Analysis of publicly listed funds reveals distinct strategies for OpenAI exposure, with ARK Invest maintaining the highest portfolio weights among ETFs and mutual funds. The asset manager has concentrated its artificial intelligence bets more heavily than competitors on a percentage basis. Fidelity holds the largest total dollar exposure to OpenAI by a significant margin, though this position is distributed across at least 19 separate funds. This diversified approach contrasts with ARK's higher-weight strategy, offering investors different methods to gain indirect access to the private AI company through public markets.
