Nuclear startup Valar Atomics in talks to raise new funding at $6B valuation

Key facts

• Valar Atomics is in discussions to raise new funding at a valuation of approximately $6 billion.
• Sequoia Capital is expected to lead the funding round.
• The company previously raised $450 million at a $2 billion valuation.
• Valar Atomics is developing small modular nuclear reactors (SMRs) to power AI data centers.
• Valar recently partnered with Nvidia to explore nuclear energy for future AI data centers.
• Valar is involved in a lawsuit against the Nuclear Regulatory Commission regarding licensing processes.

Valar Atomics, a three-year-old startup focused on developing small modular nuclear reactors (SMRs) for AI data centers, is reportedly in discussions to raise new capital at a valuation of approximately $6 billion. Sequoia Capital is expected to lead the deal, which could be around $1 billion, according to sources familiar with the company.

This potential funding round follows Valar's previous capital raise of $450 million, which included $340 million in equity and $110 million in debt, at a $2 billion valuation in March. The company recently demonstrated its reactor powering an Nvidia AI chip and announced a partnership with Nvidia to explore nuclear energy solutions for future AI data centers.

The demand for electricity to power data centers is projected to grow significantly, creating a market opportunity for nuclear power as a reliable energy source. Valar's technology is based on a helium-cooled, high-temperature gas reactor, with plans to eventually build hundreds of SMRs. However, the technology is still nascent, and the timeline for industrial-scale deployment remains uncertain.

Valar's founder, Isaiah Taylor, dropped out of high school at 16 and has previously launched two startups. The company is also engaged in a legal dispute with the Nuclear Regulatory Commission, arguing against the agency's licensing process for small test reactors. Other companies in the SMR space include Kairos Power and TerraPower, with NuScale Power being the only SMR developer holding U.S. regulatory design approval.
