South Korea's Platform Law Could Strip $525B From U.S. Economy Over Next Decade, Model Finds
A Competere Foundation model estimates that South Korea's proposed Online Platform Fairness Act could cost U.S. states $525 billion in economic activity over the next decade, with California alone absorbing $123 billion in projected losses. The pending legislation, spearheaded by the Korea Fair Trade Commission and backed by President Lee Jae-myung, is drawing sharp criticism from U.S. lawmakers who argue that Seoul's regulatory posture is tilting against American companies.
A Competere Foundation model estimates that South Korea's proposed Online Platform Fairness Act could cost U.S. states $525 billion in economic activity over the next decade, with California alone absorbing $123 billion in projected losses. The pending legislation, spearheaded by the Korea Fair Trade Commission and backed by President Lee Jae-myung, is drawing sharp criticism from U.S. lawmakers who argue that Seoul's regulatory posture is tilting against American companies.
State-Level Exposure Mapped by the Model
The Competere Foundation's projections break the $525 billion figure across major U.S. states: Texas faces $48.7 billion in estimated losses, New York $33.9 billion, and Washington state $27.4 billion. The same research, cited in an April letter signed by 50 House members to ROK Ambassador Kyung-wha Kang, places combined damage to both U.S. and Korean economies at $1 trillion over ten years, with American households losing nearly $4,000 each. Shanker Singham, CEO of Competere Foundation, said Korea is already an "increasingly unfriendly place for U.S. companies to do business" and that looming regulations would worsen that environment further.
Congressional Alarm Over Regulatory Drift
Rep. Darrell Issa, R-Calif., pointed to South Korea's existing 20-year ban on Google Maps as evidence of a troubling pattern, telling Fox News Digital the country's trade commission "resembles the worst of Lina Khan's FTC." Former Utah Republican Rep. Chris Stewart framed the risk in strategic terms, arguing that every time Korean regulators constrain U.S. companies such as Coupang, Google, or Meta, Chinese firms gain market share in one of the world's key digital economies. Issa said in April that South Korean leadership is "closely aligned with China."
Coupang Fine Adds to Bilateral Friction
The tension has a recent flashpoint. In early June, South Korea fined Coupang, a U.S. technology company, roughly $410 million for a data breach — the largest such fine the country has issued. South Korea's science ministry attributed the breach to a Chinese national and former Coupang employee who stole data including information on South Korean citizens. The South Korean embassy told Semafor the investigation was "proportionate" and consistent with standards applied to Korean companies in comparable cases.
Policy Shift Behind the Legislation
The political backdrop sharpens the bilateral dimension. Conservative President Yoon Suk-yeol was impeached in December 2024 after imposing martial law; Lee Jae-myung, who narrowly lost to Yoon in 2022, won the presidency in 2025. The Democratic Party already held a commanding majority in the National Assembly, and South Korea is now operating under a full Democratic majority. Foreign policy analysts Nicholas Eberstadt and Lawrence Peck published a Wall Street Journal editorial in early June titled "South Korea Takes a Hard Left Turn Against America," alleging South Korean officials raided U.S. air force bases as part of the domestic Coupang investigation. The Online Platform Fairness Act remains pending in the National Assembly.
