ASAPAfter the Block, Anthropic Opens a Seoul Office — Global AI Converges on Korea
Just a month after rattling Korea by blocking Fable 5, Anthropic has returned with the opposite move. On June 17, 2026, it officially launched its Seoul office, and on the 18th it signed a memorandum of understanding (MoU) with the Ministry of Science and ICT to cooperate on AI safety and cybersecurity. With Anthropic now setting up a base after OpenAI established a Korean entity and Mistral AI began hiring Seoul-based staff, the center of gravity for global generative-AI companies is tilting toward Korea. This article lays out what happened, why Korea, and what we should watch closely.
What Happened
Anthropic officially launched its Seoul office on June 17, having earlier appointed Choi Ki-young as its Korea country head last month to prepare for the move. Then, on June 18, it signed a memorandum of understanding with the Ministry of Science and ICT to cooperate on securing AI safety and on cybersecurity.
The Seoul office is reported to be Anthropic's fourth global base. It's a signal that the company intends to go beyond selling models and put down roots in the Korean market by working directly with the government and businesses.
Why Korea, Why Now
The trend of global AI companies flocking to Korea is unmistakable: OpenAI set up a Korean entity, France's Mistral AI is hiring Seoul-based staff, and now Anthropic has established a base of its own. In just one year, major companies have set up bases in Seoul one after another.
Behind this lies Korea's competitive edge in semiconductors and infrastructure and its fast-adopting AI market. With strong demand for data centers and cloud, and rapid uptake across business and the public sector, Korea is seen as highly attractive as both a testbed and a market.
A Curious Contrast With the Fable 5 Block
Only a short while ago, Anthropic fully cut off Korean access to Fable 5 and Mythos 5 under U.S. export controls, sparking an "AI sovereignty" debate. That the same company opened a Seoul office and signed a safety agreement with the government in under a month is symbolic.
It's a two-sided picture: blocking access to the latest models on one hand, and establishing a base to cooperate on the other. It means that global AI's "control" and "expansion" are both aimed at Korea at the same time.
What Changes
On the positive side, this is an opportunity for Korean developers and companies. When a local base like Anthropic's takes shape, support, cooperation, and adoption all speed up, and joint work in the areas of safety and security can be expected as well. The opening of a government channel, as with the MoU with the Ministry of Science and ICT, fits the same picture.
A government-level cooperation channel opening — as with the MoU with the Ministry of Science and ICT — also matters. AI safety and security are the foundation of industry trust, so there's room for policy and technology to be developed in tandem.
What to Watch Closely
A local base doesn't automatically make a company "on your side." As the Fable 5 case shows, access to the latest models can be swayed by the home country's policy at any time, so even with bases being courted, "domestic alternatives and homegrown capabilities" remain necessary.
In the end, the key is balance. The strategy must combine making use of global companies' investment in Korea while spreading risk so that critical work isn't locked into a single foreign model.
