An ITV spokesman said in a statement: “There are no current plans for the next series of The X Factor at this stage.”
Previous judges on the programme include Sharon Osbourne, Louis Walsh and Nicole Scherzinger.
The programme first aired in 2004 and spawned spin-off shows X Factor: Celebrity and X Factor: The Band in 2019.
It was revealed in February last year that Cowell was resting the programme for 2020.
The X Factor has helped launch the careers of chart-topping artists including One Direction, Little Mix, Olly Murs and Leona Lewis.
Last month it was revealed Cowell will return to UK television to lead a panel of judges in a new musical gameshow for ITV titled Walk The Line.
