According to monitoring by Beating, companies like Nvidia, Microsoft, and Meta have jointly expanded the open letter titled "Open Weights and U.S. AI Leadership." The number of signatories has increased from the initial 25 to 77. SpaceX has garnered the most attention. Previously, Elon Musk only retweeted Jensen Huang's post on X, stating, "Fully support, Jensen is right." At that time, the company did not sign, but now SpaceX has officially appeared on the list. The letter urges the U.S. government not to impose premature restrictions on downloadable and self-deployable open weight models and to differentiate between normal distillation and illegal extraction. Anthropic has still not signed.

On July 27, Bank of America securities technical analyst Paul Ciana released a report stating that historical data shows that the period from August to October is typically the weakest three-month rolling cycle for the S&P 500 index, and US stocks may face their toughest phase this year. The report noted that since 1928, the average return of the S&P 500 during this period has been close to zero (-0.02%), with only 55% of the years seeing gains. It is also the phase with the largest average drawdown among all rolling three-month periods, averaging a decline of 7.35%. Ciana indicated that seasonal weakness does not imply a reversal of long-term trends, as historical data shows that from November to January of the following year is often a traditional strong window for US stocks, with an average increase of 3.54% for the S&P 500. Regarding assets, Bank of America believes that during the August to October period, defensive assets such as the dollar, US Treasuries, and gold tend to perform well. Specifically, gold has a 61% probability of rising during this window since 1992, with an average increase of 2.52%; the yield on US 30-year Treasuries also tends to decline historically. Additionally, energy assets may be an exception in the late summer market. The Bloomberg Energy Index has an average historical increase of 2.42% in August, and oil prices often receive support in late August. Bank of America advises investors to pay attention to the risks posed by seasonal fluctuations and to respond to potential market corrections through allocations in defensive assets.

On July 27, Reuters reported that the yen has recently fallen to its lowest level in nearly 40 years.

On July 27, at the Money Frontier 2026 New Infrastructure Intelligent Computing Summit, Bixin founder Xingkong delivered a speech stating that since 2023, he has been very optimistic about the domestic entrepreneurial environment and investment, and therefore began investing heavily in domestic AI teams. Because previous investments in the US and Singapore showed that their work efficiency is basically one-tenth that of Chinese people, and people abroad are generally not as competitive or intelligent. There is a cultural notion in China that conquering the world only requires a county's worth of talent, like Pei County of the Han Dynasty and Fengyang County of the Ming Dynasty. The same applies to AI now; many AI teams basically only need a squad's worth of talent, such as Kimi and DeepSeek. China's talent density is 10 times that of the US. Another advantage is that Chinese people are a very closely connected group, and much knowledge is open-sourced within the Chinese community. Based on this understanding of talent density and the close connections among talents, Bixin firmly chose to invest in some domestic AI companies. Investing in US AI companies and blockchain is always particularly expensive, the people are unfamiliar, and after investing, it becomes very troublesome.
