iShares Semiconductor ETF (NASDAQ: SOXX) — A Diversified Way to Invest in the AI Infrastructure Buildout
Artificial intelligence is driving one of the largest technology spending cycles we’ve seen in years, and the numbers continue to grow. According to projections from Dell’Oro Group, global data center capital expenditures are expected to exceed $1 trillion in 2026 as cloud providers race to build the infrastructure needed to support AI applications.
The challenge for investors is determining which companies will ultimately capture the biggest share of that spending. Rather than trying to identify a single winner, the iShares Semiconductor ETF (NASDAQ: SOXX) offers broad exposure to many of the companies positioned to benefit from the AI buildout.
The fund holds approximately 30 semiconductor-related stocks spanning multiple parts of the industry. Its portfolio includes leading AI chip designers such as Nvidia, Broadcom, and Advanced Micro Devices, along with memory-chip specialist Micron Technology. It also includes companies that manufacture the equipment used to produce semiconductors, including Applied Materials.
This diversified approach is important because the AI opportunity extends beyond a handful of headline names. As chipmakers increase production capacity to meet demand, equipment suppliers and other companies throughout the semiconductor supply chain can benefit as well.
The spending trends supporting the sector remain substantial. The four largest U.S. cloud computing providers have collectively guided for more than $700 billion in capital expenditures during 2026, much of it tied to expanding AI infrastructure and data center capacity.
Another advantage of SOXX is its portfolio construction. Unlike some competing semiconductor ETFs, the fund limits how large any single holding can become. Its largest position represents roughly 8% to 9% of assets, while its top 10 holdings account for just under 60% of the portfolio.
That compares favorably to more concentrated alternatives, where a small number of stocks can have an outsized influence on overall performance. The structure helps investors gain exposure to the broader semiconductor ecosystem without becoming overly dependent on one company.
The fund also carries a relatively modest expense ratio of 0.34%, which works out to about $3.40 annually for every $1,000 invested.
Investors should recognize that semiconductor stocks remain cyclical. Demand can fluctuate significantly, and the group has experienced sharp downturns in previous cycles. The sector has also posted strong gains over the past year, which has pushed valuations higher and could lead to periods of increased volatility.
Even so, we believe the long-term opportunity remains compelling. With data center spending expected to top $1 trillion in 2026 and AI infrastructure investment continuing to accelerate, the iShares Semiconductor ETF provides a straightforward way to participate in one of the market’s most powerful growth themes.
