BlackRock’s spot Bitcoin ETF (IBIT) has surpassed the firm’s flagship S&P 500 ETF (IVV) in annual fee revenue, despite being much smaller in total assets. IBIT, with an expense ratio of 0.25% and about$75 billion in assets under management, has generated$187.2 million in annual fees—roughly$100,000 more than IVV, which manages$624 billion but charges a much lower 0.03% fee.

Bitcoin ETFs remain controversial due to regulatory uncertainties and volatility risks, challenging investor trust and adoption.
