Anthropic's recent funding round of $13 billion has propelled its valuation to $183 billion, enabling the company to implement restrictions on AI access for entities over 50% owned by firms in unsupported regions, particularly affecting Chinese tech giants like Alibaba and Tencent. Despite potential revenue losses in the hundreds of millions, the policy reflects Anthropic's strategic shift towards governance based on ownership rather than geographical location, posing challenges for affected companies in the global market.
