Bitcoin Spot ETFs Attract $2.4 Billion in Inflows as Daily Momentum Slows

Spot Bitcoin exchange-traded funds pulled in $2.4 billion between September 21 and September 25, 2026, recording their highest weekly inflow total of the year. The net purchases brought total assets across the fund group to $108.4 billion, representing about 6 percent of all circulating Bitcoin.

Daily figures tapered sharply across the five-day run. The week opened on September 21 with $999 million in net share creations and dropped to $715 million on September 22. Capital arrivals slowed further to $347 million on September 23, $191 million on September 24, and reached $134 million on September 25. The initial two sessions generated roughly 72 percent of the aggregate weekly intake, while Friday accounted for just 13 percent of Monday’s volume.

Daily Allocations Taper After Front-Loaded Start

Data from SoSoValue shows the deceleration occurred as Bitcoin traded near $84,000 on September 26, up 3.3 percent over the week but down 0.9 percent on the day. The token remains roughly 4 percent lower in 2026 and sits 23 percent below its price from the same period in 2025.

Authorized participants create and redeem ETF shares by exchanging cash or underlying tokens. Daily totals net these creations against redemptions across all issuers, meaning smaller net numbers can reflect either light aggregate turnover or heavy creations at one issuer cancelled out by withdrawals at another. Hedge fund activity also shapes the volume. Funds running basis trades buy spot ETF shares while simultaneously shorting Bitcoin futures to capture yield spreads, generating share creation without taking directional long exposure on the underlying asset.

Market Stability and Asset Dominance Shifts

Macro volatility eased during the same window. The CBOE Volatility Index declined from 17.7 on September 16 to 14.2 on September 22, pointing to reduced hedging pressure across equity and asset markets rather than forced liquidations.
