The Best 3 Nuclear Energy Stocks to Buy and Hold for 2030 and Beyond

Electricity is something many of us take for granted. Flip a switch, plug a charger, nuke some leftovers, and pop ... there it is. But energy, by the looks of it today, could be in short supply soon. It might not leave your home in the dark, but an immense strain on the grid could slow the development of artificial intelligence (AI), whose sprawling data centers need enormous amounts of electricity to run.

No one company or industry is going to solve AI's power needs. At the same time, nuclear energy is widely seen as a part of the solution: Reactors can generate enormous amounts of electricity around the clock without dependence on the sun or wind. And for investors looking toward 2030 and beyond, these three nuclear energy stocks are worth considering.

1. Constellation Energy

Constellation Energy (NASDAQ: CEG) owns the largest nuclear fleet in the U.S., with over 44,160 gigawatt-hours of electricity produced by its nuclear fleet in the second quarter. That's almost enough to power 16 million U.S. homes for three months.

Constellation's massive nuclear fleet is one reason to own the stock. But it's not the main reason I'd hold it through 2030 and beyond.

The bigger draw, to me, is that it can turn this fleet and today's immense demand for power into binding agreements that can last decades.

Take, for example, Microsoft and Meta Platforms. Both tech companies have signed 20-year power purchase agreements with Constellation. These commitments last well beyond 2030 and could easily serve as a model for other tech companies looking to secure their own power supply needs.

One drawback is valuation. At about $285 a share, Constellation trades for roughly 24 times the midpoint of its 2026 adjusted earnings guidance. Still, for a highly profitable energy stock with an already existing nuclear fleet, Constellation is a solid pick for modest growth.

2. Uranium Energy

If there's one thing that could ground nuclear energy to a halt, it's a shortage of fuel. Reactors need uranium, and expanding its supply will require mines, processing facilities, and equipment to turn uranium into reactor fuel.

You can probably guess where this is going: Uranium Energy (NYSEMKT: UEC) is positioning itself to supply more of that fuel. Indeed, it already has facilities in North and South America and is currently expanding its uranium production in Wyoming and Texas.

Uranium Energy doesn't, to be sure, have an enormous stockpile of uranium. It's roughly 1.73 million pounds, including materials still being processed, which is less than 4% of the roughly 47 million pounds delivered to U.S. nuclear reactor operators in 2025.

That's small in comparison, but there's a bright spot in the data: Only 7% of uranium delivered to U.S. nuclear power plants in 2025 was of U.S. origin. If utilities want to buy reactor fuel more domestically, Uranium Energy could be well-positioned to benefit.

3. Oklo

Oklo (NYSE: OKLO) is a bit of an outlier on this list. It isn't an established business -- it isn't, that is, generating significant revenue -- and it requires more imagination, plus a stronger appetite for risk. But the upside could be immense if its vision comes into reality.

That vision, in a nutshell, is this: a small nuclear reactor ("Aurora powerhouses" which are about the size of a house) can be built near data centers, factories, communities, and wherever else power is needed. Oklo wants to own these small reactors and sell the electricity from them -- kind of like how a utility company sells power today. The "power as a service" model would generate recurring revenue and hold Oklo responsible for the reactor's upkeep, which might make it easier for businesses to adopt this novel form of nuclear energy.

If Oklo can pull it off, there's immense growth ahead for this nuclear start-up. Right now, the biggest hurdle is regulatory. Oklo has yet to get the Nuclear Regulatory Commission's blessing, and it hasn't established a firm timeline for when it can operate Aurora commercially.

The wait for regulatory approval hasn't, however, stopped Oklo from inking preliminary deals. At the end of 2025, Oklo said it had a backlog equal to 14 gigawatts (GW), and in January 2026, it announced a landmark agreement to support Meta's data centers through a nuclear campus in southern Ohio. This plant is expected to come online in the 2030s, though, again, Oklo needs its regulatory ducks in a row before it can.

These three nuclear stocks offer different ways to plug into nuclear's future. If you don't want to handpick individual winners, however, a nuclear-focused exchange-traded fund (ETF) could give you a basket of nuclear stocks in one purchase, offering broader exposure to this growing industry.
