Lebron already owned 2% of Liverpool as he joined with FSG on just that purchase in 2010. The total purchase prices was 493 million and James kicked in 6.5 million. The group turned down a bid to buy Liverpool in 2018 for 2.6 billion (it is probably worth more now). So he is increasing his investment in FSG and joining all of their investments instead of just Liverpool. Seems like a pretty logical move for a guy that has made it clear he wants to own a NBA team when he retires. This way he gets sports ownership experience, even if just as a minority partner, while also increasing his own financial portfolio and contact list.
