每经编辑｜吴永久 周三，在美股甲骨文盘前暴涨超29%的消息刺激下，A股AI硬件股大涨，胜宏科技、工业富联、景旺电子等暴涨。 消息面上，引发市场狂热的是，甲骨文宣布未实现履约义务（尚未确认的已签约收入）已经达到4550亿美元，同比暴增359%，其中仅第一季度就新增了 3170亿美元。这一爆炸性增长主要源于公司与OpenAI、xAI、Meta等一系列顶尖AI公司签订了大规模云合同，使其成为AI模型训练的关键基础设施提供 商。首席执行官Safra Catz直言："甲骨文已成为AI工作负载的首选之地。"这些合同的签订，意味着甲骨文的云基础设施（OCI）已成为训练尖端AI模型 的关键平台。基于强劲的需求和已锁定的合同，Safra Catz对未来给出了极为乐观的指引。她预计，甲骨文云基础设施（OCI）本财年将增长77%至180亿 美元，并在未来四年内依次增长至320亿美元、730亿美元、1140亿美元和1440亿美元。 在每日经济新闻App举办的掘金大赛中，第73期比赛在周一开始，目前开赛三天，比赛时间一周，目前选手们踊跃报名入场。大赛为模拟炒股，模拟资金 50万元。报名时间为9月6日到9月12日，比赛时间为9月8日到9 ...

Economic Overview - US non-farm payroll data was disappointing, raising recession concerns and increasing expectations for interest rate cuts, with investors betting on three cuts by the Federal Reserve this year and a 50 basis point cut in September [1] - US stock indices opened high but closed lower due to fears that the Fed's actions may lag behind the economic situation, with the S&P 500 down 0.32%, Dow Jones down 0.48%, and Nasdaq down 0.03% [1] Market Performance - Nasdaq Golden Dragon China Index rose by 1.16%, with notable gains in Chinese concept stocks such as Fangdd up approximately 33%, Canadian Solar up 15%, and Daqo New Energy up over 8% [2] - US Treasury yields fell across the board, with the 10-year yield dropping over 8 basis points and the 2-year yield reaching its lowest level since 2022 [3] - Gold prices increased by 1.16%, reaching a record high of $3600 per ounce, while US oil prices fell by 2% to a three-month low [3] Corporate Developments - OpenAI is projected to consume $115 billion in cash over the next four years, aiming for $200 billion in revenue by 2030 [3] - NAND manufacturer SanDisk announced a 10% price increase across all channels for consumer products [6] - Nvidia plans to switch to silicon carbide substrates for its Rubin processors by 2027 to enhance performance [7] Domestic Events - The People's Bank of China reported that gold reserves increased to 74.02 million ounces at the end of August, marking the tenth consecutive month of gold accumulation [8] - The China Securities Regulatory Commission is seeking public opinion on the draft of the "Special Preventive Measures for Anti-Money Laundering" [9] Market Strategy Insights - Analysts remain optimistic about the A-share market, suggesting that recent adjustments are mainly due to profit-taking and structural trading, with significant support from the 20-day and 60-day moving averages [10] - The market is expected to benefit from the Fed's interest rate cut expectations, which may strengthen the RMB and attract foreign investment into Chinese assets [10] - The strategy team at Xingsheng suggests that the market will gradually shift from extreme differentiation to a more diversified performance across sectors [10] Industry Trends - The commercial space industry is expected to expand significantly over the next 1-5 years, focusing on low Earth orbit and deep space resource utilization [13] - Tesla's new compensation plan for CEO Elon Musk could be worth up to $1 trillion, contingent on the company's market value reaching $8.5 trillion, with a focus on robot deliveries [14] - Nvidia's shift to silicon carbide for advanced packaging is anticipated to improve thermal performance in high-power GPU chips [15] - Meta has raised its sales forecast for smart glasses due to strong demand, increasing orders for Qualcomm's AR1 chips by 20% [16]

Core Viewpoint - The Taiwanese silicon carbide (SiC) industry is experiencing rapid growth due to increasing demand from Nvidia for advanced GPU performance, despite challenges in the global SiC supply chain [3][4]. Group 1: Industry Developments - Wolfspeed, a global leader in SiC, declared bankruptcy in May, while Taiwan's GlobalWafers announced plans to develop new SiC products with clients [3]. - The shift from silicon to silicon carbide for interposer layers in advanced semiconductor processes is being driven by Nvidia's new Rubin processor, which aims to enhance performance [3][4]. - The advanced chip plans are expected to handle power levels up to 1000 volts, significantly higher than Tesla's fast charging voltage of 350 volts [4]. Group 2: Technical Insights - Nvidia's NVLink technology benefits from closer GPU and memory proximity, leading to faster data transfer and improved power efficiency, making SiC an attractive material due to its superior thermal conductivity [4]. - The transition to SiC interposer layers requires advanced cutting techniques, as SiC's hardness is comparable to diamond, and poor cutting can lead to unusable surfaces [4][5]. - The production of larger single-crystal SiC wafers is a key differentiator for Taiwanese manufacturers compared to Chinese competitors, who primarily produce 6-inch and 8-inch wafers [4]. Group 3: Future Outlook - TSMC is collaborating with global manufacturers to develop SiC interposer manufacturing technology, while new laser cutting machines are being developed by companies like DISCO [5]. - Nvidia's first-generation Rubin GPU will still use silicon interposer layers until the new cutting equipment is available, with SiC expected to be integrated into advanced packaging by the end of 2025 [5].
