Overview
- The flow reversal began after mid‑September outflows and produced roughly $2.1–$2.3 billion of net new money from September 17 through September 22, with about $2 billion added for the week.
- A single session on September 21 saw about $999 million of net inflows to spot Bitcoin ETFs and the September 22 session added roughly $877 million combined to Bitcoin and Ether ETFs.
- BlackRock’s IBIT led the move, capturing about $1.02 billion of inflows during the multi‑day stretch and bringing total US spot Bitcoin ETF assets to roughly $110.8–$111 billion with IBIT near $67.9 billion.
- Ether ETFs also recorded consecutive large inflow days, with BlackRock’s ETHA among the top recipients and roughly $210–$270 million of inflows across the recent sessions.
- These ETF creations represent money flowing into regulated vehicles rather than direct on‑chain purchases, and because US ETFs now hold a sizable share of supply, concentrated issuer flows and macro factors like Treasury yields and Fed policy will determine whether buying pressure and price gains persist.
