Pacific Fusion bets pulsed-power z-pinch wins fusion; $900M Series A, module validated

Pulsed-magnetic inertial fusion startup building a 156-module demonstration system that fires synchronized terawatt-scale electrical pulses at deuterium-tritium fuel targets to reach net facility gain.

Commercially viable fusion comes from industrializing Sandia's Z-machine approach — mass-produced pulser modules squeezing fuel — not new confinement physics.

$900M+ Series A led by General Catalyst (Nov 2024/Mar 2025), milestone-based; $1B Albuquerque Research & Manufacturing Campus

Founded in 2023 in Fremont, California by Eric Lander (Human Genome Project leader), Keith LeChien (former pulsed magnetic fusion lead at LLNL and inertial confinement fusion director at NNSA), Will Regan, and former national-laboratory colleagues, betting that decades of US government investment in pulsed power could be converted into an affordable energy system.

Came out of stealth in November 2024 announcing a $900M+ Series A led by General Catalyst with backers including Bill Gates. By June 2026 the company said it had completed its second set of technical milestones, validating a roughly one-third-scale module that delivered ~440 GW peak power and ~1.1 MV in 80 nanoseconds — which it calls the highest-power single-step pulser module ever demonstrated — after more than 1,000 qualification shots. In August 2026 it broke ground on its $1B Research and Manufacturing Campus in Albuquerque, New Mexico, and signed an MoU with DOE's NNSA on pulsed-power and high-energy-density science.

Still scaling: full-scale pulser module targeted for late 2026, with the 156-module Demonstration System at Albuquerque aiming for net facility gain by 2030.

The founders came from LLNL and NNSA's inertial confinement programs, giving them first-hand access to decades of pulsed-power data and national-laboratory partnerships.

Choosing proven pulsed-power physics over novel confinement concepts meant the main engineering risk was manufacturing scale, which the module design directly addresses.

The $900M milestone-based Series A funded hardware iteration and a 200+ person team without diluting the company's focus on delivery dates.

Positioning the module as a platform (also useful for x-ray, neutron and electromagnetic testing applications) creates revenue-adjacent uses while fusion scales.

A frontier-tech team can de-risk by betting on the boring, proven physics and making the breakthrough a manufacturing problem instead of a science problem.

As of September 2026, Pacific Fusion is executing its roadmap: the scaled pulser prototype is validated, the full-scale module is targeted for late 2026, the $1B Albuquerque campus broke ground in August 2026, and the company is scaling manufacturing at build centers in California and New Mexico. Net facility gain is targeted for 2030.
