U.S. spot Bitcoin exchange-traded funds recorded $31.07 million in net inflows on Sept. 28, marking the lowest daily intake of an eight-day positive streak as Bitcoin struggled to break through a key long-term supply barrier at $84,000.
ETF Inflows Fall 97% From Peak Despite Record Week
While the $31.07 million net intake extended the positive streak for U.S. spot Bitcoin ETFs to eight consecutive sessions, it marked a 97% decline from Sept. 21, when daily inflows approached $1 billion. Despite the daily slowdown, broader weekly figures remain robust. The funds attracted $2.4 billion last week—their largest weekly inflow of 2026 and the highest since October 2025.
That weekly influx flipped year-to-date flows back into positive territory at $1.01 billion, reversing a deficit that reached $5.8 billion in July. Month-to-date inflows reached $2.73 billion, according to data from SoSoValue.
During Monday's session, BlackRock's iShares Bitcoin Trust (IBIT) led with $54.84 million in inflows, accumulating roughly 657 BTC and pushing its total holdings above 800,000 BTC for the first time since May 26. Grayscale's Bitcoin Mini Trust (BTC) added $10.32 million. Meanwhile, Fidelity's Wise Origin Bitcoin Fund (FBTC) posted $10.90 million in net outflows, and Grayscale's GBTC lost $23.19 million. All other spot products saw zero net flows.
$84,000 Supply Cluster Tests Institutional Demand
The drop in institutional buying comes as Bitcoin trades near $84,000, retreating from last week's peak above $87,000. According to analytics firm Glassnode, long-term holder supply is heavily concentrated between $84,000 and $85,000—representing a larger cost-basis concentration than any other price level.
At current prices, Monday's $31.07 million net intake absorbed fewer than 400 BTC, compared to more than 11,000 BTC absorbed during the near-$1 billion inflow peak. Last week, ETF inflows absorbed persistent profit-taking and selling by perpetual-futures traders to support a 4% gain. However, as spot ETF inflows slow, diminished marginal institutional buying leaves fewer funds to absorb overhead supply.
Key Takeaways
- $31.07 Million Inflows: Lowest intake of the eight-day streak, down 97% from the Sept. 21 peak.
- BlackRock IBIT Holdings: Added $54.84 million (657 BTC), taking holdings past 800,000 BTC for the first time since May 26.
- $84,000 Resistance: Glassnode identifies $84,000–$85,000 as the dense concentration of long-term holder supply.
Why It Matters
The decline in daily ETF accumulation highlights how dependent Bitcoin's recovery has been on steady institutional buying power. With long-term holders holding massive inventory between $84,000 and $85,000, BTC needs active institutional absorption to clear breakeven sell orders. If ETF inflows stall further or flip to negative, Bitcoin could face renewed downside pressure or extended sideways consolidation.
