Key Insights
- Bitcoin ETF inflows topped $1.7 billion across two sessions.
- BTC price recovered above the average ETF investor cost basis.
- Four consecutive inflow sessions reversed mid-September fund withdrawals.
U.S. spot Bitcoin ETF inflows exceeded $1.7 billion across two sessions as BTC price held above $86,000 and institutional demand recovered from mid-September withdrawals.
SoSoValue-based data showed the funds attracted $998.95 million on Sept. 21 and another $714.75 million on Sept. 22. That brought the two-session total to approximately $1.714 billion.
The recovery also pushed Bitcoin above an estimated average acquisition cost for U.S. spot ETF investors. Bloomberg Intelligence analyst James Seyffart placed that cost basis around $81,722 per BTC.
Bitcoin ETF Inflows Accelerate as BTC Price Recovers
SoSoValue data showed spot Bitcoin funds attracted about $715 million on Sept. 22. That followed roughly $999 million on Sept. 21, the strongest daily intake of 2026.
The two-day total exceeded $1.7 billion. Total net assets across U.S. spot Bitcoin ETFs reached roughly $111 billion on Tuesday.
BlackRock’s iShares product remained the largest U.S. spot Bitcoin fund by assets. BlackRock listed IBIT assets near $67.9 billion in its latest product table.
That scale means missing issuer data can materially distort early daily flow totals. It also explains differences between preliminary fund-level and later aggregate readings.
Glassnode’s ETF balance dataset showed IBIT holding more Bitcoin than any competing U.S. spot product. Fidelity’s FBTC ranked second among the large funds.
The concentration makes BlackRock and Fidelity central to daily flow direction. Large subscriptions or redemptions can dominate aggregate Bitcoin ETF readings.
Farside Investors showed Fidelity’s Wise Origin Bitcoin Fund received $257.4 million on Sept. 22. Grayscale’s Bitcoin Mini Trust added $99 million.
Farside’s published table showed $364.4 million for Tuesday because BlackRock’s IBIT entry remained blank. SoSoValue’s later aggregate reflected the higher daily total.
The reversal followed two heavy redemption sessions earlier in the month. Farside recorded $450.4 million on Sept. 15 and $295.9 million on Sept. 16.
Bitcoin ETF Cost Basis Returns Below Spot Price
Bloomberg Intelligence analyst James Seyffart said average ETF holders moved back into profit on Monday. He estimated their aggregate Bitcoin cost basis at $81,722 per coin.
BTC price remained above that level through Tuesday and Wednesday. CoinGecko recorded a Sept. 22 closing price near $86,183.
Bitcoin briefly moved above $87,000 during Wednesday trading before easing. CoinGlass later showed BTC near $86,420, up about 0.9% over 24 hours.
That recovery placed Bitcoin above a resistance zone identified earlier by Glassnode. Its Sept. 9 research placed institutional break-even levels between $83,000 and $86,000.
Glassnode said long-term holder selling into that area had slowed. Selling pressure ran below half of August’s pace, the firm added.
The move pushed Bitcoin through an area where several investor groups previously approached break-even. Holding above that band keeps recent ETF buyers profitable.
BTC Price Faces Higher Derivatives Exposure
Derivatives activity rose alongside the spot-market recovery. CoinGlass showed Bitcoin futures open interest near $61.31 billion on Wednesday.
The same dataset showed about $72.27 billion in 24-hour futures volume. Spot volume on tracked exchanges stood near $5.68 billion.
Higher open interest can amplify price swings when leveraged positions build quickly. It does not indicate direction by itself.
The futures data also showed Bitcoin trading around $86,420 during the session. That kept BTC price above most of Glassnode’s earlier resistance band.
ETF demand provided a separate spot-market signal. Four consecutive positive sessions followed the Sept. 15 and Sept. 16 redemptions.
Across Sept. 17, Sept. 18, Sept. 21 and Sept. 22, Farside’s published totals exceeded $1.95 billion. Tuesday’s figure excluded BlackRock’s blank entry.
Bitcoin ETF Flows Put $87,000 Back in Focus
The next market test sits near Wednesday’s intraday move above $87,000. A sustained break would keep BTC price above Glassnode’s institutional break-even zone.
Investors will also watch the next U.S. Bitcoin ETF flow update. Another positive session would extend the current inflow streak.
Farside updates fund-level flows after issuers report daily activity. SoSoValue also tracks aggregate net flows across U.S. spot products.
For BTC price, the $83,000 to $86,000 area remains the nearest verified institutional cost-basis zone. Wednesday’s session kept Bitcoin above most of that range.
