The contracts of both Sainz and his team-mate Charles Leclerc are expiring at the end of 2024, with both drivers potentially becoming key players in the 2025 silly season.
But with Leclerc expecting to sign a fresh long-term deal at Ferrari soon, Sainz is also hoping to agree to new terms at Maranello this winter so he can start next year without any future talk distractions.
"My goal is to start 2024 knowing where I'm going to race in 2025," Sainz said at a sponsor event in Madrid.
"I wouldn't like to start the season without knowing my next destination.
"My priority is to stay at Ferrari for many more years.
"I'm very happy, both parties are very happy and the objective is to continue, but we have to agree and we have these three months until the next race to reach that agreement."

Sainz says he is "convinced" he will agree to new terms with Ferrari after feeling valued by incoming team boss Fred Vasseur, and hopes that will be reflected in a multi-year contract.
"Obviously I want to renew and I'd like to renew for more than one year, not just two," the 29-year-old Spaniard said.
"You know my intentions and honestly I feel perfectly valued by Fred and by the whole Ferrari family in general, I feel loved.
