1 Stock I'd Buy Before NNE

Nano Nuclear Energy has generated huge returns, but it will take multiple years before commercialization even starts.Nano Nuclear Energy (NNE 3.15%) is well-positioned for artificial intelligence (AI) energy demands. Nuclear reactors offer a consistent energy source that prevents grid strains. As other AI stocks have demonstrated, gains can compound quickly once revenue starts to take off. However, Nano Nuclear Energy is multiple years away from commercialization. It has interest from AI data center, industrial, and military customers, but interest doesn't always translate into sales. The company has a lot to prove, but you can still ride the AI wave with plenty of small companies that are scaling quickly. Bitfarms (BITF 2.94%) is the better bet right now because its revenue is soaring. The crypto miner's push into AI data centers is gaining momentum, especially in light of a major transaction.

However, the growing need for AI infrastructure has caused many crypto miners to pivot to this service. Bitfarms is laying out the infrastructure that may support lucrative tech deals in a few years.

For instance, Cipher Mining (CIFR +0.39%) recently signed a 168 megawatt, 10-year deal with Fluidstack for $3 billion. Advertisement That means 168 megawatts is enough to generate $300 million per year. Bitfarms has 2.1 gigawatts of energy in its portfolio. Not all of it is energized yet, and the company is still allocating some of its energy for crypto mining. This full change should take a few years, but the company is already generating revenue. Its venture into AI data center infrastructure is already a proven business model. Bitfarms closed out Q3 2025 with 1,827 Bitcoin (BTC +0.35%), which comes to roughly $165 million. The company also has approximately $637 million in cash, which can help finance building and energizing its data center. Bitfarms sold its Paraguay data center to focus on North America The biggest AI deals have happened with data centers located in North America, and Bitfarms took a bold step to increase its exposure in the continent. The crypto miner recently sold its Paraguay data center for up to $30 million, depending on contract milestones being met. This move frees up capital and resources for Bitfarms to focus on its sites in Pennsylvania, Washington, and Canada. Approximately 90% of its 2.1 gigawatt pipeline is located in the U.S. The company is also in the process of converting its Washington site to an AI data center. This process should be completed in December 2026 and represents 18 megawatts of Bitfarms' energy portfolio. These conversions are expensive in the short run, but can lead to substantial annual recurring revenue. Bitfarms' business model is more proven in the marketplace than Nano Nuclear Energy. While nuclear energy companies are worth monitoring, investors may want to stick with a company that looks ready to win now instead of later.About the AuthorMarc Guberti is a Certified Personal Finance Counselor and has been a contributing Motley Fool stock market analyst since 2025.
