£2.5bn will be used to buy Chelsea shares.
The new owners of the club will invest £1.75 billion in the development of the infrastructure of the club, according to the press service of the team of the English Premier League (EPL).
The Bowley Consortium also co-owns the Los Angeles Dodgers of Major League Baseball and the Los Angeles Lakers of the National Basketball Association.
The last owner of Chelsea was Roman Abramovich.
The Russian businessman bought the London club in 2003.
Under Abramovich, Chelsea won the championship and the FA Cup five times, won the country's Super Cup three times.
Twice won the Champions League and the Europa League, and also won the UEFA Super Cup and the Club World Cup.
Abramovich is on the UK sanctions list.
On February 26, the businessman handed over the management of the club to the board of trustees of a charitable foundation, and on March 2 he announced that he was going to sell Chelsea.
Earlier, a representative of Abramovich denied rumors of an increase in the value of Chelsea.
