For most of 2024-2025, the AI infrastructure conversation revolved around chips. In 2026, the conversation has shifted: the binding constraint is now electricity. Hyperscalers can buy more GPUs, but they cannot conjure 1-2 GW of firm, 24/7 power into a substation overnight. Transformer lead times have stretched past 100 weeks, utility interconnect queues are years long, and gas turbine slot reservations are sold out into the next decade.
That power scramble has rewired the market. Equity capital is flowing into a new set of names: gas turbine OEMs, fuel cell makers, and a re-energized small modular reactor (SMR) cohort. This piece focuses on the two largest beneficiaries — GE Vernova (GEV) and Bloom Energy (BE) — plus the SMR provider landscape that is increasingly being designed into hyperscaler campuses for the late-2020s / early-2030s.

💡 Pro Tip: AI power names trade on a fundamentally different clock than chip names. Orders and backlog don’t translate to revenue for 2-5 years. The right metric to track is backlog growth and slot-reservation conversion, not next-quarter EPS.
⚡ Why Power, Not Compute, Is Now the Bottleneck
The numbers are stark. US data center electricity demand has jumped from roughly 50 GW in 2024 to a projected 76 GW in 2026, and global AI-driven consumption is on track to add ~90 TWh of annual load this year alone. Total data center load is approaching 1,050 TWh — which would make data centers the fifth-largest “national” electricity consumer in the world. Meanwhile, US grid additions, transformer manufacturing, and gas turbine production cannot expand on the same curve.
That mismatch is forcing three structural responses: (1) behind-the-meter gas generation co-located with data centers, (2) fuel cells as a fast-deploy, permittable alternative to grid waiting lists, and (3) nuclear restarts and SMRs as the long-duration, carbon-free baseload that hyperscalers’ climate commitments require. The three companies / cohorts below capture all three vectors.

110 GW gas backlog
Grid electrification
BWRX-300 SMR
The theme: GEV is the most direct, fully diversified play on AI power. Its three segments — Power (gas, hydro, steam, nuclear), Wind, and Electrification (grid + storage) — line up against every layer of the data center power stack, from on-site turbines to substations to long-duration baseload.
- Q1 2026 orders $18.3B, +71% organic; total backlog approaching $200B
- Targeting 110 GW of combined gas turbine backlog + slot reservations by year-end 2026
- Electrification segment booked $2.4B in data-center equipment orders in Q1 alone — more than all of 2025
- Joint venture GE Vernova Hitachi Nuclear Energy commercializing the BWRX-300 SMR — first projects targeted for 2029 deliveries (Texas, Ontario, Tennessee)
- Pioneered the “gas-plus-nuclear” campus model — 2.5 GW Texas project pairs 7HA.02 gas turbines with BWRX-300 reactors as a transitional AI-power architecture
👀 What to watch: Quarterly slot-reservation conversion into firm orders, Electrification margin expansion (the data-center order surge should compound here), and BWRX-300 milestone licensing news from the NRC and CNSC.

🔥 Bloom Energy (NYSE: BE) — Fast Deploy, Behind-the-Meter Power
|
Solid-Oxide Fuel Cells · On-Site Generation
Bloom Energy (NYSE: BE)
|
Mkt Cap ~$80B
|
SOFC
+301% YoY
~4 GW signed
The theme: Bloom’s solid-oxide fuel cells run on natural gas (or hydrogen blend), deploy in months not years, and bypass the interconnect queue entirely. That has turned BE from a niche distributed-generation player into the de-facto fast-deploy power source for AI-driven greenfield builds.
- $2.65B AEP deal (Jan 2026) — up to 1 GW of fuel cells deployed across American Electric Power’s footprint
- Oracle agreement up to 2.8 GW announced Q2 2026, with initial deployments within 3 months of signing
- $5B Brookfield strategic partnership — Brookfield funds global SOFC deployment at AI data centers; Bloom builds and operates
- Equinix expansion — fuel cells now deployed at 19 colocation sites, >100 MW total
- Scaling manufacturing capacity from 1 GW → 2 GW per year by end-2026 (~$100M capex)
- Stock has rallied +301% YoY through May 2026 as commercial validation has compounded
👀 What to watch: Conversion of the AEP, Oracle and Brookfield framework deals into shipped product, gross margin trajectory (a major bull-thesis swing factor), and any incremental hyperscaler PPA-equivalent wins.

☢️ The SMR Renaissance — Who’s Actually Building What
Small Modular Reactors are the most credible answer to hyperscalers’ need for firm, 24/7, low-carbon power. After two decades of false starts, the cohort is finally maturing — driven by Department of Energy funding, hyperscaler offtake commitments, and an updated NRC licensing framework. As of May 2026, every major US hyperscaler has signed at least one nuclear-related deal for AI capacity. Here are the listed players doing the building.

