AI stock sell-off deepens as investors dump chipmakers

On July 28, 2026, a sell-off in artificial intelligence-related stocks intensified as investors dumped shares of chipmakers across global markets. The decline was driven by growing fears over competition from Chinese firms, rattling the AI trade.

Asian chip stocks slid sharply, with Japan's Nikkei 225 index falling 2.6%, dragged down by semiconductor and metals companies. The losses followed a broader retreat in US markets, where chip firms also fell amid the AI jitters.

The sell-off matters because it signals a potential shift in investor sentiment toward the high-flying AI sector, which has been a major driver of market gains. Concerns that Chinese competitors could erode the dominance of established chipmakers have sparked a reassessment of valuations.

According to reports, the Financial Times noted that the AI stock sell-off continued as investors dumped chipmakers, while Reuters highlighted that Asian chip stocks slid due to China competition fears rattling the AI trade. Bloomberg reported that oil extended its decline and Asian stocks were set for losses, and the Wall Street Journal stated that the Nikkei's drop was led by chip and metals stocks. The BBC also covered the story, noting that chip firms fell in both the US and Asia as AI jitters rattled investors.

The sell-off builds on earlier volatility in the tech sector, where AI-related stocks had previously soared on expectations of rapid growth. However, the emergence of competitive threats from China has introduced new uncertainty, leading to the current wave of selling.

Looking ahead, market participants will likely monitor developments in the US-China tech rivalry and any policy responses that could affect the chip industry. Further volatility is possible as investors reassess the long-term outlook for AI investments.
