Why VanEck Semiconductor ETF (SMH) fell 1.68%
VanEck Semiconductor ETF (SMH) fell 1.68% on September 1, 2026 — MediaTek's $3.5B Nvidia deal intensifies chip competition.
What happened
The VanEck Semiconductor ETF declined 1.7% as the broad Chip Supply Chain selloff accelerated on MediaTek's $3.5 billion Nvidia deal and mounting evidence that foundry capex has peaked after the AI buildout wave.
Why it moved
SMH holds diversified semiconductor and equipment-vendor exposure; as fab capex and wafer-process orders moderate and foundries slow expansions, the entire industry—from chipmakers to suppliers—faces order visibility…
Why it matters
Chip Supply Chain theme: fab capex and wafer-process equipment orders have slowed sharply after quarters of AI-driven buildout, with foundries moderating wafer expansions and legacy chipmakers cutting spending—a…
What would break the thesis
If hyperscaler capex rebounds or new AI inference demand accelerates, foundry capex could stabilize and SMH regains upside; a prolonged slowdown in advanced-node spending would keep pressure on the index.
