Marvel Rivals: Duel of Kings currently appears to be a one-shot print issue that collects Marvel Rivals Infinity Comic issues #25–#30, so the run itself ends at issue #30 in that storyline collection.

What that means

  • The print comic Marvel Rivals: Duel of Kings #1 is not a multi-issue miniseries; it’s a single issue collecting the existing arc.
  • The collected material is the Infinity Comic run #25–#30 , which is the clearest answer to where this current run ends.
  • The promo material around the issue focuses on Namor, Black Panther, and Wakanda’s Chronovium, but it does not indicate a later issue beyond that collected end point.

Quick note

If you meant the Marvel Rivals Infinity Comic sequence rather than the print one-shot, the current Duel of Kings story is the part that runs through #30.
