Broad-market funds like the Vanguard Total Stock Market ETF (VTI) and the iShares Core S&P Total U.S. Stock Market ETF (ITOT) include SpaceX.

SpaceX was added to the Nasdaq-100, meaning funds that track it, such as the Invesco QQQ ETF, hold the stock.

Benchmarks like the Russell 1000 also hold SpaceX, automatically populating funds like the iShares Russell 1000 ETF (IWB)
