Nuclear energy startup Valar Atomics is in talks to raise $6 billion in new funding

Valar Atomics, a startup that builds nuclear small modular reactors (SMRs) — miniature power plants built in factories and designed to be cheaper and faster to deploy than conventional reactors — is in talks to raise a new round of capital, according to three sources familiar with the company. The three-year-old company is seeking a valuation of about $6 billion, and Sequoia is expected to lead the deal, the sources said.

The Information was first to report on the funding discussions, including that the El Segundo, Calif., startup is raising a $1 billion equity round.

A portion of that capital was previously raised at a lower valuation, the people told TechCrunch. Specifically, Valar raised $450 million — including $340 million in equity and $110 million in debt — at a valuation of $2 billion, per year. Bloomberg report In March.

Trades are structured in Multiple installments With different assessments, sometimes performed at different times, they are becoming increasingly common in today’s AI-fueled fundraising environment. These trades can create the perception that capital has been invested at a single, uniform valuation. In fact, investors in the same round can end up paying different prices for the same company — a distinction that matters more than ever as outsiders try to compare hot startups to each other.

Sequoia and Valar Atomics declined to comment.

Earlier this month, the company showed that its nuclear reactor provides a small amount of power to an Nvidia AI chip. In conjunction with this proof-of-concept demonstration, Valar and Nvidia announced a partnership to explore the development of nuclear energy to power future AI data centers.

The rise of the Valar is at odds with the broader demand crisis. Data center electricity needs are expected to grow sharply over the next few years, and utilities in many regions are years away from adding enough new capacity. This void has turned nuclear power — long plagued by cost overruns and regulatory bottlenecks — into one of the most watched corners of the AI ​​infrastructure boom.

It counts Valar Palmer Luckey, founder of Anduril, and Shyam Sankar, chief technology officer at Palantir, among its backers. Others chasing the opportunity include The power of Kairos and Terra Power (backed by Bill Gates), which builds next-generation reactors targeting technology and industrial customers, and NuScale Power, the only SME developer to receive US regulatory approval. (Last year he won consent To design an updated, higher-throughput reactor.)

Valar’s technology is based on a high-temperature, helium-cooled gaseous reactor. The company says it eventually plans to build hundreds of small and medium-sized modules (SMRs) to power data centers. But while SMRs are theoretically cheaper to manufacture than conventional reactors, the technology is still nascent and it is not at all clear how long it will take to deploy on an industrial scale.

In the background, Valar has taken an aggressive legal stance toward its regulator. Last year, it joined several states and their competing startups Sue the Nuclear Regulatory CommissionArguing that the agency is wrongly applying the same lengthy licensing process to small test reactors that it uses at full-sized commercial plants. (The issue has not remained unresolved, with both sides repeatedly halting litigation, suggesting some sort of settlement is in the works.)

The company was founded by Isaiah Taylor, who dropped out of high school when he was 16 years old. The 27-year-old said he was fired two Startups before Valar and proudly share them Great grandfather He worked as a nuclear physicist on the Manhattan Project.
