South Korea’s creator economy is maturing into a more concentrated business, with the top 10% of companies in the YouTube and digital media sector accounting for 76% of reported corporate revenue in 2025. For U.S. digital platforms, advertising buyers and investors watching the creator economy, the shift highlights both the commercial potential of professionalized content businesses and the widening gap between top earners and smaller operators.
Companies in South Korea’s one-person media industry reported combined revenue of 1.11 trillion won, equivalent to about $820 million, in 2025, according to data from the National Tax Service released on Oct. 20. The figures, obtained by a lawmaker, covered 2,024 corporations in industries related to individual media creation.
Of those businesses, 207 reported annual revenue of at least 1 billion won, or roughly $740,000, generating a combined 842.7 billion won, or about $623 million. That represented 76% of total reported corporate revenue. The other 1,817 companies accounted for just 270.7 billion won, or 24%.
The concentration has increased sharply as the industry expands. The number of creator-related companies reporting annual revenue of at least 1 billion won rose from 22 in 2021 to 207 in 2025, a 9.4-fold increase. Their combined revenue surged 13.3-fold, from 63.6 billion won to 842.7 billion won. Their share of total reported corporate revenue climbed from 60% to 76%.
The growth extends beyond large companies. The number of active individual business operators in creator-related industries rose to 36,604 in 2025 from 9,633 in 2021, a 3.8-fold increase. Active corporations grew 2.7-fold over the same period, reaching 3,182 from 1,167.
Individual operators whose primary business was in the sector also reported a sharp increase in gross business income. The total rose to 1.62 trillion won, or about $1.2 billion, for the 2024 tax year, from 796.7 billion won in 2021.
The figures offer a snapshot of a market increasingly shaped by the economics of scale. Larger creator businesses can build more diversified revenue streams through advertising, paid fan engagement and memberships, while smaller operators may have fewer ways to turn audiences into recurring income. For global platforms such as YouTube, the expansion of professional creator businesses can support advertising demand and paid services, although the concentration of revenue also raises questions about how widely those benefits are distributed.
Tax compliance is emerging as another issue as creators earn income through international platforms. South Korea’s National Tax Service said it does not directly collect income records from overseas video platforms. Instead, it uses foreign-currency receipt data associated with YouTube advertising, Super Chat, Super Thanks and channel memberships to assess earnings.
Authorities compare those records with value-added tax and income tax filings to identify businesses suspected of failing to report income or understating revenue.
Rep. Jung Tae-ho of the Democratic Party of Korea said the industry’s rapid growth had diversified both business structures and revenue models, requiring more sophisticated tax information gathering and oversight. He also called for more reliable access to information from overseas platforms and stronger verification procedures to ensure tax fairness.
For investors and companies exposed to the digital advertising market, South Korea’s creator economy presents a dual trend: a rapidly expanding commercial sector and a growing concentration of revenue among its largest players. The ability of regulators to track cross-border platform income could become an increasingly important factor as the industry matures.
