An official release date for What If...? hasn't yet been set, but a new report from IGN suggests it will arrive on Disney+ in August. The outlet was also able to confirm the release window with Disney, though an exact date in August wasn't reported. With its first season consisting of 10 episodes, the show has already been renewed for a second season.
Marvel moving the MCU to the small screen with exclusive shows on Disney+ has proven to be very successful.
