Sidenote: SpaceX actually is sorta-kinda publicly traded. Alphabet and Fidelity bought ~10% of SpaceX. Fidelity has a few mutual funds that are partially invested in SpaceX (like 0.5% of the fund is SpaceX). I'm kinda surprised someone hasn't made a FauxSpaceX ETF that buys the Fidelity SpaceX fund and does some shorts/options to try and cancel out the non-SpaceX parts of the fund.
