Under Boehly and Clearlake the six-time English champion has spent well in excess of $1 billion on transfers, including British record fess for Enzo Fernandez and Moises Caicedo.
Joao Pedro’s arrival comes as Chelsea prepares for a return to the Champions League after a two-year absence.
Under coach Enzo Maresca, the London club finished fourth in the Premier League last season, its highest place since Boehly and Clearlake bought out former owner Roman Abramovich, and also won the UEFA Conference League.
Chelsea can add to that at the Club World Cup, but the expectation next season will be to challenge for a first Premier League title under its American owners.
The 23-year-old Joao Pedro hit 10 goals in 32 appearances for Brighton last season and scored 30 across two years with the club.
He is the latest player to leave Brighton for Chelsea in a big-money move in recent years after deals for Marc Cucurella, Robert Sanchez and Caicedo.
The move also represents a sizeable profit for Brighton after signing Joao Pedro from Watford for 30 million pounds ($41 million) in 2023.
