Key Takeaways
  • • U.S. spot Bitcoin ETFs took in about $549.76 million in net inflows across Monday and Tuesday, per SoSoValue data, reversing the roughly $229 million withdrawn in the prior week.
  • • Monday contributed $526.60 million of the total, while Tuesday added only $23.16 million, so the two-day gain was driven almost entirely by a single session.
  • • BlackRock's IBIT led Tuesday with $29.86 million in inflows, while Fidelity's FBTC added $3.58 million and Bitwise's BITB posted $10.29 million in outflows.
  • • Ether ETFs posted $129.41 million in net outflows over the same two sessions, extending their October redemption pattern and following roughly $320 million in outflows the prior week.
Summary
U.S. spot Bitcoin ETFs collected about $549.76 million in net inflows across Monday and Tuesday, according to SoSoValue data cited in the report. Monday accounted for $526.60 million of that total, with Tuesday contributing $23.16 million. The two-day figure more than offset the roughly $229 million that flowed out of Bitcoin funds during the previous week, marking a sharp reversal in short-term direction.

On Tuesday, BlackRock's IBIT attracted $29.86 million and Fidelity's FBTC added $3.58 million. Bitwise's BITB partially offset those gains with $10.29 million in net outflows. Tuesday's trading value reached $1.92 billion, and total net assets closed near $106.28 billion. The report notes that inflows slowed sharply from Monday's pace, and that October has been volatile for Bitcoin ETF flows, with daily reversals shaping the short-term picture.

Ether ETFs moved in the opposite direction. Tuesday saw $26.13 million in net outflows, bringing the combined two-day total to $129.41 million. BlackRock's ETHA lost $33.02 million, while Fidelity's FETH gained $3.63 million and Grayscale's Ether Mini Trust added $3.25 million. Ether products lost about $320 million over the prior week, so the divergence between Bitcoin and Ether fund flows has persisted.

The report cautions that two positive sessions do not by themselves establish a sustained institutional trend. Weekly momentum for Bitcoin ETFs is currently positive, but its durability will depend on whether subsequent sessions continue to attract net capital.
