TCAI vs WTAI

TCAIBTortoise AI Infrastructure ETF

WTAIAWisdomTree Artificial Intelligence and Innovation Fund

In short

TCAI A stock picker's run at the AI buildout. TCAI is actively managed with no index to follow, aiming at the companies that supply AI infrastructure, and it prices right at the middle of its small niche.

WTAI Most AI ETFs are a repackaged bet on the same few mega caps. WTAI spreads roughly 90 global names across the whole stack (software, chips, the hardware underneath) at close-to-equal weights, for 0.45% a year.

Stated mandate

TCAI The Fund invests with an emphasis on companies involved in AI infrastructure. It is actively managed and does not seek to track an index.

WTAI The fund seeks to track, before fees and expenses, the price and yield performance of the WisdomTree Artificial Intelligence & Innovation Index, whose constituents are companies primarily involved in the AI and innovation investment theme.

Why people hold it

• TCAI No index, no rulebook. The managers pick the AI infrastructure names themselves, so the portfolio can shift as the buildout does rather than wait for a quarterly reconstitution.
• At 0.65% a year it lands on the median fee for its AI infrastructure cohort, and under the 0.69% charged by Defiance's AIPO, despite being run actively.
• In a crowded new corner (seven funds chasing AI infrastructure), this one grades out in the upper half on our review.
• Liquidity is a bright spot: it changes hands often enough that getting in and out is one of the smoother parts of owning it, unusual for a fund this new.

• WTAI Charges 0.45% a year, below the median fee in the AI thematic crowd. In a theme this packed, cost is the part you actually control.
• Weights land close to equal across roughly 90 stocks, so no single mega cap runs the portfolio the way it does in cap-weighted AI funds.wisdomtree.com
• The index reaches across AI software, semiconductors and the other hardware AI runs on, and it can hold listings outside the US, not just a Nasdaq tech slice.wisdomtree.com
• One of the stronger builds in a crowded AI cohort: broad rules-based portfolio, low fee, no structural quirks in the wrapper.

Worth knowing

• TCAI Launched in August 2025, so the track record is thin. There is not yet enough history to judge how it behaves through a full market cycle.
• Active costs more here. Index-run peers in the same niche, Franklin's XDAT at 0.50% and ProShares' DAT at 0.58%, undercut it.
• Distributions come once or twice a year, and the fund is still mid-sized rather than a giant. This is a growth-theme holding, not an income line item.

• WTAI Still one theme. Tech-heavy and prone to bigger swings than a broad-market fund. Owning 90 names dilutes single-stock risk, not AI risk.wisdomtree.com
• Near-equal weighting cuts both ways: when one giant is carrying the theme, spread-out weights keep this fund from leaning into it.wisdomtree.com
• The roster resets at scheduled rebalances rather than continuously, so index changes arrive in batches and bring turnover with them.wisdomtree.com
