Brief

Valar Atomics, led by Isaiah Taylor, raised $1B at a $6B valuation (plus a $200M credit facility) to scale a small reactor Taylor built and named “Ward.” The Pentagon airlifted Ward 700 miles on three C-17s. Valar aims to replicate the reactor across “gigasites” to make energy 10x cheaper and use that power for direct‑air carbon conversion to fuels, while maintaining a heavily patriotic company culture and litigating against the NRC.

Why it matters

Valar Atomics closed a $1B Series B at a $6B valuation led by Sequoia (with Valor Equity Partners, Atreides, Point72, Conviction, others) and a $200M credit facility led by Erebor and JPM; Shaun Maguire (Sequoia) is joining the board.

Key details

  • Founder Isaiah Taylor — who grew up on food stamps, dropped out of high school at 16, and whose great‑grandfather worked on the Manhattan Project — built a working reactor named “Ward” before turning 28; the Pentagon airlifted that reactor 700 miles from California to Utah using three military C-17s.
  • Valar’s strategy is to mass-produce the reactor across nuclear “gigasites” to cut energy costs 10x and use the cheap power to pull carbon from air and convert it into oil and gas; the company has an explicitly patriotic culture (bible studies, raw milk, fast cars, cigar lounge, four large historical paintings) and has sued the NRC for slowing deployment.

ok this might be the most aggressively american startup i’ve ever seen 🇺🇸

> they’re trying to build nuclear reactors 100x faster than the nuclear industry ever has

> the founder isaiah taylor grew up on food stamps + dropped out of high school at 16

> his great-grandfather literally worked on the manhattan project

> generations later isaiah built a working nuclear reactor before turning 28 and named it “ward” after him

> the pentagon used 3 military c-17s to airlift the reactor 700 miles from california to utah in a first-of-its-kind mission

> the company culture is hardcore americana

> they hold bible studies, offer raw milk, love fast cars + have a cigar lounge

> plus 4 gigantic patriotic paintings of columbus discovering america, the pilgrims arriving on the mayflower, the signing of the declaration + the constitutional convention

> they sued the nuclear regulatory commission for slowing them down

> valar's end goal is to build the same reactor thousands of times across nuclear “gigasites” to make energy 10x cheaper

> then they'll use that energy to pull carbon out of thin air and turn it into oil and gas for supreme energy abundance

> just raised $1b at a $6b valuation to scale it

> if valar pulls it off, isaiah’s family will have helped usher in both of america’s atomic ages

yeah this gets my vote for most badass startup of the year

Announcing Valar Atomics' $1B series B led by Sequoia, with Valor Equity Partners, Atreides, Point72, Conviction, and others.

Alongside the $1B equity, we have closed a $200m credit facility led by Erebor and JPM.

I'm excited to welcome Shaun Maguire from Sequoia to our board.
