The cumulative trading volume of U.S. spot crypto ETFs has surpassed $2 trillion, achieving this milestone in just 8 months since reaching $1 trillion in May 2025. This rapid growth highlights the increasing investor interest in these financial products. Bitcoin and Ethereum ETFs have seen a net inflow of $646 million, with BlackRock's IBIT commanding approximately 70% of the market share. The range of spot ETFs has expanded to include assets like SOL and XRP, with XRP-related products attracting $1.2 billion in inflows since their launch in November last year.
