Kakao reports two segments. Platform (~$3.07 billion (KRW 4.318 trillion), 53% of FY2025 revenue) includes Talk Biz, which sells Bizboard display ads, business message channels, gifting commissions, and emoticon subscriptions inside KakaoTalk; Portal Biz (Daum); and 'Platform Others' such as Kakao Mobility and Kakao Pay. Content (~$2.68 billion (KRW 3.781 trillion), 47%) includes Kakao Games, music (Melon and SM Entertainment), story (Piccoma and Kakao Webtoon), and media production. KakaoTalk keeps acquisition costs low because new services can be surfaced to tens of millions of existing users, while high-margin Talk Biz advertising carries most of the group's profit. By Q2 2026 Platform had grown to 59% of revenue.
