A Todd Boehly-led consortium completed their takeover of Chelsea on Monday.
The Premier League club announced on Saturday that the deal was officially set to go through at the start of this week.
Chelsea have now confirmed that they are under new ownership almost three months after Roman Abramovich decided to sell up.
An ownership group led by Los Angeles Dodgers part-owner Boehly, Clearlake Capital, Mark Walter and Hansjorg Wyss brokered a deal to buy the Blues for £4.25billion this month.
The Portuguese government last week approved the sale of the London club, a green light that was required as Abramovich has Portuguese citizenship.
The UK government declared that it was satisfied the deal would not benefit Abramovich, who was sanctioned due to his links to Russia's President Vladimir Putin following the invasion of Ukraine.

Russian oligarch Abramovich owned Chelsea for 19 years.
The 55-year-old stated when he put the Blues up for sale that the full amount that is paid to buy the club would go to a charitable foundation, with the money distributed to victims of the war in Ukraine.
Abramovich declared that the charitable foundation that is being established would be the legacy he and Chelsea had created together.
