Ordinary South Koreans rushed to pour more than $50 billion into the initial public offering for the management agency of K-pop sensation BTS, sale organisers said after it closed Tuesday.

The trailblazing septet cemented their prominence in the world’s biggest music market in August, when their all-English track “Dynamite” debuted at number one on the US Billboard Hot 100.

They are credited with generating billions for the South Korean economy, and the flotation of their label Big Hit Entertainment will make its founder a billionaire — while adding millions to each BTS member’s net worth.
