Shares of FuelCell Energy, Plug Power, and Bloom Energy rallied sharply, driven by rising demand for clean power in AI data centers and strong financial results. Bloom Energy raised its 2026 revenue guidance after a 130% YoY Q1 revenue jump, while FuelCell and Plug Power focus on securing hyperscaler contracts amid favorable tax incentives. Despite recent gains, investors should watch for contract wins and earnings updates, as the sector is known for volatile rallies and pullbacks.
