Bang debuted as a composer while in college. He met
Park Jin-young in 1997, and the pair often partnered together as a songwriting duo. Bang co-founded
JYP Entertainment with Park, becoming a composer, arranger and producer at the company. One of their early successes was the first-generation group
g.o.d. Besides g.o.d, Bang has produced or composed for many other artists, including veterans
Im Chang-jung and
Park Ji-yoon, singer-actor
Rain, groups
Wonder Girls,
2AM, and
Teen Top, and R&B singer
Baek Ji-young. Nearly four years after co-founding JYP Entertainment, Bang left JYP and founded his own company,
Big Hit Entertainment, where he continued to write, compose and produce for its artists. Under the Big Hit label, he signed up
RM, at age 15, who would go on to lead the boy band
BTS. He co-wrote six songs for BTS in their 2016 album
Wings. Its success garnered Bang the Best Producer Award at the
Mnet Asian Music Awards and the Songwriter Award at the
Melon Music Awards that year. In June 2018, he was named one of
Variety's International Music Leaders due to BTS' achievements. In April 2019,
Bloomberg estimated Bang's worth to be about $770 million. The BigHit
initial public offering (IPO) filed in October 2020 was the largest seen in South Korea in three years and skyrocketed Bang's net worth to $2.8 billion, making him the only billionaire in South Korea's entertainment industry and the sixth-richest person in the country. The success of the IPO, together with the commercial success of BTS that year, Bang's steps into diversification with apps like
Weverse, and acquisitions of companies like
Source Music and
Pledis Entertainment among others, landed him on the 2020 edition of
Varietys
Variety500, an annual index of the 500 most influential business leaders in the global media industry. In June 2021,
Forbes Asia published its annual list of
Korea's 50 Richest People. One of only two newcomers to the ranking, Bang was listed as the 16th richest person in South Korea. On July 1, following an organizational restructuring,
Hybe announced Bang's resignation as CEO of the company to return his focus to music production. He was replaced by Park Ji-won, but retained his position as Chairman of the Board of Directors. According to the
Bloomberg Billionaires Index, Bang is worth an estimated $3.2 billion as of July 2021. Bang was featured on the cover of the April 2022 issue of
Time magazine, together with BTS, following the release of the outlet's annual list of the 100 Most Influential Companies in March. Later that month, he received an
honorary doctorate in Business from
Seoul National University—he is the first figure in the entertainment industry to be awarded such—in recognition of his "contribution to the development and innovation of the nation's cultural and entertainment industry" and for his "role in turning K-pop into a global pop music culture".
Fraud investigation In December 2024, South Korea's
Financial Supervisory Service (FSS) launched an investigation into allegations that, ahead of Hybe's 2020
IPO, Bang entered into profit-sharing agreements with private equity funds without proper public disclosure to the market. Hybe denied any legal violation, stating that "the shareholder agreement in question" had been reviewed by IPO underwriters during the listing process and deemed not mandatory for disclosure. On July 16, 2025, the
Financial Services Commission (FSC) formally referred Bang and three other executives to prosecutors on suspicion of unfair trading related to the IPO. A week later, on July 24, police raided Hybe's headquarters in Seoul as part of the investigation. Hybe stated it was fully cooperating with authorities and expressed its intent to prove compliance with all laws and regulations. In August 2025, Bang voluntarily returned to South Korea to cooperate with the investigation. On August 6, 2025, he sent a company-wide message to employees expressing regret over the concern caused, stating he had already offered a comprehensive explanation to the FSS, and stating that he was "temporarily putting aside urgent work and business meetings in order to prioritize cooperating with the authorities’ investigation process". He was set to be questioned on September 15, 2025. In December 2025, the
Seoul Southern District Court approved the
Seoul Metropolitan Police Agency's request in November to provisionally seize his shares in Hybe worth 156.8 billion won (approx. US$118 million). On December 18, 2025, it was announced that the FSS's special judicial police launched an investigation into Bang, along with carrying out raids on his home and offices. In April 2026, South Korean police sought an arrest warrant for Bang. == Philanthropy ==
