Spot Bitcoin ETFs See Third Straight Week of Inflows at $241 Million
U.S. spot bitcoin exchange-traded funds (ETFs) continued their positive momentum with $241 million in net inflows for the week ending October 2, 2026. This marks the third straight week of inflows, bringing cumulative net inflows since their January 2024 launch to $57.8 billion. BlackRock’s iShares Bitcoin Trust (IBIT) led the week with $450 million in inflows, while Fidelity’s Wise Origin Bitcoin Fund (FBTC) saw the largest outflow at $168 million. Total net assets across spot bitcoin ETFs now stand at approximately $108.9 billion, representing about 6.4% of bitcoin’s market capitalization.
The week’s inflows were significantly lower than the previous week’s $2.4 billion, reflecting a slower pace. Meanwhile, ether ETFs experienced $138 million in net outflows, reversing the prior week’s $690 million inflow. Other smaller products like Zcash ETFs recorded their first weekly outflow, while Solana and XRP ETFs continued their inflow streaks.
After a challenging first half of 2026, spot bitcoin ETFs rebounded in August and September, recovering from a $5.8 billion net outflow deficit by mid-July. Year-to-date net inflows are now approximately $1.2 billion, with bitcoin trading near $86,200 in early October. The concentration of inflows in IBIT highlights BlackRock’s dominant position, while the divergence between bitcoin and ether ETFs suggests investors view ether as a more tactical position.
Looking ahead, the key question is whether weekly flows can stabilize above zero without the large single-week surges that characterized September’s rebound. This stability will be crucial for sustaining the recent recovery in spot bitcoin ETF inflows.
