Vanguard ETF Could Beat the S&P 500 Again in 2026 —— Why Investors Are Paying Attention

TradingKey - As investors shift gears from solid performance from US equity for yet another year, focus is turning to predictions on performance for the Vanguard ETF in 2026 relative to overall market performance. The S&P 500 has therefore become the default benchmark for many in the market; however, strong performance has resulted from a number of sector-based ETFs that are linked to AI and digital infrastructure technology.

This type of thinking reflects a fundamental issue in relation to investors seeking an asset allocation strategy, i.e., should investors continue to hold a diversified portfolio, or should they have a larger weighting towards those sectors that will drive the next major growth phase?

Why This Vanguard ETF Has Outperformed

The Vanguard Group Information Technology ETF (VGT) focuses specifically on technology firms, in contrast to the total S&P 500. In 2025, the S&P500 appreciated approximately 17% while VGT increased approximately 23%. This is part of many years of relative outperformance beginning in 2004, and seems to continue into the future.

The primary reason for this performance gap is the focus of VGT's holdings on higher growth industries.

While the S&P 500 consists of a range of industries such as banks, electric, natural gas and other utility providers along with energy producers and consumer staples, VGT allocates a majority of its funds toward software, semiconductor and digital type infrastructure companies—the areas that have seen the greatest percentage growth of total earnings and investment capital.

The Largest Holdings Drive Performance

Some of VGT's largest holdings include (but are not limited to) NVDA, AAPL, MSFT, AVGO and ORCL. These five companies alone represent a vast majority of VGT's total asset allocation which means that VGT's performance is strongly correlated with the performance of the largest recipients of capital from AI and cloud technology.

Concentration can be powerful for performance during periods of positive sentiment. Semiconductor demand related to data centers, training AI models, network gear, and enterprise cloud spending is still very much in demand. If these trends persist, VGT and other sector-based ETFs may once again significantly outperform broad market indices.

Why It Could Beat the S&P 500 in 2026

There are three reasons for the bullish argument for the ETF in 2026.

• AI infrastructure spending continues to grow. Corporations continue to invest in graphics processing units (GPUs), memory, networks and data centers.
• Cloud service providers are monetizing their backlog of demand, which may lead to higher profitability for large capitalized software and infrastructure companies.
• The current leaders in the market remain concentrated. If mega-cap technology shares continue to drive returns in the index, concentrated holdings may outperform diversified holdings for another cycle.

Potential Risks For Investors

Outperformance is never certain.

Technology is still trading at a significant premium to traditional valuations and a decline in spending, if AI earnings miss, or if rising interest rates could adversely impact multiple.

Because these ETFs have less diversification than the S&P 500, periods of decline could be more severe.

If the current leadership of the broader market expands to financial, health-care, industrial, or energy companies, the S&P 500 could once again outperform.

Bottom Line

If AI's momentum continues, then a technology-centered Vanguard ETF could again outperform the S&P 500 by 2026. If you're willing to take on more volatility, this is an attractive investment.

If you're prioritizing balance and lower concentration risk as an investor, it is possible that broad-based indices will continue to be the better, long-term strategy.
