SpaceX will be added to the Nasdaq-100 index at the start of trading on Tuesday, July 7, 2026 [4].
This inclusion marks a significant shift in how the benchmark index handles large-scale public offerings. By altering its eligibility requirements, Nasdaq has paved the way for massive passive-buying flows from index funds that must track the composition of the Nasdaq-100.
To facilitate this move, Nasdaq rewrote its rules to allow mega-IPOs to be included more readily [5]. This regulatory shift is expected to create approximately $4.3 billion in passive buying pressure for SpaceX shares [2]. Such a move ensures that large institutional funds are forced to acquire the stock to maintain their index weighting.
The market capitalization used for determining SpaceX's weighting in the index is approximately $75 billion [1]. This figure represents three times the company's raw float [1].
One of the primary vehicles affected by this addition is the Invesco QQQ fund. This fund, which tracks the Nasdaq-100, manages roughly $500 billion in assets [3]. Because the QQQ must mirror the index, the addition of SpaceX necessitates a substantial purchase of shares to reflect the company's new weighting.
Analysts said the rule change specifically targets the unique structure of mega-IPOs, companies with immense valuations but potentially restricted floats. By adjusting these rules, the exchange allows the index to reflect the actual economic scale of the company rather than just the shares available for public trading.

The inclusion of SpaceX in the Nasdaq-100 signifies a pivot in exchange governance to accommodate the 'mega-IPO' era. By decoupling index weighting from raw float, Nasdaq ensures that the world's largest companies can be represented in benchmark indices immediately upon listing. For SpaceX, this creates a guaranteed floor of demand from passive ETFs, reducing the volatility typically associated with new public listings while increasing the company's influence over the broader tech-heavy index.
