Valar Atomics has secured $1 billion in equity funding, led by Sequoia, at a reported $6 billion valuation, marking a significant follow-on round. This capital infusion, alongside a $200 million line of credit, will enable Valar Atomics to scale manufacturing of its small modular nuclear reactors (SMRs) following a successful demonstration powering an Nvidia Blackwell system and a development deal with Nvidia. Other investors participating in the round include Apandion Capital and Atreides Management.
