My Spy made its U.S. premiere in June 2020 on Amazon Prime Video labeled as an Amazon Original. According to Slashfilm, STX Entertainment pushed My Spy's original theatrical release date of August 23, 2019, to March 2020 to avoid overlapping another Dave Bautista film and STX's family friendly Playmobil Movie. The March release was pushed back another month, to April, 2020, to take advantage of the Trolls World Tour release date that opened up when the Trolls sequel was moved to digital release because of the coronavirus pandemic. Ironically, that resulted in My Spy's own digital premiere when the health crisis shut down theaters across the U.S. According to Deadline, My Spy earned about $5 million in its brief international release.
