The U.S. spot bitcoin ETF hit its largest single-day net inflow in nearly eight months, and the return of institutional demand boosted the currency price to rebound.
On Thursday, driven by improved macroeconomic expectations, bitcoin prices regained their footing. The US$80,000 mark drove the U.S. spot bitcoin exchange-traded fund (ETF) to record its largest single-day inflow in nearly eight months. Data showed that the funds attracted net inflows of approximately $730.9 million on September 3, the strongest day since January 14.
Overview of capital flows to major ETFs
BlackRock's iShares Bitcoin Trust (IBIT) dominates with a net inflow of approximately US$454 million. ARK 21Shares 'ARKB followed closely, with a net inflow of $137.8 million; Fidelity's FBTC increased by $74.4 million. The grayscale Bitcoin mini trust recorded an inflow of US$48.8 million, and GBTC increased by US$8.2 million. Other small funds also recorded small inflows.
The strong buying was partially offset by a net outflow of $19.6 million from VanEck's HODL fund and a net outflow of $5.2 million from WisdomTree's BTCW fund.
Return of institutional demand helps Bitcoin climb
New ETF demand coincides with the sharp rebound in Bitcoin prices. As of press time, Bitcoin was trading at approximately US$80,991, up 4.45% in the past 24 hours. After rallying from below $78,000 earlier in the trading day, cryptocurrency prices briefly exceeded the $81,000 mark.
Currently, Bitcoin's market capitalization rate is approximately US$1.63 trillion, and its 24-hour transaction volume reaches US$68.61 billion.
The latest inflows continue the recent strong momentum of the U.S. spot Bitcoin ETF. Throughout August, the funds attracted approximately $3.5 billion in funding, their best monthly performance since September 2025.
Improved macroeconomic environment boosts market sentiment
Expected improvements in the U.S. macroeconomic environment will help boost confidence in risky assets. Analysts pointed to recent comments by Federal Reserve Governor Christopher Waller as one of the main catalysts, and the U.S. Treasury's move to expand its repurchase program also helped boost the crypto market rebound in August.
Thursday's US$731 million inflow of ETF funds may send another important signal that institutional demand for bitcoin is recovering. The key question is whether these inflows can last long enough to help Bitcoin establish a more solid foundation above $81,000.
