The raging bull market slammed on the brakes: a global chip stock chain-reaction stampede triggered by "turning blue"

US tech stocks sold off sharply on November 5, with the Nasdaq falling about 5.5% into correction territory and the Philadelphia Semiconductor Index dropping more than 12%, as Nvidia, AMD and Micron all declined, after midterm elections put Democrats in control of both chambers and shifted investor focus to local resistance to AI data-center construction. The selloff spread across Asia on November 6, with Japan's Nikkei down more than 6% led by semiconductor-equipment names Advantest, Tokyo Electron and Kioxia, while South Korea's Kospi plunged more than 8% at the open and triggered a circuit breaker as Samsung Electronics and SK Hynix fell nearly 10% and 12%, respectively, after the Kospi had already lost 5.28% on November 5 and the two companies shed more than $140 billion in combined market value. The trigger was a wave of local ballots: of 41 data-center-related referendums across 10 states tracked by Ballotpedia and media outlets, all but one in a small North Dakota town passed measures restricting, pausing or banning new data centers, with Ohio alone accounting for 21 and Joliet, Illinois, drawing nearly 80% support for restrictions. State-level politics reinforced the signal, as newly elected governors in Texas (Gina Hinojosa), Ohio (Amy Acton) and Georgia (Keisha Lance Bottoms) all back data-center pauses, and Bloomberg reported that roughly 40% of planned US data-center capacity sits in states whose new governors have pledged to slow buildouts, with more than 140 projects already delayed or canceled amid local opposition. The moves mark a repricing of the US data-center buildout timeline across the AI supply chain rather than confirmation of weaker demand: Japan's equipment makers are exposed to longer-order-cycle capex assumptions, while Korea's memory names face faster price and utilization adjustments given their role supplying HBM and advanced DRAM
