Best AI ETFs in 2026: BOTZ, ARKQ, AIQ and More — Ranked by Performance
— 7 min read — AI Investing
AI is the biggest investing trend of the decade. But not all AI ETFs are created equal — some chase robotics hardware, others bet on pure software, and a few swing for disruptive moonshots. Here's the full breakdown of the top AI ETFs in 2026, ranked and explained.
BOTZ — Global X Robotics & Artificial Intelligence ETF
BOTZ is the most well-known AI and robotics ETF, with over $2B in assets. It holds ~40 companies across industrial robots, autonomous systems, and AI chipmakers. Top holdings include NVIDIA, Keyence, Intuitive Surgical, and Fanuc. BOTZ is passive — it tracks an index — which keeps the expense ratio at 0.68%. It's a solid foundation for AI exposure without betting on a single stock or active manager. Performance has been strong since 2023 as the AI buildout accelerated.
ARKQ — ARK Autonomous Technology & Robotics ETF
ARKQ is Cathie Wood's robotics and AI fund. It holds fewer names (~35) with higher conviction bets: Tesla, Trimble, Kratos Defense, and UiPath. The active approach means higher fees (0.75%) and higher volatility. ARKQ's thesis is about AI-driven business model disruption — autonomous vehicles, drones, 3D printing. It's performed better than ARKK since 2024 as its industrial AI angle proved more grounded than pure speculation.
AIQ — Global X Artificial Intelligence & Technology ETF
AIQ is a broader AI ETF that includes not just robotics companies but also the AI platform players: NVIDIA, Alphabet, Microsoft, Meta. This makes it more correlated with large-cap tech than BOTZ. Expense ratio is 0.68%. AIQ tends to outperform in pure AI software rallies (e.g., post-ChatGPT) but underperforms in robotics-specific runs. Think of it as the 'everything AI' fund.
ROBO — ROBO Global Robotics and Automation Index ETF
ROBO is the OG robotics ETF — launched in 2013, long before AI was cool. It holds 80+ companies equally weighted, which makes it more diversified than BOTZ but also dilutes the AI-specific upside. Expense ratio is 0.95% — the most expensive on this list. ROBO's broad equal-weight approach means no single company dominates, but it also means limited exposure to the NVIDIA mega-cap AI wave.
QTUM — Defiance Quantum ETF
QTUM is an underappreciated pick for AI bulls. It targets quantum computing, AI, and machine learning companies — a forward-looking mandate that catches companies building tomorrow's AI infrastructure. Holdings include IBM Quantum, IonQ, and AI semiconductor companies. Lower AUM (~$400M) means less liquidity, but for investors who believe quantum AI is the next wave, QTUM offers differentiated exposure.
How to choose the right AI ETF for you
If you want passive, diversified AI hardware exposure: BOTZ. If you want a broad AI platform bet including big tech: AIQ. If you want active, high-conviction AI disruption: ARKQ. If you want pure speculation on next-gen AI infrastructure: QTUM. Most investors are better served by layering one of these into a core QQQ or SPY position rather than going all-in on a single thematic ETF. AI ETFs are volatile — size the position accordingly.
