S&P Dow Jones Indices announced on September 4, 2026 that Bloom Energy, a maker of fuel cell power generators known as Bloom Energy Servers, will join the S&P 500 on September 21, 2026, the first energy sector stock added to the index since 2022. The news set off a surge in Bloom Energy options trading, with nearly half a billion dollars in premium changing hands in a single session, more than SpaceX traded in options that day. The move comes amid a broader September 13, 2026 market backdrop of rising US stocks, a sharply lower VIX, and investors watching the 10 year Treasury yield and upcoming inflation data.
