Bloom Energy closed at $252.84 on Friday and gained about 6% in after-hours trading after S&P Dow Jones Indices said it would join the S&P 500 before the Sept. 21, 2026 market open. The fuel-cell company has risen more than 191% in 2026, supported by rising electricity demand from artificial-intelligence data centers, commercial agreements with Oracle, Brookfield and AEP, and quarterly results that exceeded analyst expectations. Bloom Energy reported earnings of $0.78 per share and $1.07 billion in revenue in its latest reporting period, while investors also weighed its premium valuation, varied Wall Street targets and a securities class-action case concerning Chinese export restrictions and tariffs.
