Wall Street plunges in AI ‘bloodbath’ as tech stocks sell off globally
On July 17, 2026, US stock markets experienced a sharp decline, particularly in technology and AI-related stocks, described as a 'bloodbath' by analysts. The Nasdaq Composite fell 1.9%, its steepest drop in a month, driven by concerns over soaring valuations of AI companies. The sell-off was global, with Japan's Nikkei 225 sinking 4% and Taiwan's Taiex index dropping 6.5% after TSMC fell 7.3% despite record profits. A key trigger was Chinese AI startup Moonshot unveiling its Kimi K3 large language model, which can perform close to US systems at a fraction of the cost, raising doubts about massive AI infrastructure investments. Additionally, renewed Middle East hostilities pushed oil prices above $85 a barrel, boosting energy stocks like Shell and National Grid, which helped the UK's FTSE 100 finish higher.
