- Bloomberg Indices plans to add Bloom Energy to the Bloomberg 500 Index ahead of the opening bell on March 12
- Bloom Energy shares slipped roughly 4% in afternoon trading
- Data-center demand stands out as a major growth driver, the company says.
Bloom Energy Corp is set to be added to the Bloomberg 500 (B500) Index before trading kicks off on March 12, Bloomberg Indices announced Thursday. The inclusion places the fuel-cell manufacturer among the 500 U.S. firms with the largest float-adjusted market caps—meaning only shares available to the public are counted.
The timing’s key: when a company joins an index, funds that track those benchmarks often have to buy in, regardless of what’s happening at the business itself. Bloom’s addition comes as power supply for data centers dominates the market’s attention, with developers hunting for electricity and backup sources.
San Jose-based Bloom builds solid oxide fuel cells designed to deliver electricity via chemical reaction, not burning fuel. The firm pitches these as on-site power solutions, targeting commercial, industrial, and utility clients. So far, Bloom has rolled out roughly 1.4 gigawatts worth of its Energy Server systems at upwards of 1,000 sites across nine countries, Reuters reports in its company profile.
Shares of Bloom Energy slipped 3.8% to $158.47 Thursday afternoon, putting its market cap near $19.8 billion.
Bloom’s latest results show 2025 revenue landed at $2.02 billion, with the company forecasting 2026 revenue in the $3.1 billion to $3.3 billion range. CEO KR Sridhar described “bring-your-own-power” as “a business necessity,” and principal financial officer Maciej Kurzymski said, “We are confident in our trajectory.” Bloom Energy
The company has relied on big-ticket orders as a way to prove itself to clients demanding rapid power solutions. Back in January, American Electric Power revealed in a regulatory filing that a subsidiary took up an option for as much as 900 more megawatts of Bloom’s fuel cells—a detail first picked up by Reuters.
Bloom finds itself packed into a busy lane, up against rivals FuelCell Energy and Plug Power in slices of the fuel-cell market. Data-center operators, for their part, are still looking at mainstream picks—gas turbines, grid gear—from bigger industrial names.
The index operator says 11 names are joining the Bloomberg 500, while 14 head out. Joining Bloom on the roster: AST SpaceMobile, Ciena, Coherent, EchoStar, Flutter Entertainment, plus a handful of others.
But getting into the index doesn’t guarantee a rally. The rebalancing date can funnel trading activity into a narrow window, and stocks that are now more exposed to swings in sentiment could get knocked around by unexpected changes in project schedules, customer funding, or data-center buildouts.
The index entry date stands out as the next clear milestone. Beyond that, it’s all about new bookings and how deliveries shape up — that’s what typically determines if benchmark inclusion actually sticks.
