If you think that is bad, look into the spacex ipo. That tiny public offering is for stock that can barely vote and cannot bring shareholder actions, making them more NFTs than proper "shares" imho.
I know about voting shares and shareholder actions in US stock because they are somewhat frequently sited in all press and media. I just didn't know about sub 10% float.
I know there are plenty of ways to go around it via trust funds or other entities to hide it so the ownership could be extremely concenrtated. But having it actually allowed is something I didn't know.
This also makes the founder net worth of around $33B.
