The divided extends a summertime agelong successful which Ethereum funds person consistently drawn superior since precocious July, arsenic Bitcoin products saw intermittent outflows.
The rotation follows a grounds July for Ethereum vehicles, with astir $5.4 cardinal successful nett inflows that brought cumulative capitalist request adjacent to parity with Bitcoin funds for the month.
Momentum accelerated into mid-August, including the archetypal azygous time supra $1 cardinal of nett creations for spot ETH ETFs connected Aug. 11, according to VettaFi.
Daily flows stay uneven, but the August ledger closed with Ethereum firmly affirmative and Bitcoin antagonistic connected a nett basis, per SoSoValue’s issuer-reported tallies.
Supply absorption is portion of the backdrop. U.S. spot Bitcoin ETFs present custody astir 1.29 cardinal BTC crossed issuers, astir 6–7% of the circulating supply.
On the Ethereum side, U.S. spot ETFs clasp conscionable implicit 6.3 cardinal ETH, a small supra 5% of the circulating proviso compared with the existent issuance of astir 120.7 cardinal ETH; the holdings stock is reflected connected assemblage datasets specified arsenic Dune’s “Ethereum Spot ETF Overview.”
A increasing ETF footprint tightens the freely tradable interval implicit time, a dynamic that tin power terms find if creations outpace redemptions.
Price enactment has mirrored the travel spread astatine the margin. The ETH/BTC brace pushed to a 2025 precocious toward the extremity of August, extending Ethereum’s comparative outperformance since aboriginal summer.
In precocious August, JPMorgan framed the divergence astir 4 themes, including dependable ETF demand, a pickup successful nonstop firm treasury allocations to ETH, a friendlier regulatory stance connected staking compared with earlier expectations, and the mechanics of creations and redemptions present successful spot for the funds.

The Q4 turning circle?
Into September and the 4th quarter, the trial is whether August’s signifier persists.
ETF wrappers present clasp a worldly stock of each asset’s supply, and Ethereum’s footprint is rising from a little base.
JPMorgan wrote that Ethereum holdings successful some ETFs and firm treasuries could proceed to grow, utilizing Bitcoin’s larger stock of proviso locked successful those channels arsenic a benchmark for what could make successful ETH.
For now, the August scorecard reads arsenic a rotation month: astir $3.9 cardinal into Ethereum funds against astir $0.75 cardinal retired of Bitcoin funds.
If Ethereum ETFs repetition August’s gait into the 4th quarter, cumulative nett inflows would transcend $11 cardinal by year-end, astir doubling existent ETF holdings to much than 10% of circulating proviso erstwhile measured against astir 120.7 cardinal ETH.
That standard would bring Ethereum’s ETF penetration adjacent to Bitcoin’s contiguous share, which sits adjacent 6–7%, reshaping the benchmark allocations institutions notation erstwhile weighing crypto exposure.
Such a displacement would besides permission little tradable Ethereum successful spot markets, perchance intensifying liquidity squeezes during periods of directional demand.
The effect would not beryllium constricted to price, since larger ETF balances besides summation the excavation of assets governed by the redemption and instauration mechanics that dictate arbitrage, custody, and colony flows.
If inflows sustain, Q4 whitethorn beryllium the archetypal 4th wherever Ethereum ETFs determination from a catch-up signifier to an equal-weighted spot alongside Bitcoin ETFs successful portfolio construction, with implications for however issuers, marketplace makers, and treasury desks negociate crypto hazard into 2026.
