US spot Bitcoin ETFs saw a significant surge in interest, recording net inflows of $998.95 million on Monday. This performance marks the strongest daily inflow for these funds since October 2025, contrasting sharply with the previous week, which saw only $6.2 million in inflows.
BlackRock’s IBIT fund led the market with $381.37 million in inflows. Other major contributors included Ark and 21Shares’ ARKB with $289.12 million, Fidelity’s FBTC with $238.84 million, Morgan Stanley’s MSBT with $61.67 million, and Bitwise’s BITB with $21.56 million.
The price increase of Bitcoin to over $86,000 pushed the asset above the estimated average holder cost basis of $81,722. According to Bloomberg Intelligence analyst James Seyffart, this shift has returned the average US spot Bitcoin ETF investor to profitability for the first time since January.
On Monday, the total trading volume for these ETFs reached approximately $4.5 billion. Since their inception, cumulative net inflows into US spot Bitcoin ETFs have hit $56.16 billion, with total assets under management currently standing at $110.14 billion, representing 6.3% of Bitcoin’s market capitalization.
