3 Nuclear Stocks To Own In October 2026

AI investment is speeding up so quickly that Anthropic’s Jack Clark is openly talking about US GDP potentially reaching US$44 trillion by 2030, which hints at an enormous leap in electricity demand. Constant, low carbon power becomes a scarce resource in that world. That is where nuclear focused infrastructure comes in. This article walks through three stocks tied to this long term, always on power story.

The three infrastructure stocks in this article are just a starting sample, as the full Nuclear Renaissance screen surfaced 13 more companies with equally compelling narratives that are not covered here.

To go straight to the source and identify which nuclear energy infrastructure plays best fit your thesis, analyze the Nuclear Renaissance screener.

Standard Nuclear (STDN)

Overview: Standard Nuclear designs, engineers, and manufactures TRISO advanced nuclear fuel for SMR and microreactor developers and US federal nuclear programs.

Operations: Standard Nuclear currently generates about US$7.5 million from TRISO production, with roughly US$7.4 million of that coming from customers in the United States.

Market Cap: US$1.9b

Standard Nuclear matters for the Nuclear Renaissance theme because its TRISO fuel sits directly in the supply chain for 24/7 carbon free reactors that data centers and decarbonizing grids are looking to lock in for decades.

"Planned authorization to operate the SN-TN and SN-ID facilities in 2026, combined with existing SN-Z output, is expected to lift Standard Nuclear’s TRISO throughput capacity to up to 2.5 metric tons per year. This directly supports higher potential product sales and associated gross profit."

What happens if one less visible constraint quietly reshapes how much of that future volume actually lands on the income statement.

That hidden bottleneck is exactly what the full narrative for Standard Nuclear unpacks, showing how capacity, contracts and policy could be accelerating or quietly capping Standard Nuclear’s upside.

Cameco (TSX:CCO)

Overview: Cameco supplies uranium fuel and nuclear technology services that help keep commercial reactors running as round the clock, low carbon power sources.

Operations: Cameco generates about CA$2.9b from Uranium, CA$551 million from Fuel Services, and a further CA$3.4b from Westinghouse, partly offset by unallocated adjustments.

Market Cap: CA$51.4b

Cameco matters for the Nuclear Renaissance theme because its uranium production and long term contracts underpin the fuel supply AI hungry reactors rely on.

"Momentum in utility contracting remains a live driver. Long-term uranium contracting is still below replacement rates, and Cameco is deliberately limiting new contract volumes while pushing for higher floors in the high US$70s per pound and ceilings around US$160 per pound on longer-tenor deals."

What happens if a single shift in how those contracts are structured quietly rewrites the long term economics of Cameco’s uranium business?

That contract twist is exactly where the full narrative for Cameco shows how pricing floors, ceiling bands and fuel cycles could be quietly reshaping Cameco’s long term uranium leverage.

TKMS & Co KGaA (XTRA:TKMS)

Overview: TKMS & Co KGaA builds conventional submarines, surface warships, and sensor systems that support nuclear-powered fleets and maritime defense missions.

Operations: TKMS generates about €1.3b from Submarines, €543 million from Surface Vessels, and €833 million from Atlas Electronics, partly offset by segment adjustments.

Market Cap: €5.3b

TKMS & Co KGaA matters for the Nuclear Renaissance screen because its submarines, surface vessels, and sensor suites help secure nuclear-powered fleets and the critical sea lanes behind always on power infrastructure that AI data centers increasingly depend on.

"It can be said that TKMS has a dominant position in Europe, there is an arms boom underway, and the launch of a new arms company on the market is attractive; not many arms companies manufacture submarines."

One unresolved pressure on profitability may quietly determine how much of that nuclear-aligned naval demand actually reaches future earnings.

That pressure point is exactly why the full narrative for TKMS & Co KGaA digs into how TKMS & Co KGaA’s order book, pricing power and defense spending cycles could shape earnings potential.
