Greece-born Milwaukee Bucks star Antetokounmpo has made the investment together with his brothers Thanasis, Kostas and Alex, the club said in a statement.
"My father was a professional soccer player, and it was the first sport I fell in love with in Greece," said Antetokounmpo.
"I've always had the dream of owning a soccer team. When my brothers and I explored Nashville SC, we knew it was a team and a city that we wanted to get involved with," he added.
