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.

@StevenK Biden as 46th implies Cleveland was both 22nd and 24th, which implies Trump could be both 45th and 48th or Biden could be both 46th and 48th.
@kolotom99 He's the new minority leader of the house. After the speaker fiasco, I think Jeffries came out looking really good. For 15 straight votes he had unanimous support among all democrats. I wouldn't be surprised if his new position springboards him into the public consciousness.
