Bloom Energy Stock Has Surged 150% in 2026. Is It Still a Buy?

Bloom Energy shares have surged 150% year-to-date in 2026, rebounding sharply in August after a July selloff. The fuel-cell provider crossed $1 billion in quarterly revenue for the first time in Q2, driven by surging demand from AI data centers that prize BE's 'time-to-power' deployment advantage. Management issued 2026 full-year revenue guidance of $3.9 billion to $4.2 billion.

The rally has pushed valuation to 81 times forward earnings, a premium that reflects optimism around data center infrastructure buildout but leaves little room for execution missteps. Manufacturing constraints remain a potential bottleneck to meeting elevated demand, a risk flagged in the source analysis. The Motley Fool author maintains a bullish long-term stance despite acknowledging near-term volatility.
