Meet the Vanguard ETF That Increased Its SpaceX Holding by 39% in 1 Month and Shows No Signs of Slowing Down

Exchange-traded funds are rapidly increasing their allocations to Space Exploration Technologies Corp. (SpaceX) as share unlocks expand the company's publicly traded float on the Nasdaq. Since its June 12, 2026 initial public offering, where only 5% of shares were initially tradable, the company's expanding float has triggered mechanical index adjustments and aggressive fund accumulation, despite SpaceX commanding a $2 trillion valuation. The Vanguard Communication Services ETF has emerged as one of the most aggressive institutional accumulators, boosting its position by 85.2% over two months from 632,077 shares on June 30 to 1,170,398 shares by August 31. This makes SpaceX the fund's eighth-largest holding, with projections indicating it will climb into the top three alongside Alphabet and Meta Platforms with an expected weighting between 15% and 20% once fully weighted by float market cap. This aggressive ETF buying pressure provides sustained capital inflow for SPCX shares independent of short-term price fluctuations, while dramatically restructuring the sector composition of major communication and broad-market growth funds.
