Often in these sorts of scenarios you can find an investment fund that has a stake in the non-public company that you are interested in and invest in the company by proxy by investing in the fund.
Wow! Do you happen to know any reputable ones where it'd be possible to single out (as much as possible, probably not possible completely) the investment into SpaceX?
Good luck with that considering most if not all of the other investments would be private investments that would be difficult, if not impossible to replicate in public markets.
Maybe you could find a bunch of other funds with slightly different positions in the same companies, and then form a linear combination that cancelled out the differences.
If I started a few listed companies and bought carefully constructed portfolios of unlisted securities specifically so that this would be possible, I wonder if the SEC would get mad.
I smell financial regulation. The secondary market is generally only available to accredited investors. If you're investing in a fund, that's one thing, but if a product is unwinding all of that to allow unsophisticated investors to essentially buy secondary stock in private companies, the SEC is going to have something to say about that.
