BlackRock's spot Bitcoin ETF IBIT soared nearly 6%, with daily inflows reaching US$300 million

BlackRock's spot Bitcoin ETF IBIT has regained the focus of the market. It was previously reported that its single-day capital inflow was about US$300 million, driving price fluctuations by nearly 6%. As of September 4, 2026, the Bitcoin transaction price is approximately US$81,443. Clearly readable flow of funds data complicates this statement: the $300 million figure actually corresponds to the total inflow of the entire U.S. spot Bitcoin ETF sector during the strongest trading day in recent times, rather than just IBIT.

IBIT rose with stronger demand for Bitcoin ETF

As of press time, Bitcoin trading price was US$81,443, up about 5.6% in 24 hours, with a market value of nearly US$1.64 trillion, and a 24-hour trading volume of approximately US$38.5 billion. This strong performance in the spot market is the background for renewed attention to IBIT and its capital inflow trajectory. The claim that IBIT surged by nearly 6% in a single day while flowing in US$300 million has not been confirmed; no authoritative pages reviewed directly correspond this specific price change to IBIT's single-day capital flow data. Until issuer or exchange data is confirmed, the title pairing should be regarded as a single-source statement. The dated flow of funds statement shows that the fund-level data is more moderate. According to Farside's flow of funds data, on September 2, 2026, IBIT recorded a net inflow of US$115.4 million, while the total net inflow of the entire U.S. spot Bitcoin ETF sector on that day was US$101.1 million.

What does the US$300 million inflow data mean?

The figure of nearly $300 million did appear in recent trading days, but this is the sum of the entire sector: on August 21, the total inflow of all U.S. spot Bitcoin ETFs was $307.5 million; on August 25, it was $314.3 million, of which IBIT contributed $239.3 million and $284.4 million respectively. This distinction is crucial for those who interpret capital flows as purely IBIT demand signals. Such confusion is not unprecedented. In July 2024, the net inflow of U.S. spot Bitcoin ETF in a single day was US$301 million. According to The Block, IBIT led the way with US$117.25 million, rather than the full amount of US$300 million. Bitcoin was trading at approximately $64,770 at the time, showing a correlation between capital flow headlines and price reactions. Even so, there is no doubt about the scale of IBIT. As of September 3, 2026, IBIT's cumulative net inflow was US$63.485 billion, while the cumulative net inflow of the entire U.S. spot Bitcoin ETF sector was US$54.781 billion, which means that IBIT alone absorbed more funds than the entire sector's net total.

Cumulative net inflow to IBIT

US$63.485 billion

Farside's Bitcoin ETF flow table shows that as of September 3, 2026, the cumulative net inflow of BlackRock's IBIT was US$63.485 billion. This lead is consistent with earlier institutional layouts, including the US$764 million held by the United Arab Emirates sovereign fund and the US$255 million IBIT retained by Brevan Howard after cutting exposure. Even if individual fund allocators rotate, IBIT is still the default entry channel for institutions.

The significance of price increases and capital inflows for market observers

According to iShares data, BlackRock's issuer page shows that as of September 2, 2026, IBIT's net assets were US$60.018 billion, the closing price was US$43.79, and the daily trading volume was 30,549,677. The trust fund was established on January 5, 2024 and is designed to reflect the price of Bitcoin rather than provide direct custody services.

IBIT net assets

US$60.018 billion

BlackRock iShares page shows that as of September 2, 2026, IBIT net assets were US$60.018 billion. With the inflow of funds, there is more market sentiment. The Fear and Greed Index reads 65, in the greedy range, a background that often amplifies market interest in ETF exposure. BlackRock has also taken measures to expand access, recently reducing the minimum amount of IBIT's self-custodial transfers to US$1 million.

The next thing worth noting is: whether IBIT's own single-day capital inflows will climb to the level of US$300 million that occurs only at the sector level; and whether the capital flow can remain stable if Bitcoin continues to stand firm at the US$80,000 mark. The gap between the recent outflow of funds from U.S. ETFs (the sector has a cumulative outflow of US$332 million in four trading days) and the current inflow of funds will determine short-term market confidence.
