What I know of Truth Social is that the 3 billion number comes from their "expected" IPO of $50 per share, Trump's portion of the IPO would in theory at that IPO level equal $3 billion. However, this is a pure fantasy. First, Truth Social operates at a negative at current, per quarter, as of earlier this year, they were losing as much as $10 per active user (which by the way, seems near fucking impossible). The total number of registered Truther's or whatever the fuck they are, is right around 10 million; however, active users are only about 2 million.
So what the media would have you believe is that a platform with 2 million users, and no clear path to growth or profitability is somehow worth between 6 and 10 billion. and to top it off, they somehow lose money per user. Forgive me for calling bullshit. 2 million people isn't nothing, but billions, not so much, in actuality, not even hundreds of millions.
