Bitcoin Spot ETFs Record $876M Inflow as BlackRock’s IBIT Leads with $899M

The iShares Bitcoin Trust (IBIT) by BlackRock recorded the highest one-day inflow. The Wu Blockchain and SoSoValue report that IBIT posted net inflow of $899 million on Oct. 7. The daily intake of IBIT was higher than the flows of competing products. IBIT is currently at an approximate of a 97billion AUM. IBIT still has the major institutional demand.

吴说获悉，根据 SoSoValue 数据，昨日（美东时间 10 月 7 日）比特币现货 ETF 总净流入 8.76 亿美元，持续 7 日净流入。昨日单日净流入最多的比特币现货 ETF 为贝莱德 (Blackrock） ETF IBIT，单日净流入为 8.99 亿美元，目前 IBIT 历史总净流入达 645.04 亿美元。https://t.co/i9naTwKTI6

Data deviation and elucidation

The figure of IBIT of $899M is higher compared to the total number of ETF inflows of 876M. That is possible because vendors reported on varying reporting windows or other ETFs might report net outflows in the same 24-hour time. Another probable typo in the Wu posting is the inflows of the history of IBIT (645.04 billion). An amended and reasonable estimate is of an accumulated net inflows of about 64.504 billion in cumulative net inflows to IBIT since inception. I mark that as one of the formatting or reporting mistakes in the original post.

Scale and Historical Context

In January 2024, the U.S. spot Bitcoin ETFs were launched. Cumulative ETF AUM is close to being at $170B as of Oct. 7. Since inception, the ETFs recorded nearly 61.5B net inflows (industry totals). The $876M influx is the largest inflow day since the beginning of the cycle, but it is outpaced by the single-day peaks of up to 1.2 to 1.4B earlier in the cycle.

Price and Market Impact

ETF inflows provided apparent assistance to spot demand. Bitcoin was reported to be in the range of $118k -125k during the highlights of the period between 6-7 October. The $876M single day infusion is only a tiny fraction of the Bitcoin market cap at approximately $2.3T, but it generates price through focal purchasing and less liquidity on the available spot markets.

The existing trend is the most advantageous to BlackRock. Big ETFs like IBIT drag in headline flows and liquidity. Smaller ETFs attract much less volume every day. Traders monitor flow of ETFs as near-term momentum. Cumulative AUM is an indicator monitored by asset allocators, as a measure of institutional adoption.

Flows can reverse quickly. One mega outflow or an alteration in SEC/regulatory position can result in the reversal of the sign.
