Bloom Energy (BE) joins the S&P 500 index on September 21 after a 150% gain in 2026. See how the fuel-cell firm’s AI data center deals are driving growth.
Bloom Energy (BE) will join the S&P 500 index on September 21, marking the first addition of an energy company to the benchmark since 2022 [2, 3]. The inclusion follows a 150% surge in the company's share price so far in 2026, driven by its role in providing on-site power for AI data centers [2, 3].

| 2026 YTD Performance | +156% [3] |

The move to the S&P 500 forces passive index funds to purchase Bloom shares to match the company’s new market-cap weight, creating a mechanical catalyst for the stock [2, 3]. This index inclusion coincides with a period of rapid expansion for the firm; Bloom reported 166% revenue growth in the second quarter, its strongest performance on record [2]. The company has raised its full-year revenue guidance to a range of $3.9 billion to $4.2 billion, which implies 100% growth at the midpoint [2].
Bloom’s growth is anchored by its position as a critical provider of on-site fuel cells for hyperscalers—large-scale cloud providers—that require immediate power solutions to bypass grid delays [2]. The company has secured a $25 billion financing framework with Brookfield to accelerate global deployments and an agreement with Oracle to supply up to 2.8 gigawatts of capacity [1, 2]. While these partnerships have fueled investor optimism, analysts note that the company’s valuation remains tied to the assumption that hyperscalers will continue their current pace of capital expenditure on data center infrastructure [2].
The company’s market activity has drawn scrutiny following public filings from the household of Nancy Pelosi. Disclosures show that Paul Pelosi purchased 10,000 shares and 100 call options on July 24, followed by an additional 5,000 shares and 100 calls on July 28 [1]. These transactions were publicly reported on August 21, two weeks before the S&P Dow Jones Indices announced the rebalance [1]. While the timing of the trades has prompted social media commentary, Bloom was already widely identified by market analysts as a leading candidate for S&P 500 inclusion due to its profitability and size [1].
Whether Bloom can sustain its current valuation depends on its ability to execute on its massive order book, as any slowdown in AI-related infrastructure spending could lead to a significant valuation correction [2].
