Ant-Man and the Wasp: Quantumania is the first first film in Phase 5 of the Marvel Cinematic Universe, and it is expected to kick off a new overarching Marvel Studios story that'll last across several movies, MCU TV shows, and years.
Jonathan Majors' Kang is believed to be the lynchpin of this new story arc (like Thanos in the first four Avengers films), leading ultimately to the fifth and sixth Avengers films - May 2, 2025's Avengers: Kang Dynasty and November 7, 2025's Avengers: Secret Wars.
So while Ant-Man and the Wasp: Quantumania is the third Ant-Man film, Quantumania could be the first movie in the next big thing for the MCU as a whole - for Kang, but also setting up some other big new things like some post-credits scenes, and possibly Cassie Lang graduating to becoming an Avenger.
You can prepare for this new arc of the MCU by going back and brushing up (or catching up) on the whole shebang with our MCU watch order.
So will there be an Ant-Man 4? If writer/director Peyton Reed has it his way, he'd like to do Ant-Man 4 - but as a prequel. Back in 2015, Reed proposed a Ant-Man prequel focused on a younger version of Hank Pym - and actor Michael Douglas said he'd be all for it.
