U.S. spot Bitcoin (BTC) funds drew $999 million on Monday, their largest daily inflow in 11 months, as the coin briefly cleared $87,000.
Key Points:
- Spot Bitcoin ETFs took in nearly $1 billion on Sept. 21, the most since Oct. 6, 2025.
- Bitcoin touched about $87,300 before easing back toward $85,400 on Tuesday.
- Analysts credit institutional buying and short covering, while sentiment gauges flash caution.
Bitcoin ETF Inflows
Net inflows reached $998.95 million on Sept. 21, according to SoSoValue data. BlackRock's IBIT led with $381.4 million, followed by ARKB from Ark Invest and 21Shares at $289.1 million and Fidelity's FBTC at $238.8 million.
The last time the funds pulled in more was Oct. 6, 2025, when they absorbed $1.2 billion in one session.
Spot Ether (ETH) funds added $269.98 million, their best day since Oct. 7, 2025.
The Bitcoin buying followed heavy withdrawals earlier in the month, including $450.4 million on Sept. 15 and $295.9 million on Sept. 16, and every fund reporting a non-zero flow finished positive. Morgan Stanley's MSBT took in a record $61.7 million. Monday lifted cumulative inflows into the category to roughly $56.23 billion, with total fund assets near $110.1 billion.

Rally Drivers
Bitcoin rose as high as about $87,300 on Monday, its highest level since January 2026, and traded near $85,400 early Tuesday. Min Jung, a research associate at Presto Research, said no single catalyst explained the move, pointing instead to risk appetite, ETF demand and short covering.
Short sellers took the heaviest damage.
Crypto liquidations totaled $1.06 billion over 24 hours, including $844 million in short positions, CoinGlass data showed. Jeff Ko, chief analyst at ViaBTC, said clearing the $82,000 level that had capped prices likely pulled systematic strategies back in.
Jeff Mei, chief operating officer at BTSE, said institutional investors are flocking back to Bitcoin because of favorable macro factors. He cited falling oil prices, easing Treasury yields and this week's meeting between the U.S. and Chinese presidents. Dominick John of Zeus Research said traders are now watching whether Bitcoin holds above $85,000 and Ether above $2,700.
Bitcoin Sentiment Swing
The Crypto Fear and Greed Index jumped to 78 on Sept. 21 from 51 a week earlier, while Santiment tracked the most bullish social commentary since December 2024. Open interest climbed 7.6% to about $156 billion, a sign traders added leverage rather than trimmed it.
Crowded positioning of that kind has often preceded pauses rather than fresh highs.
The mood has turned quickly. Bitcoin slipped below $60,000 in late June, and the gauge read 25 on Aug. 6 before the coin climbed from under $68,000 toward $80,000 later that month. Even after this week's run, it trades well below its October 2025 record of $126,198.
