US spot Bitcoin exchange-traded funds recorded $526.7 million in net inflows on Monday, marking their largest daily intake since September 22. This surge reversed the previous day's $82.4 million in net outflows and ended a two-week streak of weekly withdrawals for the asset class. BlackRock’s iShares Bitcoin Trust (IBIT) drove the majority of this activity with $665.2 million in inflows, a figure that exceeded the net total across all US spot Bitcoin ETFs combined. These gains were partially offset by significant withdrawals from other major funds, including $83.6 million from Fidelity’s Wise Origin Bitcoin Fund (FBTC) and $54.9 million from Grayscale Bitcoin Trust (GBTC). According to data from Farside Investors, other funds experienced no net flows during the session.
The strong performance on Monday contrasts with recent volatility, as the funds had shed approximately $229 million last week following a loss of $681 million the week prior. Additionally, October 7 saw $483.9 million in outflows, which was the largest daily withdrawal since June. Despite Monday’s substantial inflow, US spot Bitcoin ETFs remain in negative territory for the month of October by about $88 million. In parallel, US spot Ether ETFs faced continued pressure, recording $103.3 million in net outflows on Monday. BlackRock’s iShares Ethereum Trust (ETHA) led these losses with $95.4 million in withdrawals. Ether funds have now posted three consecutive weeks of net withdrawals, losing about $320 million last week.
The concentration of inflows within BlackRock’s IBIT highlights a diverging landscape among institutional crypto products, where market leadership is increasingly defined by specific fund performance rather than broad sector sentiment. While the aggregate $526.7 million inflow signals renewed investor appetite for Bitcoin exposure, the fact that IBIT alone accounted for more than the net total underscores significant capital rotation away from competitors like Fidelity and Grayscale. This dynamic suggests that investors are prioritizing liquidity and scale when entering the spot ETF market, potentially accelerating consolidation among issuers who cannot match BlackRock’s trading volume or fee structures.
From a Market Structure perspective, the simultaneous strength in Bitcoin ETFs and weakness in Ether ETFs indicates a bifurcation in digital asset investment strategies. The persistent outflows from Ether funds, particularly ETHA, contrast sharply with the rebound in Bitcoin products, suggesting that macroeconomic factors or regulatory uncertainties may be disproportionately affecting Ethereum-based instruments. For institutional allocators, this divergence serves as a critical signal to reassess risk exposure between the two leading cryptocurrencies, as the current flow patterns imply that Bitcoin retains its status as the primary hedge against traditional financial instability, while Ether faces headwinds related to staking mechanics or broader network concerns.
