Japan’s Nikkei average fell 407 yen on the day, with SoftBank Group sliding to a two-and-a-half-month low as investors kept selling AI-linked names on worries that the sector’s capital spending boom is getting harder to justify.
Nikkei Falls as SoftBank Drops on AI Spending Worries

The move matters because SoftBank has become a high-beta proxy for the AI trade in Japan, and its weakness dragged on a market already sensitive to swings in semiconductor shares and global tech sentiment. When the market turns against AI capex, it tends to hit the same cohort that has led much of the Nikkei’s recent gains, leaving the benchmark vulnerable even when broader domestic demand stocks hold up better.
SoftBank Group was among the sharpest drags, temporarily falling to its lowest level in about 2.5 months. The stock has been whipsawed by investor concern that heavy AI investment may take longer to translate into returns, a theme echoing across Asia as traders reassess valuations in the region’s technology complex.
Domestic demand stocks, however, showed relative resilience, helping limit the damage to the broader market. That divergence suggests investors are rotating away from export- and AI-sensitive names toward companies with more defensive earnings streams and less dependence on the next wave of chip and cloud spending.
The risk for investors is that the Nikkei remains exposed to any further selloff in global AI shares, especially if U.S. tech weakness spills over into Asian markets. With the yen and safe-haven flows still a key backdrop, the next catalyst will be whether AI capex concerns deepen or stabilize as markets look ahead to earnings and guidance from Japan’s biggest technology-linked names.
