Hybe:
Obviously, it's BTS, but because they're currently on hiatus, Seventeen will take the lead as they are going on tour and have massive album sales.
YG:
Blackpink, but this year, it's probably Treasure, as YG didn't have profits from their individual activities anymore.
JYP:
I'm not sure between Twice and Stray Kids. I still think it's Twice, honestly, but I don't know if Stray Kids have already surpassed them in becoming the main money-makers for the company.
SM:
Probably NCT Dream or Aespa? NCT seems to be the most successful active boy group for now. Yet, Aespa is doing really well in sales too.
