AI compute is a power problem before it is a chip problem. Hyperscaler capex keeps climbing, PJM capacity prices keep clearing higher, and utilities keep telling the same story: firm, clean, always-on megawatts are the scarce resource. Three US-listed names sit at the pointy end of that thesis, one for each layer of the nuclear stack. Constellation runs the largest US reactor fleet. Talen owns the merchant baseload assets closest to the data center demand curve in PJM. Uranium Energy supplies the fuel from domestic soil.
All three have moved on real catalysts this year, and all three are pricing in different pieces of the same trade.
Constellation Energy: Largest US Nuclear Operator, Raised Guidance
Constellation Energy (NASDAQ:CEG | CEG Price Prediction) is trading at $272.88 with a market cap near $96.7 billion and a forward P/E of 23. The Street average target sits at $347.40, with 6 Strong Buy and 14 Buy ratings against 3 Holds. Shares are down 22.41% year to date, compressing the valuation on a company that just raised guidance.
Q2 adjusted EPS of $2.55 beat the $2.3284 estimate by 9.52%, with revenue of $7.504 billion, up 23% year over year. Nuclear output hit 44,160 GWh at a 93% capacity factor. Management lifted full-year 2026 adjusted EPS guidance to $11.50 to $12.50 from $11.00 to $12.00 and reiterated a base EPS growth projection of 20% or more through 2029.
The bull case is contract-backed demand. Constellation has signed 920 MW of 15 to 20-year nuclear PPAs with investment-grade customers, is advancing the Crane Clean Energy Center restart targeting 2027, and filed license renewals for Ginna and Nine Mile Point Unit 1 out to 2049. CEO Joe Dominguez framed the quarter as "strengthening the nation’s energy infrastructure and helping meet growing demand for reliable power." Management said hyperscaler spending for 2026 was tracking "nearly 75% higher than last year and continue to be revised upward." A $5.0 billion buyback authorization with roughly $2.8 billion remaining gives management a lever if the stock stays discounted.
Risk: PJM regulatory rules for large-load interconnection and Reliability Backstop Procurement are still being written, the Illinois ZEC program ends in May 2027, and planned nuclear refueling outage days ran 86 versus 41 a year ago. Calpine integration risk is real given the scale of the January 2026 close.
Talen Energy: PJM Capacity Tailwind and Four-Gigawatt Data Center Pipeline
Talen Energy (NASDAQ:TLN) trades at $314.46, down 16.68% over the past month after a messy GAAP print. Market cap sits at $15.07 billion, forward P/E at 13, and the Street’s average target is $465.19 with 6 Strong Buy and 8 Buy ratings.
Q2 headline EPS of -$2.00 missed the $3.3912 estimate, dragged by $211 million in unrealized commodity derivative losses and interest expense that jumped to $214 million from $62 million on $4 billion in new senior unsecured notes funding Cornerstone. Adjusted EBITDA came in at $374 million versus $90 million, versus a year ago, and generation totaled 14.1 TWh. Generation nearly doubled to over 10 GW in the 2028/2029 PJM Base Residual Auction at $325/MWd.
Talen cleared more than 10 GW in the 2028/2029 PJM Base Residual Auction at $2.025 billion to $2.225 billion, raised 2026 adjusted EBITDA guidance to $40 per share, and lifted 2028 base-case free cash flow to 4 GW of land development and data center contracting options. Management flagged approximately 4 GW of data center pipeline options, with the AWS ramp expected to push long-term contracted margin from "leveraging our advantaged portfolio of assets, building our development pipeline of powered land and new capacity all of which allows us to enter into long-term contracts with large loads.". CEO Mac McFarland noted that 30% of 2028 generation is hedged.
Risk: only below 3.5x target of 2028 generation is contracted, leaving Talen exposed to a commodity reversal, and net leverage runs against a target below 3.5x as it digests Cornerstone.
Uranium Energy: Domestic Fuel, Zero Debt, Policy Tailwind
Uranium Energy (NYSE:UEC) sits at 31.14% over the past month, up 14.44% on August 21 alone and $6.26 billion. Market cap is roughly $6.26B, and the analyst consensus target implies meaningful upside. This is the upstream exposure: a pure-play US producer with the largest domestic uranium resource base.
Fiscal Q3 produced total cost per pound of $54.61 at a 200,000 pounds at $101 per pound versus a spot average of $80.76, with no revenue recognized as management held inventory. In fiscal Q2, UEC sold 1,456,000 pounds valued at $127 million. Inventory sits at $488 million in cash, backed by $794 million in liquid assets, Burke Hollow began production on April 8, 2026, and zero debt.
The catalysts are strategic. "the largest greenfield ISR uranium project to come into production in more than a decade.", described by management as "the DOE’s ‘Nuclear Dominance: 3 by 33’ initiative, which underscores the urgency of rebuilding a secure, domestic fuel supply chain." CEO Amir Adnani tied the story to Washington policy: Fluor Corporation UEC is also advancing US-based uranium refining and conversion with delayed regulatory approvals and higher Wyoming state taxes.
Risk: single-commodity exposure, no revenue this quarter, and rising per-pound costs. If uranium prices stall, the unhedged strategy cuts both ways.
Different assets, one thesis. Constellation offers scale and contract visibility, Talen offers merchant torque to PJM prices, and UEC offers the fuel. September’s setup gives investors three distinct angles on the AI power buildout to evaluate (we mapped five ways to play the nuclear restart, utilities and fuel included, in a free report here).
