AI ETFs let you invest in artificial intelligence as a theme — across chips, cloud, software, and robotics — in a single fund. But “AI ETF” covers very different things depending on the fund. Here’s how to compare them.
Major AI ETFs Compared
| ETF | Ticker | Expense Ratio | Focus | AUM (approx.) |
|---|---|---|---|---|
| Global X AI & Technology ETF | AIQ | 0.68% | Broad AI: hardware + software + platforms | ~$1.5B |
| iShares Robotics & AI Multisector ETF | IRBO | 0.47% | Equal-weight; robotics + AI | ~$700M |
| Global X Robotics & AI ETF | BOTZ | 0.68% | Industrial robotics + AI | ~$2.5B |
| Roundhill Generative AI & Technology ETF | CHAT | 0.75% | Generative AI-focused | ~$300M |
| ROBO Global Robotics & Automation ETF | ROBO | 0.95% | Robotics + automation + AI | ~$1.3B |
| Invesco AI and Next Gen Software ETF | AIIQ | 0.60% | AI software + enterprise applications | ~$400M |
AUM approximate. Check fund provider for current data.
What Each Fund Actually Holds
AIQ (Global X AI & Technology ETF): Broad basket including NVIDIA, Microsoft, Alphabet, Meta, and international AI companies. Tilted toward large-cap US tech.
BOTZ (Global X Robotics & AI ETF): More industrial — FANUC, ABB, Keyence, Intuitive Surgical, plus NVIDIA. Strong international component. Less “pure AI” and more “automation.”
IRBO (iShares Robotics & AI Multisector ETF): Equal-weight methodology gives more exposure to mid-cap AI companies. Lower concentration in mega-caps than AIQ.
CHAT (Roundhill Generative AI): Specifically targets generative AI — OpenAI infrastructure plays, NVIDIA, Microsoft/Azure, Anthropic partners. More concentrated and recent.
Typical Top Holdings Across AI ETFs
| Company | Relevance to AI |
|---|---|
| NVIDIA (NVDA) | GPU chips powering AI training and inference |
| Microsoft (MSFT) | Azure AI, Copilot, OpenAI partnership |
| Alphabet (GOOGL) | Google DeepMind, TPUs, Gemini, cloud AI |
| Meta (META) | Llama open models, AI-driven ad targeting |
| Amazon (AMZN) | AWS Bedrock, custom Trainium chips |
| TSMC (TSM) | Manufactures NVIDIA, Apple, AMD chips |
| ASML (ASML) | EUV equipment enabling advanced chip production |
| Salesforce (CRM) | Enterprise AI agents and CRM automation |
The Overlap Problem
Before buying an AI ETF, check how much overlap you already have. If you own:
- QQQ (Invesco Nasdaq-100 ETF): Already holds NVIDIA (~8%), Microsoft, Alphabet, Meta, Amazon, AMD
- VOO or VTI: Already holds the same mega-caps at similar or larger weightings than many AI ETFs
Many AI ETFs are largely a repackaging of tech mega-caps at a higher expense ratio. True differentiation comes from: equal-weight methodologies (IRBO), industrial robotics (BOTZ), or genuinely narrower AI focus (CHAT).
How to check overlap: Use the ETF overlap tools at etfrc.com or portfoliovisualizer.com before buying.
AI ETF vs. Semiconductor ETF
| Feature | AI ETF (e.g., AIQ) | Semiconductor ETF (e.g., SOXX) |
|---|---|---|
| NVIDIA exposure | Yes | Yes |
| Software companies | Yes | No |
| Cloud platforms | Yes | No |
| Chip equipment (ASML, AMAT) | Sometimes | Yes |
| Industrial robotics | Sometimes | No |
| International holdings | Yes | Yes |
| Pure chip-sector exposure | No | Yes |
AI ETFs are broader; semiconductor ETFs are more focused on hardware infrastructure.
Expense Ratios: What You’re Paying
AI ETFs are expensive by index fund standards:
| Fund Type | Typical Expense Ratio |
|---|---|
| Broad market index fund (VTI, VOO) | 0.03%–0.05% |
| Sector ETF (XLK, SMH) | 0.13%–0.35% |
| AI ETF | 0.47%–0.95% |
On $50,000 invested, a 0.68% AI ETF costs $340/year. A 0.03% broad market fund costs $15/year. Over 20 years, the difference compounds significantly. Thematic ETFs need to meaningfully outperform the broad market just to break even on fees.
Key Risks
Index definition risk: How the AI index defines “AI company” changes. Companies can enter or exit. Methodologies differ significantly between funds.
Concentration: NVIDIA alone may represent 10–20% of some AI ETFs. A single-stock correction can significantly impact the fund.
Valuation: AI companies traded at elevated P/E multiples through 2024–2025. Thematic sectors can undergo sharp de-rating if growth disappoints.
Theme timing: Thematic ETFs often see inflows near peaks of excitement. Buying when AI is dominating headlines may mean buying at elevated prices.
AI ETFs are a thematic bet — see semiconductor ETFs for a related thematic fund capturing the chip supply chain powering AI.

Thematic ETFs carry higher volatility than index funds — see investment strategies for when thematic exposure makes sense in a portfolio.
