Toto Wolff is in advanced talks to offload part of his shareholding in the Mercedes F1 outfit.
The deal values Mercedes at £4.6bn – an unprecedented figure for an F1 team – after McLaren was appraised at £3.5bn in a change of corporate structure last September.
The Austrian executive, who holds one-third of the Mercedes F1 operation, would sell a stake approximately five percent.
Wolff, aged 53 will remain as team boss and CEO should the deal proceed.
Ownership Structure
Remaining partners in Mercedes F1 are Mercedes-Benz and chemicals giant Ineos, who each also own one-third of the company.
An official representative said: "We are providing no comment on this. The governance of Mercedes F1 stays unaltered, and each shareholder are dedicated to continued achievements of the brand in F1."
Financial Growth
The deal would represent a substantial rise in worth of the Mercedes team after Ineos Group bought its share for £208m in 2022.
The rise reflects the expansion in market values of Formula 1 outfits in the past few years as a consequence of the increasing appeal of Formula 1 globally.
This was also seen in the box-office performance of the F1 movie starring Brad Pitt, which debuted last summer and earned over $630m (£458m) at cinemas worldwide.
The film represents the actor's top-grossing movie and the most successful sports film ever released.
Present Performance
Mercedes are second in the team standings, trailing McLaren Racing, with three Grands Prix left this season.
Mercedes' primary racer George Russell has won two of the 21 races so far and is in fourth place in the drivers' championship after McLaren's Lando Norris and Oscar Piastri, and Red Bull's Max Verstappen.
Mercedes secured a record eight consecutive constructors' championships and seven drivers' titles, six for Lewis Hamilton and one for Nico Rosberg, between 2014 to 2021.
