Bitcoin ETFs Pull In $731M, Mark Biggest Daily Inflow Since January

US Bitcoin ETFs are once again witnessing positive sentiment, with the funds hitting a remarkable $730.9 million in net inflows on September 3, 2026. What is more noteworthy is that the figure marks the largest single-day net inflows since January. 

Bitcoin ETFs see biggest inflows since January

Institutional investors are showing increasing interest in Bitcoin-based exchange-traded funds. This is reflected in the latest daily inflows of Bitcoin ETFs, with the inflows surging past $730 million. While this marked the biggest inflows in eight months, the BTC price has also reflected this positive sentiment.

According to SoSoValue data, the ETFs attracted $730.9 million in net inflows on Thursday. This marks a significant rise from the $101.2 million inflows reported on Wednesday. However, the figure still fell short of the $843.6 million recorded on January 14, 2026. This $843.6 million remains the largest daily Bitcoin ETF inflow this year.

BlackRock’s IBIT takes the lead

Interestingly, BlackRock’s iShares Bitcoin Trust (IBIT) emerged as the biggest contributor to Thursday’s inflows. The fund attracted $454 million in inflows, representing 62% of the total flows. On August 20, BlackRock reported a more notable inflow of $503 million.

At the same time, other Bitcoin products have also added to the flows. ARK Invest and 21Shares’ ARKB ranked second in the trend, reporting $137.7 million in net inflows. Following was Fidelity’s Wise Origin Bitcoin Fund (FBTC), which saw $74.4 million in flows. Also, Morgan Stanley’s MSBT had $7.3 million in positive flows, while Bitwise’s BITB brought $4.19 million into the market.

However, some funds experienced negative flows. For example, VanEck’s Bitcoin ETF (HODL) saw $19.6 million in outflows. WisdomTree’s Bitcoin Fund (BTCW) also reported negative sentiment with $5.2 million in outflows. Grayscale’s GBTC lost about $56.2 million.

Bitcoin whales show little signs of selling

In addition to increasing institutional interest, large Bitcoin whales are also showing positive sentiment. According to CryptoQuant, the whales are not rushing to take profits, even though the BTC price has surged past $80K. The Exchange Whale Ratio has dropped to 0.39. This means that investors are putting small shares of BTC into exchanges, indicating reduced selling pressure.

As of press time, BTC is trading at $81,094, marking a notable surge of nearly 5% in a day. With a 2.5% weekly surge, the crypto has a monthly rise of more than 26%. The 24-hour trading volume has also hit a high of $43.5 billion, increasing by about 70%.

Thus, the current situation looks overall positive for Bitcoin’s future performance. If the Whale Ratio keeps falling and Bitcoin ETF inflows continue to rise, it could build a significant positive background for the BTC price.
