How it works
WTAI is an index fund. Rather than picking stocks, it aims to match the WisdomTree Artificial Intelligence & Innovation Index, before fees. WisdomTree designs the index and also owns the fund's adviser, WisdomTree Asset Management. The index draws on exchange-listed companies in dozens of developed and emerging countries. To qualify, a company must earn at least 50% of its revenue from one of four areas: AI software, semiconductors and chip equipment, other AI hardware, or 'innovative' technology products and services. It also needs a market value of at least $100 million and median daily trading above $1 million in each of the prior three months. WisdomTree expects about half of the index weight to come from the three AI categories.
A WisdomTree committee oversees the rules, and the index is reconstituted and rebalanced every quarter. The fund uses representative sampling. That means it may hold a subset of the index's stocks with similar overall traits rather than every one. It must keep at least 80% of net assets in index stocks or close equivalents. Portfolio turnover was 85% in the latest prospectus, a sign the holdings change often.
As of June 30, 2026, the fund held 57 stocks, with no derivatives and 0.63% in cash. It usually pays redemptions in cash. That can force it to sell holdings and pass taxable capital gains on to shareholders.
What it really costs
- WTAI charges 0.45% a year, versus an average of 0.38% for the similar funds below (7th of 9, cheapest first).
- Using the prospectus's standard example, $10,000 invested would cost about $46 in the first year and $567 over 10 years (assuming a 5% annual return).
| Cost of $10,000 (SEC example) | 1 yr | 3 yrs | 5 yrs | 10 yrs |
|---|---|---|---|---|
| WTAI | $46 | $144 | $252 | $567 |
In a retirement portfolio
WTAI is a narrow, volatile theme fund that fell nearly half its value in 2022, so it fits as a small add-on rather than a foundation.
WTAI could add focused exposure to AI chipmakers and software companies, but its swings are larger than the broad stock market's. It launched in December 2021, so it has no record from the 2008 or 2020 crashes. In the 2022 bear market it fell 44.5%, and 2022 was its worst calendar year, at −42.4%. Its deepest drop, 45.9% from December 27, 2021 to October 14, 2022, took about 33 months to recover. Anyone forced to sell or draw cash during that stretch would have locked in heavy losses. Income is small: the trailing yield was 1.37% as of October 27, 2026, paid once a year. Costs are 0.45% a year, or $46 in the first year on $10,000 under the SEC's standard example. Past results don't predict future returns, and a plan should look at the whole portfolio, not one fund.
Who it may suit — and who should look elsewhere
May suit
- Investors wanting a global AI slice that adds Korean, Japanese and Taiwanese chipmakers such as Samsung, SK Hynix and Kioxia alongside Nvidia.
- People who can sit through deep drops: WTAI fell 45.9% from December 2021 to October 2022 and took about 33 months to recover.
- Those who prefer a rules-based index, with a 50% AI-revenue test and quarterly rebalancing, over a manager's stock picks.
Look elsewhere if
- Retirees who may need to sell in a downturn: one-year volatility was 39.5% as of October 27, 2026, and beta was 2.37 (about 2.4 times the market's moves).
- Cost-focused investors: the 0.45% fee ranks 7th of 9 among similar funds, against 0.20% for QQQ and 0.08% for XLK.
- Anyone seeking steady income: the trailing yield was 1.37% as of October 27, 2026, paid only once a year.

Questions investors ask
Is WTAI good for retirement?
WTAI works more like a small, higher-risk add-on than a core retirement holding. It fell 44.5% in the 2022 bear market. Its deepest drop, 45.9%, took about 33 months to recover, finishing on July 17, 2025. Its trailing yield was 1.37% as of October 27, 2026, paid once a year, so it adds little income. Investors who may need to sell shares in a bad year face real timing risk with this fund.
What stocks are in WTAI?
As of June 30, 2026, WTAI held 57 stocks, and the top ten made up 37.1% of assets. The largest were Micron Technology (5.2%), Samsung Electronics (4.4%), Sandisk (4.0%), Kioxia (4.0%) and Nvidia (3.8%). Next came SK Square, Amazon, Alphabet, Taiwan Semiconductor and Palo Alto Networks. About 75% was in US companies, 10.3% in South Korea, 6.0% in Japan and 4.9% in Taiwan.
WTAI vs QQQ: what's the difference?
QQQ is far larger and cheaper. WTAI is a narrower, global AI fund. About 42% of their holdings overlap, based on the latest N-PORT reports. QQQ charges 0.20% a year against WTAI's 0.45%. As of June 30, 2026, QQQ had about $490 billion in net assets and WTAI had $669 million. WTAI's price return was 24.9% over one year and 35.1% a year over three years as of October 27, 2026. QQQ's were 10.8% and 26.2% as of October 30, 2026.
Does WTAI pay dividends?
Yes, but only once a year, and the amount is small. The trailing 12-month yield was 1.37% as of October 27, 2026, or about $0.53 per share. The fund aims for exposure to AI-related companies, not income. It usually pays redemptions in cash, and its turnover was 85%. Both can lead to capital gains distributions, which may be taxable in a regular brokerage account.
What is WTAI's expense ratio?
WTAI's expense ratio is 0.45% a year, with no fee waiver, according to its prospectus filed October 28, 2026. The SEC's standard example assumes $10,000 invested, a 5% annual return and shares sold at the end of each period. On that basis, costs would total about $46 after one year, $144 after three, $252 after five and $567 after ten. That is above the 0.38% average of similar funds. Xtrackers' XAIX charges 0.35% and TCW's AIFD charges 0.75%.
