Space Exploration Technologies Corp. (SpaceX) will join the Nasdaq-100 index. The inclusion occurs after the market close on Monday, July 6, 2026. The change becomes effective on July 7. This move follows the company’s initial public offering on June 12.

Passive funds and ETFs tracking the index must purchase shares to rebalance their portfolios. Analysts estimate these funds will acquire billions of dollars in SpaceX stock. This mandatory buying serves as a significant near-term catalyst.

The demand could provide price support following recent stock volatility. The event highlights SpaceX's ascent as one of the largest publicly traded entities.
