SoftBank shares sank more than 9% on July 17, leading a broad selloff across Asian semiconductor stocks that tracked a steep decline on Wall Street, as Fortune reported that tech stocks are leading a global selloff specifically because investors are losing confidence in the AI chip trade, not the market more broadly.
The decline is notable for its concentration: rather than a broad, index-wide risk-off move, the selling is landing hardest in AI chip and infrastructure names, from SoftBank's outsized stake in Arm and various AI ventures to the wider Asian foundry and equipment supply chain. CNBC separately reported that ASML is navigating an increasingly delicate tightrope between sales growth and geopolitical pressure amid the US-China AI feud, meaning the lithography-equipment layer of the chip supply chain now faces both a demand-confidence question from investors and an escalating export-control risk from Washington and Beijing simultaneously.
The timing compounds an already turbulent 48 hours for AI-linked equities: the selloff lands the same stretch as Alphabet's roughly $200 billion market-cap hit on the Gemini 3.5 Pro delay and Moonshot's Kimi K3 release, which Axios framed as China erasing America's AI lead. Investors are effectively re-pricing AI exposure on two fronts at once -- execution risk at US labs and competitive threat from Chinese models -- inside a single trading window.
For VCs and LPs with public AI-infrastructure exposure through secondary positions or fund marks tied to chip and semiconductor comparables, a decline concentrated specifically in AI-adjacent names rather than the broader market is a meaningfully different signal than routine volatility -- it suggests the market is questioning the AI capex cycle's near-term returns, not just reacting to a macro shock.
The bear case: sharp single-week selloffs in high-multiple AI and chip names have happened repeatedly throughout the 2025-2026 AI buildout without derailing the underlying capex trend, and TSMC's own 77% profit jump earlier this month suggests order books remain robust regardless of how sentiment swings week to week. What to watch next: whether the selloff extends into TSMC and Nvidia's own shares, and whether ASML's next earnings update reaffirms or walks back its recent forecast hikes.
