SoftBank Group's shares plunged over 8% Friday as a global selloff in AI-linked stocks accelerated, with investors growing increasingly nervous about sky-high valuations across the sector. The Japanese conglomerate's decline comes after a volatile week that saw the stock drop 10% on Wednesday - its worst single day since April - before bouncing back 3% Thursday only to resume falling.
The AI investment bubble is showing serious cracks, and SoftBank is feeling the full force of investor anxiety. The Japanese tech giant's shares tumbled over 8% Friday as a coordinated selloff in artificial intelligence stocks spread from Wall Street to Asian markets, leaving no major AI player untouched.
This latest drop caps off a brutal week for SoftBank, which saw its stock crash 10% Wednesday in what marked the company's worst single trading day since April. A brief 3% recovery Thursday proved short-lived as global sentiment toward AI investments continued deteriorating.
The selloff reflects growing unease about the astronomical valuations that have defined the AI sector throughout 2024. Investors who once scrambled to get exposure to anything AI-related are now questioning whether the technology can deliver returns that justify current stock prices. SoftBank, with its sprawling portfolio of AI investments spanning infrastructure companies, semiconductor firms, and application developers, has become a lightning rod for this skepticism.
The contagion spread well beyond SoftBank across Asian tech markets. Semiconductor testing equipment maker Advantest dropped over 6%, while chipmaker Renesas Electronics fell nearly 4%. Tokyo Electron, which produces chip manufacturing equipment, declined 1.46%. Even South Korean memory chip giant SK Hynix, typically more insulated from market swings, lost 0.51%.
But the real damage started overnight in U.S. markets, where AI darlings faced their own reckoning. Qualcomm dropped almost 4% despite reporting strong quarterly results, after warning it could lose future Apple business. AMD, which had been a standout performer Wednesday, gave back those gains with a 7% slide.
The casualties extended to other high-profile AI plays. Palantir and Oracle both fell about 7% and 3% respectively, while even the so-called "Magnificent Seven" tech giants couldn't escape the downdraft. Nvidia and Meta both finished lower, signaling that the AI selloff has reached the sector's most established players.
