Semiconductor Sector Update: AI Demand Roars as Auto Chip Fears Resurface


TMU Research
2025-10-30

The semiconductor sector saw mixed sentiment as SOXX closed at 305.41, down 1.35% on October 30, 2025, . Despite the pullback, the 10-day trend of +0.56% signals continued underlying strength. Attention — the share of media coverage in the Business and Economy category — held at 4%, a level that remains prominently above the 2% threshold. Sentiment, measured on a -10 to +10 scale, stayed strong at +5, maintaining a bullish outlook even as profit-taking emerged following Nvidia’s milestone valuation and Samsung’s profit surge.

Stock Performance

The semiconductor index weakened slightly after several sessions of strong gains. Nvidia (NVDA) — now the world’s first five-trillion-dollar company — dominated headlines, while Broadcom and TSMC also benefited from the AI-driven rally (Yahoo Finance). Nvidia CEO Jensen Huang projected visibility into “half a trillion dollars” in revenue as AI chip orders piled up (Benzinga). However, broader chip stocks took a breather after a week-long surge, suggesting short-term consolidation.

Industry Trends

The day’s headlines captured the widening gap between AI-fueled chip demand and automotive chip shortages. While cloud and data center players like OpenAI, Oracle, and Related Digital announced a new Stargate data center in Michigan, automakers faced renewed semiconductor bottlenecks. A MarketWatch report warned that supply restrictions at Nexperia could roil production lines globally.

Germany’s automotive association (VDA) responded by forming a temporary chip information exchange to mitigate the crisis, while Stellantis set up a “war room” to manage disruptions (Reuters).

Product and Service Development

AI chip innovation remained the dominant growth catalyst. Amazon unveiled Project Rainier — featuring 500,000 Trainium2 chips — which analysts believe could boost AWS revenue by $6 billion by 2026. Meanwhile, Samsung Electronics reported an 80% surge in semiconductor profits, confirming the recovery in memory chips driven by AI infrastructure demand.

CoreWeave, a cloud infrastructure company backed by Nvidia, announced a major expansion, signaling new competition among AI data center providers (TheStreet).

Earnings and Outlook

Tech giants Alphabet, Meta, and Microsoft each highlighted aggressive AI spending in their latest earnings reports. The trio committed to multi-billion-dollar expansions in GPU-powered data centers, with Meta even planning to raise $25 billion in bonds to finance infrastructure investments. Analysts interpreted this spending spree as both bullish for semiconductor demand and a sign of intensifying competition in AI infrastructure (Business Insider).

Analyst Opinions

Despite short-term volatility, analysts remained optimistic. Bank of America reaffirmed bullish projections for AI chipmakers, citing “insatiable demand” for compute power across industries (CNBC). Still, concerns emerged around local opposition to data center construction, with Microsoft flagging this as a potential long-term risk in its investor disclosures.
