candidate.
Electrified Sites
14. IREN $IREN
A computing company that transformed from an Australian-based operation, with ample owned grid-connected capacity and large GPU orders already secured. Its transition from mining to AI cloud services is progressing faster than that of its peers. The longer new projects remain in the queue, the more valuable its ready-to-use MW capacity becomes.
15. Cipher Mining $CIFR
It has high-quality power resources in Texas and has signed long-term AI hosting agreements with multiple hyperscale cloud providers. With a market cap of less than $8 billion, the pace at which its leases are realized will determine its valuation ceiling. It is one of the few small-cap names with backing from major customers.
16. Core Scientific $CORZ
Transitioning from Bitcoin mining to HPC hosting, it has signed multiyear agreements with companies such as CoreWeave. Contracts worth approximately $1.2 billion provide tangible support for its cash flow. Its transition certainty ranks among the highest in the mining-stock group.
17. Applied Digital $APLD
The owner of prime real estate in North Dakota, featuring extremely cold weather and cheap power. It is developing new campuses specifically designed for AI and advancing cooperation with hyperscale customers. It is the purest “new AI campus” story on the list, with substantial room for imagination.
18. TeraWulf $WULF
A benchmark for converting mining sites to zero-carbon power, with deep equity-level ties to technology giants such as Google. Its AI hosting projects are steadily ramping up. Investment from major companies amounts to an indirect endorsement, making it the most strongly backed name in the mining-to-AI group.
