Rare breakthroughs by Rescene and Ateez underscore how difficult long-term survival has become Blackpink performs during the "Deadline" world tour in Tokyo, Japan, on Jan. 18. (YG Entertainment) Two K-pop acts have been making headlines this summer, and their stories could not be more different.Girl group Rescene finally topped a music chart with "Love Attack," a song that had gone largely unnoticed for two years. Ateez, a group long celebrated abroad but overlooked at home, cracked South Korea's own charts for the first time with its new single "Bad" — eight years into its career.Such reversals of fortune look glamorous from the outside. But they remain the exception, not the rule.Even what the K-pop industry calls a "small-label miracle" surfaces only occasionally. Kiss of Life, launched in 2023 by the little-known S2 Entertainment, broke into a Billboard sub-chart and won its first local music show trophy the following year with "Sticky."Yet for every such story, the odds of just being able to debut are shrinking. The number of trainees at Korean entertainment agencies fell 38.3 percent in just two years, from 1,895 in 2020 to 1,170 by the end of 2022, with the shortage particularly acute among male trainees.Even debuting under a major label no longer guarantees success: Only a handful of recent rookies from Hybe, SM Entertainment, JYP Entertainment and YG Entertainment have made their mark.Illit, under Hybe's Source Music, sold 200,000 copies of its debut album in two days; SM's Hearts2Hearts topped a music show just 16 days after debut and won a rookie award within four months; and Big Hit Music's Cortis debuted at No. 15 on the Billboard 200, the second-highest debut album ranking for a K-pop act excluding project groups.

The difference is that big agencies can afford to give a struggling act a second album; small ones rarely can.Behind these numbers lies an unforgiving financial structure. Debuting a single group can cost 3 billion to 5 billion won ($2.2 million to $3.6 million), with fourth- and fifth-generation groups often requiring more than 10 billion won to turn a profit.Recouping that investment can take three years or more, meaning agencies often have just two to three profitable years within a standard seven-year exclusive contract. In practice, a company's "investment" becomes the idols' debt. Earnings first go toward paying that back, and after members are "settled," profits are typically split evenly with the agency, then divided again among members.When that settlement never comes, idols can end up performing without pay for years. In March, boy group The Boyz filed an injunction against its agency One Hundred Label to suspend its exclusive contract over unpaid settlements; singers Lee Mu-jin, EXO-CBX, Bibi and Lee Seung-gi followed with contract termination notices, all citing billions of won in unpaid dues.Aware of this widening gap, the Ministry of Culture, Sports and Tourism last month selected 10 small and mid-sized agencies, including Rescene's label, for a new program supporting overseas expansion — offering up to 300 million won per group annually for up to three years.

A paper by Sungshin Women's University professor Kim Jung-sub, released on July 30, analyzed all 1,182 idol groups that have debuted in the 30 years since H.O.T. in 1996.It found the average group survives just 4.12 years — barely 59 percent of a standard seven-year contract — and that roughly 45 percent of all groups leave the market within their first three years. Just 1.61 percent ever became million-sellers. Yet Kim notes that idol groups' three-year survival rate of 55.03 percent actually exceeds the 41.5 percent survival rate of ordinary Korean small businesses over the same period — suggesting the industry's reputation for risk may be somewhat overstated.Rescene's comeback, Ateez's belated domestic breakthrough and Kiss of Life's rare rise are not simply strokes of luck. They are what a shrinking handful manage to pull off in an industry where neither a big label's backing nor a strong debut guarantees survival. Behind the sparkle of a comeback stage, every idol's ordinary day is still a fight to stay in the game. Cortis performs at Lollapalooza Chicago at Grant Park on Aug. 1. (Big Hit Music)
