The consortium including Lewis Hamilton has completed its record acquisition of the Denver Broncos NFL franchise.
The Walton-Penner group has taken over ownership of the franchise for an estimated $4.65billion [£3.84billion].
Hamilton's involvement was announced on August 2 and ahead of the beginning of the new NFL season, with pre-season games beginning this month.
The seven-time F1 champion's involvement comes after a failed bid, as part of a Sir Martin Broughton-led consortium, to acquire Chelsea Football Club earlier this year.
Despite agreeing to the sale from the Pat Bowlen Trust in June, at least a quarter of the 31 other owners needed to agree on the transaction, though it was confirmed that the vote had been unanimous.
Upon joining the group a statement said that Hamilton's "resilient spirit and standard of excellence will be an asset to the ownership group and the Broncos organization."
