Bitcoin ETFs Surge to $2.4B Inflows, Largest Weekly Total Since October 2025
The U.S. spot Bitcoin ETFs have seen significant growth in recent weeks, recording $2.4 billion in net inflows last week. This is the largest weekly inflow since October 2025 and marks a turning point for cumulative flows this year, which had previously been in negative territory.
BlackRock's IBIT led the charge with $1.2 billion in inflows, followed closely by Fidelity's FBTC with $701.7 million. ARK Invest and 21Shares' ARKB also attracted substantial investment, bringing in $294.7 million each.
The trend is not limited to Bitcoin, as spot Ether ETFs rebounded from net outflows a week earlier to record $689.9 million in net inflows. Spot Solana and XRP ETFs also saw significant growth, with the former reaching an all-time high of $1.5 billion in total net assets.
Monday, September 21, was particularly notable, with spot Bitcoin ETFs drawing a massive $999 million in inflows, setting the stage for the week's overall performance.
