AI Slowdown Calls Trigger Sharp Selloff in Asian Tech Stocks

Sometimes it only takes a few sentences from the right people to send shockwaves through global markets. On Monday, AI-linked stocks across Asia fell sharply after prominent artificial intelligence executives called for a slower pace of AI development — and investors clearly took the warning seriously.

Who Actually Said It

Anthropic CEO Dario Amodei urged AI companies to slow the rate at which they develop increasingly powerful models, specifically citing concerns over potential misuse and safety risks. He wasn't alone — OpenAI CEO Sam Altman and xAI chief Elon Musk have also expressed support for slowing AI's pace, according to reports.

SoftBank Took the Biggest Hit

Here's where the numbers get striking. In Japan, SoftBank — a major investor in OpenAI — fell as much as 13.2% in a single trading session. That's not a minor dip; that's the kind of drop that dominates a day's financial headlines on its own.

The Chip Sector Felt It Everywhere

The damage spread fast across the entire semiconductor supply chain. Memory chipmaker Kioxia dropped 9.8%, while Tokyo Electron declined 3.7%. In Taiwan, TSMC — arguably the world's most important chip manufacturer — fell 1.2%. South Korea's SK Hynix dropped 5.3%, and Samsung Electronics declined 3.7%.

China's AI Names Didn't Escape Either

The selloff crossed borders effortlessly. Shanghai-based CXMT fell 2.7%, Semiconductor Manufacturing International Corporation declined 1.4%, and in Hong Kong, Zhongji Innolight dropped 4.1% while Minimax fell 5.4%. Chinese AI developer Z.ai took perhaps the hardest hit of all, falling as much as 10.5% following a discounted share placement.

Why a Safety Warning Triggers a Stock Crash

Here's the underlying logic investors are grappling with: massive amounts of money have been poured into chips, data centres, and computing infrastructure based on the assumption that AI development keeps accelerating. When the very people building these systems suggest slowing down, it directly threatens the growth story that's been propping up valuations across the entire sector.

A Second Factor Working Against Markets

According to Takayuki Miyajima, senior economist at Sony Financial Group, the selling pressure was likely triggered by the weekend's AI slowdown comments — but he also pointed to continuing uncertainty surrounding the Middle East as another factor weighing on overall market sentiment. In other words, this wasn't happening in isolation.

The Tension Nobody Can Resolve Yet

This selloff exposes a genuine fault line: AI companies and researchers face growing pressure to address safety, misuse, and cybersecurity concerns, while investors have simultaneously bet enormous sums on relentless, uninterrupted AI growth. Those two forces are now visibly pulling in opposite directions.

The Bottom Line

A handful of cautionary sentences from AI's own architects erased billions in market value across Japan, Taiwan, South Korea, China, and Hong Kong within a single session. Whether this turns out to be a brief overreaction or the first sign of a genuine reset in AI valuations will depend on what these same executives say — and do — next.
