- SpaceX is entering the Nasdaq-100 only 15 trading days after its IPO began trading, as the world's largest IPO, pulling it into one of the market's biggest passive-investing machines.
- JPMorgan estimates roughly $4.3 billion of passive demand tied to Nasdaq-100 inclusion, while BNP Paribas puts potential Nasdaq-100 tracker buying closer to $8 billion.
- Only a small slice of SpaceX shares is available for public trading, with the rest held by insiders, employees, early investors, and other locked-up holders not yet free to sell.
- Index-fund buying arrives first; a major share unlock hits in August, with larger waves of tradable shares arriving later in 2026.
- After becoming "retail's biggest IPO trade," SpaceX stock surged 50% in its first three trading days before giving nearly all of it back over the following three days.
- The next technical price test sits at the $172 to $180 zone — a break above puts the record closing high just above $200 back in play, while a move under $150 turns the chart bearish.
Why it matters: SpaceX investors are looking at a timing mismatch: roughly $4.3–$8 billion in forced passive buying arrives now, but the real test of demand comes later when locked-up shares unlock starting in August. The thin float can prop up the price short-term, yet the same index mechanics that create forced demand also guarantee a wave of supply once insiders and early investors are free to sell.
