Export Ban Escalates After Anthropic Refuses Government Demands

The Trump administration has blocked all foreign nationals from accessing Anthropic’s Fable 5 and Mythos 5 models globally, escalating from an initial targeted action against SK Telecom, South Korea’s largest carrier and a $100 million Anthropic investor since 2023.

The White House identified SK Telecom as a company suspected of having ties to China with access to Claude Mythos, triggering the initial request to revoke its access. Amazon researchers separately identified potential vulnerabilities in Fable 5 and reported them to the White House, which then broadened the ban to block all foreign nationals from both models.

Anthropic Rejects Government’s Fix-or-Pull Ultimatum

David Sacks, Co-Chair of the President’s Council of Advisers on Science and Technology (PCAST), disclosed that the Trump administration offered Anthropic a choice before issuing the export control directive: either fix the identified jailbreak in Fable 5 or voluntarily de-deploy the model. Dario Amodei refused both options.

Trump administration officials told WIRED that Anthropic must proactively test all frontier AI models to identify potential jailbreaks and report them to the government before any relaunch of Fable 5, and must eliminate all jailbreaks from Claude Fable 5 before relaunching.

Anthropic’s Seoul Confidence Signal

At a Seoul press conference on June 17–18, Chris Ciauri, Anthropic’s Managing Director of International, stated: “We are very confident that in the coming days, the models will become available again.”

This signal moved prediction markets sharply. Kalshi now prices a 57% chance Fable 5 returns before July 1, 67% before July 10, and 75% before July 17.

Refunds and Free-Trial Deadline

Anthropric issued refunds for subscribers who signed up between June 9–14 when Fable 5 was live, with a June 20, 2026 deadline for refund processing. The Fable 5 free-trial window for paid subscribers (Pro, Max, Team, and Enterprise) officially closes on June 22, 2026, after which subscription users need paid usage credits.

South Korea Business Momentum Amid Constraints

Despite the access restrictions, Anthropic signed a Memorandum of Understanding with South Korea’s Ministry of Science and ICT, committing both parties to collaborate on AI safety and cybersecurity, including evaluating model safety in the Korean language with the Korea AI Safety Institute.

Meanwhile, major South Korean enterprises continue deploying Claude products:

  • NAVER deployed Claude Code across its entire engineering organization with thousands of engineers now using Claude Code to diversify their coding tools and maximize coding productivity.
  • Samsung SDS is deploying Claude, including Claude Cowork and Claude Code, across Samsung Electronics for knowledge work, agentic workflows, and software development at scale.
  • LG CNS is deploying Claude to thousands of employees and plans to extend access across LG Group as a whole.
  • Hanwha Solutions is deploying Claude globally through AWS Bedrock with in-region data residency and security requirements.
  • Nexon, the global online game developer, has deployed Claude Code for its live-service game engineering, writing, reviewing, and shipping code for games played by millions globally.

Clause Code weekly active users in Korea grew 6x in four months. Large-business accounts above $100,000 in annualized revenue in Asia-Pacific grew 8x for Anthropic.
