SpaceX Is Joining the Nasdaq-100 This Week. What This Means for Invesco QQQ Investors.

Space Exploration Technologies (NASDAQ: SPCX), otherwise known as SpaceX, is joining the Nasdaq-100 index today. This means that exchange-traded funds (ETFs) tracking the index, including the Invesco QQQ Trust (NASDAQ: QQQ), will soon own the stock indirectly.

J.P. Morgan, part of JPMorgan Chase, expects this index inclusion to trigger about $4.3 billion in passive buying from index-tracking funds. Although this will serve as a clear near-term demand catalyst for SpaceX, Invesco QQQ Trust investors are also getting exposure to a founder-controlled company with a limited number of publicly traded shares (float) and an unprofitable business.

Why SpaceX's Nasdaq-100 entry matters for QQQ investors

Invesco QQQ Trust tracks the Nasdaq-100, which includes the 100 largest non-financial companies listed on Nasdaq.

SpaceX's quick entry became possible because the Nasdaq-100 changed its inclusion rules in 2026. Starting May 1, large newly public companies like SpaceX can be added after just 15 trading days if they rank among the top 40 eligible Nasdaq-listed companies. However, if only a limited number of shares are publicly traded, Nasdaq can limit how much weight the stock gets in the index. The change reflects today's market, where some very large companies stay private for longer and list with only a limited number of shares available for public investors.

SpaceX's Nasdaq-100 inclusion will give Invesco QQQ Trust investors exposure to the space, satellite broadband, and artificial intelligence (AI) infrastructure company before S&P 500 (SNPINDEX: ^GSPC) index fund investors get it automatically. Reuters reported that SpaceX would need at least 12 months of public trading history, generally accepted accounting principles (GAAP) profitability, and a public float of at least 10% before it can be considered for inclusion in the S&P 500. However, according to Reuters' estimates, SpaceX's public float is only 3% to 4%. The company also posted a $4.94 billion net loss in 2025.

Since only a small portion of SpaceX shares is available for public trading, buying by funds that track the Nasdaq-100 can have a bigger effect on the stock price. But once that buying is complete, the same limited supply of tradable shares can also make the stock move more sharply if investors start selling. So, Invesco QQQ Trust investors should ask whether SpaceX's Nasdaq-100 inclusion has already lifted the stock enough to limit its near-term gains.
