There are 3 possible outcome
Option 1, He is Alive and will be relevant.
That is what I
99.99% believe in. That is by far the most likely outcome in my eyes. Oda did not introduce him as luffy's rival for nothing unlike what many people are thinking. I 100% believe that 1079 will just end up making him stronger and more relevant in the future. Kid's whereabouts was updated every single arc in the new world. His first fight was him beating a yonko, we are in elbaf rn, jimbei asked the whales to look underwater and he didn't find anything, etc , etc. I have countless other reasons but we are already in elbaf anyways, only a matter of time till we see him.
Option 2, He is Dead.
I do not believe this for a second but it is still an outcome. Maybe Shanks really just killed him, maybe his role was really just to deliver poneglyphs to shanks and then die, maybe his last role as a character was really to be a shanks hype tool and be killed right at the beginning of the final saga.

Option 3 He is Alive and will not be relevant
This right here is
by far the dumbest one and I can't believe that many people buy into it. Him being dead and removed from the story makes sense unlike this. Oda will not go out of his way to make Kid lose like that, to then bring him back to the story for nothing, that does not make any sense at all(unless you believe oda just hates him, which is what people unironically believe). Plus Kid is a conqueror like him or not but in term of willpower, he is up there with Luffy there is just no way that he is going to give up at best he could have a moment like luffy calling himself weak and then strengthening his resolve (by the means of a character arc or someone to get his shit together like jimbei with luffy). Some people have a weird fixation on hating and downplaying him and thus not rating him fairly.
Oda making him survive his loss to Shanks just for him to not be relevant anymore when he had Shanks tell us not to underestimate how far the young guys crew is simply stupid. That is not gonna happen
