American Fusion Inc. (OTC: AMFN) has released results from its latest series of experiments using the proprietary Texatron™ technology: a new high-voltage pulsed magnetic field configuration generated toroidal plasmas that were hotter and denser than those achieved in previous high-current experiments, while maintaining stability against magnetohydrodynamic instabilities throughout the experimental pulse.
The stability result is what matters most. Producing an extremely hot plasma is only half the challenge in fusion: the other half is keeping it together long enough to trigger the reaction. In this regard, Texatron™ operates through powerful electromagnetic pulses of extremely short duration, designed to simultaneously create three conditions: extreme plasma temperature, high pressure and density, and sufficient confinement time. The approach relies on rapid magnetic compression and shock heating in a pulsed regime.
Today’s announced results are part of a sequence of milestones that American Fusion is documenting step by step. In August 2026, the company had already reported achieving peak confinement pressures of approximately 100,000 atmospheres in repeatable magnetic confinement tests. The road to fusion is long, and the company itself is clear about the distinction between creating extreme plasma conditions, producing fusion reactions, achieving ignition, and ultimately generating usable net energy. Each phase is a separate milestone. The program focuses on demonstrating each stage sequentially.
The ultimate goal is deuterium–helium-3 (D-³He) fusion, an aneutronic reaction that produces far fewer high-energy neutrons compared to standard deuterium–tritium fusion. This makes it potentially cleaner and more manageable from an engineering standpoint, albeit harder to ignite. For upcoming tests, American Fusion plans quantitative measurements of plasma temperature, density, magnetic field strength, compression behavior, confinement time, and stability. The testing infrastructure is also expanding: a new portable vacuum chamber was delivered to the company’s development facility on August 26, 2026, ready for subsequent experiments.
The Texas-based company, headquartered in Southlake, is operating across two scales. It has already calculated the comparison between an 11-inch model — approximately 500 kW — and a 23-inch model rated at around 5 MW: the latter would have a modeled plasma volume 8.36 times that of the smaller unit, with a proportionally higher theoretical D-He3 reaction potential. The long-term commercial plan aims to make the Texatron™ Fusion Engine™ a modular, carbon-free energy platform, deployable across industrial and grid applications through a Power-as-a-Service model. If the upcoming quantitative measurement cycles confirm the reproducibility of today’s results, American Fusion will have solid data on which to build the next phase of the program.
