Meanwhile, the club exercised an option to extend midfielder Lewis Baker’s contract for another season.
Baker, who has been with Stoke since January 2022, spent the first half of this season on loan with Blackburn before returning to the Potteries at the start of the year.
Stoke sporting director Jonathan Walters said, external Baker, “has been an integral part of our side since he returned to the club in January” and had “played some of his best football for Stoke City” under boss Mark Robins, who recalled the player when he took over.
On the departing Thompson, Walters said the club were grateful to someone “who, beyond question, gave 100% on each of the 178 times he donned a Stoke City shirt” and called his contribution to the side “significant and valued”.
