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

Th💞at 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 secure their entry.

The reported figure is more than double the current $200m anti-dilutioꦇn fee set out in F1’s existing rules.

F1 teams have been pushing for a major 🌸increase to the fund that any new entrant would have to pay as part of the new Concorde Agreement which needs to be fina🔯lised 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 th🔯e teams, but that will be split 11 ways instead of 10 once General Motors enters with its Cadillaܫc brand.

🐲F1 announced on Monday that an agreement in pಌrinciple 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/Cadill🔥ac 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 rig𒐪hts holder Liberty Media.

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

"We𝐆 are excited to move forward with the application process for the GM/Cadillac tওeam to enter the Championship in 2026.”

It follows a push from the FIA anﷺd 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 impressive partners,” Ben Sulayem said.

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

"All parties, including the FIA, will continue to work toget𓄧her to ensure the process progress♔es smoothly."
