Asian Tech Stocks Plunge After US Midterm Election Results
Asian semiconductor and AI stocks fell sharply as investors feared a Democratic-led US Congress would tighten regulations on AI data centers and slow infrastructure development.
Asian stock markets experienced a sharp rotation on November 5, 2026, following US midterm elections that resulted in a Democratic-led Congress. While broader risk assets and markets in China, India, Australia, and New Zealand rallied, a significant divergence emerged between the AI semiconductor supply chain and the consumer sector.
Samsung Electronics and SK Hynix led a steep decline in South Korea, with shares dropping as much as 7.4% amid fears that the new US Congress would tighten regulations on AI data centers and slow their development. In Japan, the Nikkei 225 fell 0.5%, driven by losses for SoftBank Group, Tokyo Electron, and Advantest. This selling pressure was further exacerbated by reported capacity constraints and slowing growth momentum in financial results from Arm Holdings and Qualcomm Incorporated.
Conversely, the consumer sector saw significant gains. In Japan, Toyota and Fast Retailing experienced strong short covering, while Chinese tech giants Alibaba Group and Tencent performed strongly. The Chinese tech industry took leadership of Asian equities, aided by a drop in Brent crude oil prices as investors speculated that a Democratic Congress might pressure the US to reduce conflict with Iran.
Other notable losses included Trump Media & Technology Group, which saw its stock drop 24.5%, and Tesla, which fell 3.3%. While the Nikkei struggled with chip stocks, the Topix index rose, reflecting a broader market preference for split government control in the United States.
