Goldman Sachs, once a vocal critic of Bitcoin, has made a significant shift by investing heavily in Bitcoin exchange-traded funds (ETFs). According to a recent SEC filing, the investment bank now holds around $718 million in eight Bitcoin ETFs. This includes a $461 million stake in BlackRock's iShares Bitcoin Trust ETF and substantial investments in Fidelity, Grayscale, and Invesco ETFs. Since Q2 2024, Goldman Sachs has increased its Bitcoin ETF holdings by 71%. Despite past skepticism, the bank is now a major player in the crypto ETF market, also investing $22 million in Ether ETFs.
