Godzilla vs. Kong cemented Kong's new king status in place! One of the biggest aspects of Kong's introduction to the MonsterVerse with Kong: Skull Island is that it was not being referred to as "King Kong" as many had expected. While there are likely a ton of rights issues tangling that name for the MonsterVerse, Godzilla vs. Kong decided to cement Kong's true crown in a different kind of way. As fans had seen in the climactic film, Kong goes from literal fish out of water to a Titan that can stand toe to toe with the King of the Monsters.
Godzilla vs. Kong does indeed confirm a "King Kong" type of designation for the MonsterVerse, but it's in a much different way than you would expect. Rather than defeating Godzilla and taking the title by force, instead Kong has gone on to reign over his own domain. Introducing the Hollow Earth to the MonsterVerse in full at last with this film, Kong is able to take his seat on a literal throne at one point in the film.
In Godzilla vs. Kong, the people working for Apex help Kong get into the Hollow Earth. Kong's happy to go because it's a chance at finding more family, but instead the giant ape finds history. Through his journey in the Hollow Earth Kong comes across a massive room in the center of a huge stone structure left by his ancestors. In this room are molds for his hand, and a giant radioactive axe that unlocks other parts of the chamber.
With giant stone ape structures and the architecture surrounding a giant, built-in stone throne, this suggests that Kong's species had been ruling the Hollow Earth while fighting against Godzilla on the surface world. Godzilla had its own pocket of Hollow Earth seen in the previous movie, but this sequence implies that the Kongs had their own territory. Thus, Kong gets to be king again. It might not have come as a result of a major victory, but it still makes its mark.
