Investors poured $471 million into US spot Bitcoin ETFs on April 6, the largest single-day gain since late February, according to Farside Investors.
BlackRock’s IBIT and Fidelity’s FBTC topped the inflows, followed by ARK Invest and 21Shares’ ARKB. Other competing funds posted smaller gains.
IBIT pulled in roughly $182 million, and FBTC added approximately $147 million. Together, the two products made up about $329 million of the day’s total inflows, a ratio consistent with their dominance of the spot Bitcoin ETF category since these funds launched in January 2024.
The inflows came during a period of sharp price swings. Bitcoin declined as much as 45% from its October 2025 peak. At press time, the digital asset was trading at $68,714, per CoinGecko.
US spot Bitcoin ETFs now hold approximately $90 billion in total assets, led by IBIT with $54.5 billion, or nearly 60% of the market. Cumulative net inflows have reached an estimated $56 billion.
The first quarter of 2026 was uneven. January and February saw roughly $1.8 billion in net outflows as concerns about Federal Reserve policy and sticky inflation prints weighed on risk sentiment. March brought a partial turnaround, with $1.3 billion flowing back into Bitcoin ETFs as prices stabilized.
Despite renewed interest in Bitcoin ETFs, experts caution that the trend could shift rapidly if inflation surprises to the upside. Market attention is focused on Friday’s March CPI release, along with February’s core PCE report released Thursday, April 9.
