BlackRock’s Spot Bitcoin ETF IBIT Jumps Nearly 6% as Daily Inflows Hit $300M

BlackRock’s spot Bitcoin ETF IBIT is back in focus after reports tied a nearly 6% move to roughly $300 million in daily inflows, landing as Bitcoin trades near $81,443 on Sept. 4, 2026. The readable flow data complicates the framing: the $300 million figure lines up with the entire U.S. spot Bitcoin ETF complex on its strongest recent sessions, not IBIT alone.

IBIT Climbs as Bitcoin ETF Demand Strengthens

Bitcoin was changing hands at $81,443 at press time, up about 5.6% over 24 hours, with a market cap near $1.64 trillion and 24-hour volume around $38.5 billion. That spot strength is the backdrop for the renewed attention on IBIT and its inflow trajectory. For related coverage, see US Spot Bitcoin ETFs Lose $332M in 4 Sessions as BTC Falls.

The claim that IBIT itself rose nearly 6% on the same session as a $300 million inflow print remains unconfirmed; no readable authoritative page reviewed here ties that exact price move to a matching single-day IBIT flow.

What the date-stamped flow table does show is more modest at the fund level. Farside recorded IBIT at $115.4 million of net inflows on Sept. 2, 2026, while the entire U.S. spot Bitcoin ETF category took in $101.1 million that day, per Farside’s flow data.

What the $300M Inflow Figure Actually Signals

The roughly $300 million number does appear in recent sessions, but as a category total: Aug. 21 saw $307.5 million and Aug. 25 saw $314.3 million across all U.S. spot Bitcoin ETFs, with IBIT itself contributing $239.3 million and $284.4 million on those dates. The distinction matters for anyone reading the flows as a pure IBIT demand signal. For related coverage, see XRP ETF Inflows Put Ripple Ahead in September.

There is precedent for the mix-up. When U.S. spot Bitcoin ETFs pulled in $301 million in a single day in July 2024, IBIT led with $117.25 million, The Block reported, not the full $300 million. Bitcoin traded around $64,770 at that publication, showing how flow headlines track price reaction.

Even so, IBIT’s scale is not in question. Cumulative net inflows into the fund stood at $63,485 million as of Sept. 3, 2026, against $54,781 million for the entire U.S. spot Bitcoin ETF category, meaning IBIT alone has absorbed more than the complex’s net total.

That leadership is consistent with earlier institutional footprints, including UAE sovereign funds holding $764 million in the fund and Brevan Howard retaining $255 million in IBIT after trimming exposure. IBIT remains the default institutional access point even as individual allocators rotate.

Why the Price Gain and Inflows Matter for Market Watchers

BlackRock’s issuer page lists IBIT net assets at $60,018,939,295, a $43.79 closing price, and daily volume of 30,549,677 shares as of Sep. 2, 2026, according to iShares. The trust, launched Jan. 5, 2024, is built to reflect the price of bitcoin rather than offer direct custody.

Sentiment is leaning bullish alongside the flows. The Fear & Greed Index reads 65, in Greed territory, a backdrop that often amplifies interest in ETF exposure. BlackRock has also moved to widen access, recently cutting IBIT’s self-custody transfer minimum to $1 million.

What to watch next: whether IBIT’s own daily prints climb toward the $300 million mark seen only at the category level, and how flows hold if Bitcoin sustains above $80,000. The gap between recent U.S. ETF outflows, when the complex shed $332 million across four sessions, and current inflows will define near-term conviction.
