Index Funds to Increase Holdings in SpaceX Despite Recent Stock Decline
U.S. retirement accounts and index funds are set to increase their holdings of SpaceX stock following the unlocking of insider shares on August 6, 2026. This development comes despite a significant 31% drop in July 2026. The release of over 911 million previously restricted shares has expanded SpaceX’s float-adjusted market capitalization, which is used by major indexes like the Nasdaq-100 and Russell 1000 to determine position sizes. The next rebalancing events—Nasdaq-100 in September 2026 and FTSE Russell on December 11, 2026—are expected to increase SpaceX’s weight within these indices. Morningstar estimates that the float expansion could push its weighting from around 1% to over 3.5%. Analysts warn this may lead index funds to buy more shares even as insiders begin selling. SpaceX entered major indexes quickly after its June IPO, triggering billions in forced buying by passive funds despite concerns about a rushed timeline and valuation issues.
