Verstappen has demonstrated scintilating form so far at the start of this season, and recorded his sixth win of his brief career so far on Sunday; producing an incredible drive to steal the win from Ferrari driver Leclerc in Austria.
When asked by Sky Sports F1 whether Verstappen is the type of driver who would interest Ferrari, boss Binotto said: "No certainly not. We've got two drivers, we've got two contracts in place and we are very happy.
"Next season, our line-up is fixed and there are no reasons why it should be changed. I think things are going well in that respect."
Verstappen has been linked with a move away from Red Bull - with many suggesting he needs to move elsewhere to further his career and potentially be a world champion one day.
Mercedes boss Toto Wolff had been speculated to be in constant contact with Verstappen, but the Silver Arrows' boss denied that earlier this season.
