Won't happen due to index funds. If they get approval to be publically listed, a bunch of index funds, as a condition of the financial security package they're selling, will be forced to buy stock to keep their index aligned with the overall market positioning.
It's basically the Space X scam all over again with the large brokerages in on it knowing that it's primarily consumer investors who dropped money into these index funds. The intention is to keep adding a bunch of shitty companies to the market so that the actual big name traders can use it to siphon off the huge glut of wealth in those index funds into their wallet by selling shares at massively overpriced values that they know won't hold up.
