Best AI and Artificial Intelligence ETFs
AI ETFs bet on the companies building and deploying artificial intelligence. Here is what they hold and whether the valuation makes sense.
Don't have time? Here's what you need to know:
- 1SMH (semiconductors) is the purest AI hardware play; AIQ and BOTZ offer broader AI/robotics exposure
- 2VTI already gives you significant AI exposure — a dedicated AI ETF concentrates the bet further
- 3AI ETFs trade at premium valuations; the hype may already be priced in
- 4Keep AI ETF allocation under 10% of your portfolio due to concentration and valuation risk
AI ETFs: Three Ways to Play the Trend
AI ETFs fall into three buckets: semiconductor ETFs (companies making AI chips — Nvidia, AMD, Broadcom), software/platform ETFs (companies deploying AI — Microsoft, Google, Palantir), and broad AI thematic ETFs that mix hardware, software, and robotics. The purest AI exposure comes from semiconductor ETFs since every AI system runs on GPU chips.
Most AI ETFs have significant overlap with the S&P 500. If you own VOO, you already hold Nvidia (~3%), Microsoft (~7%), Google (~4%), and Meta (~2%). A dedicated AI ETF doubles down on these same companies. Understand that you are concentrating, not diversifying.
Best AI ETFs Compared
| ETF | Focus | Expense Ratio | Holdings | Top Positions | 1-Year Return |
|---|---|---|---|---|---|
| SMH | Semiconductors | 0.35% | 25 | Nvidia ~20%, TSMC ~12% | ~40% |
| BOTZ | Robotics + AI | 0.68% | 45 | Nvidia, Intuitive Surgical, Keyence | ~25% |
| AIQ | AI adoption companies | 0.68% | 85 | Meta, Alphabet, Microsoft | ~30% |
| ROBT | AI + robotics (small/mid tilt) | 0.65% | 80 | Smaller AI companies | ~15% |
| ARKQ | Autonomous tech (active) | 0.75% | 35 | Tesla, Kratos, Iridium | ~10% |
The Valuation Question: Is AI Already Priced In?
Nvidia's stock rose over 200% in 2023 and another 170% in 2024 on AI chip demand. SMH trades at a P/E ratio above 30. The question is whether current prices already reflect the AI growth everyone expects. The dot-com bubble offers a cautionary parallel: the internet was real and transformative, but most internet stocks still crashed 80-90% because valuations outran reality.
For long-term investors, the safer approach is owning VTI (which already holds all AI stocks at market weight) rather than making a concentrated bet through AI ETFs. If you have conviction in AI as a theme, keep the allocation under 10% of your portfolio and understand you are paying premium valuations for expected growth.
Important: AI ETFs carry concentration risk and high valuations. Nvidia alone is 15-25% of most AI/semiconductor ETFs. A single earnings miss from Nvidia could cause a 10-15% fund drawdown in a day.

Frequently Asked Questions
What is the best pure AI ETF?
SMH (semiconductors) is the purest AI hardware play. AIQ is broader, including AI software and platform companies. Neither is 'pure AI' — most holdings have large non-AI businesses. There is no ETF that holds only AI-revenue companies.
Should I add an AI ETF to my portfolio?
Only as a small satellite (5-10% max). VTI already gives you significant AI exposure through Nvidia, Microsoft, Google, and Meta. Adding an AI ETF concentrates your bet on one theme. If AI underperforms expectations (as many hyped technologies do), the concentration hurts.
Is SMH better than QQQ for AI exposure?
More concentrated. SMH holds 25 semiconductor stocks while QQQ holds 100 Nasdaq companies. SMH gives you purer chip/AI hardware exposure but with higher volatility. QQQ is more diversified across tech themes beyond just AI.
