According to Jin10, OpenAI Codex product lead Tibo said the team has identified and fixed multiple defects in Astra and will carry out a reset before local midnight today, which is noon Beijing time. Tibo said the team confirmed and fixed several issues after working with some users, including abnormal triggering of skills written for earlier models, an optional context-management experiment that could cause early stopping or replies to old messages and has now been disabled, and misconfigured engines that have been removed after causing measurable quality declines in tail traffic. The team also made smaller improvements and said the overall experience should improve noticeably, including more consistent execution, better tracking of users' latest messages, and more thorough checks of results as work progresses.

A cluster of 19 linked Polymarket accounts placed concentrated bets over the past few months on earnings reports from publicly listed companies audited by KPMG, including Wells Fargo, Home Depot, DoorDash, and General Mills. According to Odaily, the accounts made 42 trades, won 41 of them, and generated about $22,000 in profit. Funds reportedly moved among the 19 accounts, suggesting they may have been controlled by the same person or team. U.S. law enforcement is investigating a KPMG employee suspected of using Polymarket for insider trading after betting on whether quarterly results at listed companies would beat market expectations. It is not yet clear whether the account cluster is linked to the employee, and the analysis does not by itself prove insider trading. KPMG said it has a zero-tolerance policy toward trading on nonpublic client information and has strengthened related monitoring.

CATL said on September 11 that it bought back 604,300 A-share shares through a centralized bidding process on the Shenzhen Stock Exchange for about 200 million yuan, marking the first execution of its 200 billion yuan to 400 billion yuan repurchase plan, according to Jiemian News. The company said the shares will be cancelled and the registered capital reduced, with the buyback funded by its own or self-raised cash and carried out within 12 months after shareholder approval. The 400 billion yuan ceiling is the largest single buyback amount ever announced in the A-share market. CATL said the first repurchase was done at 330.15 yuan to 331.61 yuan per share, below the plan's 573 yuan-per-share cap. The company also said the move reflects confidence in its long-term outlook amid stock-price volatility and concerns about valuation, while its earlier buybacks were mainly used for equity incentives or employee shareholding plans. CATL's shares closed at 330.51 yuan on September 11, down nearly 30% from this year's intraday high of 468.75 yuan in May. Jiemian News reported that investors are watching whether automakers accelerate efforts to reduce reliance on CATL, after Li Auto said on September 7 that all of its models would use self-developed batteries and Xiaomi Auto named CALB and Sunwoda Power as strategic battery partners. Despite the share-price decline, CATL reported first-half revenue of 276.917 billion yuan, up 54.8%, and net profit of 43.284 billion yuan, up 41.98%.

AI remains one of the most active areas for early-stage investment, but investors said their criteria are becoming more specific as the technology evolves and the market changes. At a Sept. 11 investor discussion at the 2026 Inclusion·Bund Summit, five investors from ZhenFund, FreesFund, BAI Capital, Granite Asia and Jiuhe Venture Capital discussed how they assess AI across infrastructure, models and applications, and how they view valuation and bubble concerns, according to Jiemian News. BAI Capital AI investment head Feng Tian said the firm is pursuing both models and infrastructure as well as applications, arguing that current model capability still largely determines product capability and that productization has not yet reached the stage to support large-scale deployment. ZhenFund investment director Zhao Fuheng said investors are still focused on frontier technology and foundation models, while CICC? Wait, no.

U.S. President Donald Trump said on September 11 that if Republicans retain control of Congress in the November midterm elections, he will give every U.S. adult $5,000, according to Jiemian News. Trump said the payment would be called a “Trump dividend,” likening it to a listed company’s shareholder payout, and said it would have to be spent inside the United States. U.S. Vice President JD Vance said the money would come from tariff revenue. The report said the U.S. has about 270 million adults, meaning the pledge would cost roughly $1.35 trillion if carried out. Citing the Financial Times, China News Service said bond markets are increasingly worried about high U.S. government spending, while Americans are also frustrated by the Trump administration’s failure to curb inflation and the negative impact of the U.S.-Iran conflict. The analysis added that even if Republicans keep a congressional majority, winning approval for such a large payment would likely face major obstacles, as many Republicans are cautious about the plan.
