Walmart heir Rob Walton is expected to purchase the Denver Broncos for roughly $4.5 billion, according to a report.

The winning bid hasn't yet been finalized, but it's expected to be announced as "early as this month."

If the final sale price is $4.5 billion, it would smash the American record for most money ever paid for a sports team. 

The current record is held by the NBA's Brooklyn Nets, who sold for $2.35 billion in August 2019.
