Early Life & Family
Si Woo Kim was born on June 28, 1995, in Seoul, South Korea. His father, Kim Doo-young, introduced him to golf and helped shape his early development, while his mother supported a family move to Thailand so he could access better training and competition as a junior.
Rise to Fame
Kim turned professional at 17 and joined the Korean Tour in 2012. He earned his PGA Tour card soon after and announced himself with a win at the 2016 Wyndham Championship, before claiming The Players Championship in 2017 at age 21 — making him the youngest champion in the event’s history.
Career History
Kim has four PGA Tour victories to date: the Wyndham Championship (2016), The Players Championship (2017), The American Express (2021), and the Sony Open in Hawaii (2023). He has remained a consistent top-tier presence on tour through the mid-2020s, contending in marquee events including a strong showing at the 2026 American Express.
How They Built Their Wealth
The bulk of Kim’s wealth comes from PGA Tour prize money — his on-course earnings alone exceed $31 million, with total career earnings reported above $35 million. He has supplemented this with sponsorship and endorsement deals tied to golf equipment and apparel brands.
Personal Life
Kim married fellow professional golfer Ji Hyun Oh, a seven-time KLPGA tour winner, on December 18, 2022, in Seoul. The couple welcomed a son, Theo, in February 2024, after which Oh stepped back from professional competition to focus on family life.
With career earnings pushing past $35 million and continued competitiveness on the PGA Tour, Si Woo Kim’s net worth is estimated at $25 million to $30 million, a figure built almost entirely on tournament winnings and endorsements over a career that began in his teens.
