U.S. spot Bitcoin ETFs have recorded $730.9 million in net inflows in their strongest single trading session since mid-January, led by more than $450 million entering BlackRock\u2019s iShares Bitcoin Trust.<\/p>\n
\n Summary<\/span>\n <\/p>\n <\/p>\n According to SoSoValue data<\/a> for Sept. 3, the group posted its largest daily inflow since Jan. 14, when the funds attracted $843.6 million, pushing cumulative net inflows since their January 2024 launch to $55.44 billion.<\/p>\n BlackRock\u2019s IBIT accounted for $454 million of Thursday\u2019s inflows, representing more than 60% of the total. The latest allocation brought the fund\u2019s cumulative net inflows to $63.94 billion.<\/p>\n ARK Invest and 21Shares\u2019 ARKB ranked second with $138 million, while Fidelity\u2019s FBTC received roughly $74 million. Grayscale\u2019s two Bitcoin products drew a combined $57 million during the session.<\/p>\n VanEck\u2019s HODL and WisdomTree\u2019s BTCW were the only products to record withdrawals. HODL lost close to $20 million, while approximately $5 million left BTCW.<\/p>\n The inflows arrived as Bitcoin rebounded sharply, with the U.S.-listed funds gaining between 5.7% and 5.9% during Thursday\u2019s trading session. Their combined net assets climbed to $103.34 billion, equivalent to 6.32% of Bitcoin\u2019s market capitalization.<\/p>\n Thursday\u2019s result was more than three times the size of any single daily inflow recorded during an 11-session run of positive flows in late August.<\/p>\n The latest buying followed an active August for the products. U.S. Bitcoin ETFs collected $1.92 billion during the five trading sessions ending Aug. 21, when Bitcoin and Ether ETFs<\/a> together attracted $2.61 billion in their strongest combined week since October 2025.<\/p>\n Bitcoin funds accounted for roughly 73% of those flows, while spot Ether ETFs received $697.47 million during the same five-day period.<\/p>\n IBIT has repeatedly accounted for a large share of the money entering U.S. spot Bitcoin ETFs during recent periods of buying.<\/p>\n Crypto.news previously reported that the funds attracted $853.5 million over five days<\/a> from Aug. 3 through Aug. 7. BlackRock\u2019s fund brought in an estimated $693 million during the run, equivalent to roughly 81% of the group\u2019s total inflows.<\/p>\n The pattern continued later in August. QCP Capital said Bitcoin\u2019s advance from approximately $63,500 to above $80,000 was supported by spot buying while futures positioning declined. During part of the rally, spot Bitcoin ETFs drew $2.8 billion<\/a> across eight consecutive sessions.<\/p>\n Futures open interest fell from 646,000 BTC to 588,000 BTC as Bitcoin advanced, according to QCP, separating the price move from rallies driven primarily by an increase in leveraged positions.<\/p>\n <\/p>\n IBIT has remained the largest U.S. spot Bitcoin ETF by assets through the changes in daily flows. BlackRock had reported $60.52 billion in net assets for the fund as of Aug. 26, before Bitcoin\u2019s latest advance and Thursday\u2019s increase in ETF asset values.<\/p>\n Institutional filings have shown large positions in the fund as well. Jane Street reported more than $1 billion in U.S. spot Bitcoin ETF shares as of June 30, including approximately $828 million in IBIT<\/a>. The quarterly filing represented positions at the end of June and did not disclose the trading firm\u2019s current exposure.<\/p>\n Large inflows have not produced a continuous run of buying across every trading day.<\/p>\n The U.S. products recorded $201.9 million in net outflows on Aug. 28, ending nine consecutive sessions of inflows. ARK 21Shares\u2019 ARKB led the withdrawals with $114.9 million, while IBIT lost $33.4 million.<\/p>\n Despite the final negative session, the funds still attracted a combined $924.5 million during the Aug. 24 to Aug. 28 trading week.<\/p>\n Flows reversed again as September began. Investors withdrew $236 million from the funds on Sept. 1, with IBIT accounting for roughly $201 million of the redemptions.<\/p>\n SoSoValue data showed the group returned to net buying the following session, taking in approximately $101 million on Sept. 2. IBIT received roughly $115 million, offsetting withdrawals elsewhere in the group before Thursday\u2019s much larger allocation.<\/p>\n The $454 million that entered IBIT on Sept. 3 therefore came two sessions after the fund recorded a $201 million withdrawal, putting BlackRock\u2019s product on both sides of the largest daily moves during the opening days of September.<\/p>\n The recent swings follow a period when Bitcoin ETF demand had already recovered from sustained withdrawals earlier in the year. The products entered July after eight consecutive negative weeks, including $527 million in withdrawals<\/a> during the four trading days ending July 2.<\/p>\n A $221.7 million inflow on July 2 ended a 10-day daily withdrawal run, while BlackRock returned to larger allocations days later. IBIT received $209.4 million on July 7 as total daily inflows across the U.S. Bitcoin ETFs reached $265.7 million.<\/p>\n By July 30, another $233.1 million entered the products, with BlackRock taking $183.4 million. The fund accounted for 78.7% of that session\u2019s inflows.<\/p>\n Thursday\u2019s $730.9 million allocation has now exceeded each of those daily totals, while the combined net asset value of the U.S. spot Bitcoin ETF market has moved above $103 billion.<\/p>\n <\/p><\/div>\n\n\n
