Ten million tickets and what Korean baseball became

In 2024 the KBO League sold more than ten million tickets across its 720-game regular season, a threshold Korean professional baseball had been approaching since the 1980s and had never crossed. The previous record, set in 2017, was roughly 8.4 million; attendance had drifted downward for several seasons before the pandemic and had to be rebuilt from near zero afterwards. Ten teams playing 144 games each in stadiums that mostly seat between twelve and twenty-five thousand produced an average gate above nine tenths of capacity for much of the season. For a country of fifty-one million with a crowded entertainment market, that is an unusual concentration of attention on one sport.

The composition of the crowd is the more interesting fact. Ticketing platforms and club membership data through the 2023 and 2024 seasons consistently showed women in their twenties as the single largest identifiable buying group, a reversal of the sport’s traditional demographic. The shift was not the product of a marketing plan so much as of what the ballpark had become: an eight-hour outing with food, merchandise, choreography and a great deal of downtime, packaged for photographs and shared as such. Clubs responded downstream — uniform lines cut for a different body and budget, collaborations with cosmetics and fashion brands, seating tiers sold on comfort rather than sightlines.

Cheering culture is the product being sold at least as much as the baseball. Each club retains a professional cheer leader and a squad, each batter has a personal song, and the songs change with the roster; supporters learn them the way they learn pop choruses, because they largely are pop choruses with substituted lyrics. This is a genuine competitive advantage over sports that expect quiet attention, and it is exportable in a way the game itself is not — clips of a synchronized third-base stand travel further than highlights of the pitching.

None of this has made the clubs into businesses. Nine of the ten franchises are owned by large corporate groups, and the tenth operates on sold naming rights, which is a variation on the same dependence. Stadiums are municipally owned and leased, so the clubs capture only part of the venue economics that sustain teams elsewhere. Annual operating budgets in the range of three to five hundred billion won across the league are met substantially by parent-company transfers booked as advertising expenditure, and gate revenue, merchandise and concessions cover a minority of costs at most clubs. The centrally negotiated media package — digital rights for the 2024 through 2026 seasons went to a domestic streaming platform for a reported 135 billion won in total — is meaningful money by Korean sports standards and still modest against the wage bill of ten rosters.

The record year therefore proves less about the industry than it appears to. A boom driven by discretionary leisure spending among young adults is a boom exposed to that spending, and Korean household budgets in the mid-2020s have been squeezed by debt service and by prices in exactly the categories a ballpark sells. What the attendance figure does establish is that demand for cheap, repeatable, in-person social occasions is larger than the sports market had assumed. A ticket in the outfield costs less than a concert, less than a theme park, and can be bought seventy times a season within an hour of most of the population.

That is the durable finding. Korean leisure spending has been moving away from one-off spectacles toward recurring, low-cost, sociable outings, and baseball happened to be the incumbent institution positioned to absorb it. Whether the clubs convert a decade of that into businesses that stand without their parents is a separate question, and 2024 did not answer it.
