Bloom Energy (NYSE:BE) shares are rallying midday Wednesday after Nebius Group named the fuel cell maker as its behind-the-meter power partner for a flagship AI data center. Bloom Energy stock is up 13% to $238, extending a torrid run that has the shares up 171% year to date (YTD).
The move is dragging the broader fuel cell complex higher. FuelCell Energy (NASDAQ:FCEL) shares are climbing 11% to $21.35, while the Global X Hydrogen ETF (HYDR) is advancing 4% to $46.13. Plug Power (NASDAQ:PLUG) shares are lagging at up 3% to $2.29, a reversal from Tuesday’s 10% lead on Plug Power’s Q2 2026 margin turnaround and raised 2026 guidance.
The setup is a role reversal from a day ago. Yesterday’s rally was a Plug Power single-name story. Today, Bloom Energy holds the concrete data center win, and the theme is participating around it.
Nebius Partnership Fuels Bloom Energy’s Data Center Thesis
The catalyst arrived on the Q2 2026 earnings call from Nebius Group (NASDAQ:NBIS | NBIS Price Prediction), the NVIDIA-backed AI cloud operator. Nebius management said switching the power source to Bloom Energy fuel cells “significantly enhances” its planned 300-megawatt Vineland, New Jersey AI data center, calling the units “an on-site power solution delivering reliable power quietly and ultra-low emissions,” with “no significant impact” on the project timeline.
The Vineland site had faced permitting, zoning and community opposition tied to proposed on-site gas generation. Nebius said the Bloom partnership helps it “unlock and expedite” sites, and reiterated a goal of raising its contracted-power target to 5 gigawatts by year-end 2026. The comments came from Chief Commercial Officer Tom Blackwell and Chief Product and Infrastructure Officer Andrey Korolenko.
The Nebius win reinforces the narrative CEO KR Sridhar laid out at Bloom Energy’s July 28 earnings report, when he stated that “all the major US hyperscalers and over a dozen US neoclouds, AI labs, and colocation data center operators have validated and approved our power solutions for their AI factories.” Bloom Energy’s Q2 2026 revenue landed at $1.07 billion, up 165.5% year over year (YoY), with product revenue up 215.4%.
Sector Re-rating, With FuelCell Riding the Read-Through
FuelCell Energy has no company-specific driver Wednesday. The move is a sympathy read-through off Bloom Energy and the broader push to solve AI data center power constraints with behind-the-meter distributed generation. FuelCell Energy stock is up 192% YTD, reflecting how quickly capital is rotating into fuel cell names once the AI power narrative firms.
The HYDR move matters as a theme indicator. The ETF is concentrated in the same three U.S. names driving today’s move, with Bloom Energy at 15.5%, Plug Power at 10.8%, and FuelCell Energy at 7.2% of net assets. Given that concentration, HYDR’s 4% lift is more of a direct pass-through than a diversified sector signal, but the theme is clearly participating today rather than sitting out.
NVIDIA (NASDAQ:NVDA) shares are up 3% to $223.14, representing a passing tailwind. The chipmaker is a strategic backer of Nebius, and Nebius stock itself is surging 26% to $243.54 after the Q2 report.
What to Watch Now
Bloom Energy’s analyst target price sits at $273.51, still above the spot price, but the shares carry a P/E ratio of 284.64x and a beta of 3.832. Meanwhile, the options positioning is mixed: the full-chain put/call ratio reads 1.5, with hedging concentrated in later-dated tenors.
Investors can watch for whether Bloom Energy stock holds above the $235 area into the close, and for follow-on hyperscaler and neocloud order flow that would validate the “standard for AI onsite power” framing. A confirming push in HYDR would signal that the theme, not just the stock, is re-rating.
