At the midday close, China's most-active futures contracts were mostly lower. Pure benzene hit the daily down limit, falling 5.99%. Fuel oil, LPG and SC crude dropped more than 6%; polypropylene and low-sulfur fuel oil (LU) fell about 6%. Polypropylene monthly-average, methanol, asphalt and propylene declined over 5%. On the upside, container shipping Europe route gained nearly 4%, while ferrosilicon, platinum, urea, rapeseed meal and eggs rose more than 1%.

Elon Musk said Grok 4.8 has entered the reinforcement learning (RL) phase after rewriting the RL and inference stack from JAX and SGLang to C/C++. Pretraining is complete; supervised fine-tuning (SFT) data was heavily cleaned and evaluation metrics have begun to improve. A limited gray rollout to Bot users is planned later this week. Musk said 4.8 will be substantially different from 4.7 and, while not yet striking, the new foundation should produce a differentiated product over time.

在AI硬件需求擠佔全球產能、推高覆銅板等關鍵原材料價格的背景下，印度電子製造業正面臨PCB成本高企與供應短缺的雙重壓力。作爲智能手機、汽車等產品的核心部件，PCB產能正加速流向高利潤的AI應用領域，導致傳統電子企業供應趨緊。印度雖通過補貼政策迅速擴大電子組裝和出口，但PCB原材料約88%依賴進口，供應鏈脆弱性突出，覆銅板價格漲幅高達200%至350%，短缺可能持續一年。成本壓力已沿產業鏈傳導，部分製造商與汽車客戶協商提價，並最終轉嫁至消費者；今年節日季蘋果、家電和車企不減價反而漲價，進一步凸顯供應約束對需求的潛在抑制。印度推動本土PCB產能建設的補貼項目預計明年投產，但短期內供應鏈緊張難以明顯緩解。
