Bloom Energy, a fuel-cell company that had struggled for years in the renewable energy sector, has become one of the year's best-performing stocks by supplying power infrastructure to AI data centers. The company's revenue has grown from $1.3 billion(約2100億円) in 2023 to over $2 billion(約3200億円) in 2025, and analysts expect continued rapid growth as major cloud providers expand their data center power needs. However, the stock's 170× forward earnings multiple suggests investors have already priced in aggressive growth, making the sustainability of both the AI infrastructure boom and Bloom's business model key factors to monitor.

Bloom Energy, which specializes in solid oxide fuel cells, has shifted its business focus to serve the booming demand for reliable power at AI data centers. The company's revenue grew from $1.3 billion(約2100億円) in 2023 to over $2 billion(約3200億円) in 2025, with gross profits nearly tripling. Analysts project sales growth of 84.3% in 2026 and 72.6% in 2027.
Why it matters
After years of struggling to meet Wall Street expectations in the green energy sector, Bloom found a proven market in AI infrastructure. The data center industry's explosive growth in power consumption has turned the company's fortunes around, and it is expanding partnerships with major cloud providers like Oracle. This shows how AI's energy demands are reshaping traditional energy businesses.
What to watch
Bloom's stock currently trades at nearly 170 times forward earnings, suggesting investors are pricing in substantial future growth. Analysts expect earnings to more than double in 2026 (to $2.14 per share) and more than double again in 2027 (to $4.36 per share). Whether the company can deliver on these forecasts—and whether the AI data center boom sustains—will determine if the current valuation is justified.
