Artificial intelligence has moved from theme to driver across public markets. Picking single winners is a tough game: leadership rotates between software and chips, competitive edges fade, and many leaders already trade at demanding valuations. For most investors, an ETF sleeve is the cleaner way to participate. It spreads exposure across the AI value chain, reduces single-name risk, and makes it easier to manage concentration, costs, and overlap with existing holdings. Much of the recent leadership also reflects an ongoing AI capex boom that continues to reshape chips and infrastructure.

This guide breaks down the most liquid and investable AI ETFs, explains how they differ on focus, concentration, and fees, and shows portfolio builds that add real diversification while avoiding hidden overlap.

A simple classification of AI ETFs

The AI value chain breaks into three investable layers. The ETFs highlighted below are approved by 8FIGURES AI.

1) “Pure-play” AI funds (software, data, platforms)

These are the most direct way to own AI monetization in software and services—model providers, analytics, data infrastructure, and AI-enabled applications.

Notable ETFs in this category:

  • Global X Artificial Intelligence & Technology (AIQ). Broad, global exposure to AI and big data via the Indxx Artificial Intelligence & Big Data Index; 0.68% expense ratio and about $6.83B AUM (Oct 24, 2025) support deep liquidity. Typical top holdings span U.S. megacaps (Alphabet, Apple, Broadcom) plus non-U.S. leaders (TSMC, Samsung), giving genuine global reach.5
  • iShares Future AI & Tech (ARTY). Tracks the Morningstar Global Artificial Intelligence Select Index; 0.47% expense ratio with a more concentrated portfolio than AIQ (roughly ~49 holdings on the latest fact sheet). Useful when you want a tighter list of global AI innovators and strong NYSE Arca liquidity.1
  • WisdomTree Artificial Intelligence & Innovation (WTAI). Broader “AI + innovation” basket that still centers on AI commercialization; 0.45% expense ratio, ~$443M AUM, and ~70 holdings (Oct 24, 2025). Listed on Cboe; a good fit when you prefer diversification and established secondary-market trading over a very narrow gen-AI sleeve.9

Investor angle: Own a diversified basket of companies that build and monetize AI software across many sectors, so you participate in the theme even if any one model or vendor falls behind. This gives you broad upside to AI adoption while reducing single-name risk and the need to pick a winner.

2) Applied AI & robotics (where code meets the physical world)

These funds emphasize robotics, machine vision, surgical systems, drones, and autonomous platforms, benefiting both from AI adoption and real-economy capex (reshoring, logistics automation, aging demographics).

  • Global X Robotics & AI (BOTZ). Specialized robotics/automation exposure tracking the Indxx Global Robotics & AI Thematic Index; 0.68% expense ratio and ~$3.19B AUM (Oct 24, 2025). Top holdings commonly include NVIDIA, ABB, Fanuc, Keyence, and Intuitive Surgical—expect higher top-10 concentration.6
  • ROBO Global Robotics & Automation (ROBO). A pioneer tracking the ROBO Global Robotics & Automation Index with a tiered equal-weight approach to temper single-name risk; 0.95% expense ratio. Useful if you want breadth across enablers and appliers rather than a cap-weighted tilt to the largest names.3
  • First Trust Nasdaq AI & Robotics (ROBT). Rules-based exposure to AI enablers and appliers via the Nasdaq CTA Artificial Intelligence & Robotics Index; 0.65% expense ratio and quarterly rebalances per methodology. A middle ground on concentration between cap-weighted and equal-weighted approaches.4

Investor angle: Capture AI as it turns into factory lines, warehouses, and operating rooms—drivers that don’t always move with software cycles.

3) “Picks & shovels” (semiconductors and compute infrastructure)

No matter who wins the model wars, everyone needs more compute. Semi ETFs are the cleanest way to express that view —higher beta, but tightly linked to the AI build-out.

  • VanEck Semiconductor (SMH). Concentrated mega-cap chip exposure (e.g., NVIDIA, TSMC, Broadcom, ASML); 0.35% expense ratio and ~$34.87B AUM (Oct 24, 2025). Expect heavy top-10 weights, efficient liquidity with sharper drawdowns when leaders correct.8
  • iShares Semiconductor (SOXX). Broader, rules-based exposure to U.S.-listed semis; 0.35% expense ratio with deep liquidity and a long record. Sector split typically spans semis and semi-equipment.2
  • SPDR S&P Semiconductor (XSD). Equal-weight alternative tracking the S&P Semiconductor Select Industry Index; 0.35% expense ratio and ~$1.78B AUM (Oct 23, 2025). Reduces single-name concentration and pushes more exposure down the cap spectrum; rebalanced quarterly under a modified equal-weight methodology.7

Investor angle: Own the compute backbone that powers every AI workload, while using XSD to tame single-name risk that can build up in cap-weighted funds.

