Back in one of the very first posts on this blog, published in January 2025, I wrote about what I believed would be the real investment trend of the next 10 years, a trend that, at the time, no one was really talking about: nuclear energy.
I won’t go into all the reasons why I think nuclear is one of the most promising long-term sectors, if you’re interested in the full breakdown, you can read my original analysis here, but today I want to focus on what has happened in recent months and explain why there’s still time to jump on this train.
Sure, it would’ve been better a few months ago (spoken like someone who bought Oklo stock back in June 2024 at around $8.5 per share, which now trades at $75.5, nearly a 9x return in just over a year). But the opportunity is far from over.
Nuclear Momentum Is Accelerating, And Governments Are Leading the Charge
Over the past seven months, interest in nuclear energy has exploded. Several nuclear-related stocks have posted double, or even triple, digit gains. But this isn’t just another speculative bubble, governments are taking real action.
In the U.S., for instance, President Trump signed four executive orders on May 23 focused on reviving the nuclear sector. The event at the White House included key industry stakeholders, including developers of Small Modular Reactors (SMRs), which are widely seen as the most promising nuclear tech going forward.
The takeaway? Momentum is building, and it’s being backed by policy, funding, and regulation.
“Did I Miss the Train?” Not Quite, Here’s Why It’s Still Early
Many investors might feel like nuclear is the next AI, something that’s already taken off. But unlike AI, which is full of promise but still searching for real-world business models, nuclear energy is proven, practical, and deeply needed.
Here are a few key reasons why this is still a ground-floor opportunity:
1. The Technology Race Is Wide Open
We don’t yet know which technologies will dominate (SMRs, fast reactors, fusion?), which companies will win, or which business models will scale profitably. This uncertainty may deter conservative investors, but for those willing to take some risk, it means plenty of upside.
2. Regulatory and Political Decisions Will Be Game-Changers
Nuclear is heavily regulated. In some countries, policies are already favorable; in others, they’re still under discussion. The good news? The global shift toward pro-nuclear regulation is real. Once key legislation and incentives fall into place, early movers could benefit massively.
3. We Know the World Will Need Way More Energy, We Just Don’t Know How Much
Between AI, electric vehicles, digital infrastructure, and even water desalination, global energy demand will skyrocket. Nuclear is one of the few technologies capable of delivering constant, large-scale, carbon-free power.
4. It’s a Vertically Diverse Sector
The nuclear ecosystem is broad and includes:
- Reactor developers and builders (like Oklo, NuScale, TerraPower)
- Uranium miners and enrichment companies (like Energy Fuels Inc.)
- Utility providers integrating nuclear into their energy mix
- Engineering and construction firms building critical infrastructure
This creates plenty of angles for investors, from hardware to materials to services.
5. The Fundamentals Are Real, Not Just Narrative
Unlike AI, which still struggles with commercialization in many areas, nuclear energy already powers entire countries. The historical drawbacks, high costs and long build times, are being addressed with new technologies like SMRs that offer faster deployment and lower capital requirements.
Case Study: Oklo
Let’s make it tangible. Just look at what’s happened with Oklo in the past few weeks.
The company has:
- Successfully completed the U.S. Nuclear Regulatory Commission’s pre-application review for its first commercial plant, the Aurora Powerhouse
- Signed a key agreement with Kiewit Nuclear Solutions Co., which will be the lead construction partner for the Aurora plant in Idaho (scheduled for 2027–2028)
- Announced a partnership with Liberty Energy to provide turnkey energy solutions that combine Liberty’s natural gas generation systems with Oklo’s advanced nuclear technology; this joint effort will initially rely on Liberty’s Forte natural gas generation and load management systems to meet immediate energy needs, while simultaneously laying the groundwork for the future integration of Oklo’s Aurora nuclear plants, offering zero-carbon baseload power in the years ahead.
In short: Oklo is no longer a future concept. It’s becoming an industrial reality.
What About Thematic ETFs?
I’m usually not a big fan of thematic ETFs. They tend to follow market hype and can expose investors to redundant fees and unbalanced portfolios.
But in this case, I’m willing to make an exception.
Here’s why:
- The sector is emerging, but not overhyped
- There are relatively few major players, making ETF exposure efficient
- It’s heavily influenced by government regulation, meaning individual stock picking could be more volatile
Thematic ETFs allow investors to gain exposure to a broad range of companies, from miners to utilities to reactor tech developers—without betting everything on one horse. They offer a way to ride the trend while spreading the risk.
If you’re new to the sector or simply looking for a diversified entry point, this is one of the rare cases where a thematic ETF actually makes sense.
Final Thoughts
The nuclear energy trend is solid, structural, and still in its early days. Yes, some valuations have already jumped. But we’re far from a mature or saturated market.
As always, risks remain—but for long-term investors looking to align sustainability, innovation, and energy demand, nuclear could be one of the most compelling bets of the decade.
