Seoul in Play: Anthropic Talks Signal How the AI Cold War Wires Allied Tech Ecosystems
South Korea's engagement with Anthropic marks more than expansion—it's the latest node in a strategic alignment reshaping how Western AI infrastructure gets embedded in economies that supply both chips and compute.
South Korea’s science ministry met with Anthropic CEO Dario Amodei this week to discuss AI cooperation, continuing a courtship that began when the company announced Seoul office plans in October 2025.
The discussions covered Anthropic’s proposed Seoul office and the latest trends in the software-as-a-service industry, per The Korea Times. Anthropic’s run rate revenue in Asia-Pacific has grown over 10x in the past year, with Korean users ranking in the top five globally for Claude usage.
The engagement isn’t happening in a vacuum. South Korea is investing 8.6 trillion won ($5.77 billion) in 2026 across Semiconductors, AI, shipbuilding, energy and batteries—a 30 percent increase from 2025, according to The Korea Times. Samsung’s $230 billion AI infrastructure investment through 2030 forms one component of South Korea’s $735 billion sovereign AI initiative, launched after witnessing China’s AI advances and US-China technology decoupling, per analysis from Introl.
The Semiconductor Leverage Point
Seoul’s dual role creates strategic weight beyond market size. Samsung Electronics and SK Hynix hold 73% global market share for DRAM chips and 51% for NAND flash, accounting for 60.5% of the global memory semiconductor market. SK Hynix and Samsung supply high-bandwidth memory to Nvidia, Microsoft, Broadcom, and Tesla, forming an integral layer of the global AI stack, according to ITIF. In 2024, South Korea’s semiconductor exports reached $141.9 billion, accounting for 20.8% of total exports.
This creates what Carnegie Endowment researchers describe as mutual dependence: while siding with the United States on critical technologies leaves South Korea open to Chinese political pressure and industrial espionage, the ROK would only have marginal leverage against China without a security, economic, and technological alliance with the United States.
Anthropic’s existing Korean relationships illustrate the pattern. SK Telecom invested $100 million in Anthropic in August 2023 and entered a partnership to build a large language model customized for telcos, per SK Telecom. Korea’s largest telecommunications company chose Claude to create a custom AI customer service model that’s become a blueprint for the entire telco industry.
The Export Control Context
US restrictions on advanced chip exports to China have reshaped the strategic landscape. In 2024, BIS expanded controls to advanced packaging semiconductor manufacturing equipment, high-bandwidth memory, and DRAM, which extended controls to South Korean firms operating in China, per Congressional Research Service analysis. Samsung’s plant in Xi’an produces 40% of its NAND chips, while half of SK Hynix’s DRAM chips and upward of 30% of its NAND chips are produced at plants in Wuxi and Dalian.
The Trump administration has taken contradictory positions on chip exports to China. BIS now reviews export license applications for Nvidia H200 and AMD MI325X chips on a case-by-case basis, following Trump’s December 2025 announcement allowing H200 shipments to approved Chinese customers. This creates regulatory uncertainty for Korean chipmakers navigating US-China tensions while maintaining China production facilities.
While formally taking sides with the United States through the economic security alliance and the Chip 4 coalition, the South Korean government has allowed the private sector to explore options for muddle through, while taking assertive techno-statecraft measures including massive R&D investments and hefty tax incentives, according to analysis in Business and Politics.
The Pattern Across Asia-Pacific
Anthropic’s regional expansion reveals systematic alignment. Seoul comes on the heels of new offices in Tokyo and Bengaluru. CEO Dario Amodei traveled to Tokyo to meet Prime Minister Takaichi, address LDP Digitization Headquarters Committee members, meet customers and sign a Memorandum of Cooperation with the Japan AI Safety Institute, per Anthropic.
As competition for technological hegemony between the United States and China intensifies, Seoul and Singapore are laying the groundwork for strategic cooperation in high-tech fields such as AI, according to The Diplomat. The jointly hosted AI Connect Summit launched the Korea-Singapore AI Alliance to significantly expand cooperation in the AI field.
The commercial logic runs deeper than market access. The number of active weekly Claude Code users in Korea has grown 6x in the past four months, with more than a quarter of Claude Code users now coming from Asia-Pacific countries. A Korean software engineer currently ranks as the world’s top Claude Code user, exemplifying the depth of technical talent and adoption in the market.
What to Watch
Three vectors will determine whether Seoul-Anthropic engagement deepens into infrastructure-level integration or remains primarily commercial.
- Regulatory alignment: Whether South Korea adopts AI safety frameworks compatible with US and allied standards, particularly around model evaluation and deployment controls
- Cloud partnerships: If Anthropic announces Korean cloud service provider relationships or data residency commitments—signals of infrastructure stickiness beyond software licensing
- Research collaboration: Joint AI safety research or sovereign model development would indicate technology transfer beyond commercial deployment
- Chip export policy: How Seoul navigates pressure to restrict advanced memory exports to Chinese AI companies while maintaining China production capacity
Nvidia announced plans to expand South Korea’s AI infrastructure with over 250,000 GPUs across sovereign clouds and AI factories, with the Korean government investing in sovereign AI infrastructure with over 50,000 of the latest Nvidia GPUs across the National AI Computing Center and Korean cloud providers, per Nvidia. Where Anthropic’s models run on that infrastructure determines whether this is partnership or dependency.
The Seoul talks matter because they’re not really about Seoul. They’re about demonstrating that the Western AI stack—models, cloud, chips, safety frameworks—can be adopted by allied economies without forcing binary choices on China trade. The economic relationship between South Korea and China has shifted from being mutually complementary to increasingly competitive, creating structural challenges for bilateral cooperation, according to Brookings.
Every government that watches Korean chipmakers supply US AI infrastructure while maintaining Chinese fab capacity is calibrating its own position. The question isn’t whether Anthropic opens an office in Seoul. It’s whether Seoul becomes a proof point that allied tech ecosystems can be strategically wired—or a case study in how supply chain dependencies limit alignment.
