U.S. spot crypto ETFs reached a cumulative trading volume of over $2 trillion as of January 2, 2026, doubling from $1 trillion in just eight months. The rapid growth reflects increasing institutional interest, bolstered by new ETFs tracking various cryptocurrencies like Solana and XRP. BlackRock's Bitcoin ETF dominates the market with a 70% share.

U.S. spot bitcoin ETFs recorded $1.42 billion in inflows last week, the highest since October. BlackRock’s IBIT led with $1.03 billion, reflecting strong institutional interest despite short-term volatility in bitcoin's price. Ethereum ETFs also saw significant inflows of $479 million.

BlackRock's iShares Bitcoin Trust (IBIT) experienced its largest outflow ever, with $523 million leaving the fund in a single day. This trend follows a decline in bitcoin's price and reflects institutional investors adjusting their portfolios amid market uncertainty. Overall, IBIT has seen $1.43 billion in outflows over the past five days.

Bitcoin's volatility has reached a 20-month low, alongside a significant drop in monthly transactions, marking the lowest activity since October 2023. Despite this decline, U.S. spot Bitcoin ETFs have seen record cumulative inflows, approaching $50 billion, indicating strong institutional demand for BTC.
