Key takeaways

  • Two funds with “AI” in the name may own very different companies and follow different rules.
  • A thematic ETF can overlap heavily with a broad technology or large-cap index while charging a higher fee.
  • Fees, concentration, turnover, liquidity, and index methodology matter more than the label.

What happened

CNBC reported on July 23 that a JPMorgan analysis found a dramatic increase in AI-themed ETFs despite a difficult quarter for parts of the category.

More product choice can help investors express a view, but it also makes fund comparison harder. One AI ETF may own semiconductor companies, another may focus on software, and another may hold robotics, utilities, data-center infrastructure, or companies selected through a broad keyword screen.

The practical question is not “Which AI ETF will win?” It is what exposure am I actually buying, and what extra costs and concentration come with it?

Start with holdings, not the fund name

Read the fund’s current holdings and index methodology. Ask:

  • How much is invested in the ten largest positions?
  • Are the holdings mostly companies already prominent in a broad-market index?
  • Does the methodology define AI revenue, patents, spending, or business involvement?
  • Is the portfolio equal-weighted, market-cap-weighted, or actively managed?
  • How often does it rebalance?

A fund can appear diversified because it owns dozens of securities while still deriving much of its risk from one industry, one factor, or a few mega-cap companies.

Calculate the fee hurdle

An expense ratio is deducted from fund assets, reducing the return available to shareholders. The annual percentage may look small, but the dollar effect compounds over time.

Use the ETF fee drag calculator to compare a thematic fund against a lower-cost benchmark. Enter the starting investment, expected additions, gross return assumption, and fund fee.

The result is not a prediction. It shows how much additional value the strategy must create merely to offset its higher ongoing fee.

Check overlap with what you already own

An investor who already holds a broad U.S. stock fund may already own many of the largest AI beneficiaries. Adding a thematic ETF could increase concentration rather than create a new source of diversification.

Compare the top holdings and sector weights. The portfolio rebalancing calculator can help translate a target allocation into dollar changes, but it cannot determine an appropriate personal allocation.

Liquidity and trading costs still matter

New or small funds may trade with wider bid-ask spreads. A market order placed during a volatile period can add a hidden cost beyond the published expense ratio.

Investors should inspect:

  • Assets under management
  • Average trading volume
  • Bid-ask spread
  • Premium or discount to net asset value
  • Fund closure and liquidation language
  • Tax treatment and capital-gain distributions

A simple comparison worksheet

For every AI ETF under consideration, record:

1. Expense ratio 2. Number of holdings 3. Top-ten concentration 4. Largest sectors 5. Index or active methodology 6. Rebalance frequency 7. Assets and typical spread 8. Overlap with existing funds 9. Three-year history, if one exists 10. Benchmark used to judge the strategy

Do not compare a young thematic ETF only against its own marketing benchmark. A broad, low-cost index is often the more revealing baseline.

What to watch next

Watch whether new AI funds attract durable assets, whether their holdings become more differentiated, and whether performance survives fees and a full market cycle. A strong quarter does not establish a repeatable process, and a weak quarter does not by itself disprove a long-term thesis.

The useful edge is knowing exactly what you own before the theme becomes a slogan.
