Bloom Energy stock surged 8.41% on September 3, 2026, as investors positioned ahead of an expected S&P 500 inclusion announcement. The fuel cell maker is among the top candidates for index addition, with S&P Dow Jones Indices expected to announce changes on September 6, 2026, according to Barron’s, with the new holdings taking effect on September 18–21.
The stock’s momentum reflects growing confidence in Bloom Energy’s dominance in powering artificial intelligence data centers. The company reported record second-quarter 2026 revenue of $1.065 billion, up 165.5% year over year, marking its first quarter above the $1 billion threshold.
Strong AI data center demand has become the core driver of Bloom Energy’s growth. The company’s backlog stood at $20 billion at the start of 2026, representing over 40 times its booked quarterly revenue at that time. Fuel cells provide reliable, on-site power generation for data centers, addressing both energy demands and grid constraints as AI infrastructure expands globally.
S&P 500 inclusion would expose Bloom Energy to significant passive index fund buying, a precedent that has historically boosted stock prices at the time of addition. When comparable companies were added to the S&P 500 earlier in 2026, such as Marvell Technology and Flex in June, index inclusion typically triggered rebalancing flows from the roughly $7 trillion in assets tracking the S&P 500.
Bloom Energy shares have climbed 182% year to date through September 4, 2026, though the stock remains about 30% below its June 2026 peak of $351.28 as investors weighed execution risks tied to the company’s ability to deliver on its massive backlog. The company introduced its Power Connect system in August 2026, cutting installation time by over 40%, a step aimed at accelerating deployment and revenue recognition.
The company’s eligibility for S&P 500 inclusion was confirmed after it met profitability and market-cap thresholds following strong Q1 2026 earnings in late April. Analysts covering the stock project an average 12-month price target of $275.08, suggesting modest upside from current levels, though estimates range widely from $97 to $390 per share depending on assumptions about data center growth and execution.
Bloom Energy faces competition from other fuel cell and power generation providers, but its first-mover advantage in securing AI data center contracts and its rapid revenue growth have positioned it as the sector leader. The company’s inclusion in the S&P 500 would mark a validation of its market position and likely draw additional institutional attention to the stock in the coming months.
