The deal is finalised but remains under wraps for now—Cadillac is poised to join Formula 1 as the eleventh team in 2026.

According to anonymous industry insiders cited by the AP news agency, Liberty Media, which owns Formula 1, has chosen not to make the announcement during the high-profile Las Vegas GP.

Sky Italia reports that the formal announcement is expected to occur next week.

One condition for Cadillac's entry into F1 was reportedly the removal of the Andretti name, despite the team being headquartered at Andretti Global's newly established base in Silverstone.

In its first two years, Cadillac F1 will use Ferrari power units for 2026 and 2027, with General Motors (GM) set to produce its own engines beginning in 2028.

"The discussion is between FIA, the team, and FOM," Ferrari boss Frederic Vasseur commented in Las Vegas. "It's not our choice.

"But if it's good for the sport, good for the show, good for the business, and adds value on the sporting side, that we are all ok."

Sky Deutschland and Blick newspaper claim the car is being developed at Toyota's wind tunnel facility in Cologne.

McLaren CEO Zak Brown hinted that Cadillac's entry is a done deal. "We haven't been told officially, but we are involved with GM with our Indycar team. I've seen them here, and they seem to have big smiles on their faces," Brown remarked in Las Vegas.

"So I think an announcement is probably inevitable, and it would be great to have another manufacturer join our sport alongside Audi. GM has a great history in motorsports, so I think it's great—more competition. The fans will definitely be excited."

Cadillac is expected to pay a significant entry fee, estimated between $200 and $600 million, to offset the impact on the prize pool shared among the current ten teams.

Red Bull team principal Christian Horner acknowledged the financial implications, telling Kleine Zeitung: "I don't want the prize pot to be diluted as a result, but it's probably going to cost us all a little bit."
