That is a popular one! But why do you think that?
Well, there are several clues throughout the books and show that suggest Bran may have a connection to the Night King. For example, in the scene where Bran is touched by the Night King, it appears as if he wargs into the Night King's body. Also, the Night King seems to have mystical powers that are similar to Bran's abilities as the Three-Eyed Raven.
