Kim Sejeong Net Worth in 2026
Kim Sejeong’s net worth is not publicly confirmed, and there is no reliable financial disclosure establishing an exact figure. A cautious editorial estimate places her possible wealth in the range of $1 million to $5 million. This should be treated as an approximation rather than an independently verified valuation.
Her professional income has come from several areas of the entertainment industry. These include group activities with I.O.I and Gugudan, solo music releases, acting roles, television appearances, live performances, and commercial partnerships. Her work in popular dramas such as The Uncanny Counter and A Business Proposal helped expand her recognition beyond the music industry.
Online claims that she has a net worth of $8 million to $12 million, or that Forbes Korea and Celebrity Net Worth have confirmed those figures, should not be treated as established facts without reliable supporting documentation. South Korean entertainers’ personal assets, contracts, and earnings are generally not disclosed in enough detail to calculate an accurate personal net worth.
Personal Life & Career Beginnings
Kim Sejeong was born on August 28, 1996, in Gimje, North Jeolla Province, South Korea. She has spoken publicly about experiencing financial difficulties during her childhood. After her family moved to the Seoul area, she and her family stayed at her aunt’s home. Her mother worked several jobs, including delivering milk and tutoring, before becoming an accountant.
Her parents divorced when she was young. Sejeong has discussed how her mother’s hard work and encouragement influenced her decision to pursue a singing career. These experiences helped shape her determination to succeed in the entertainment industry.
Her major breakthrough came in 2016 through Mnet’s survival competition Produce 101. She finished in second place and became a member of I.O.I, the temporary girl group formed through the program. She subsequently joined Jellyfish Entertainment’s girl group Gugudan and also participated in its subgroup Gugudan SEMINA.
Alongside her group activities, Sejeong developed a solo music career. Her solo single “Flower Road” was released in 2016, followed by projects including Plant, I’m, and her 2023 full-length album Door. She began building her acting career with the 2017 television drama School 2017 and later appeared in The Uncanny Counter, A Business Proposal, Today’s Webtoon, and Brewing Love.
Assets & Business Ventures
Kim Sejeong keeps details about her personal assets and investments largely private. There is no dependable public documentation confirming that she purchased a luxury apartment in Seoul’s Gangnam district for $2.5 million in 2021. Claims about a specific Mercedes-Benz collection or other luxury vehicles should also be treated cautiously unless supported by reliable reporting.
Her publicly documented commercial work includes partnerships and advertising campaigns in fashion, beauty, entertainment, and consumer products. She was selected as a global ambassador for Longchamp and became a PlayStation advertising model in 2024. In March 2026, PharmaResearch announced her appointment as the global brand ambassador for REJURAN and REJURAN COSMETICS.
These partnerships demonstrate her commercial appeal, but endorsement appointments do not establish how much she was paid or whether she received ownership interests in those companies. There is also no reliable public evidence that she owns a café called “Sejeong’s Coffee” or holds a significant ownership stake in Jellyfish Entertainment. Her management representation transferred to BH Entertainment in April 2026 following the end of her exclusive contract with Jellyfish Entertainment.
Current Income Streams & Yearly Earnings in 2026
Kim Sejeong’s professional income is associated with her work as a singer, actress, and entertainer. Music-related earnings can include recorded music, streaming, songwriting or performance royalties where applicable, and live performances. Her solo releases and earlier group activities form part of her music career.
Acting is another important part of her professional work. Her roles in television productions, including The Uncanny Counter, A Business Proposal, Brewing Love, and the historical drama The Moon Flows in This River, have strengthened her profile as an actress. She has also appeared in variety and entertainment programs and performed in musical theater.
Brand partnerships provide another potential source of income. Her publicly reported commercial associations include Longchamp, PlayStation, and REJURAN. In 2026, she also held the global fan concert tour Tenth Letter, with performances in cities including Seoul, Taipei, Melbourne, Sydney, Manila, Hong Kong, Kuala Lumpur, and Yokohama.
Her exact annual earnings for 2026 have not been publicly disclosed. Figures claiming that she earns $50,000 to $100,000 per drama episode or $3 million to $5 million annually are not supported by reliable public financial records. Her actual income depends on private contracts, project schedules, agency arrangements, and other expenses that are not publicly available.