ETF characteristics that actually matter

Liquidity and cost. The funds above are widely traded, typically charging in the 0.35%–0.95% range. For long holds, small fee differences compound, for tactical sleeves, spreads and volume matter just as much.

Concentration. Check the top-10 weight. BOTZ and SMH can be top-heavy, which is great when leaders run sharper on drawdowns. ROBO and XSD spread risk more evenly by design.

Methodology. Cap-weighted products lean into winners (and concentration). Tiered or equal-weight approaches trade some momentum for breadth. Read the index summary before assuming two “robotics” or two “semiconductor” funds will behave the same.

What recent cycles imply: In 2023–2025, software/platform and semiconductor baskets tended to lead, reflecting rapid model rollouts and data-center buildouts. Applied AI/robotics lagged at times as factory and hospital deployments moved more slowly. When industrial capex improves, leadership can rotate, so the diversification benefit comes from mixing these categories, not stacking look-alikes. Past performance does not guarantee future results.

Portfolio comparison in practice

Pure-play AI (AIQ/ARTY/WTAI) tilts toward software/platform leaders, U.S. megacaps plus select non-U.S. names, giving you direct participation in AI monetization. Overlap among these funds can be meaningful, pairing two similar baskets doesn’t always improve diversification.

Applied AI & robotics (BOTZ/ROBO/ROBT) brings Industrials and Healthcare into the mix, intuitive diversifiers inside the AI them, with BOTZ notably more concentrated than ROBO.

Semis (SMH/SOXX/XSD) are the most cyclical and the most directly tied to the data-center buildout. Adding XSD to a cap-weighted core helps reduce reliance on a handful of megacaps.

Takeaway: Diversification within AI comes from mixing categories, not from stacking two similar “pure-play” funds, and within semis by pairing cap-weighted (SMH/SOXX) with equal-weight (XSD).

Building an optimal sleeve: combinations that make sense

Hidden risks first: overlap and look-through exposure

Before combining funds, pull each holdings file. Buying two similar baskets can double exposure to the same megacaps. If you already hold NVDA directly, add up the look-through weight across every ETF. Accidental concentration is the most common mistake.

Strategy 1 — Core–satellite (broad, then targeted)

  • Core (60–80%): AIQ (or ARTY) for diversified software/data exposure.
  • Satellite 1 (10–20%): BOTZ (or ROBO/ROBT) for industrial & medical automation.
  • Satellite 2 (10–20%): SMH (or SOXX) plus a smaller sleeve of XSD to reduce single-name concentration in the chips bucket.

This captures software monetization, real-world deployment, and chips—three distinct levers that rarely peak in unison, while XSD smooths the cap-weighted concentration.

Strategy 2 — Balanced “software + hardware”

  • 50% in a software-tilted fund (ARTY or AIQ) with WTAI as an optional broader AI+innovation tilt,
  • 50% in applied/hardware (ROBO or BOTZ), and consider XSD as a small overlay if you want equal-weight behavior in semis without adding a separate satellite.

Set explicit rebalance rules (e.g., quarterly with drift bands) so you’re not trading headlines. Match fees and liquidity to your holding period.

To tailor these builds to your portfolio, run them through 8FIGURES for a quick diagnostic on positions, diversification, and next rebalancing steps.

Conclusion

There isn’t a single “best” AI ETF because AI isn’t a single market. Software and data platforms, applied robotics, and semiconductors move on different clocks and respond to different drivers. Building across the stack, rather than doubling up on look-alike funds, gives you cleaner exposure and fewer blind spots.

In practice, that means pairing a diversified software fund with targeted satellites in robotics and chips. In this lineup, WTAI offers a broader, liquid software tilt, while XSD complements SMH/SOXX to curb single-name risk in semis. Keep concentration visible, check overlap before you add, and let a simple rebalance rule handle timing. You can track these ETFs and monitor exposure and overlap in the 8FIGURES App.
