3 Powerful Nuclear Energy Stocks to Buy in July
Quick Read
-
CEG trades 26% below its year-to-date start at $254 against a $360 Wall Street target, with Microsoft, Meta, and CyrusOne PPAs already locked in.
-
Cameco beat Q1 estimates by 38%, holds 230 million pounds under long-term uranium contracts, and partners with Brookfield on $80 billion in AP1000 deployments.
-
Oklo is the only SMR developer with both a site use permit and secured fuel, backed by roughly 14 GW of customer agreements anchored by Switch.

Nuclear power has shifted from a sleepy utility niche to the most strategically important corner of the energy market. AI-driven electricity demand, hyperscaler power-purchase agreements and an executive-level push to quadruple U.S. nuclear capacity to 400 GWe by 2050 have rewritten the sector’s growth math. The EIA now models commercial data-center server electricity use growing more than 16 times above 2020 levels by 2050 in its High Electricity Demand case, with baseload sources doing the heavy lifting.
Yet the sector has cooled in recent weeks, opening a window for July. Here are three nuclear-leveraged names worth a close look, each tied to a different part of the value chain: the operator, the fuel supplier, and the next-generation reactor developer.
Constellation Energy (CEG)
Constellation Energy (NASDAQ:CEG) is the largest private power producer in the United States after closing the Calpine acquisition on Jan. 7, creating a 55 GW combined fleet anchored by the country’s largest nuclear footprint. The thesis is straightforward: Hyperscalers need clean, dispatchable, 24/7 power, and Constellation already has long-term PPAs locked in with Microsoft, Meta, and CyrusOne.

The Q1 2026 numbers underline the operating leverage. Adjusted EPS landed at $2.74 versus a $2.60 consensus, a 5% beat, with revenue of $11.12 billion, up 64% year over year. Management is guiding to adjusted operating EPS of $11.00 to $12.00 in 2026 and base EPS growth of 20%+ through 2029, supported by $8.4 billion of free cash flow before growth across 2026 and 2027. The Wall Street consensus target sits at $360.24 against a current price of around $243, with the stock down nearly 34% year to date. Forward P/E of 22x is reasonable for a regulated-style cash flow profile with explicit growth.
Risk: Calpine integration execution is non-trivial. Long-term debt jumped to $17.5 billion post-Calpine, and nuclear capacity factor slipped to 92% from 94%. Any sustained operational hiccup at the fleet level would compress the multiple quickly.
Cameco (CCJ)
Cameco (NYSE:CCJ) is the cleanest pure-play on the uranium price recovery and the Western fuel cycle. The company is the world’s largest publicly traded uranium miner and owns 49% of Westinghouse, giving it exposure to both fuel and reactor services. Long-term uranium prices reached a 14-year high of $86.50/lb in December 2025, and Cameco has 230 million pounds committed under long-term contracts.
Q1 2026 EPS came in at 47 cents versus a 34-cent estimate, a 38% beat. Full-year 2026 guidance calls for revenue of $3.13 billion to $3.37 billion, uranium deliveries of 29 to 32 million pounds, and a realized price of $85 to $89 per pound. Add in a strategic partnership with Brookfield and the US Government for at least $80 billion of AP1000 reactor deployment, and the long-tail revenue picture brightens further. Shares are up 41% over the past year and 13% year to date, trading at $100.93 against a consensus target of $132.35.
Risk: Valuation is rich at a trailing P/E of 100x, and near-term operations face friction: The Key Lake mill has an extended Q3 2026 maintenance shutdown, plus a $559 million CRA tax dispute and Kazakhstan’s new Mineral Extraction Tax create overhangs.
Oklo (OKLO)
Oklo (NYSE:OKLO) is the high-beta option. The advanced small modular reactor developer is pre-revenue, with a FY 2024 net loss of $73.6 million and $275.3 million in cash and marketable securities. What it does have is a customer pipeline that few peers can match: roughly 14 GW under non-binding agreements, anchored by a 12 GW deal with Switch running to 2044, plus Equinix (500 MW with a $25 million prepayment), Prometheus Hyperscale (100 MW), and Diamondback (50 MW).
CEO Jacob DeWitte has said Oklo is “the only company with both a site use permit and secured fuel for our first deployment”, targeting first commercial Aurora deployment at Idaho National Laboratory in late 2027 to early 2028. Analyst targets average $88.63 against the current $51.32.
Risk: This is the most volatile name on the list and must be sized accordingly. Shares trade well below the 52-week high of $193.84 and well above the 52-week low of $44.88, are down nearly 18% in the past month and 38% year to date and the company has zero revenue today. Customer agreements are largely non-binding LOIs, NRC approval timing is uncertain, and additional financing may be required before first power.
What To Watch In July
The sector setup is unusually clean entering the second half. Constellation offers cash-flow-backed exposure with a hyperscaler tailwind. Cameco anchors the fuel cycle as long-term contract pricing resets higher. Oklo provides convex optionality on the SMR thesis, with the volatility to match. Keep an eye on Q2 earnings cadence, any NRC milestones for Oklo, and uranium spot moves through the Key Lake maintenance window for Cameco. Each pick maps to a different risk budget; the common denominator is that nuclear’s structural demand story is no longer in question.
