General Fusion completed its business combination with Spring Valley Acquisition Corp. III and began trading on Nasdaq as GFUZ (10 Jul 2026) — the first publicly traded pure-play fusion company. The de-SPAC (~$1B pro forma) was backed by a ~$107.5M PIPE plus trust proceeds.
General Fusion's Lawson Machine 26 (Richmond, BC), built and operational in ~16 months, compresses large-scale magnetized plasmas — including with a lithium liner — without superconducting magnets or lasers, the company's 'practical' MTF path. After first plasma it is pushing toward 100M°C and a Lawson triple product nTτ > 10²¹ in 2026; General Atomics is partnering on diagnostics.
General Fusion's LM26 magnetized-target machine mechanically compressed a magnetized plasma with a lithium liner, tripling electron temperature to ~8.4M°C (0.72 keV) — its first compressional-heating result, a concrete step on the in-progress path to a practical MTF demonstration (1 keV target next). Company-measured; results submitted for peer review.
