The best AI ETF expense ratio comparison starts with an uncomfortable fact: AI fund fees range from 0.18% to nearly 1%. On a $50,000 position held for a decade, that gap costs thousands. Fees are the one return component you control completely.

Compare IRBO at 0.47% against ROBO at 0.95% and BOTZ at 0.68%. Same theme, very different toll. The question is whether the pricier fund's holdings justify the spread.
