After completing the most substantial initial public offering in history, Space Exploration Technologies Corp. (SpaceX) has found its way into an expanding array of exchange-traded funds (ETFs). Currently, SpaceX is held within 148 ETFs as of early July and holds a top-15 position in 35 of these funds. Elon Musk's aerospace giant is growing in popularity among ETFs, particularly those allowing significant exposure to such high-profile stocks. Dedicated space-focused ETFs are also increasingly incorporating SpaceX. However, it's not only specialized funds that now contain SpaceX. Some ordinary index funds now include SpaceX due to changes in inclusion criteria prompted by the company's IPO. Crucially, major index providers such as S&P Dow Jones Indices opted not to immediately integrate SpaceX into their indices, implying that traditional S&P-related funds, such as the Vanguard S&P 500 ETF, will not include SpaceX until at least June 2027. Other index funds, particularly those aligned with FTSE Russell, have adopted SpaceX into their benchmarks. Notable entrants include the Russell 1000 Index, contributing to SpaceX's appearance in influential ETFs like the iShares Russell 1000 ETF and the Vanguard Russell 1000 ETF, managing approximately $59 billion in combined assets. The Vanguard Total Stock Market ETF, one of the most pivotal in the U.S., added SpaceX through its underlying CRSP US Total Market Index. Despite this inclusion, SpaceX occupies only a minor position in these ETFs, reflecting its limited trading float estimated between 3% and 5%. Beyond FTSE, MSCI indices have also expedited SpaceX's entrance, making it part of their flagship indexes such as the MSCI USA and MSCI All Country World Index. The latter, followed by the expansive iShares MSCI ACWI ETF, allocates a minor 0.08% to SpaceX. Meanwhile, investors focused on sector ETFs should note MSCI's dominance in benchmarks, with SpaceX occupying 2.2% of the Fidelity MSCI Communication Services Index ETF. As more of SpaceX's shares become publicly available, the stock's role within these funds is poised to grow. This trend could significantly reshape the allocation percentages in sector-specific ETFs, signaling broader market changes.
