Toto Wolff is in advanced talks to offload a portion of his shareholding in the Mercedes Formula 1 team.
The deal estimates Mercedes at £4.6 billion – a record for an F1 team – following the McLaren team was appraised at £3.5 billion in a change of corporate structure in September.
Wolff, who holds one-third of the Mercedes F1 operation, plans to divest a shareholding approximately 5%.
Wolff, aged 53 will remain as team principal and chief executive officer should the deal proceed.
Remaining partners in the team are Mercedes and industrial group Ineos, who both hold a third of the company.
A Mercedes spokesperson said: "We are providing no comment on this. The management structure of Mercedes F1 stays unaltered, and each shareholder are dedicated to the ongoing success of Mercedes-Benz in F1."
This arrangement would represent a significant increase in worth of Mercedes F1 after Ineos Group bought its share for £208m in 2022.
The rise demonstrates the expansion in valuations of Formula 1 outfits recently due to the growing popularity of the sport globally.
This was also seen in the box-office performance of the F1 movie featuring Brad Pitt, which was released last summer and has grossed over $630m (£458m) at the box office.
It is the actor's top-grossing movie and the highest-earning sports film to date.
Mercedes are second in the team standings, trailing McLaren, with three races left this season.
Their lead driver George Russell has won 2 of the 21 races so far and is fourth in the drivers' championship behind McLaren's Lando Norris and Oscar Piastri, and Red Bull's Max Verstappen.
Mercedes secured a unprecedented eight consecutive constructors' championships and seven drivers' titles, six won by Lewis Hamilton and one for Nico Rosberg, between 2014 to 2021.
