Power for AI, delivered on site.
Bloom's solid oxide fuel cells let data centers make their own power instead of waiting years for a grid connection. Revenue hit $1.07B last quarter, up 166%, and 2026 guidance was raised twice to $3.9–4.2B. Oracle, AEP and all major US hyperscalers are customers or have validated the product.
Price, last 12 months
Daily closes with the 50-day average. The stock ranged from about $76 to $351 over the past year, with a beta near 3.8.
Revenue and margins, by quarter
Revenue in US$ millions, with GAAP gross margin on the right axis. Bloom's revenue is lumpy and Q4-heavy because it is booked as systems are installed. The last bar is about half of the second-half revenue implied by the full-year guide.
