He did get a one way ticket to Adamantite. In the epilogue, it's implied that the Adventurer's Guild considered his feat to be one that a normal Orichalcum adventurer team could not accomplish. They probably thought it's only wise to just stick Momon and Nabe in Adamantite class after seeing the collateral damage the "fight" brought on.

Vol 06 probably pushed Momon's fame right up to legendary doorstep, leaving the normal Adamantite class coughing in the dust. I wouldn't be surprised if the Adventurer's Guild actually pushed to set up a new rank just for Momon in the later days.
