Asian Tech Stocks Fall as AI-Cost Worries Hit SoftBank

Asian equity markets opened Friday’s session under pressure, with technology shares leading the slide as a selloff that began on Wall Street rolled into the region. The standout casualty was Japan’s SoftBank Group, which tumbled around 12% and dragged benchmarks lower.

Asian tech stocks fall as Wall Street weakness spreads

Asia’s major benchmarks slipped early Friday after another soft session for U.S. technology stocks. Japan’s Nikkei 225 and South Korea’s Kospi both opened in the red, with chip and AI-linked names bearing the brunt of the selling. The move extended a stretch of choppy, tech-driven trading that has defined the past two weeks across the region.

The trigger was familiar: investors are growing more cautious about the names that led this year’s artificial-intelligence rally, and that caution is now showing up in Tokyo, Seoul and Hong Kong as quickly as it does in New York.

SoftBank leads the decline

SoftBank Group was the single biggest mover, sinking roughly 12% in one of its sharpest one-day falls of the year. The Japanese conglomerate has become a proxy for the AI investment theme, with large positions and commitments tied to chips, data centres and model developers. When sentiment toward AI spending sours, SoftBank tends to move further than the broader index, in both directions.

Memory-chip maker SK Hynix fell more than 3%, and Arm Holdings — the SoftBank-controlled chip designer — had dropped about 3% in U.S. trading overnight, underperforming the wider semiconductor group.

What’s driving it: the cost of AI

The common thread is the rising cost of building AI infrastructure. For more than a year, spending on data centres, accelerators and power has been treated as an unambiguous positive for the companies supplying the picks and shovels. More recently, the market has started asking harder questions about how much of that capital expenditure will translate into near-term profit, and how long the bill will keep climbing.

That shift in framing matters for Asian markets because the region sits at the centre of the AI supply chain — memory, foundry capacity and components. When the spending narrative is questioned, Asian tech is among the first to feel it.

Apple and Micron send mixed signals

The overnight cues from the U.S. were genuinely mixed. Apple slid more than 6% — its steepest one-day drop since April 2025 — after the company announced price increases on MacBook and iPad models, a move investors read as a sign of cost pressure. That single decline was enough to pull the Nasdaq Composite lower for a fourth straight session, its first four-day losing streak since February.

At the same time, memory maker Micron jumped about 17% after quarterly earnings blew past expectations, with adjusted profit of $25.11 a share against forecasts near $20.78. The split tells the story of the moment: strong fundamentals in parts of the chip sector are not, on their own, enough to offset worries about valuations and AI spending elsewhere.

The wider market picture

Away from technology, the picture was steadier. In the U.S., the Dow Jones Industrial Average actually closed modestly higher and the S&P 500 finished little changed, underlining that the weakness has been concentrated in high-flying tech and AI names rather than the whole market.

That concentration is the key feature of the current pullback. Indices with heavy technology weightings — the Nikkei 225 and Kospi in Asia, the Nasdaq in the U.S. — are swinging more than broader, more diversified benchmarks. For traders, it is a reminder of how much index direction can hinge on a handful of mega-cap names.

What traders are watching

In the days ahead, attention is likely to stay on the AI-spending debate and how individual heavyweights — SoftBank, the major chipmakers and the U.S. mega-caps — respond. Currency moves matter too: shifts in the yen change the calculus for Japanese exporters and for SoftBank’s overseas holdings. None of this points to a single, predetermined outcome; it simply frames where the volatility is concentrated.

For now, the message from this session is narrow but clear: Asian stocks fell because tech fell, and tech fell because the market is reassessing the price of the AI boom.

Key takeaways

• Asian tech stocks fell as a Wall Street selloff spread, with SoftBank down around 12%.
• Concerns about the rising cost of AI infrastructure are the central driver.
• Apple’s 6% drop on price hikes pulled the Nasdaq to a fourth straight loss; Micron rose about 17% on a strong earnings beat.
• Losses are concentrated in tech — the Dow held up and the S&P 500 was little changed.
• Tech-heavy indices like the Nikkei 225 and Kospi are moving more than diversified benchmarks.
