Hybe, the entertainment group behind K-pop act BTS, is following a Seoul courtroom drama with more than passing interest. At the heart of the case is a question that could reshape how takeover battles are conducted across South Korea's capital markets: when does aggressive share buying during a merger contest cross the line into illegal market manipulation?
The dispute traces back to 2023, when Hybe and Kakao, one of South Korea's largest technology conglomerates, fought a bruising battle to acquire SM Entertainment, the country's storied K-pop label. Hybe opened proceedings by purchasing a stake held by SM's founder, Lee Soo-man. Kakao responded by launching a public tender offer, during which SM's share price surged sharply. Hybe eventually withdrew. Subsequent investigations by South Korean financial regulators gave rise to allegations that Kakao had artificially propped up SM's share price to frustrate Hybe's competing bid — allegations that led to criminal charges.
At the first-instance trial, Bae Jae-hyun, Kakao's head of investment, and several associates were convicted under Article 176 of the Capital Markets Act, which prohibits market-price manipulation. The defendants have appealed, arguing that their buying activity amounted to nothing more than legitimate participation in a competitive M&A process. Prosecutors counter that purchasing shares with the explicit aim of maintaining prices above a particular level is a textbook case of manipulation that undermines market fairness.
Legal observers regard the appeal as potentially landmark. "When large-scale buying in the course of an M&A transaction inevitably pushes up the share price, that alone is not unlawful," said one lawyer specialising in capital markets law. "The critical question is whether the intent and method of the buying satisfy the statutory definition of market manipulation." How the appeals court rules could set a precedent governing the conduct of future takeover contests throughout South Korea.
For Hybe, the outcome carries concrete financial implications rather than merely symbolic significance. A confirmed guilty verdict would amount to judicial acknowledgment that Kakao's unlawful conduct caused Hybe to lose the SM bid, potentially opening the door to a civil damages claim. An acquittal, by contrast, would leave Hybe's moral grievance intact but strip away any viable legal remedy.
Comparable cases overseas offer some context. The United States Securities and Exchange Commission has long treated proof of intent as central when evaluating alleged manipulation during M&A transactions. Britain's Financial Conduct Authority has similarly applied rigorous standards to share-price support operations conducted during tender-offer periods. South Korea's judiciary now faces pressure to articulate its own standard — one that will inevitably influence market practice for years to come.
Since its retreat from the SM contest, Hybe has pivoted towards expanding its own artist roster and acquiring international music labels. Yet the appeal's verdict will matter well beyond Hybe's own balance sheet. It represents a signal to the entire entertainment and broader M&A community about how robustly South Korea intends to police fair competition in its capital markets.
