U.S. spot Bitcoin ETFs have attracted roughly $2.65 billion across five consecutive positive sessions, putting them on track for their strongest weekly performance since October 2025. Bitcoin, meanwhile, recently climbed above $87,000, its highest level in eight months, before pulling back.
ETF Inflows Accelerate
The strongest session came on September 21, when spot Bitcoin ETFs recorded approximately $999 million in net inflows.
- BlackRock IBIT: +$381.4M
- ARK 21Shares ARKB: +$289.1M
- Fidelity FBTC: +$238.8M
- Morgan Stanley MSBT: +$61.7M
Buying continued with $714.7 million on September 22 and $347 million on September 23.
| Metric | August surge | Current streak |
| ETF inflows | ~$1.9B | ~$2.65B |
| Largest daily inflow | $517M | ~$999M |
| BTC price | ~$77K–$78K | ~$85K–$87K |
The current streak has already surpassed August's roughly $1.9 billion inflow wave.
Bitcoin Technical Levels
Bitcoin broke through the $80,000 area before reaching an eight-month high above $87,000.
Key levels to watch:
- Support: $80,000–$82,000
- Resistance: around $90,000
- Estimated ETF cost basis: ~$81,700
Strong ETF demand could provide an important source of spot-market support while macro conditions remain restrictive.
The main headwinds remain higher U.S. interest rates, elevated Treasury yields and uncertainty surrounding Iran. With roughly $2.65 billion flowing into Bitcoin ETFs in five sessions, the immediate levels are clear: $90,000 is the key upside barrier, while $80,000–$82,000 is the main support zone. A move outside this range would provide the next major signal for Bitcoin's direction.
