Three semiconductor ETFs are competing for the same investor dollar in 2026, each built on a different philosophy for capturing growth in the chip industry. The backdrop is hard to ignore: Deloitte projects that generative AI chips alone will approach $500 billion in revenue in 2026, roughly half of total global semiconductor sales. AI infrastructure buildouts, data center expansions, and the proliferation of edge computing are driving chip demand across every segment of the industry. Each fund structure carries different tradeoffs in concentration, cost, and exposure to smaller chip companies.
iShares Semiconductor ETF: The Category Standard-Bearer
iShares Semiconductor ETF (NYSEARCA:SOXX) is the largest and oldest fund on this list, with net assets of approximately $20.6 billion and an inception date of July 10, 2001. It tracks the NYSE Semiconductor Index and carries an expense ratio of 0.34%.
The fund’s construction is market-cap-weighted, meaning the largest, most liquid chip companies dominate the portfolio. NVIDIA accounts for roughly 8% of the fund, followed closely by Broadcom at just over 8%, Micron at about 7%, and AMD at near 6%. The top ten holdings account for a substantial portion of the portfolio, creating meaningful concentration in the names that have driven the AI chip narrative. That is a feature for investors who believe the largest players will continue to capture disproportionate AI infrastructure spending, and a risk for those concerned about valuation at the top.
The performance data reflects just how much the sector has accelerated. SOXX has returned 33% year-to-date and 133% over the trailing one-year period. The fund also holds names across the full semiconductor value chain, including equipment makers like Applied Materials and KLA Corp, which benefit from chip capacity expansion regardless of which specific chip architecture wins the AI race.
The tradeoff is concentration. The top two holdings together represent a meaningful share of the portfolio, and a drawdown in either NVIDIA or Broadcom would weigh heavily on the fund’s returns.
SPDR S&P Semiconductor ETF: The Equal-Weight Alternative
SPDR S&P Semiconductor ETF (NYSEARCA:XSD) takes a structurally different approach. Rather than weighting by market cap, it tracks the S&P Semiconductor Select Industry Index using a modified equal-weighted methodology. That means no single company dominates the portfolio, and smaller, less-covered semiconductor names get meaningful representation alongside the household names.
The practical effect is visible in the holdings. Impinj, a radio-frequency identification chip specialist, sits at roughly 3% of the fund. Cirrus Logic, Micron, Nvidia, and Astera Labs each carry a weight of near 3%. NVIDIA, which commands more than 8% of SOXX, gets just over 2% here. This equal-weight structure means XSD is a genuine bet on the breadth of the semiconductor industry rather than a concentrated wager on a handful of mega-cap names.
XSD holds 44 positions across chip designers, analog specialists, power management companies, and niche players such as Rigetti Computing and Navitas Semiconductor. For investors who believe the chip boom will lift mid-tier and smaller semiconductor companies as AI infrastructure spending ripples through the supply chain, this fund offers exposure that SOXX simply cannot replicate.
The performance comparison with SOXX is instructive. XSD has returned 21% year-to-date and 118% over the trailing year. The lag relative to SOXX reflects the equal-weight structure’s natural tendency to underperform when the largest names are leading the rally. Over a longer horizon, equal-weight approaches have historically benefited from mean reversion (the tendency for outperformers to slow and laggards to catch up), but that dynamic requires patience. The fund’s expense ratio is 0.35%, essentially identical to SOXX.
The key trade-off: XSD’s smaller- and mid-cap names carry more individual-company risk. Some of its holdings are thinly traded businesses where a single product cycle or customer concentration issue can move the stock dramatically.
Invesco PHLX Semiconductor ETF: The Low-Cost Full-Spectrum Option
Invesco PHLX Semiconductor ETF (NASDAQ:SOXQ) tracks the same PHLX Semiconductor Sector Index that the older, more expensive SOX index has historically referenced, and it does so at a cost that stands out in the category. The fund carries a net expense ratio of 0.19%, meaningfully below the 0.34%-0.35% charged by SOXX and XSD. For long-term holders, that difference compounds into real money over a decade.
The portfolio is market-cap weighted like SOXX but holds 31 positions, making it more concentrated. NVIDIA leads at roughly 13% of the fund, followed by Broadcom at about 10% and Micron at nearly 7%. The top two holdings alone represent a combined weight approaching a quarter of the portfolio. That is the highest concentration of the three funds here, which amplifies both the upside and the downside when the mega-cap chip names move.
What makes SOXQ worth considering is the breadth of the value chain it captures within that concentrated structure. Holdings span chip designers such as NVIDIA, AMD, and Qualcomm; manufacturers such as Taiwan Semiconductor; equipment makers such as Applied Materials, Lam Research, and ASML; and materials suppliers such as Entegris. An investor in SOXQ is not just buying chip designers, they are buying the entire industrial ecosystem that enables chip production, from lithography machines to the chemical slurries used in wafer fabrication.
SOXQ has returned 30% year-to-date and 132% over the trailing year, tracking closely with SOXX, given their similar market-cap-weighted structure. The fund launched in June 2021, so it lacks the multi-decade track record of SOXX, but the underlying index methodology is well-established.
The concentration risk here is real; investors who are comfortable with NVIDIA and Broadcom, which together represent nearly a quarter of their semiconductor allocation, will find SOXQ’s cost advantage compelling. Those who want more diversified exposure should look at XSD instead.
Choosing Between These Three Funds
Cost-conscious investors who want broad semiconductor exposure weighted toward the dominant AI chip leaders will find SOXQ’s lower expense ratio the most compelling argument in its favor. SOXX offers a nearly identical portfolio with a longer track record and deeper liquidity, making it the natural choice for investors who prioritize institutional-grade fund size. XSD belongs in a different conversation entirely: it is the right fund for investors who believe the chip boom will broaden beyond the mega-cap names and want meaningful exposure to mid-tier and specialty semiconductor companies that the other two funds underweight by design.
