Data: Low

Inertia presents a strong upside opportunity (116% expected upside) driven by its unique, proven laser-based fusion technology and a massive, untapped market.

Last updated: February 25, 2026

Bull (30%)+400%

Inertia rapidly achieves key technical milestones, including successful demonstration of 'Thunderwall' and efficient mass production of fuel targets, attracting further significant investment and partnerships. This accelerates their path to a pilot plant, pushing valuation to $10B+ (5x current valuation) as a clear leader in commercial fusion.

Base (40%)+50%

Inertia makes steady progress on laser and fuel target development but faces expected engineering and regulatory challenges, extending timelines. The company maintains its lead in laser-based fusion, securing additional funding rounds at a moderate step-up, reaching a $3.0B valuation (1.5x current valuation) within 2-3 years.

Bear (30%)-80%

Significant technical hurdles or unexpected scientific roadblocks delay progress, or a competitor achieves a major breakthrough. High capital burn without sufficient progress leads to a down round, severely impacting common stock value, potentially reducing valuation to $400M (0.2x current valuation) or less.
