According to Caixin, the "Management Measures for Online Marketing of Financial Products" jointly issued by the central bank and eight ministries will officially take effect on September 30, 2026. The measures aim to clarify the boundaries between finance and technology, and do not completely prohibit the online promotion of financial products, but rather provide specific guidance and regulations for marketing activities. It is specified that marketing financial products through public accounts, live broadcasts, and short videos should be conducted on the self-operated platforms of financial institutions or on accounts legally established by financial institutions on third-party internet platforms.In addition, marketers must be employees of financial institutions, possess qualifications for engaging in related business, and obtain authorization and consent from financial institutions. This means that if Key Opinion Leaders (KOLs) want to promote financial products, they must be certified to do so.

Samsung Electronics' wafer foundry division has recently surpassed 50% in the allocation of production capacity for the sixth-generation high bandwidth memory HBM4 substrate chips in the 4-nanometer process. The industry states that this division will invest more than half of its 4-nanometer wafers into HBM4 substrate chip manufacturing in the second half of this year to expand supply to companies like NVIDIA, Broadcom, and AMD.Samsung initiated mass production and shipment of HBM4 in February this year and plans to increase supply starting from the third quarter, significantly increasing the related wafer input since mid-year. This chip is based on Samsung's wafer foundry 4-nanometer (SF4) process. As of last month, over 50% of its total 4-nanometer capacity has been allocated to HBM4 substrate chips. According to insiders, Samsung's 4-nanometer process is currently at full capacity, with HBM4 substrate chips accounting for about 50% to 60%, and this high proportion will be maintained in the second half of the year.Samsung's wafer foundry production lines at Pyeongtaek Plant 2 and Plant 3 are mass-producing processes ranging from 4 to 7 nanometers, with a monthly capacity of about 30,000 wafers for the 4-nanometer process. Based on this, the wafer input related to HBM4 substrate chips is estimated to be about 15,000 wafers per month. During the second quarter earnings call, Samsung stated that it expects HBM4 revenue to increase more than threefold quarter-over-quarter in the third quarter, with HBM4 revenue in the second half expected to exceed 60% of the company's overall HBM revenue.

According to Electronic News on September 3, Micron plans to double its high bandwidth memory (HBM) production capacity compared to last year, with a maximum addition of 60,000 wafers per month by the end of this year. Insiders say that Micron's HBM output was about 40,000 to 50,000 wafers per month last year, and it is expected to reach about 100,000 wafers per month by the end of the year, narrowing the gap with Samsung Electronics and SK Hynix.Micron is increasing procurement orders from multiple HBM equipment suppliers, with production bases mainly in Taiwan and Singapore, continuously introducing equipment. Currently, the output is mainly HBM3E 12-layer, with HBM4 12-layer accounting for about 20% to 30% at the beginning of this year, which may rise to as high as 50% by the end of the year. HBM4 12-layer will be used in NVIDIA's latest AI accelerator, Vera Rubin, and Micron has started mass production of this product since the second quarter of this year.Micron CEO Mehrotra stated in the Q3 earnings call for fiscal year 2026 in June this year that the ramp-up speed of HBM4 12-layer mass production is about twice that of HBM3E 12-layer, and cumulative revenue from HBM4 shipments has exceeded $1 billion. The industry believes that Samsung and SK Hynix each have HBM production capacities of about 150,000 to 200,000 wafers per month. Counterpoint data shows that in Q2 of this year, the global HBM market shares were SK Hynix 50%, Samsung 32%, and Micron 18%. Micron is also preparing related investments in Hiroshima, Japan.

OpenAI CEO Altman stated that the voluntary review conducted by the Trump administration on the company's upcoming Astra model is a "productive process," and he indicated that as artificial intelligence capabilities continue to improve, strengthening communication with government officials around the world will become increasingly important. The upcoming Astra model is the company's first to be rated with a "critical" cybersecurity capability level.OpenAI stated that such models require stricter safety measures during development and prior to release. The Trump administration has established a voluntary framework for reviewing certain advanced AI models before their release, which may include allowing government officials access to the model for up to 30 days. Altman confirmed that the Trump administration has reviewed Astra and noted that the process is voluntary in nature. He mentioned that as these models reach quite high levels of capability, close cooperation with security agencies in the U.S., the U.K., and other parts of the world will become increasingly important, and Astra is "an important step forward."

According to Bloomberg, UBS analysts expect that China's semiconductor manufacturing capabilities may struggle to make sufficient progress in the next decade to develop solutions that can truly replace ASML's cutting-edge EUV lithography technology. UBS analysts wrote in their report, "The stage they are currently at seems comparable to ASML's in 2004." Based on patent application activities, especially in the fields of light sources and laser subsystems, China's current technological maturity is roughly equivalent to ASML's level 15 years before it began mass production of EUV equipment.UBS also expects that China is likely to have the capability for mass production of immersion DUV lithography machines within the next two to five years. Although immersion DUV is not as advanced as EUV, it remains an indispensable tool in chip manufacturing. ASML's immersion DUV machines are priced at nearly $90 million, while EUV equipment costs over $200 million each. China is one of ASML's largest markets, but due to export restrictions, ASML is prohibited from selling EUV equipment to China. UBS pointed out that considering the yield and capacity gaps and regulatory restrictions, Chinese lithography equipment is unlikely to be applied overseas. An ASML spokesperson did not respond to requests for comment. The report is based on UBS analysts' predictive views, and actual progress will depend on industry dynamics.

According to the Ontology blog, its core development team discovered potential security vulnerabilities during routine security checks. Due to a high emphasis on the security and integrity of the mainnet, Ontology has immediately suspended block production on the Ontology mainnet to allow the technical team and validators to conduct a comprehensive security review of the network and related components. Ontology stated that no security incidents have been confirmed at this time, and there are no indications that user assets have been lost or stolen. ONT, ONG, and other on-chain assets are currently assessed to be unaffected; this suspension is a preventive security measure rather than a response to confirmed asset losses or ongoing attacks.During the review period, block production will remain suspended, and on-chain transactions cannot be processed. Users do not need to transfer or take any action regarding their ONT, ONG, and other on-chain assets, but should avoid conducting time-sensitive on-chain transactions until the network officially confirms its restoration. The duration of the suspension has not yet been determined, and the team will prioritize the comprehensiveness of the security review over speed; block production will not resume until the network has been thoroughly assessed and confirmed to be secure. The Ontology team is collaborating with validators and ecosystem partners to address this matter and will update progress through official channels, with a separate announcement to be made before and after the network restoration.

According to South Korean media Chosun Biz, SK Hynix's NAND is lagging in the transition of old process lines, making it difficult to narrow the efficiency gap. As of the second quarter of this year, its 176-layer products still account for about 50%, while Samsung has completed the transition mainly to 236 layers. Omdia data shows that Micron's 232-layer products account for 53%, and YMTC reaches 68%.During the rising cycle of NAND prices, companies with a higher proportion of advanced processes see better cost and profit improvements. SK Hynix (including Solidigm) saw its NAND revenue share drop from 21.4% in the fourth quarter of last year to 16.4% in the first quarter of this year, while YMTC increased from 11.5% to 16.2%. SK Hynix prioritizes equipment investment in DRAM and HBM, with NAND investments decreasing for three consecutive years, from $3.5 billion in 2023 to $2.9 billion in 2025, slowing down the transition. It is currently considering impairing old NAND assets to optimize costs.
