Bitcoin ETF Inflows Rise as BTC Battles Key $79.5K Resistance

Key Insights:

• Bitcoin ETF demand strengthened across the broader six-week fund-flow window.
• Crypto funds recorded $6.8 billion in inflows over six consecutive weeks.
• Bitcoin held near $78,000, while $79,500 remained immediate resistance.

Bitcoin exchange-traded fund demand stayed firm across a broader six-week window. Meanwhile, Bitcoin held near $78,000 on Sept. 15, 2026. The setup kept $79,500 as the immediate level separating consolidation from another test of $80,000.

The Kobeissi Letter said crypto exchange-traded funds attracted $1.3 billion last week. It said total inflows reached $6.8 billion across six consecutive weeks. The same research account put BlackRock’s iShares Bitcoin Trust inflows at $3.4 billion during that period.

Bitcoin ETF Flows Diverge from Daily U.S. Spot Data

Farside Investors showed a weaker short-term picture for U.S. spot Bitcoin products. Its dataset recorded net outflows on four sessions between Sept. 8 and Sept. 11. Those sessions produced combined outflows of about $462.7 million.

Farside recorded another $9.7 million inflow on Sept. 14, based on available fund data. Cumulative U.S. spot Bitcoin ETF flows totaled nearly $55.23 billion, as shown in the table. The difference shows why weekly crypto-fund totals cannot be treated as spot Bitcoin-only flows.
