Shares of FuelCell Energy (NASDAQ:FCEL) are up 18% in midday trading on Monday, leading a broad rally across the fuel cell complex. Plug Power (NASDAQ:PLUG) stock is climbing 13%, while Bloom Energy (NYSE:BE) is rallying 12% as investors rotate aggressively into clean baseload power names.
FCEL stock is trading at around $16.41 after closing Friday at $13.70. Plug Power shares sit near $3.56, and Bloom Energy is changing hands at roughly $293, just shy of its 52-week high of $302.99.
The rally caps an extraordinary stretch for the sector. Through May 8, Bloom Energy stock was up 200% year to date (YTD) and an eye-popping 1,414% over one year, with FuelCell Energy up 87% YTD and Plug Power up 58% YTD.
AI Data Center Power Demand Fuels the Move
The single biggest catalyst remains the AI infrastructure buildout. Hyperscaler power needs have outpaced what utilities can deliver, with grid interconnection queues stretching 5 to 7 years, pushing customers toward on-site generation that Bloom Energy, FuelCell, and Plug Power can supply behind the meter.
Policy tailwinds are stacking on top. The 30% Investment Tax Credit extended through at least 2032 and 45Q carbon capture incentives keep capex math workable for fuel cell deployments, even as the 10-year Treasury yield sits at 4%.
Notably, the move is happening in a calm tape. The VIX is at 17.19, well off its March 27 peak of 31.05, suggesting this is sector rotation into growth rather than a defensive bid.
Bloom Energy Sets the Template
Bloom Energy reported a blowout Q1 2026 on April 28, with revenue of $751.05 million, up 130% year over year (YoY). Management raised FY26 revenue guidance to $3.4 billion to $3.8 billion.
The bigger story is commercial traction. Bloom Energy’s $5 billion strategic AI infrastructure partnership with Brookfield Asset Management and its Oracle collaboration have repriced BE stock as a primary AI power play. Total backlog now stands near $20 billion.
Bloom Energy CEO KR Sridhar asserted, “Bring-your-own-power has shifted from a slogan to a business necessity for AI hyperscalers and manufacturing facilities. This shift is secular and growing.” The valuation is rich, with Bloom Energy trading at 128x forward earnings.
FuelCell and Plug Power as Catch-Up Plays
FuelCell Energy is positioning aggressively for the same theme. Q4 FY2025 results posted revenue of $55.02 million, up 12% YoY, with FuelCell Energy CEO Jason Few declaring, “Our strategy is deeply focused on the data center market where we see significant opportunities for our efficient, resilient power solutions.” FCEL stock is up 148% over the past month.
Plug Power’s Turnaround Bet
Plug Power’s Q4 2025 print, delivered March 2, showed revenue of $225.2 million, up 18% YoY, and the company’s first positive gross margin in recent memory. New CEO Jose Luis Crespo is targeting full profitability by year-end 2028, supported by an $8 billion global sales funnel.
Retail enthusiasm is showing up too. A WallStreetBets thread on PLUG stock titled “Short squeeze on PLUG tomorrow and Wednesday?” registered a very bullish sentiment score of 82.
What to Watch
The fuel cell sector has a long history of parabolic rallies followed by sharp giveback when execution lags expectations. FCEL stock is still down substantially over the past decade, a reminder that capital intensity and dilution have repeatedly punished investors who chased prior moves.
The key catalyst going forward is conversion. Investors can watch for whether FuelCell Energy and Plug Power land hyperscaler contracts, and whether today’s gains hold into the close.
Prudent investors may want to size their positions modestly given the elevated risk of multi-day pullbacks. The next earnings prints and any data center contract announcements could shape the next share-price move for all three names.
