U.S. spot Bitcoin exchange-traded funds (ETFs) recorded $999 million in net inflows on Monday, September 21, as Bitcoin's price extended its recovery toward $87,000, according to data from Farisde Investors. The strong single-day total underscored renewed institutional appetite for the asset after a quiet prior week.

BlackRock's iShares Bitcoin Trust (IBIT) led the session with $381.4 million in net inflows. ARK 21Shares' ARKB followed with $289.1 million, while Fidelity's FBTC attracted $238.8 million, making them the top three destinations for the day's flows.

The inflows arrived as Bitcoin climbed above the $83,000 resistance level for the first time since January 2026, a move that also pushed the asset past the estimated average acquisition cost for U.S. spot ETF investors.

Average ETF Holder Back in Profit

James Seyffart, ETF analyst at Bloomberg Intelligence, said the average U.S. spot Bitcoin ETF holder has returned to profit for the first time since January. With Bitcoin rallying to $87,000, the asset has moved past the estimated ETF cost basis of $81,722 per coin, meaning investors at the average cost basis are once again sitting on unrealized gains (X post).

Seyffart also reported that U.S. spot Bitcoin ETFs recorded roughly $4.5 billion in trading volume during the session. He noted that the figure came in only slightly below the $4.6 billion logged the previous Friday, despite the latest leg of Bitcoin's rally (X post).

Demand Holds Up After a Weak Week

Last week, net inflows into spot Bitcoin ETFs stood at just $42.6 million, weighed down by uncertainty and negative sentiment stemming from the CLARITY Act's failure and U.S. CPI data hinting at sticky inflation.

Bitcoin, however, looked past those headwinds and surged to $85,000 on September 21. The ETF complex likewise kicked off the new week on a strong note, taking in nearly $1 billion in inflows and signaling robust institutional demand.

The latest Federal Reserve rate increase failed to trigger a major negative reaction, and the CLARITY Act's failure to advance in the Senate appears to have had only a limited impact on the crypto market. Meanwhile, global debt and inflation concerns continue to support demand for Bitcoin as a potential hedge against fiat currencies. The earlier 50% market crash also cleared out speculative participants, while renewed buying through ETFs is adding further demand.

Bitcoin Sets Sights on 'Uptober'

October has historically been one of the strongest months for Bitcoin, and analysts are now watching for the seasonal "Uptober" rally as the market enters the fourth quarter.

Blockchain analytics firm Glassnode reported that Bitcoin remains in a bullish regime across various cost-basis models and time frames. The firm noted that BTC is trading above both the True Market Mean and the short-term holder cost basis, levels that have historically been associated with sustained uptrends.

If on-chain factors remain supportive, analysts are hopeful that Bitcoin's price could surge past $100,000 by the end of 2026. All eyes are now on how long it will take Bitcoin to reach fresh all-time highs.
