Aalo Atomics has secured $100 million in funding to develop nuclear reactors designed specifically for AI data centers. The company says the money will go toward building small, advanced reactors that can meet the surging electricity demands of artificial intelligence workloads.
Why AI data centers need new power sources
AI training and inference require enormous amounts of energy. Data centers already consume roughly 1-2% of global electricity, and that share is expected to climb sharply as more companies deploy large language models and other AI systems. Traditional grid connections often can't keep up, and renewable sources like wind and solar aren't always available around the clock. Nuclear power offers a carbon-free, always-on alternative — but conventional reactors are huge, expensive, and take years to build. Aalo Atomics is betting on smaller, modular reactors that can be sited closer to data centers and brought online faster.
What Aalo Atomics plans to build
The company is working on a new class of nuclear reactors that are smaller than traditional plants. These units are designed to be factory-built and shipped to locations where they can plug directly into data center power systems. The reactors would provide steady baseload electricity without emitting greenhouse gases. Aalo Atomics hasn't released technical specifications or a timeline for its first commercial unit, but the $100 million raise suggests it's moving from the design phase toward prototyping and licensing.
The funding round and its backers
The $100 million came from a group of investors. Aalo Atomics did not name specific backers in its announcement. The company said the funds will be used for engineering, regulatory work, and early-stage construction. Nuclear projects face heavy oversight from the U.S. Nuclear Regulatory Commission, and getting a new reactor design approved can take years. The company will need to navigate that process before it can sell power to any data center operator.
AI companies are hungry for reliable, clean power. Microsoft, Google, and Amazon have all signed deals to buy electricity from nuclear plants or invest in next-generation reactor startups. Aalo Atomics is entering a crowded field that includes firms like NuScale Power, TerraPower, and Oklo. The difference, the company argues, is its focus on the specific power needs of AI data centers — not just general grid supply.
The company has not disclosed a timeline for when its first reactor might be operational. It also hasn't said which data center operators it's in talks with. Those details will likely emerge as the project moves through the regulatory process.
