According to the official announcement from Sui Network, the Sui mainnet has resumed normal operation, and transaction processing and network activity have both returned to normal. The official disclosure states that the two network outages that occurred yesterday and the day before were related to an interaction issue between the "Address Balances" feature introduced in version 1.72 and the Gas billing logic. The Sui core team indicated that the fix deployed yesterday was only a temporary measure aimed at quickly restoring network operation, but this solution carried a known and low-probability risk of outage. Today, the network triggered a variant of the known issue, causing the mainnet to pause again. Currently, the validators have completed the deployment of a long-term fix, and the official claims that the known issues caused by the original vulnerability have been thoroughly resolved, with the network now operating normally. The Sui team stated that they will release a more detailed incident review report in the future, explaining the cause of the failure and the repair process.

The approval voting rate for the preliminary agreement on wages and collective bargaining for 2026 by the largest union of Samsung Group has sharply increased. As a result, expectations for the approval of the agreement are rising. However, due to the significant bonus gap between the semiconductor sector and the equipment experience sector, as well as between the memory and non-memory sectors, discussions about fairness are expected to continue.According to the union, as of 8:29 AM local time on the 25th (7:29 AM Beijing time), out of 57,291 eligible voters, 49,363 have voted on the approval of the preliminary agreement on wages and collective bargaining, resulting in a voting rate of 86.16%. This vote is the final step in determining whether to accept the preliminary agreement reached by both labor and management regarding wages and collective bargaining. The core of the agreement is to allocate 10.5% of the operating performance of the DS department as a special management performance bonus fund, to be paid in the form of treasury stock.Industry insiders believe that members of the DS department, who account for about 80% of all union members, are likely to push the agreement through. As long as a majority of eligible voters participate and a majority of those who vote are in favor, the vote will be finalized. Voting will end at 10 AM on the 27th.

OpenAI CEO Sam Altman stated in a speech to employees that even if the IPO filing is submitted soon, the company may not go public immediately, and the actual listing time will depend on market conditions and other factors. The goal is to go public as early as September, but the timeline remains flexible.Earlier reports indicated that OpenAI plans to submit a confidential IPO application to regulators soon, possibly as early as this Friday. Sources revealed that investment banks, including Goldman Sachs and Morgan Stanley, are assisting OpenAI in drafting the IPO prospectus.Earlier this week, OpenAI cleared a significant hurdle on the road to the IPO—OpenAI CEO Sam Altman won a legal dispute against competitor Musk. OpenAI still needs to overcome a series of other challenges, the most significant of which is market concern over whether it can generate enough revenue to support its massive data center expenditure commitments.

Nomura published a report indicating that AI-driven demand is growing exponentially, while memory supply is limited, suggesting that memory stocks are set for a valuation reassessment. The firm significantly raised the target prices for Samsung Electronics and SK Hynix, with Samsung's target price soaring from 340,000 KRW to 590,000 KRW, and SK Hynix's target price rising from 2,340,000 KRW to 4,000,000 KRW, both rated as "Buy." Nomura stated that as AI semiconductor demand shifts from training to inference workloads, memory demand is entering a period of exponential expansion.In contrast, the firm believes that industry supply growth during the same period may still be constrained to about 5 to 6 times (with a compound annual growth rate of about 30%), raising serious questions about whether the structural supply-demand imbalance can truly be resolved. The firm mentioned that currently, the industry is attempting to narrow this widening supply-demand gap through various software and architectural optimizations, but Nomura believes these solutions can only slow the growth rate rather than reverse the trend.

James Comer, the chairman of the U.S. House Oversight Committee and a Republican lawmaker, has written to OpenAI CEO Sam Altman, requesting information regarding potential conflicts of interest related to personal investments and OpenAI. The investigation focuses on Altman's extensive personal investment network. Since Altman does not hold equity in OpenAI, his estimated net worth of approximately $3.5 billion primarily comes from his personal investment portfolio, which includes companies like Helion, Stripe, and Reddit.According to a previous report by The Wall Street Journal, Altman had pushed for OpenAI to invest $500 million in the fusion company Helion, while Altman himself has invested at least $375 million in the company. Comer stated that this has raised concerns about whether Altman is using OpenAI to enhance the valuation of his personally held companies. Additionally, attorneys general from states such as Florida, Montana, Nebraska, Iowa, West Virginia, and Louisiana have also written to SEC Chairman Paul Atkins, requesting an investigation into whether Altman has engaged in "self-dealing" and serious conflicts of interest.Meanwhile, Altman is set to testify in court on Tuesday and Wednesday in the case where Musk is suing OpenAI. Musk accuses Altman and OpenAI co-founders of violating the original "non-profit" commitment by shifting OpenAI to a profit-making operation. Although the conflict of interest investigation and Musk's lawsuit are independent events, Altman's personal investment issues have been raised multiple times during the trial. OpenAI board chairman Bret Taylor defended Altman in court, stating that he has been "open and transparent" regarding personal investment matters.
