For long the sticker money in CSGO has been a popularity contest for the teams and players. The players / Teams who are most popular are the ones who receive the biggest share of the sticker money. This might not always mean that the best team gets the highest money from the sticker money.
Being popular doesn't help so much (anymore). Most sold are the Legend/Challenger caps and they are evenly split among teams/players.

But this tweet by ChrisJ seems to set aside the rumor that CSGO Major is a popularity sticker right now. The most sold stickers are the Challenger / Legends sticker money and that is almost equally distributed between the teams. This ensures that the teams are financially well off and tare amply rewarded for making it to the Majors.
