Netmarble has invested around $190 million in Big Hit, the label behind one of South Korea's most popular boy band.
The ₩201.4 billion ($189m) investment will buy a 25.71 per cent stake in Big Hit, making Netmarble the entertainment company's second largest shareholder.
Big Hit's main property is BTS, a hugely popular South Korean boy band. According to Forbes, Netmarble announced a new game based on the band, BTS World, in February.
However, its biggest deal to date arrived before the IPO, when it acquired Kabam's Vancouver studio in December 2016. Though official figures were not disclosed, the deal was thought to be worth in excess of $800 million.
