1. Despite 23x Less Private AI Investment, China Closes Gap to 2.7% Through All-Out National Effort

- Key Summary: China has narrowed the performance gap in top-tier models with the United States to 2.7% through state-led AI investment. In the Arena Leaderboard evaluation, Anthropic's Claude Opus 4.6 scored 1,503 points and ByteDance's Doubao Seed 2.0 scored 1,464 points, narrowing the score gap between the two models. In terms of private investment, however, the U.S. invested 285.9 billion dollars last year, 23 times more than China's 12.4 billion dollars, and maintains its lead in infrastructure such as data centers. As a result, China leads the U.S. in the adoption of industrial robots and the production of AI PhD talent, but still lags in paper citation rates and patent impact.

2. Amazon, With Cloud Profit Up 64%, Raises This Year's Capital Expenditure to 220 Billion Dollars

- Key Summary: Amazon recorded revenue of 200.61 billion dollars (about 285 trillion won) in the second quarter this year, surpassing 200 billion dollars in quarterly revenue for the first time. The cloud business (AWS) drove the results, with operating profit surging 64% year-on-year to 16.621 billion dollars. Along with this, Amazon raised its capital expenditure (CAPEX) forecast for this year by 10% to 220 billion dollars in just five months, and the combined second-quarter capital expenditure of the four major hyperscalers (operators of ultra-large data centers), including Alphabet, Microsoft, and Meta, totaled 165 billion dollars, a 87.1% surge from a year earlier. Meanwhile, Apple presented a fourth-quarter revenue growth outlook below market expectations, citing memory price increases and supply shortages.

3. Dizzying KOSPI: After Falling 17% Over Three Days, Soars 18% in a Single Day

- Key Summary: The KOSPI plunged 17.20% over three days and then surged 17.91% in a single day, recording its largest-ever gain. On the 31st, the KOSPI closed at 6,595.45, up 1,001.89 points from the previous trading day, a figure that exceeds the gain during the 2008 financial crisis (11.95%). Samsung Electronics (005930) closed at 262,500 won, up 26.81%, and SK hynix (000660), SK Square (402340), and Samsung Electro-Mechanics (009150) all hit their upper price limits, with SK hynix hitting its limit for the first time in 17 years since 2009. However, the index is 22% lower than at the end of June, and experts expect a volatile market with alternating rises and falls to continue for the time being.

4. Splitting Off a Major Revenue Source to Prepare for War: Musk Considers Separating Tesla's China Business

- Key Summary: Elon Musk is considering separating Tesla's China business from its U.S. operations to prepare for geopolitical tensions, the Wall Street Journal (WSJ) reported. This is interpreted as a measure to resolve potential conflicts of interest that could arise during the pursuit of a merger between Tesla and SpaceX. SpaceX is a major defense company with a high proportion of transactions with the U.S. government, with 20.9% of its revenue last year coming from the U.S. government, and concerns have also been raised that the know-how of Tesla's China factory could be transferred for U.S. military use. Meanwhile, Musk denied the related report on his social media account, calling it "absurd fake news."
