AI ETFs Compared: Holdings, Overlap, Costs
AI ETFs promise bundled exposure to the decade’s defining technology theme — and often deliver something else: heavy overlap with what you probably already hold. The decisive question is not which AI ETF is “best”, but whether it adds any new exposure to your portfolio at all.
Here is the comparison of the relevant products — and the overlap math that should precede any purchase.
The relevant AI ETFs compared
Several products have established themselves on the European market, framing the theme more or less broadly — from a narrow AI focus to combinations with robotics and automation. Expense ratios of roughly 0.35–0.5% p.a. sit well above a world ETF (often below 0.2%):
| ETF | Focus | TER (approx.) | Character |
|---|---|---|---|
| Xtrackers Artificial Intelligence & Big Data | AI, big data, cybersecurity | around 0.35% | Patent-based selection, tech-heavy |
| WisdomTree Artificial Intelligence | Narrow AI focus incl. mid caps | around 0.4% | More specialized, higher single-stock risk |
| iShares Automation & Robotics | Robotics & automation | around 0.4% | Broader, many smaller industrials |
| Amundi MSCI Robotics & AI | Robotics + AI mixed | around 0.4% | Blended approach, medium concentration |

The underestimated point: overlap with the Nasdaq 100 and MSCI World
In their top holdings, many AI ETFs are barely distinguishable from a Nasdaq 100 ETF: Nvidia, Microsoft, Alphabet and Broadcom dominate both. If you hold a world ETF (roughly 70% US, tech heavyweights on top) or a Nasdaq 100 ETF and add an AI ETF, you mostly increase the weight of names you already own. Concretely: in a €100,000 portfolio with 80% MSCI World and 20% AI ETF, the effective positions in the big US tech names can add up to well over €25,000 — without being visible at first glance.
So before buying: check your ETF overlap — MoneyPeak’s overlap analysis computes it at single-stock level against your existing portfolio. For the names shaping the sector beyond the ETF wrapper, see the AI stocks overview.
The thematic ETF critique — and the tax side
The structural weakness of thematic ETFs is timing: they typically launch once a theme is already hot — buying in at rich valuations. Add the higher TER and the concentration. They do not work as a core holding; as a deliberately sized satellite (commonly 5–10% of the portfolio) they are defensible once overlap is checked.
For German investors, AI ETFs are taxed like other equity funds: 30% partial exemption (Teilfreistellung) on income and gains, 26.375% flat tax on the taxable remainder, and accumulating products incur the annual Vorabpauschale. The saver’s allowance of €1,000 (€2,000 for married couples) applies as usual.
Frequently asked questions
Which AI ETF is the best?
The question falls short: what matters is whether the ETF adds new exposure or merely duplicates existing tech positions. Check overlap first, then choose between a narrow AI focus (WisdomTree) and a broader approach (iShares Automation & Robotics).
How much do AI ETFs overlap with the Nasdaq 100?
Substantially: the top holdings of many AI ETFs — Nvidia, Microsoft, Broadcom, Alphabet — are also heavyweights in the Nasdaq 100 and MSCI World. Effective overlap can only be computed at single-stock level against your own portfolio.
How are AI ETFs taxed in Germany?
Like equity funds: 30% partial exemption, 26.375% flat tax including solidarity surcharge on the remainder. Accumulating funds are subject to the annual Vorabpauschale; the €1,000/€2,000 saver’s allowance remains available.
