Here's when SpaceX could show up in major indexes and popular ETFs after its IPO

SpaceX is preparing for a historic IPO with a valuation of up to $2 trillion and a $50 billion to $75 billion capital raise, making it the largest IPO ever. Due to its low public float of 2.86% to 3.75%, its inclusion in major indexes like CRSP Total Market (VTI) and CRSP Growth (VUG) will depend on float-adjusted weighting, with potential entry within five days of trading post-IPO." "article": "SpaceX is set to launch the largest initial public offering (IPO) in history, targeting a valuation of $1.75 trillion to $2 trillion and raising $50 billion to $75 billion in capital. The company’s public float, however, will be extremely low—between 2.86% and 3.75%—due to restricted shares held by insiders and early investors, creating challenges for index inclusion. Major indexes like CRSP Total Market (tracked by Vanguard’s VTI) and CRSP Growth (tracked by VUG) use float-adjusted market weighting to reflect tradable shares. SpaceX’s eligibility was confirmed after CRSP updated its methodology in April, allowing eligible IPOs to be added after just five days of trading. This could mean SpaceX appears in these indexes within a week of going public. The low float could lead to significant differences in SpaceX exposure across funds, as some indexes prioritize liquidity. For example, Microsoft and Nvidia float nearly all their shares (99.97% and 95.8%, respectively), unlike SpaceX. Investors relying on passive portfolios may see varying levels of exposure depending on the fund’s methodology. The timing of SpaceX’s inclusion will depend on its IPO schedule and trading performance. While the exact date remains uncertain, CRSP’s fast-track process suggests rapid integration if liquidity thresholds are met. This could mark a historic shift for passive investors, as SpaceX’s massive valuation reshapes market capitalization rankings.
