Space Exploration Technologies Corp. (NASDAQ:SPCX) will be added to the Nasdaq 100 index before the opening bell on July 7, 2026, Nasdaq confirmed, following FTSE Russell's inclusion of SpaceX in its US equity indexes effective after Friday's closing bell.

Key Highlights

• SpaceX will join the Nasdaq 100 before trading opens on July 7, 2026, placing it among the 100 largest non-financial companies on the Nasdaq exchange.

• FTSE Russell added SpaceX to its US equity indexes after Friday's close as part of its semi-annual reconstitution, triggering an estimated $3 billion or more in required passive fund purchases.

• SpaceX debuted on the Nasdaq on June 12, 2026, in what is widely reported as the largest IPO in history, raising approximately $75 billion and opening with a valuation near $1.77 trillion.

• The stock edged up approximately 0.15% on Friday as passive index fund buying ahead of the Russell inclusion began pricing in, though shares have fallen more than 30% from their post-IPO peak.

Less than three weeks after completing the largest initial public offering in history, SpaceX is being added to two of the most closely followed US equity benchmarks simultaneously. FTSE Russell triggered its inclusion after Friday's close as part of the index provider's semi-annual reconstitution, using a fast-track rule adopted in late May that allows large IPOs to enter Russell US indexes after just five trading sessions. The Russell changes go live for trading on Monday, June 29.

The Nasdaq 100 inclusion, effective July 7, will follow under a separate fast-track framework Nasdaq adopted on May 1, reducing the standard 15-trading-day seasoning requirement. SpaceX cleared that threshold with ease given the scale of its float and trading activity since listing. Over $800 billion in assets tracks the Nasdaq 100, including the Invesco QQQ Trust, making the SpaceX addition a meaningful mechanical event for index fund managers who must buy shares in proportion to the company's weighting.

Estimates for the total passive buying required from Russell-tracking funds range from roughly $3 billion on the conservative end to as high as $22 billion to $27 billion when accounting for the full universe of Russell 1000-linked mandates. Nasdaq 100 inclusion adds another layer of non-discretionary demand. SpaceX's publicly tradable float remains small relative to its total market capitalization, as Elon Musk retains near-total control through a dual-share structure, meaning even a modest index weighting could require meaningful purchases from passive vehicles.

SpaceX remains ineligible for the S&P 500, which declined in June to adopt fast-track rules or waive its profitability and seasoning requirements. That decision defers the largest potential wave of forced buying until at least mid-2027, creating a two-phase demand structure for the stock.
