U.S. spot Bitcoin exchange-traded funds (ETFs) are approaching a cumulative trading volume of $1 trillion in less than 18 months since their launch, marking a rapid growth in market activity. In May 2025, these ETFs experienced nearly $6 billion in net inflows, representing one of their strongest months to date. Bitcoin's price surged 11.1% in May, reaching an all-time high of $112,000, with support levels between $94,000 and $97,000. ETF inflows for Bitcoin in May increased by 121% to $5.5 billion, surpassing gold ETFs, which saw inflows decline to $1.5 billion. On a single day recently, U.S. spot Bitcoin ETFs purchased $431.2 million worth of Bitcoin. Despite this growth, Ethereum derivatives have seen higher daily trading volumes, surpassing Bitcoin with $110 billion in daily trades. The rise of Bitcoin ETFs reflects growing institutional interest and Wall Street's increasing allocation to cryptocurrency assets.
