General Motors will reportedly pay a $450m (£358m) anti-dilution fee to join the F1 grid in 2026.

That is according to , who report that “senior sources in F1” have revealed that GM and the US group TWG Global will pay the huge sum to order to sec🌄ure their entry.

The reported figure is more than double the current $200m anti-dilution fee set out in F1’s exist𝄹ing rules.

F1 teams have been pushing for a major increase to the fund th🦩at any new entrant would have to pay as part of t🐲he new Concorde Agreement which needs to be finalised for 2026 onwards.

The anti-dilution fee is designed to offer compensation to the current teams when a new entrant joins the♍ grid and subsequently dilutes the prize money.

Around 63% of F1’s income☂ is paid out to the teams, but that will be split 11 ways instead of 10 once General Motors enters with its Cad🐲illac brand.

F1 announced on M🃏ondaꩵy that an agreement in principle had been reached for General Motors to enter the sport in 2026.

"With Formula 1's continued growth plans in the US, we have always believed that welcoming an impressive US brand like GM/Cadillac to the grid and GM as a future power unit supplier could bring additional value and interest to the sport,” said Greg Maffei, the outgoing president and CEO of ꧃F1 commercial rights holder Liberty Media.

"We credit the leadership of General Motors and their partners with significant progress in their readiness to enter 🐎Formula 1.

"We are excited to move forward with the application process for the GM/Cadillac team to enter the Ch🍬ampionship in 2026.”

It follows a p▨ush from the FIA a🔥nd its president Mohammed Ben Sulayem to expand the F1 grid.

"General Motors is a huge global brand and powerhouse in the OEM (original equipment manufacturer) world and is working with impr🍷essive partners,” 𒊎Ben Sulayem said.

"I am fully supportive of the efforts made by the FIA, Formula 1, GM and the team to maintain dialogue and work towards this outcome of an agreement in principle to progress this application to bring a GM/Cadillac branded team onto the grid for thꦡe 2026 FIA Formula One World Championship.

"All parties, including the FIA, will continue to work together to ensure the process progresses smoo♍thly."
