Best nuclear energy stocks
Nuclear returned to the conversation because data centres need firm, carbon-free power on a 24-hour basis, which renewables alone cannot contract for.
The screen: 9 US exchange-listed companies across 2 sectors (Utilities, Energy), 4 of which pay a dividend. Size mix: 2 large-cap, 2 mid-cap, 4 small-cap, 1 micro-cap.
What separates the winners from the losers here
- Existing fleet versus promised new build — timelines differ by a decade
- Power purchase agreements signed with data-centre operators
- Fuel supply and enrichment exposure

Where to buy them
To hold these as real shares you need a stockbroker rather than a CFD provider. If you only want exposure to the price movement, a share CFD does that with leverage — and without ownership.

Frequently asked questions
How many nuclear energy stocks are in this list?
9, drawn from our US exchange-listed universe and spread across 2 sectors. 4 of them pay a dividend.
Is this a list of nuclear energy stocks to buy?
No. It is a screen — a defined, reproducible filter over a stated universe. A screen tells you which companies share a characteristic; it says nothing about whether the price you would pay today is a sensible one. Nothing here is investment advice.
What is the main risk with nuclear energy stocks?
New build has a long, well-documented history of delay and cost overrun; small modular reactor revenue is still largely prospective.
How do I actually buy these from outside the US?
You need a broker that accepts your country of residence and gives you access to US exchanges. To own the shares outright, that usually means an international stockbroker plus a W-8BEN form to claim your treaty rate on dividend withholding.
