Asian Tech Stocks Tumble as AI Rally Falters on Valuation Concerns

Asian technology stocks suffered a sharp reversal on July 28, 2026, as investors soured on AI-linked names that had fueled months of gains. The sell-off hit major players across the region, signaling growing anxiety over whether the artificial intelligence boom can justify its hefty price tag.

SoftBank Leads Decline

SoftBank Group fell approximately 7% as concerns mounted over AI funding and widening valuation gaps. The Japanese conglomerate, which has positioned itself as a major backer of AI ventures, saw its shares tumble as investors reassessed the sustainability of rapid AI-driven growth.

The decline extended beyond Japan. South Korea's KOSPI index plunged nearly 11%, driven by heavy selling of chipmaking stocks including SK Hynix and Samsung Electronics. The benchmark hit its lowest level in three months as semiconductor names bore the brunt of the rout.

Questions Mount Over AI Spending

The reversal marks a stark shift from the optimism that propelled Asian tech shares to record highs in recent months. Investors who once cheered AI demand now question whether the massive capital expenditures required for AI infrastructure will deliver commensurate returns.

Analysts point to two converging pressures: the enormous costs of building AI data centers and chip fabrication facilities, and intensifying competition from China's advancing semiconductor capabilities. Beijing has made chip self-sufficiency a national priority, pouring resources into domestic production that could erode the market share of established players.

A Reset for Expectations

Market watchers describe the move as a potential reset rather than a collapse of the AI thesis. The region's technology sector had rallied sharply on expectations that AI would transform industries from cloud computing to consumer electronics. But as earnings season approaches, investors are demanding evidence that these investments will translate into profits.

The July 28 sell-off reflects a broader recalibration across global markets. U.S. technology stocks have faced similar pressure as traders weigh AI spending against near-term returns. The question now is whether this represents a healthy correction after an extended rally or the beginning of a more sustained downturn.

For Asian exporters tied to the semiconductor supply chain, the stakes are particularly high. South Korea and Taiwan have built economic models around chip manufacturing, and any prolonged weakness in AI demand could ripple through employment and growth forecasts.

Investors will be watching closely for signs of stabilization in coming sessions. If the decline proves to be profit-taking rather than a fundamental reassessment, buyers may step in quickly. But if concerns over AI valuations and Chinese competition deepen, the correction could extend further.
