No, Godzilla Vs. Kong Doesn't Have an End Credits Scene, and This Is Why - IGN
According to an interview at
Syfy Wire, director Adam Wingard has said that footage previously planned for a post-credits scene has instead been used elsewhere in the film.
“We actually shot a post-credits scene but then we ended up using it in the movie," Wingard told Syfy Wire. "[It was] one of those things where we shot it as one idea, and we got into editorial and realized 'we need a moment at a certain point in the movie,' [so] we ended up taking that footage and using it in a different context in the movie and it really, really worked for us."
