In 2025, exchange-traded funds (ETFBitcoin-based exchanges have seen historic inflows, sharp declines, and significant rotations. This year has demonstrated both the market’s maturity and the growing sophistication of investors in ETF in anticipation of 2026.
January started with a steady inflow of funds into bitcoin ETF: $1,96 billion on January 17 and $1,76 billion on January 24, bringing net assets to over $120 billion at the start of the year. Trading volumes were high but orderly.
February brought the first shock. A severe risk reversal triggered weeks of sustained outflows, including a staggering $2,61 billion withdrawal at the end of February. Despite this, total assets remained resilient, exceeding $95 billion, highlighting how quickly ETF have become established in institutional portfolios.
March and April brought stabilization. Volatility persisted, but the inflow of funds returned, culminating in an influx of $3,06 billion at the end of April. By May, the momentum had completely reversed. Bitcoin ETF demonstrated some of the highest demand in a year, including a $2,75 billion capital influx in mid-May.
