This market will resolve to the name of the person, who becomes the 48th President of the United States, whether as the result of the 2028 elections or otherwise (ie. Vice President takes the chair).

Please note, that the question asks about the 48th POTUS. 

If, for example, Ron de Santis wins the 2024 elections (47th President) and gets reelected, this market will resolve only after the 48th POTUS takes office.
