The AI Chip Boom: A Critical Test for Semiconductor ETFs

SOXX ETF US4642875235

The semiconductor sector, a primary beneficiary of the artificial intelligence revolution, now faces a pivotal moment of validation. As the iShares Semiconductor ETF (SOXX) navigates this landscape, the market's lofty expectations are set to be scrutinized by a wave of corporate earnings. Following robust gains earlier this year, investors are keenly assessing the durability of the current infrastructure expansion cycle.

A staggering $650 billion in AI infrastructure spending is projected for 2026 by four American technology behemoths: Alphabet, Amazon, Meta, and Microsoft. This figure represents a remarkable 60% increase over prior-year plans, channeling immense capital directly into the chip ecosystem. The demand surge is now visibly impacting the memory market, a critical component for AI systems, where DRAM prices have skyrocketed by as much as 95%. This dynamic has provided a significant tailwind for SOXX holding Micron Technology.

Foundry Giant Signals Sustained Demand

Adding further confidence to the sector's outlook, Taiwan Semiconductor Manufacturing Company (TSMC), the world's leading contract chipmaker, has raised its 2026 capital expenditure budget. The company now plans to invest up to $56 billion, marking a minimum increase of 27% year-over-year.

TSMC's management points to a multi-year demand cycle for high-performance computing and AI-specific semiconductors. The fundamental environment for chip manufacturing remains strong, bolstered by cloud service providers securing production capacity directly with foundries like TSMC.

A Reality Check from the Broader Market

Beyond the dominant AI narrative, a crucial test of broader semiconductor health arrives with the latest earnings report from ON Semiconductor. The company, set to release fourth-quarter results after the U.S. market close, offers a window into demand within the automotive and industrial electronics segments—areas outside the immediate AI hype.

Market experts anticipate adjusted earnings per share of $0.62 on revenue of $1.54 billion. Trading near its 12-month high, ON Semiconductor's stock is under pressure to deliver results that justify its valuation. Further volatility is expected tomorrow with the earnings release from Lattice Semiconductor.

A Cautious Macro Backdrop

Despite a strong January that saw the SOXX ETF advance by 12%, a recent pullback of 4.6% in early February serves as a reminder of the market's sensitivity. This correction was triggered in part by cautious forward guidance from industry leaders such as Advanced Micro Devices (AMD).

The current investment climate is nuanced. While major indices like the Dow Jones have breached historic milestones, crossing the 50,000-point threshold, sentiment indicators like the Fear & Greed Index reading of 72 signal a market in "Greed" territory. In such an environment, even minor disappointations can trigger outsized reactions. Consequently, the market's response to ON Semiconductor's guidance will be a key indicator of whether the wider industrial chip sector can maintain pace with the high-flying AI segment.
