Following October 7 events, there are currently 101 Israeli hostages in Gaza strip.

This question resolve YES if at the end of 2025, the Wikipedia page of Israel Hamas Hostage Crisis, say that there is at least one Israeli hostage in Gaza that were abducted in oct 7 (not including the 4 abducted earlier).

Otherwise, this question will resolve as NO.

If there are overwelming evidence (according to global media) that all the hostages are dead, this will also resolve as no.
