7.1-Magnitude Earthquake in Kumamoto Raises Risk to Semiconductor Supply Chain

A 7.1-magnitude earthquake struck Japan's Kumamoto Prefecture on July 28, 2026, killing at least 13 people and injuring dozens. The quake disrupted power to over 48,000 households, halted transport, and forced evacuations at semiconductor plants including TSMC and Sony. The region, a key semiconductor hub, faces heightened supply chain risk. Japan's government activated emergency response, while Taiwan donated 5 million New Taiwan dollars for relief.

SoftBank Building AI Data Center in US; OpenAI Eyes Tenancy, Seeks $250 billion Nvidia Credit Guarantee

SoftBank Group is constructing an AI-focused data center in the US, and OpenAI is considering moving in. OpenAI is in talks with Nvidia to secure roughly $250 billion in credit guarantees that would underpin a lease agreement. The guarantee would cover lease costs and debt for facility construction, potentially easing access to financial institution funding for the unprofitable, privately held AI company. SoftBank announced in March that construction of the large-scale data center would begin this year in Ohio, as part of a $500 billion joint US-Japan project.

Huawei Plans 2027 Mass Production of Glass-Substrate AI Chips, Partners with BOE

Huawei plans to mass-produce AI chips using glass substrate technology by 2027, partnering with domestic companies including BOE and Visionox and importing key materials from South Korea. The glass substrate offers advantages such as high flatness for dense 3D stacking, reduced warpage, lower power leakage, and higher data rates, helping Huawei compensate for limited access to EUV lithography. The company has captured about 60 percent of China's AI chip market, partly due to Nvidia's withdrawal amid geopolitical factors.

Changxin Technology Lists on A-Share Market on July 27, 2026, Marking China's Breakthrough in DRAM from Zero

Changxin Technology (Changxin Memory) began trading on the A-share market on July 27, 2026, representing a significant breakthrough in China's DRAM sector. The listing breaks the long-standing monopoly of Samsung, SK Hynix, and Micron in the memory chip market, achieving a from-zero-to-one breakthrough for domestic DRAM. The company's development has been supported by national semiconductor policies, market demand for self-controlled memory chips, entrepreneurial efforts, long-term investment from Hefei state-owned industrial funds, and surging demand from AI computing infrastructure. The IPO provides stable, long-term funding for R&D, production expansion, and product upgrades, helping to narrow the technology gap with global leaders and secure China's semiconductor supply chain. However, Changxin faces severe challenges including technology gaps in advanced lithography, yield rates, and patent portfolios, as well as market cyclicality and pricing power of incumbents.
