Warning: Spoilers ahead for Ant-Man and the Wasp.
Ant-Man in the Wasp is a movie about a very complicated family growing bigger and overcoming its issues. And by the end of the film, most of these issues are resolved before it's all thrown for a spin in a similar fashion to the conclusion of Avengers: Infinity War. Let's break down where these threads end and what Ant-Man and the Wasp's ending means for the future of the Marvel Cinematic Universe.
The main plot of Ant-Man and the Wasp picks up roughly two years after the events of Ant-Man and during that time, Scott Lang (Paul Rudd) got caught up in the Captain America: Civil War conflict which resulted in a plea deal for him with the government for breaking laws set forth in the Sokovia Accords. Lang is under house arrest and just days away from completing his sentence. He's been out of touch with Hank Pym and Hope who are on the run from the government and at odds with Lang for betraying their trust, but he's mended his relationship with his ex-wife (Judy Greer) and spends weekends with his daughter, Cassie (Abby Ryder Fortson).

During this time, Hank (Michael Douglas) and Hope (Evangeline Lilly) have built a new lab and have been doing everything they must (including working with a dealer of illegal special tech) to find a way to re-enter the Quantum Realm and rescue Janet van Dyne (Michelle Pfeiffer). They believe she's alive after Scott was able to enter the Quantum Realm and return during the events of the first movie. You can already see the layers of the family theme at work here. Scott can soon leave his house and spend more time with his daughter, while Hope and Hank are trying to make their family whole by rescuing Janet. Scott still must also mend his relationship with Hank and Hope, however, to bridge that gap.
The extra layer here is the introduction of Dr. Bill Foster (Laurence Fishburne) and Ava (Hannah John-Kamen), two characters that have their histories intrinsically to Hank Pym's past. The pair are a family unit themselves with Foster having essentially adopted Ava after the fall of S.H.I.E.L.D. and Ava is the way she is because of her father having worked for (and been fired by) Hank in the past. Ava, and Foster to an extent, are the de facto antagonists of Ant-Man and the Wasp but are by no means "villains" or evil.
Playing with the theme of family, the film wraps up on a rather positive note. Scott Lang finishes his house arrest sentence and can spend more time with Cassie and his relationship with his ex-wife and her partner (Bobby Cannavale) is happy and healthy. Janet is rescued and now part of the core Ant-Man and the Wasp family, working alongside Hank, Hope, and Scott. And Bill Foster, who's been trying to save the life of Ava this whole time is working alongside them - and with Ava - to continue exploring the Quantum Realm and its energies which Ava needs to survive. Everyone is fine, their issues resolved, and they're all part of the same team.
And then the mid-credits scene happens and we learn that Janet, Hank, and Hope have been eradicated when Thanos snaps his fingers with the Infinity Gauntlet at the end of Avengers: Infinity War, explaining why only Ant-Man appears in the leaked Avengers 4 concept art.
