Bloom Energy’s 190% Rally Runs on Revenue, Backlog and AI Power

Bloom Energy’s stock has climbed roughly 190% in 2026, but the rally is not resting on a single contract or a speculative hydrogen narrative. The arithmetic is more direct: quarterly revenue has crossed the $1 billion mark, management has doubled its full-year growth outlook, and artificial-intelligence developers are paying a premium for electricity that can arrive before the grid does.

The San Jose-based company reported $1.065 billion of second-quarter revenue, up 165.5% from a year earlier, while product revenue more than tripled to $935.4 million. Bloom also lifted its 2026 revenue guidance to $3.9 billion to $4.2 billion, implying roughly 100% growth at the midpoint. Non-GAAP operating income is expected to reach $800 million to $900 million, a sharp change for a company once valued primarily on a long-dated clean-energy promise.

The demand engine is power-hungry computing. Bloom’s solid oxide fuel-cell systems generate electricity on site from fuels including natural gas, biogas and hydrogen, allowing customers to sidestep transmission bottlenecks and lengthy utility interconnection queues. Oracle has agreed to procure up to 2.8 gigawatts of Bloom capacity, with 1.2 gigawatts already contracted, while Nebius plans a 328-megawatt deployment for its U.S. artificial-intelligence infrastructure.

That visibility has swollen Bloom’s reported backlog to about $20 billion, including roughly $6 billion of product commitments and $14 billion of service revenue. The comparison investors are making is simple: against $2.024 billion of 2025 revenue, the backlog represents nearly ten years of last year’s sales, although delivery schedules, financing and customer execution determine how quickly it becomes revenue.

There is a second mechanical tailwind. S&P Dow Jones Indices plans to add Bloom to the S&P 500 before trading begins on September 21, creating forced demand from index-tracking funds just as the company enters a higher-growth phase.

The risk is valuation. Investors are now underwriting rapid manufacturing expansion, sustained AI infrastructure spending and conversion of a large backlog into cash. Any delay would hit a stock whose expectations have outrun its old identity. Bloom is no longer being priced as a niche fuel-cell maker. It is being priced as an infrastructure bottleneck solution.
