Bloom Energy shares jump 754% as AI power demand surges
Polen Capital has flagged Bloom Energy as a primary solution to data center power constraints, a thesis that has driven the fuel cell maker's stock up more than 750% over the past year.
Bloom Energy closed at $226.26 on July 21, registering a 753.68% gain over the past 52 weeks. The dramatic appreciation reflects a broader market pivot toward companies that can solve the physical infrastructure bottlenecks created by artificial intelligence. Investors are specifically betting on Bloom's solid oxide fuel cell systems to deliver reliable, on-site electricity for data centers.
"As demand for electricity is expected to accelerate, particularly from Al-related infrastructure, we believe Bloom remains well positioned to help address power constraints through its distributed energy solutions," Polen Capital wrote in its second-quarter 2026 investor letter. The firm highlighted that during the quarter, shares rallied as investors focused on the company's expanding opportunity set tied to data center buildouts.
Despite the staggering annual return, the stock's recent trajectory underscores its speculative nature. Over the past month, shares have fallen 29.63%. The company now holds a $65.27 billion market capitalization, having traded in a wildly volatile 52-week range between $25.74 and $351.28.
Fundamentals are growing, though not at the pace of the stock's valuation. The fuel cell maker generated $751.1 million in quarterly revenue, up 13.4% from the previous year. Institutional investors are taking notice, with 91 hedge fund portfolios holding the stock at the end of the first quarter, a slight increase from 88 in the prior quarter.
Bloom's rise occurred against a backdrop of renewed risk appetite for smaller companies. Polen's 5Perspectives Small-Mid Growth Strategy posted a 28.4% gross return in the second quarter, outpacing the 24.0% return of the Russell 2500 Growth Index. The firm noted that mid-cap growth stocks delivered one of their strongest quarterly performances in 25 years. This rebound was driven by easing macroeconomic fears and continued capital deployment from hyperscalers. Polen argued that this spending has firmly validated the artificial intelligence infrastructure cycle, creating lasting opportunities across power generation, grid infrastructure, and electrification alongside other secular themes like aerospace and defense modernization.