Fast-Spectrum SFR · Sam Altman-Chaired
Oklo Inc. (NYSE: OKLO)
|
Mkt Cap ~$11.6B
|
|
Aurora 15-75 MW
INL site
Data-center LOIs
The theme: Oklo’s Aurora “powerhouse” is a sodium-cooled fast reactor (SFR) designed to operate without on-site refueling for ~10 years. The company is targeting a Build-Own-Operate model — selling electricity, not reactors — which lowers customer adoption friction. A long pipeline of data-center developer LOIs is the main valuation driver.
👀 What to watch: Combined License Application progress at the NRC, the first commercial Aurora at the Idaho National Lab site (targeting 2027-2028), and conversion of LOIs to firm PPAs.

Xe-100 80 MW
Amazon offtake
Dow Texas site
The theme: Just IPO’d on April 24, 2026 (priced at $23, above the $16-19 range, raising $1.02B), X-Energy is the SMR designed-in to the highest-profile hyperscaler deal — Amazon’s Xe-100 offtake for AWS data centers. Its TRISO-fueled, gas-cooled architecture offers higher operating temperatures, useful for both electricity and industrial heat (e.g., Dow’s Seadrift, TX chemical plant).
👀 What to watch: Progress on the Dow Seadrift demonstration unit, Amazon offtake site selection, and lock-up expiry dynamics post-IPO.

Reactor vessels
HALEU
BWXT Advanced
The theme: The picks-and-shovels of the SMR cycle. BWXT manufactures the precision-forged reactor components and pressure vessels that every Western SMR design requires — irrespective of which design wins the commercial race. The company also runs the US naval reactor program (steady cash-flow base) and is investing in HALEU fuel and microreactor units.
👀 What to watch: Q1 2026 print already in (~$860M revenue) — focus on Commercial Operations segment growth, HALEU contract wins, and SMR component order book.

Light-Water SMR · VOYGR · TVA Anchor
NuScale Power (NYSE: SMR)
|
$1B liquidity (Q1’26)
|
|
77 MW modules
TVA 6 GW pipeline
NRC-certified
The theme: NuScale’s 77 MW VOYGR module is the only SMR with NRC design certification in hand — a meaningful regulatory moat. Its exclusive partner ENTRA1 is working with Tennessee Valley Authority on a planning program for up to 6 GW of NuScale capacity — what would be the largest US nuclear deployment in history.
👀 What to watch: First firm order conversion (UAMPS replacement project), TVA deployment cadence, and supply-chain build-out at module fabrication partners.

🔎 Also on the radar
Centrus Energy (LEU) — the only US-licensed producer of HALEU (high-assay low-enriched uranium), the fuel required by nearly every advanced SMR design. A pure picks-and-shovels play, less binary than reactor developers.
NANO Nuclear Energy (NNE) — earlier-stage, more speculative microreactor developer (ZEUS, ODIN designs) targeting remote/edge AI inference sites and defense applications. High beta, story-stock dynamics.
Constellation Energy (CEG) & Vistra (VST) — not SMR developers, but the most direct existing-fleet beneficiaries via the Microsoft Three Mile Island restart ($16B / 20-yr PPA, 835 MW expected 2027) and Meta nuclear offtake deals.
📈 Key Insight: The AI power trade has three distinct time horizons: (1) 2026-2028 belongs to gas turbines and fuel cells (GEV, BE) — the only deployable firm power at scale; (2) 2027-2030 belongs to existing nuclear restarts (CEG, VST) and the first commercial SMRs (OKLO, XE, SMR); (3) post-2030 belongs to mass-produced SMR fleets where BWXT-class component suppliers compound. Different horizons mean different stocks — a basket of all three captures the full curve.
⚠️ Watch Out: SMR developers have repeatedly missed cost and schedule targets — NuScale’s 2023 UAMPS cancellation is the cautionary tale. Major risks: (1) regulatory delays at the NRC, (2) FOAK (first-of-a-kind) cost overruns, (3) hyperscaler offtake retraction if AI capex slows, and (4) natural gas substitution — every quarter SMRs slip, GEV’s gas turbine slot reservations get more valuable.

📊 Portfolio Takeaway
If you already own the AI mega-caps, the cleanest way to add “power” exposure is a barbell: GE Vernova as the diversified core (gas + grid + nuclear in one wrapper) plus a smaller satellite in Bloom Energy for the near-term fast-deploy angle. Treat the SMR cohort (OKLO, XE, SMR, NNE) as venture-style optionality — high variance, multi-year payoff, ~1-2% portfolio weight each. BWXT and LEU are the lower-volatility picks-and-shovels if you want SMR exposure without picking the design winner.
