Bitcoin ETF Holders Become Profitable, Trading Volumes Surge to $4.5 Billion
Bloomberg ETF strategist James Seyffart said the average U.S. spot Bitcoin ETF holder has returned to profit for the first time since January. This comes amid the strong BTC price rally to $87,000, moving past the estimated ETF cost basis of $81,722 per coin.
According to data from Farisde Investors, inflows into spot Bitcoin ETFs exceeded $999 million on Monday, September 21. This comes as BTC price broke past the $83,000 resistance for the first time since January 2026.
The data shows that BlackRock’s iShares Bitcoin Trust (IBIT) led the inflows at $381.4 million. This was followed by Ark Invest’s ARKB, which saw inflows of $289 million, followed by Fidelity’s FBTC at $238 million in inflows.
Seyffart reported that U.S. spot Bitcoin ETFs recorded around $4.5 billion in trading volume during the session. He also noted that the figure was only slightly below the $4.6 billion recorded last Friday, despite the latest BTC price rally.
Bitcoin ETF Demand Remains Robust Despite All Odds
Last week, the net inflows into spot Bitcoin ETFs stood at just $42.6 million. This was due to uncertainty and negative sentiment stemming from the CLARITY Act’s failure and US CPI data hinting at sticky inflation.
However, Bitcoin price looked past all odds, surging to $85,000 on Sept. 21. At the same time, the Bitcoin ETFs also kicked off the week on a strong note with nearly $1 billion in inflows, showing strong institutional demand.
The latest Federal Reserve rate increase failed to trigger a major negative reaction. The failure of the CLARITY Act to advance in the Senate seems to have had a limited impact in the crypto market.
At the same time, global debt and inflation concerns are supporting demand for Bitcoin as a potential fiat hedge. The earlier 50% market crash also cleared out speculative participants, while renewed buying through ETFs is adding further demand.
BTC Price Gears Up for Uptober Rally
Historically, October has been one of the strongest months for Bitcoin. Analysts are now seeing the famous Uptober rally for BTC price as we enter Q4.
Blockchain analytics firm Glassnode reported that Bitcoin remains in a bullish regime across various cost-basis models and time frames. It noted that BTC is trading above both the True Market Mean and the short-term holder cost basis. Historically, holding above these levels has been associated with sustained uptrends.
If all the on-chain factors support, analysts are now hopeful that BTC price could surge past $100K by the end of 2026. All eyes are now on how long it will take Bitcoin to make fresh all-time highs.
