U.S. spot Bitcoin exchange-traded funds recorded $137.6 million in net inflows on August 6, extending a positive streak to four consecutive trading sessions, with BlackRock's iShares Bitcoin Trust (IBIT) accounting for the lion's share of fresh demand. The funds, approved by the SEC in January 2024 after a decade of regulatory rejections, have become one of the most successful ETF launches in history, giving institutional and retail investors direct Bitcoin exposure through traditional brokerage accounts.

IBIT attracted $128.3 million during the session, representing the bulk of industry-wide net inflows. BlackRock, the world's largest asset manager with over $10 trillion in assets under management, has leveraged its distribution network to make IBIT the dominant vehicle in the spot Bitcoin ETF market. Other funds also saw additions: Fidelity's FBTC brought in $11.2 million, Bitwise's BITB gained $1.7 million, and Morgan Stanley's MSBT contributed $14.9 million. Morgan Stanley's participation is notable as one of the first major U.S. banks to offer spot Bitcoin ETF access to its brokerage clients. On the outflow side, VanEck's HODL recorded $32.8 million in net redemptions, partially offsetting the day's gains. Grayscale's GBTC and Bitcoin Mini Trust posted inflows of $7.5 million and $6.8 million, respectively.

Bitcoin ETFs Accumulate $763.6 Million Over Four Sessions

The August 6 result pushed cumulative net inflows since August 3 to $763.6 million, according to Farside Investors' daily fund data. The four-day breakdown shows $170.1 million on August 3, $211.5 million on August 4, $244.4 million on August 5, and $137.6 million on August 6.

IBIT alone supplied $606.8 million across those four sessions, accounting for nearly 80% of combined net inflows. BlackRock's fund has posted positive flows every single day during the current run.

This streak follows a seven-session inflow period between July 14 and July 22, during which regulated Bitcoin products absorbed approximately $981 million as Bitcoin recovered toward the mid-$60,000 range.

Bitcoin traded around $64,500 on August 6, with ETF demand remaining positive despite ongoing price volatility rather than a sustained upward breakout.

Ethereum ETFs Draw $92.1 Million

U.S. spot Ether ETFs concurrently attracted $92.1 million on August 6. The products began trading on July 23, 2024, making them newer entrants than their Bitcoin counterparts. BlackRock's ETHA led with $81.1 million in inflows. Fidelity's FETH added $2 million, Bitwise's ETHW gained $1.4 million, and Grayscale's Mini Ethereum Trust and ETHE brought in $4.5 million and $3.1 million, respectively.

The positive session built on $53.1 million in Ether ETF inflows on August 4 and $60.8 million on August 5. The products had started the week with an $11.9 million net outflow on August 3.

Bitcoin and Ether funds previously returned to simultaneous inflows on July 14, recording a combined $239.4 million and marking the start of another period of stronger regulated crypto demand.

IBIT Continues to Dominate Bitcoin Fund Flows

IBIT's $128.3 million addition on August 6 stands out within a broader period during which BlackRock's fund has repeatedly driven Bitcoin ETF flows on both the creation and redemption sides. In June, the fund added $66.4 million even as the wider ETF market recorded net redemptions.

The latest inflow represents net creations into IBIT rather than a discretionary Bitcoin purchase by BlackRock itself. ETF creations, redemptions, and custody settlement determine changes in the trust's Bitcoin exposure, while BlackRock operates the product on behalf of shareholders.

According to Farside's data, the August 6 table closed with $137.6 million in total Bitcoin ETF inflows and $92.1 million across the U.S. spot Ether ETF group.
