Vettel, who sits 10th in the drivers’ standings going into the British Grand Prix, will leave Ferrari at the end of the current campaign.
Ferrari opted not to renew his contract earlier this year and promptly announced McLaren’s Carlos Sainz will replace him.
Vettel has been lined up for a drive at Racing Point, who will be rebranded as Aston Martin ahead of next season.
