Bitcoin ETF Inflows Summary

Key Figures and Timeline

Spot Bitcoin ETFs attracted approximately $2.4 billion in net inflows during the week of September 21-25, 2026, marking their strongest weekly performance of the year. However, daily inflows showed a concerning downward trend:

• September 21: $999 million
• September 22: $715 million
• September 23: $347 million
• September 24: $191 million
• September 25: $134 million

The first two days accounted for roughly 72% of the week's total inflows, while the final day represented just 13% of the initial day's figure.

Market Context

Bitcoin traded near $84,000 as of September 26, up 3.3% for the week but down approximately 4% year-to-date in 2026 and 23% year-over-year. The cryptocurrency's market dominance has fallen below 60%.

Bitcoin ETFs hold $108.4 billion in total assets, with year-to-date 2026 inflows of only $320 million—a modest gain after the funds previously posted $1.07 billion in net outflows through September 9.

Market Implications

The weekly surge appears to be a recovery following significant outflows of $746 million on September 15-16, triggered by Senate legislative setbacks and market turbulence. However, the declining daily momentum suggests cooling demand rather than sustained institutional enthusiasm.

Analysts note the CBOE Volatility Index dropped from 17.7 to 14.2 during this period, indicating calmer market conditions. Critical price levels to watch: $87,500 (upside resistance) and $81,200 (downside support). Competition from alternative cryptocurrencies continues pressuring Bitcoin's market position.
