Team Iron Man as viewers saw it in Captain America: Civil War is no more, as half the team is dead and the rest either switched sides or are no longer part of this universe - so, in reality, Team Cap won out in the end. Directed by Anthony and Joe Russo, Captain America: Civil War took concepts from the Civil War storyline from the comics and adapted them to the MCU, with the superhero roster at the time dividing in two teams: Team Captain America and Team Iron Man.
What fractured the Avengers in Civil War was a disagreement over international oversight of the team as well as the registration of superheroes with the Sokovia Accords - a name that derives from the Battle of Sokovia in Avengers: Age of Ultron. All of this was only made worse when the Winter Soldier was blamed for the attack on the U.N., not to mention the reveal that he was responsible for the death of Tony Stark’s parents. All differences were set aside, though, in Avengers: Endgame, where all heroes joined forces to fight against Thanos and his army, but in the post-Endgame world, what was known as Team Iron Man didn’t make it past the MCU's Phase 3.
Team Iron Man consisted of Iron Man, Black Widow, War Machine, Vision, Spider-Man, and Black Panther, while Team Captain America had Captain America, Falcon, Scarlet Witch, Bucky Barnes/Winter Soldier, Ant-Man, and Hawkeye. Vision died in Avengers: Infinity War (and is somehow coming back in Disney+’s WandaVision), Black Widow sacrificed herself in Avengers: Endgame to get the Soul Stone (and she switched sides before that), and Iron Man also died in Endgame in order to save the world. Furthermore, Black Panther switched sides at the end of Civil War and Spider-Man is no longer part of the MCU, which makes War Machine the only remaining member of the team who's even standing. So, yes, Team Iron Man is officially over.
As for Team Captain America, it’s not completely over but it has fewer members than it originally had. Captain America went back in time to live the life he always wanted, and Falcon and Winter Soldier are teaming up in the upcoming The Falcon and The Winter Soldier series - so they're still going strong. Wanda survived the battle in Endgame but Vision and her went on their own way after Civil War, and Hawkeye spent Infinity War under house arrest, and agreed to join the Avengers in their time heist, just like Ant-Man.
Team Iron Man had a more tragic fate than Team Captain America, but if it hadn’t been for Iron Man himself, the MCU couldn’t have regained its balance. With Don Cheadle’s contract reportedly over after Avengers: Endgame, War Machine’s future remains unknown – unless another character mentions his whereabouts at some point. Just like the Infinity Saga was over with Phase 3, so was Team Iron Man, but their sacrifices are the base for the future of the MCU.
