Mercedes team principal Toto Wolff is engaged in final negotiations to offload part of his shareholding in the Mercedes F1 outfit.
The deal estimates Mercedes at £4.6bn – a record for a Formula 1 squad – after McLaren was appraised at £3.5 billion in an adjustment to ownership structure last September.
The Austrian executive, who owns one-third of Mercedes F1, would sell a shareholding in the region of 5%.
The 53-year-old will remain as team principal and CEO if the sale goes through.
Shareholder Structure
The other shareholders in the team are Mercedes-Benz and chemicals giant Ineos Group, who each also own one-third of the enterprise.
An official representative said: "We are providing no official statement on the matter. The management structure of Mercedes F1 stays unaltered, and each shareholder are dedicated to continued achievements of Mercedes-Benz in F1."
Valuation Increase
The deal would represent a substantial rise in worth of the Mercedes team after Ineos bought its share for £208 million in 2022.
This surge demonstrates the growth in market values of Formula 1 outfits in the past few years due to the increasing appeal of the sport around the world.
This trend was evident with the box-office performance of the F1 movie featuring Hollywood star Brad Pitt, which was released in summer 2023 and has grossed over $630m (£458m) at the box office.
The film represents the actor's top-grossing movie and the most successful sports movie to date.
Current Performance
The Mercedes team are second in the constructors' championship, behind McLaren, with three races remaining in the current championship.
Mercedes' primary racer George Russell has won two of the 21 races so far and is fourth in the individual standings after McLaren drivers Lando Norris and Oscar Piastri, and Red Bull Racing's Max Verstappen.
Mercedes won a unprecedented eight straight constructors' championships and seven driver championships, six won by Lewis Hamilton and one by Nico Rosberg, between 2014 and 2021.
