Nasdaq confirmed the addition on Friday, just weeks after SpaceX made its Nasdaq (NDAQ) debut on June 12. The move matters because major funds that track the Nasdaq 100, including Invesco QQQ Trust (QQQ) and Invesco Nasdaq 100 ETF (QQQM), typically need to buy shares of newly added companies to mirror the index.

J.P. Morgan (JPM) estimates SpaceX’s inclusion could draw about $4.3 billion in passive inflows. That could provide near-term support for the stock, especially as demand for exposure to high-profile AI and space assets remains strong.

On Friday, SPCX shares rose slightly, closing at $153.23.

Nasdaq Rule Changes Open the Door

The addition comes after Nasdaq, along with FTSE Russell and MSCI, relaxed some entry rules for major indices. The changes include requirements tied to profitability, the number of trading days after a company goes public, and the amount of stock available for trading.
