Valar Atomics closes $1 billion Series B at $6 billion valuation

Valar Atomics closed a $1 billion Series B on August 3, led by Sequoia Capital at a $6 billion post-money valuation, with Sequoia partner Shaun Maguire joining the board. The round included a separate $200 million credit facility led by Erebor Bank and J.P. Morgan, and Valar said the roughly $1.2 billion in combined new financing will fund its shift from demonstrating its small reactor technology to producing reactors at volume for markets including AI data centers.
