About Valar Atomics
Valar Atomics is a nuclear technology company developing modular high-temperature gas reactors fueled by TRISO particles for off-grid industrial power and clean fuel production. Headquartered in El Segundo, California, the firm plans gigasites hosting hundreds of 35 MW reactors to supply hydrogen and synthetic fuels to steel mills and chemical plants. Founded in 2022, Valar Atomics raised $10 million in seed funding and collaborates with the U.S. Department of Energy on advanced reactor demonstrations.

|---|---|---|---|---|---|
| Aug 2026 | Series B | Sequoia Capital (lead); Snowpoint Ventures; Point72 Ventures; Conviction; Riot Ventures; Atreides Management; Dream Ventures; HOF Capital; Valor Equity Partners; Apandion | $1B | $6B | Valar Atomics raised a $1,000 million Series B led by Sequoia Capital, with participation from Apandion Capital, Atreides Management, Conviction, Dream Ventures, HOF Capital, Point72 Ventures, Riot Ventures, Snowpoint Ventures, Valor Equity Partners, and other investors. Sequoia partner Shaun Maguire is joining the board, and the company also closed a separate $200 million credit facility led by Erebor Bank alongside J.P. Morgan, Crescent Cove, and Hercules Capital. Reports around the round indicated a $6 billion valuation. The financing is intended to support Valar Atomics’ push to move from operating a single test reactor in Utah to building small reactors on a production line and scaling toward “producing fleets” of nuclear reactors. The company describes itself as building small modular nuclear reactors and industrial nuclear power infrastructure. Valar Atomics is a three-year-old nuclear startup based in El Segundo, California. Prior to this financing, reports indicated it had raised about $450 million, including equity and debt, at a $2 billion valuation; separate reporting also noted total lifetime funding of about $600.5 million before the new round. |

| Nov 2025 | Series A | Day One Ventures (lead); Dream Ventures (lead); Snowpoint Ventures (lead) | $105M | - | Valar Atomics is a Hawthorne, CA-based nuclear startup developing compact, high-temperature gas reactors using TRISO fuel and helium coolant for applications like synthetic fuel production, data centers, defense, and space exploration. The company focuses on microreactors such as the 100-kWt Ward 250, with prototypes like Ward Zero (non-nuclear test reactor) completed and Ward One planned in the Philippines to bypass U.S. regulatory hurdles. It is involved in litigation against the NRC and aims to meet DOE's July 2026 operational goal for SMRs. In November 2025, Valar Atomics raised $130 million in a Series A round led by Snowpoint Ventures, with co-leads Day One Ventures and Dream Ventures, and participation from Palmer Luckey, Shyam Sankar (Palantir CTO), Contrary, Balerion, DTX, Crosscut, Triplepoint, and prior investors like Riot Ventures. This brought total funding over $150 million, following a $19M seed in February 2025 led by Riot Ventures. Funds will scale nuclear fission development, complete reactor prototypes in Utah, and advance testing/licensing. Public comparables like BWX Technologies had $2.7B revenue in 2024 and $17.7B market cap as of Nov 2025. The company positions against competitors like X-Energy ($700M round Feb 2025), Oklo, NuScale, and Nano Nuclear in the $1.5B+ SMR funding wave. |
| Feb 2025 | Seed | Riot Ventures (lead); Steel Atlas; Initialized Capital; Day One Ventures; Stephen Cole; AlleyCorp | $19M | - | Valar Atomics emerged from stealth in February 2025 with $19 million in funding from investors including Riot Ventures, coinciding with the completion of assembly of its first reactor prototype, Ward Zero. The startup, based in Hawthorne or El Segundo, California, develops helium-cooled, high-temperature gas reactors using TRISO fuel and silicon carbide elements, designed for mass production at 'gigasites' to power off-grid applications like data centers, industrial plants, hydrogen production, and synthetic fuel plants. The company aims to reduce nuclear reactor costs through a factory-like production model rather than bespoke construction, with an initial contract to pilot a test-scale reactor and build two full-scale ones in the Philippines via its local research institute subsidiary. By November 2025, Valar Atomics raised a $130 million Series A round led by Snowpoint Ventures, with co-leads Day One Ventures and Dream Ventures, and participation from Crosscut Ventures, Balerion, Contrary, DTX, Triplepoint, Palmer Luckey, Shyam Sankar, and prior investors like Riot Ventures, Initialized Capital, and AlleyCorp. Total funding exceeded $150 million, supporting deployment of the 100-kWt Ward 250 reactor, with projects including Ward One in the Philippines to sidestep U.S. regulations and a test reactor under construction in Utah targeting 2026 completion. Snowpoint's Doug Philippone joined the board. The company is also involved in a lawsuit challenging NRC licensing for SMRs and participates in a DOE program aiming for operational reactors by July 2026, with CEO Isaiah Taylor expressing confidence in being first to deploy an SMR in the U.S. Valar positions its technology for carbon-neutral synthetic fuels competitive with fossil fuels, potentially generating significant revenue from hundreds of reactors per gigasite—estimated at $1 billion annually per 100 reactors from fuel sales, scaling to $10 billion+ for 1,000 reactors—plus high-temperature process heat for industries like steel and chemicals. Amid SMR competitors raising over $1.5 billion pre-February 2025 (e.g., X-Energy's $700M), public nuclear firms like BWX Technologies trade at multi-billion valuations with established revenue, suggesting potential premiums for Valar if it proves its model. |
