Realize THIS: If Kaido lost right now, it was literally because he CHOSE to not get out of the way and take the attack head on. That would be so lame!!!
Not only that, but yes, they need to be awakened. It makes no sense to the story if they are not awakened. They couldn’t have been using it, because Oda reveals through dialogue when they use awakening. They better get up or Wano goes down significantly in my arc rankings.
Kaido has been taking attacks head on for the entire Arc, he has suicidal tendencies this point makes no sense.
So yeah they are probably awakened and have been using it during their fights, because it makes NO sense for them not to.
Both recognized their opponents as strong they proceeded to use new unique abilities for me it's pretty obvious Bigger Mom was a awakened ability since we had a entire Arc with her where she never showed anything like it.
Kaido on the other hand either his magma Dragon is his Awakened form (that form makes absolute no sense lol) or the ones he started doing with Shuron Hakke, his drunken mode.
