Sequoia poised to lead $1 billion funding round for Valar Atomics at $6 billion valuation

Sequoia may lead a $1 billion equity round that could value Valar Atomics near $6 billion. The move would spotlight nuclear SMRs for AI data centers.

Valar Atomics, a startup developing small modular nuclear reactors (SMRs), is currently in talks for a new funding round. According to three sources close to the company, the expected deal valuation is around $6 billion, with Sequoia named as the anticipated lead investor.

According to The Information, which first reported the talks, the El Segundo, California-based startup is pursuing a $1 billion equity round.

Part of the previously raised capital was at a lower valuation: Valar raised $450 million – of which $340 million was in equity and $110 million in debt instruments – valued at about $2 billion, according to Bloomberg in March.

Deals structured in multiple tranches at different valuations are becoming increasingly common in AI-related investments. This structure can give the impression of a single valuation, but investors in the same round may pay different prices for the same company.

Sequoia and Valar Atomics declined to comment.

Earlier this month Valar demonstrated that its nuclear reactor delivered a small amount of power to Nvidia’s chip. At the same time Valar and Nvidia announced a partnership to use nuclear energy to power future AI-powered data centers.

Demand Context and Industry Competition

Valar’s growth is taking place against a backdrop of overall demand constraints: electricity demand for data centers is expected to rise significantly in the coming years, while power grids in many regions will need time to expand. In this context, nuclear energy has drawn attention as one of the key arguments in favor of infrastructure development for the AI industry.

Investors, Technology, and Regulatory Aspects

Among Valar’s investors are Isaiah Taylor, who founded the company; Palmer Luckey, founder of Anduril; and Shyam Sankar, Palantir’s Chief Technology Officer. Competitors and partners include Kairos Power and TerraPower (backed by Bill Gates), which are developing next-generation reactors for technical and industrial clients, as well as NuScale Power – the only SMR developer with an approved regulatory design in the United States. Last year NuScale received approval for an updated reactor design with higher power output.

Valar’s technology is based on a helium-cooled, high-temperature gas reactor. The company says it plans to eventually build hundreds of SMRs to power data centers, though the path from prototype to commercial scale will remain challenging.

On the regulatory front, Valar has taken an aggressive stance: last year the company joined a lawsuit filed by several states and competitors against the Nuclear Regulatory Commission, arguing that the regulator applies the same lengthy licensing processes to small test reactors as to full-scale commercial plants. The case is under consideration, and the parties periodically pause legal actions, which could indicate a potential settlement.

The founder of Valar is Isaiah Taylor, who left school at 16. Now 27 years old, he notes that before Valar he started two previous companies, and his great-grandfather worked as a nuclear physicist on the Manhattan Project.

The partnership with Nvidia and the potential funding round underscore investors’ interest in technologies that can support future AI infrastructure. The expected valuation of $6 billion could influence financing terms for nuclear SMRs and their use in data centers.

In the future we expect further development of nuclear SMR applications in data centers and the formation of new investment terms that will help bring the technology to the commercial market more quickly.
