First of all, SPAC means Special Purpose Acquisition Corporation.
SPACs was a major focus of one company of another famous U Miami benefactor billionaire. Think Frost music school and Frost Band of the Hour: Philip Frost.
If I'm not mistaken, Ruiz sold about 1% of one of his companies (MSP RECOVERY) for about $330 million in value. Hence, Ruiz's company (outside of the SPAC: LIONHEART <ticker: LCAP nasdaq>) would be technically valued at about $33 billion!!!
The SPAC has gone up in value since he sold his 1%, so his Net Worth Computation, I assume, would have risen (on paper) to his percentage ownership of MSP multiplied by about $35 billion.
If he owns 70% of MSP, and the MSP owners got cash for selling the ~1% to LIONHEART, then he got about $230 million in cash, and a paper valuation for his remaining MSP ownership of about $23 billion.
This is all what I understand from personal experience regarding SPACs and a quick glance at an article yesterday about Ruiz, LIONHEART and MSP RECOVERY.... so I apologize if I have misread, or misinterpreted anything!!
