US Anthropic ban is best advert for Chinese AI

New US Commerce Department rules barring foreigners from Anthropic's flagship AI models have led to market shifts favoring Chinese firms like Zhipu AI, whose shares surged following an open-source release. Analysts suggest the restrictions may hurt Hong Kong's financial competitiveness while highlighting the limits of export controls on software.

Lead

A US Commerce Department directive ordering Anthropic to block foreign access to its newest AI models has triggered a market realignment that analysts say may benefit Chinese competitors. The restrictions, which took effect in June, have led to a surge in shares of Chinese AI firm Zhipu AI, whose smart assistant GLM-5.2 was released as open source, and raised concerns about the competitiveness of Hong Kong's financial sector.

The US Commerce Department ordered Anthropic to deny foreigners access to its Fable 5 and Mythos 5 models, citing national security concerns. Because Anthropic could not practically verify user nationalities in real time, it shut down both flagship models globally, locked out its non-American staff-teams-and downgraded affected subscribers to an older model, as reported by the South China Morning Post.

Coverage Comparison

Reports from the South China Morning Post describe the market impact and the regulatory context of the US restrictions. One analysis notes that Zhipu AI's shares, trading under Knowledge Atlas Technology in Hong Kong, surged 48 percent intraday on June 15 after the company announced the open-source release of its GLM-5.2 foundation model. The rally continued, with shares reaching an intraday high of HK$2,980 in the morning of June 22, briefly pushing market capitalisation past HK$1.2 trillion—a 25-fold appreciation compared to its January debut.

A separate report highlights the effect on Hong Kong's financial sector. Goldman Sachs and JPMorgan Chase stopped using Anthropic's models in Hong Kong, a decision attributed to strict interpretation of the company's terms of use, which reflect Washington's restrictions on China's access to advanced American AI models. The report quotes a warning that preventing access to the world's most advanced AI models may pose a threat to Hong Kong's revival as an international financial centre, particularly as AI adoption accelerates in other regions, including for coding tasks.

The Commerce Department's export control directive gave Anthropic little time to comply, according to the reports. The company supported Washington's export controls and lobbied for stricter cross-border limits—a position that analysts say has since trapped the firm as it navigates the regulatory framework it helped build.

Key Claims

Zhipu AI's shares surged by 48% after it announced the open-source release of its GLM-5.2 foundation model; the rally continued with an intraday high of HK$2,980, briefly pushing market capitalisation past HK$1.2 trillion, as reported by the South China Morning Post.
The US Commerce Department ordered Anthropic to restrict foreign access to its Fable 5 and Mythos 5 models; the company shut down both flagship models globally because it could not verify user nationalities in real time, according to the same report.
Goldman Sachs and JPMorgan Chase halted use of Anthropic's AI models in Hong Kong, based on Anthropic's terms of use reflecting US restrictions, as reported by the South China Morning Post.
Analysts cited in the reports suggest the restrictions could undermine Hong Kong's competitiveness as an international financial centre, given the rapid adoption of AI tools elsewhere.

Perspectives

US regulatory perspective: The Commerce Department's directive to restrict foreign access to Anthropic's Fable 5 and Mythos 5 models was issued on national security grounds, following what Washington described as a jailbreak security vulnerability. The order is part of broader export controls that have also restricted Nvidia's advanced silicon and expanded the US blacklist.

Chinese AI industry perspective: The market reaction suggests Chinese AI firms may benefit from the restrictions. Zhipu AI's stock surge followed its open-source release of GLM-5.2, and analysts note that if foreign users cannot access the most advanced American models, many may turn to capable, lower-cost alternatives from Chinese companies.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
