What If Season 3 release schedule & episode details

A still from What If Season 3Disney+

This Christmas, the MCU’s multiversal TV show will come to an end – so, if you can’t wait for What If Season 3, here’s exactly what time you should tune into Disney Plus, the new season’s release schedule, and what to expect from the episodes.

After Avengers: Endgame, Marvel embraced (for better or worse) the concept of the multiverse; once upon a time, it was a concept about which we knew frighteningly little, and now one of the saga’s most important TV shows is about to conclude.

What If has a simple, tantalizing premise: instead of the canonical implications of everything that happens in the movies, it dips in and out of countless alternate timelines. For example, we’ve seen Marvel zombies, a harrowing fate for Doctor Strange, and a world where Ultron beat the Avengers.

It’s been a quiet year for the MCU (we’ve had Echo, Agatha All Along, and Deadpool & Wolverine), and before 2025’s big releases, What If is taking us into the New Year in style.

How many episodes are there?

Howard the Duck in What If Season 3Disney+

There are eight episodes in What If Season 3, which is notably different from the first two seasons.

It’s not a huge reduction, but Seasons 1 and 2 had nine episodes each, so it’s unclear why Season 3 is closing the series with eight episodes.

“We do get to push genre a little bit. I’m super excited about some of the ones that are coming up. There are a few that are just fantastic. I think everyone’s going to nerd out because we get to push. And one of them’s going to sell a lot of toys. I can say that. One of them for sure is going to sell a ton of toys,” he told Marvel.

“There’s one that revisits characters from a Season 1 episode, but I won’t say which. But there is one that there’s some continuation a little bit. And that one’s turning out to be quite hilarious and we do love it.”
