Semiconductors Slide as China Tensions and Rare-Earth Curbs Stir Market Anxiety


TMU
2025-10-10

On October 10, 2025, the semiconductor sector faced heavy pressure as the SOXX ETF fell 6.27% to close at 271.99, marking one of its sharpest single-day declines in recent weeks. Despite the setback, the sector’s 10-day trend held slightly positive at 0.11%, reflecting continued underlying resilience amid macro uncertainty. Attention — the measure of media coverage in the Business and Economy category — reached 5%, sustaining a strong presence after several days above the 4% threshold. Sentiment remained bullish at 4.4 on a -10 to +10 scale, showing that market optimism surrounding AI infrastructure and chip demand persisted even amid short-term turbulence.

Semiconductor Sector Sentiment (Oct 1–10, 2025)

Semiconductor Sector Attention (Oct 1–10, 2025)

Industry Trends: AI Infrastructure Fuels Optimism

AI-driven demand continued to dominate semiconductor headlines. Applied Digital’s stock surged after reporting stronger-than-expected revenue on expanding AI data center services (Investopedia). Similar momentum came from IREN, which gained over 50% since late September following a GPU purchase agreement powered by Nvidia chips (Benzinga). The news reinforced investors’ confidence in long-term AI infrastructure spending despite Friday’s sector-wide pullback.

Partnership and Expansion: Global Data Center Investments

Major collaborations highlighted the sector’s strategic growth. AMD’s partnership with OpenAI earned it a price target boost from TD Cowen (CNBC), while OpenAI and Sur Energy announced a $25 billion data center project in Argentina to support advanced AI computing (Yahoo Finance). TikTok’s parent company ByteDance also confirmed plans for a $9 billion data center in Brazil — another signal of expanding global demand for high-performance computing.

Geopolitical and Supply Chain Headwinds

Offsetting these positives were mounting geopolitical risks. China announced rare-earth export curbs critical to chip manufacturing (Bloomberg), blacklisted research firm TechInsights (CNBC), and launched an antitrust investigation into Qualcomm. The series of measures rattled markets, dragging down major chipmakers including Qualcomm, Samsung, and NXP Semiconductors.

Analyst Opinions: Resilient Outlook Despite Volatility

Analysts maintained a cautiously bullish stance. TheStreet highlighted Nvidia’s continued leadership as the “poster child” of the AI boom (TheStreet), while other outlets noted investor enthusiasm around Applied Digital’s AI-driven revenue model. Though short-term volatility persists, the underlying narrative remains constructive: semiconductor demand tied to AI infrastructure is expanding faster than cyclical headwinds can suppress.
