It looks for all the world like a money-making scam. Obviously, the company is obscenely overvalued, and it's hard to believe that normal, responsible corporate governance would run an IPO at a value so far divorced from the realistic value of the company.
Then the fact that Trump owns so much of it when he's put virtually none of his own money into it. As far as I can see, the company just created a lot more shares and handed them to Trump. By diluting the value of the shares this way, investors aren't even really getting what they are paying for, although one can argue that's their problem: caveat emptor, et cetera.
Create a company, persuade people to invest to create a bubble, then... well. 1) Hope it maintains value long enough to cash out (Trump and colleagues are forbidden from selling up for six months). 2) Use it as leverage for loans, reduced interest rates. 3) Maybe none of these, it's just an ego trip, even if in the long run the value of the company will collapse. In non--scam world, possibly if people can throw enough money at it, it can be invested into other products - most realistically buying shares in other tech/media companies - to better justify its value.
(1) would be thoroughly despicable. Not least because the likelihood is that the "meme investors" are Trump supporters, and to cash out off them would leave them severely out of pocket when the company collapses in value to its natural level. Way to rob your own backers. But for someone like Trump, eminently doable because he is "king of the deal", proud of his ability to gouge other people for profit. It has to be incredibly tempting. Given that the company's only realistic asset is Truth Social (estimated value ~$20-30 million), even if the value of the firm dropped to $500 million at the point the initial investors fled, it would still represent a huge payday. So much for capitalism being about the efficient allocation of resources to meet the needs of society.
