The forward is one of the most exciting young prospects in world football and plans to represent the club he joined at the age of seven for many years to come by penning a new deal.
Speaking to CNN Sport, Yamal said: "I don't know when (the contract will be signed), but I'll believe it'll be soon.
"In the end, Barca is the club of my life. I hope to renew my contract with them and to be with them as long as possible.
"I want to play in the Spanish league, I want to play for Barca, and yes, I will renew my contract. I will."
Yamal exploded onto the global stage with his excellent performances during Spain's victorious Euro 2024 campaign and is aiming for more success at club level in 2025 under manager Hansi Flick.
He said: "It's true that Hansi is a different coach. The style of play is different. We've looked to adapt to what he's told us, and I think we're doing it well.
"In 2025, we'll give it our all to win trophies, starting with the Spanish Super Cup and hopefully, it will be the best year of our lives."
Barca are seeking to win back the La Liga title this season and Yamal is confident that the team can triumph in what looks set to be a close three-way battle with Real Madrid and Atletico Madrid.
Asked if the club will win the league, Yamal said: "Of course. No question.
"In the end, La Liga will be won against teams we've previously lost to. I think it's about focus. We've shown in the important moments that we are the best and we'll continue to do so."
