How the Data Is Measured
Figures from SoSoValue, which compiles daily creations and redemptions directly from issuer disclosures filed to U.S. exchanges such as Cboe, Nasdaq and NYSE, show that spot Bitcoin ETFs have seen five consecutive days of net inflows. This brought in an estimated 2.3 to 2.4 billion dollars, pushing cumulative net inflows above 56.8 billion and total assets under management to roughly 153 billion dollars. SoSoValue includes only confirmed issuer filings, meaning the data reflects actual settled creations rather than estimates or indicative flows.
The platform’s U.S. Bitcoin dashboard tracks ten major products, including the iShares Bitcoin Trust (IBIT) from BlackRock, the Fidelity Wise Origin Bitcoin Fund (FBTC) from Fidelity Investments, the ARK 21Shares Bitcoin ETF (ARKB), the Bitwise Bitcoin ETF (BITB), the VanEck Bitcoin Trust (HODL), the Valkyrie Bitcoin Fund (BRRR), the Invesco Galaxy Bitcoin ETF (BTCO), the Franklin Templeton Bitcoin ETF (EZBC), the WisdomTree Bitcoin Fund (BTCW) and the converted Grayscale Bitcoin Trust (GBTC). These ten vehicles account for virtually all spot Bitcoin ETF activity in the U.S. market and are the benchmark for gauging institutional flows.
Ethereum ETFs Gaining Ground
Ethereum’s spot ETFs, which launched in July 2024 after approval by the U.S. Securities and Exchange Commission, are also attracting growing institutional allocations. The iShares Ethereum Trust (ETHA) from BlackRock and the Fidelity Ethereum Fund (FETH) from Fidelity Investments have led the latest inflow wave, each reportedly taking in over 160 million dollars in a single session. Other issuers such as VanEck (ETHV), Bitwise (ETHW), Invesco Galaxy (QETH) and Franklin Templeton (EZET) have also recorded steady inflows.
SoSoValue data shows cumulative net inflows into Ethereum ETFs now exceeding 13 billion dollars, with total net assets nearing 30 billion. This is a sharp reversal from August, when Ethereum ETFs saw about 3.9 billion dollars in net inflows while Bitcoin ETFs recorded net outflows of around 750 million over the same period.
Market and Macro Drivers
Analysts say the shift is being driven by two converging forces: regulatory clarity and macroeconomic relief. The SEC’s approval of multiple Ether ETFs created a unified compliance framework that major asset managers can apply to both Bitcoin and Ethereum, lowering operational friction. Simultaneously, cooling U.S. inflation and widespread expectations that the Federal Reserve will cut interest rates at its September meeting have revived risk appetite among multi-asset institutional portfolios.
A chief investment officer at a major crypto trading firm said that the declining opportunity cost of holding non-yielding assets is prompting allocators to reweight toward alternative stores of value. According to the executive, this makes Bitcoin and Ethereum “look more like strategic positions than speculative trades” for the first time in months.
Why This Streak Stands Out
This latest Bitcoin inflow streak is notable not just for its size but for its breadth. Previous surges were often concentrated in one or two funds, such as IBIT or FBTC, while the current wave has included simultaneous creations across nearly every major issuer. The resulting inflows have been measured in the hundreds of millions of dollars per day, with several days surpassing 600 million.
By contrast, late August saw daily Bitcoin ETF flows fluctuate between minor inflows and outflows while Ethereum dominated new allocations. The sharp rotation back to Bitcoin, coupled with steady Ethereum demand, signals that institutional portfolios are now treating both assets as core holdings rather than opportunistic plays.
A Shift Toward Maturity
If the momentum continues, the spot ETF complex could mark a new phase in digital asset markets—one where institutional allocations to Bitcoin and Ethereum become a baseline expectation rather than an experimental trade. The combination of lower rates, regulatory clarity, and broad-based fund participation is helping to reshape the profile of crypto within traditional finance.
For now, analysts say, the message is clear: regulated crypto exposure is no longer a side bet. It is becoming infrastructure.
