A controversy surrounding Anthropic, the company behind the Claude AI assistant, has now been linked to a major South Korean telecom company.

According to WIRED, a Korean telecom giant sits at the center of what is being called Anthropic's "Mythos" controversy. A report surfaced by Yahoo names that carrier as SK Telecom, identifying it as the Korean company tied to the dispute, which centers on export controls.

Export controls are government rules that restrict which technologies and products can be sold to which countries or companies, often on national security grounds. The naming of SK Telecom places one of South Korea's largest carriers squarely inside a debate over how advanced AI technology moves across borders.

The story also intersects with U.S. politics. According to Benzinga, President Trump said Anthropic was a national security threat "a week ago, maybe," before going on to credit the Claude maker for an act — a notably shifting characterization of the company in a short span of time.

Taken together, the sources describe a single thread: Anthropic, an AI developer whose work touches on sensitive export-control questions, is at the heart of a controversy that now has a named corporate participant in SK Telecom and has drawn comment from the highest level of the U.S. government.

Why it matters: As AI tools become strategically valuable, the question of who can access them — and how governments and companies police that access — is moving from a technical footnote to a front-page national security issue.
