An artificial intelligence ETF is a basket of stocks picked by an index rule, not by a panel of AI experts. The index decides what counts as AI exposure, and the rules are looser than most buyers realize. The name sells the theme. The index rule defines it.

That is why two AI ETFs can look nothing alike. One weights NVDA and MSFT heavily. Another is full of industrial robotics firms you have never heard of. Both can legally call themselves AI funds, and both do. Marketing pages will not tell you this. The methodology PDF will.

TrueAI scores any AI ETF on its holdings' real AI substance, using filing data instead of marketing copy. The free scorecard covers the top 10 holdings; $15/mo unlocks the full ranking and historical scores.

Before buying, read the index methodology on the issuer's site. If you cannot explain in one sentence why each top holding is an AI company, keep looking. Two minutes of reading beats a year of hoping.

The index rule is the product. Read it like one.
