Toto Wolff is engaged in final negotiations to sell part of his shareholding in the Mercedes Formula 1 team.
The deal estimates Mercedes at £4.6 billion – an unprecedented figure for an F1 team – after the McLaren team was appraised at £3.5 billion in an adjustment to corporate structure last September.
Wolff, who owns a 33% stake of Mercedes F1, would sell a stake in the region of five percent.
Wolff, aged 53 would stay on as team principal and chief executive officer if the sale goes through.
The other shareholders in the team are Mercedes and chemicals giant Ineos Group, who both hold one-third of the enterprise.
An official representative said: "We are providing no comment on this. The governance of Mercedes F1 stays unchanged, and all three partners are fully committed to continued achievements of Mercedes-Benz in Formula One."
The deal signifies a substantial rise in value of Mercedes F1 since Ineos acquired its share for £208m in 2022.
This surge reflects the expansion in market values of F1 teams in the past few years due to the increasing appeal of Formula 1 around the world.
This was also seen in the box-office performance of the F1 movie featuring Hollywood star Brad Pitt, which was released last summer and earned more than $630m (£458m) at cinemas worldwide.
It is the actor's top-grossing film and the most successful sports movie ever released.
The Mercedes team are second in the team standings, trailing McLaren, with three races left in the current championship.
Their lead driver George Russell has secured victory in 2 of the 21 races so far and is in fourth place in the drivers' championship behind McLaren's Lando Norris and Oscar Piastri, and Red Bull Racing's Max Verstappen.
Mercedes secured a unprecedented eight consecutive constructors' championships and seven driver championships, six for Lewis Hamilton and one by Nico Rosberg, between 2014 and 2021.
