SEOUL, South Korea (AP) — Powered by strong support from avid fans, shares of South Korea’s Big Hit Entertainment, the company that manages global pop sensation BTS, soared in their trading debut Thursday in Seoul.

Big Hit’s solid debut after an IPO that netted more than $800 million was widely expected by analysts given the loyalty of the fan base to the seven-member boy band that has been dominating Billboard charts after gathering a huge following around the globe.

Despite the concert-killing COVID-19 pandemic, Big Hit has prospered thanks to huge demand for its online content, including livestreamed BTS concerts that reportedly attracted more than 1.7 million fans.

The company’s shares opened at 270,000 won ($236), about double their initial public offering price. They surged 30%, hitting the daily trading limit, before falling back and closing at 258,000 won ($225), bringing the company's valuation to 8.7 trillion won ($7.5 billion).

Big Hit has a tight grip over its revenue streams, with BTS merchandise and other products exclusively sold through its “Weverse” e-commerce platform.

Big Hit raised 926.6 billion won ($841 million) in what was South Korea’s largest IPO since 2017.

“The company has managed to grow beyond the traditional revenue sources of album sales and concerts and diversify its business through online channels,” wrote Ahn Jin-ah, an analyst from South Korea’s E-Best Investment and Securities, in a report that described Big Hit’s stock market entrance as a “drop of dynamite.”

BTS accounted for more than 80% of the company’s revenue during the first half of 2020, according to a separate report by Samsung Securities.

BTS launched in 2013 and has a legion of global supporters who call themselves the “Army.” It became the first K-pop act to top Billboard’s Hot 100 chart last month with their first all-English song “Dynamite.”

The band — consisting of J-Hope, RM, Suga, Jungkook, V, Jin and Jimin — has performed in sold-out arenas around the world and was even invited to speak at the U.N. General Assembly last month.

BTS has become a source of national pride, with some lawmakers even arguing that its members should be exempted from the 2-year military service that’s mandatory for most able-bodied males, saying that the singers have already done much for the country.

Unlike many other K-pop artists whose carefully cultivated images are shaped by their management agencies, BTS members actively engage with their fans through social media and often write their own lyrics. That personal touch is a huge part of their appeal, music experts say.

BTS fans who apparently follow everything and anything about the band naturally took an interest in Big Hit's stock market debut.

Sara Ali, a BTS fan from Sudan, said she had been talking with fellow Army members about Big Hit’s business prospects and was hoping to buy a few shares herself.

“I believe this is an excellent opportunity,” she said through a text message.

The company's shares began trading just days after Chinese nationalists erupted in anger at BTS after its leader RM thanked Korean War veterans for their sacrifices while receiving a reward for promoting U.S.-South Korea relations.

Chinese internet users and state media took RM’s comments as a slap at China, whose soldiers fought alongside North Korea against South Korea and U.S.-led allied forces during the 1950-53 war that was halted by an armistice but no peace treaty.

BTS has yet to respond to the comments.
