According to Xinhua News Agency, Iran's Fars News Agency cited sources as saying on the 19th that Iran has not held any direct talks with the U.S. after the U.S. violated the Iran-U.S. memorandum of understanding. A source close to the negotiation team told Fars that Iran's talks with the U.S. have been suspended following the U.S.'s violation of the memorandum. Separately, Iran's talks with Oman on the Strait of Hormuz are unrelated to the U.S. Meanwhile, in a CNN report on the 18th, U.S. President Donald Trump has ordered his negotiation team to cease contact with Iran. The report cited U.S. officials as saying that Trump is dissatisfied with Iran's unwillingness to meet his demands, and hopes to resume contacts after Iranian leaders demonstrate renewed willingness to strike the deal he is seeking.

According to a Bloomberg report, Chinese storage chip maker Yangtze Memory Technologies Co., Ltd. (YMTC) has completed its listing guidance, bringing it closer to a debut on the A-share market. Data from the China Securities Regulatory Commission (CSRC) website shows YMTC has finished pre-listing guidance and is deemed to meet the requirements of a listed company in terms of corporate governance structure, financial foundation, and internal control system. Market participants believe YMTC is expected to follow the capital market path of its competitor ChangXin Memory Technologies (CXMT), raising funds via IPO to expand production capacity and support China’s semiconductor industry self-reliance. Previously, CXMT completed the second-largest IPO in mainland China, raising around 66.6 billion yuan; its share price surged after listing, briefly making it one of China’s most valuable listed companies. Both YMTC and CXMT are key players in China’s semiconductor independent supply chain. Driven by AI demand, global storage chip supply tightness has drawn capital market attention to the two firms, with related chip industry chain stocks rising sharply recently. According to reports, YMTC’s NAND flash shipments in the second quarter of this year surpassed Japan’s Kioxia for the first time, becoming the world’s third-largest NAND flash supplier and further narrowing the market gap with Samsung Electronics and SK Hynix. However, news of YMTC’s IPO push has also sparked market liquidity concerns. Some investors argue that the listing of a large tech firm may siphon market funds, putting short-term pressure on tech stocks. On Wednesday, the Shanghai Stock Exchange STAR 50 Index fell 6.9%, marking its largest single-day drop in nearly a month.

CLSA released a research report stating that Zhipu AI (02513.HK)’s GLM-5.3 API is now open for access, delivering leading performance among domestic peers in complex coding and long-cycle agent tasks. Despite its smaller parameter scale, the model has achieved open-weight state-of-the-art (SOTA) results across multiple benchmarks, scoring 60 points on the Artificial Analysis Intelligence Index—matching Kimi 3 and outperforming Tongyi Qianwen 3.8 Max. The bank estimates that the GLM model’s revenue share on OpenRouter rose from 1% in January this year to 7% in July, surpassing DeepSeek’s 6% and Moonshot AI’s 3%. It added that DeepSeek’s recent price hikes signal healthy industry competition, while GLM 5.3 has regained its Pareto frontier status. Recent stock weakness may reflect an overreaction to Anthropic’s annual recurring revenue slowdown; the firm maintains an "Outperform" rating on Zhipu AI, with a target price of HK$2,061. (Jinshi)

The U.S. state of Florida has filed a lawsuit against OpenAI and its CEO Sam Altman, accusing the company’s generative AI products and large language models (LLMs) of constituting a legal "public nuisance." Reports indicate that several U.S. states are attempting to use the "public nuisance" legal framework to regulate AI firms, framing generative AI as "digital pollution sources" capable of causing social harm. The lawsuit alleges that AI chatbots can harm public mental health, provide unvetted advice, and pose public safety risks. Florida claims OpenAI’s rapid growth was built on deceptive practices and user exploitation, leading to widespread harm for state residents and disrupting social order. The state is seeking court-ordered restrictions and monetary damages. The case is currently regarded as a key example of U.S. regulators exploring the boundaries of AI liability. If the court upholds Florida’s "public nuisance" theory, it could prompt more states to take similar legal action against AI companies.
