KT Genie Music operates three business lines: a music business centered on the 'genie' digital streaming platform covering both music services and distribution; a book content business run through subsidiary KT Millie's Library's e-book subscription platform; and other businesses spanning concerts, merchandise (MD/goods), and IT development services.
As of Q1 2026, music accounted for the largest share of revenue at 65.2%, but book content contributed 70.6% of operating profit, reflecting growing reliance on the subsidiary for earnings.
The music business is pursuing B2B revenue growth through telecom-partnered services with KT and LG Uplus, and connected-car cooperation with Hyundai Motor Group.
Major shareholders include KT Studio Genie (35.97%), CJ ENM (15.35%), and LG Uplus (9.99%), forming a structure that links the KT group and CJ content value chains.
In the domestic music distribution market, Kakao Entertainment's Melon retains the lead while global platforms such as YouTube Music and Spotify have pushed KT Genie Music's monthly active user ranking down to around fourth place.
KT Millie's Library, which runs the book content business, provides e-book subscriptions across B2C, B2B, and B2B2C channels and expanded into web novels and webtoons in 2025.
Other businesses—concert planning and ticketing, merchandise sales, and the online concert platform 'STAYG'—have actually seen revenue decline over the past three years.
The success of the diversification strategy hinges on how much the subsidiary and new businesses can offset structural stagnation in the core music business.
