U.S. spot Bitcoin ETFs attracted $314.37 million on Tuesday, extending their inflow streak to a seventh consecutive session and pushing combined net assets to $99.05 billion — just short of the $100 billion mark. The funds, which began trading in the United States in January 2024, are tracked closely because their daily creations and redemptions offer a read on institutional and adviser demand for regulated Bitcoin exposure.

BlackRock’s iShares Bitcoin Trust (IBIT), the largest U.S. spot Bitcoin fund by assets, absorbed $284.42 million, or more than 90% of the day’s total. The remaining $29.95 million was split between the four other funds that drew money: Fidelity’s FBTC took in $15.45 million, Grayscale’s Bitcoin Mini Trust $6.98 million, Morgan Stanley’s MSBT $4.52 million, and Bitwise’s BITB $3 million. No spot Bitcoin fund recorded outflows on the day.

IBIT’s dominance is consistent with its longer-term standing in the market. In January, Cryptopolitan reported that the fund controlled almost 70% of spot bitcoin ETF trading volume and held more than $66 billion in assets under management.

Monthly and cumulative totals climb

Across the spot Bitcoin funds, total trading value reached $3.52 billion. The week’s seven sessions collected $2.57 billion, while August inflows now stand at $3.03 billion — $390 million short of the monthly total for October 2025, with four trading days still to go.

The recovery has cut this year’s net outflow deficit by more than half, to $2.26 billion, while cumulative net inflows since launch stand at $54.36 billion.

BlackRock leads Ether ETFs as well

Spot Ether ETFs, which launched in the U.S. in July 2024, brought in $179.80 million, extending their own seven-day streak as of Tuesday, August 25. BlackRock’s ETHA led with $146.44 million, followed by Fidelity’s FETH at $25.75 million and BlackRock’s ETHB at $7.61 million; the asset manager’s two funds together accounted for the bulk of the day’s ether flows. Together, the ether funds hold $14.88 billion in net assets.

Other crypto ETFs also drew fresh cash. Solana ETFs took in $32.25 million, four XRP funds $23.87 million, and HYPE ETFs $7.51 million. These altcoin products are newer additions to the U.S. crypto fund lineup, so their early flows are watched as a test of investor appetite beyond Bitcoin and Ether. Separately, Cryptopolitan reported that Grayscale converted its Zcash Trust into an ETF, ZCSH, which trades on NYSE Arca; as of August 24, the fund held about $314 million in assets and roughly 387,200 ZEC. The conversion follows the same trust-to-ETF playbook Grayscale used for its Bitcoin and Ether trusts in 2024.

Prices slip even as ETF demand builds

Bitcoin briefly crossed the $80,000 level before sliding back, trading at $78,447.81 on Wednesday, according to CoinGecko. Ethereum, according to CoinGecko, changed hands at $2,462.96, down 0.4%, at press time. Both assets remain sharply higher for the week, with Bitcoin up 14.6% and Ether up 17.9%.

The Crypto Fear & Greed Index, a sentiment gauge published by Alternative.me, cooled to 65 from 74, remaining in “Greed” territory but softening. Crypto ETF demand continued to build even as spot prices lost ground.
