# Pacific Fusion

> Pulsed magnetic inertial fusion company with more than $900M in milestone-based Series A commitments announced in October 2024; working toward net facility energy gain.

## Why it is interesting

Pacific Fusion's $900M headline refers to a very large 2024 Series A commitment arranged in milestone-linked tranches—not necessarily $900M already received as cash. The company's research and New Mexico demonstration facility are advancing, but it has not commercially generated fusion electricity. Its private valuation has not been disclosed.
