SpaceX’s Russell Index Inclusion Triggers Massive Passive-Fund Buying
6/26/2026, 9:23:35 PM
Core Event & Background
On June 26, FTSE Russell will add SpaceX (NASDAQ:SPCX) to its Russell U.S. indexes after its June 16 IPO at $135 per share. The stock rose to $225.64, closed Thursday at $153 and remains above the IPO price. The fast-entry rule lets qualifying megacap IPOs join U.S. indexes five trading days after debut, the first reconstitution of two scheduled this year.
Data & Market Activity
SpaceX’s market cap is about $2 trillion, with roughly $100 billion of shares publicly floated. Valuation is near 107 times projected 2025 sales, far above Nvidia’s 21 times. Index-tracking funds must buy roughly $3 billion of SpaceX shares—about 17 million shares—representing <= 1 % of fund weight at entry. Short interest is reported at 13 % of free float (? 83 million shares) by Ortex, while S3 Partners cites 5-7 %.
Official Statements
Catherine Yoshimoto of FTSE Russell said the reconstitution brings “no major rule changes” for the indexes. Jefferies analyst Steven DeSanctis called the turnover “dramatic” and said it justifies a twice-yearly rebalance. Vanguard noted SpaceX’s initial fund weight will be <= 1 % but could rise as insider shares become tradable. S&P Global confirmed the company remains ineligible for the S&P 500 due to unmet profitability requirements for the latest quarter and the trailing four quarters.
Criticism
Analysts note the gap between SpaceX’s 107-times sales multiple and more modest peer multiples, questioning price sustainability. High short interest combined with the anticipated $3 billion passive-fund purchase could spark a closing-auction squeeze similar to the 2020 Tesla addition to the S&P 500. The company posted a $4.9 billion net loss despite revenue growth.
Conflicting Reports & Gaps
Short-interest estimates vary: Ortex reports 13 % of free float, while S3 Partners estimates 5-7 %. Purchase-size forecasts also differ, ranging from $2.68 billion (Jefferies) to $3 billion (other analysts). The timing of fund orders—whether executed in the closing auction or after market close—has not been disclosed.
Verbatim Quotes
- “And the turnover is dramatic. That does argue for twice a year.” — Steven DeSanctis, Equity Analyst, Jefferies
- “no major rule changes” for the indexes. — Catherine Yoshimoto, Director of Product Management, FTSE Russell
- “The total reconstitution day trade is estimated at nearly $150 billion, which is why Friday is a "key liquidity day," said Melissa Roberts, analyst at Stephens.” — Melissa Roberts, Analyst, Stephens

Outlook
SpaceX will join the Nasdaq-100 in early July, prompting additional buying by ETFs such as Invesco QQQ. Coupon payments on its $25 billion bond series will begin later this year, adding a steady cash-flow obligation. Investors will watch the December Russell reconstitution for further weight adjustments and market impact.
