K-pop concert tickets selling out within seconds has become increasingly common, but industry observers say automated purchasing programs known as “macros” are now one of the biggest reasons behind the problem.
Macros are computer scripts designed to automatically refresh ticketing pages and complete login and payment steps faster than human users. Because they operate at high speed, they allow some buyers to secure large numbers of tickets almost instantly after sales open. Authorities in South Korea say these tools are frequently used in illegal ticket-scalping operations that later resell tickets at inflated prices.
The impact on fans has been significant. Even when tickets appear to sell out within seconds, many later reappear on secondary markets at much higher prices. In one recent case, a scalping group reportedly earned about 7.1 billion won (around $4.8 million) by bulk-purchasing K-pop concert tickets using macro programs and reselling them at marked-up prices.
Police investigations show that macro-based ticket hoarding is often organized rather than individual. Some groups reportedly coordinated through online chatrooms, sharing technical tools and resale strategies to secure large quantities of tickets across multiple concerts. Authorities say such operations can involve thousands of tickets and affect performances across the country.
The issue has raised growing concern among fans who struggle to obtain tickets at official prices. Some have described purchasing tickets through normal sales channels as “like winning the lottery,” highlighting how quickly seats disappear despite strong demand from genuine audiences.
South Korean law already prohibits the use of automated programs to purchase tickets for resale, and enforcement efforts have increased in recent years. Police have warned that people who rely on third-party “proxy ticketing” services that use macros may also risk fraud or identity theft, as many illegal sellers operate through unofficial channels.
Industry experts say solving the problem will likely require stronger monitoring systems from ticketing platforms alongside stricter legal enforcement. Until then, macro-driven purchases are expected to remain one of the biggest obstacles facing fans trying to attend K-pop concerts through official ticket sales.
