The Sweden striker is being linked with Barcelona and Arsenal this summer.
In an interview with Fotbollskanalen, Isak discussed the rumours and his future.
"I enjoy myself very, very well in Newcastle. I had my best season now in my career. That should not be underestimated. I really love everything about the club, the fans, the city," he says.
"I actually have no thoughts of a move or anything like that. I enjoy myself fantastically well and am very happy with my existence.
Newcastle may be forced to sell players this summer to balance the books. And it has been suggested Isak could be sacrificed.
"It is not something I speculate on. Within the team or the club there has been no talk or drama around it. I have not received information from the club that they would have to sell me," he added.
The Swede's contract with Newcastle runs until the summer of 2028.
