Nuclear Renaissance: Why Big Tech Is Betting Billions on Atoms

AI has an energy problem. And Big Tech is solving it with nuclear.

Microsoft just paid to restart Three Mile Island. Google signed with Kairos Power. Amazon has a letter of intent with Oklo. Oracle's Larry Ellison is publicly discussing nuclear data centers.

When the world's most valuable companies all move the same direction, you pay attention.

Here's how to invest in the nuclear renaissance — and which stocks are actually worth buying.

Why Nuclear, Why Now?

AI Is Hungry

A single ChatGPT query uses 10x the energy of a Google search. Training GPT-4 consumed the equivalent power of 3,000 households for a year.

Data centers already use 2-3% of U.S. electricity. By 2030? Estimates range from 7-12%.

Renewables can't scale fast enough. Solar and wind are intermittent. Battery storage is expensive. Grid infrastructure is bottlenecked.

Nuclear offers:
- 24/7 baseload power
- Zero carbon emissions
- 90%+ capacity factor
- Small land footprint

Every PPA validates the thesis. Watch for more announcements.

Small Modular Reactors: The New Nuclear

Traditional nuclear plants cost $10B+ and take a decade to build. SMRs change the equation:

• Smaller: 50-300 MW vs. 1,000+ MW traditional
• Factory-built: Ship to site, assemble
• Faster: 3-5 year deployment
• Safer: Passive safety systems

The SMR Stocks

NuScale Power (SMR) — First Mover, Rocky Road

The pitch: Only NRC-certified SMR design in America.

The problem: Their flagship project (CFPP) was cancelled in 2023. Customer pipeline uncertain. High cash burn.

Verdict: Regulatory moat is valuable, but needs to land customers. High risk.

Oklo (OKLO) — The Altman Bet

The pitch: Sam Altman-backed. Amazon LOI. Advanced fuel cycle that uses nuclear waste.

The risk: Pre-revenue. NRC license still pending.

Verdict: Highest beta SMR play. The Amazon LOI is real validation. Binary outcome.

Centrus Energy (LEU) — The Sleeper Pick

Here's what most investors miss:

Every U.S. SMR needs HALEU fuel (High-Assay Low-Enriched Uranium).

Centrus is the ONLY domestic source.

Why this might be the best nuclear play:
- Wins regardless of which SMR company succeeds
- Actually profitable (unlike reactor developers)
- Government contracts for fuel production
- Picks-and-shovels, not lottery ticket

Verdict: Highest conviction nuclear play. If SMRs succeed, LEU wins.

Uranium Miners: The Fuel Play

If nuclear grows, uranium demand grows. Supply has been constrained for years.

Cameco (CCJ) — Blue Chip Uranium

• Largest Western uranium producer
• Westinghouse JV (fuel fabrication)
• Profitable, liquid, institutional-grade
• Market Cap: ~$24B

Verdict: Conservative uranium exposure. Best risk/reward for institutions.

Uranium Energy Corp (UEC) — U.S. Production

• Largest U.S. uranium mining capacity
• Production restart underway
• Higher beta than Cameco
• Market Cap: ~$3.0B

Sprott Physical Uranium Trust (SRUUF)

• Holds ~66M lbs physical uranium
• Pure price exposure
• No mining/operational risk

Verdict: Trade uranium price directly.

Position Framework

The Picks-and-Shovels Approach: If you believe in nuclear but don't want to pick winning reactor designs, LEU + CCJ gives you exposure regardless of which SMR company wins.

Bottom Line

• Conservative: Cameco (CCJ) — blue chip uranium
• Highest conviction: Centrus (LEU) — monopoly on SMR fuel
• Highest beta: Oklo (OKLO) — the Altman/Amazon bet

The nuclear renaissance is real. Big Tech's energy crisis demands it. Position accordingly.
