Ethereum ETFs Surge With $216M Inflows as Bitcoin Funds Face Fourth Day of Outflows

US-based spot Ethereum exchange-traded funds recorded a dramatic surge in capital on Sept. 11, 2026, pulling in $216 million in net inflows. The sharp uptick contrasted with spot Bitcoin ETFs, which experienced a fourth consecutive session of capital withdrawals totaling $13.29 million, according to financial market data first reported by Yahoo Finance using tracking metrics from SoSoValue.

The single-day movement for Ethereum funds represents a sudden shift in investor sentiment within the cryptocurrency ETF landscape. Just two days prior, on Sept. 9, Ethereum funds registered $24 million in net outflows. The fresh cash injection coincided with a 3% gain in the spot price of Ether heading into the weekend, though the underlying token remains down 46.67% over the previous 12 months.

Meanwhile, Bitcoin funds continued a swift reversal from their performance earlier in the month. During the week ending Sept. 4, spot Bitcoin ETFs registered massive net inflows totaling $986.9 million. However, institutional authorized participants turned into net sellers over the subsequent four sessions, culminating in Friday’s $13.29 million redemption figure.

The recent retreat highlights ongoing structural pressure on Bitcoin investment vehicles in 2026. Overall, the spot Bitcoin ETF category remains approximately $1 billion short of reaching break-even for the year. Bitcoin was trading near $77,293.66, marking an 11.73% decline since Jan. 1 and a 33.48% drop over the past year. Despite drawing nearly $52 billion in cumulative capital since their initial regulatory launch, demand for Bitcoin funds weakened after an August price recovery lost momentum.

In contrast to both Ethereum and Bitcoin products, spot XRP ETFs generated $0.00 in net capital flow on Sept. 11, despite witnessing $36 million in secondary market trading volume during the session. The zero net flow figure indicates that secondary market transactions occurred entirely between individual accounts without prompting authorized participants to create or redeem underlying fund shares.

The flat creation-and-redemption performance highlights the relative novelty of XRP funds compared to their more established Bitcoin and Ethereum counterparts. Because market maker infrastructure for XRP ETFs remains in its early stages of development, the products lack the constant two-way liquidity flows routinely executed by institutional participants in Bitcoin funds.

To date, cumulative net inflows into XRP spot ETFs stand at $1.70 billion, while total net assets sit lower at $1.45 billion. The disparity reflects broader spot market declines, with XRP trading down 26.19% since the beginning of Jan. 1.

Market participants will be monitoring upcoming sessions to determine whether these shifts represent sustained trends across digital asset products. Ethereum ETFs will likely require several consecutive days of positive inflows to confirm lasting demand, while Bitcoin funds face a potential fifth day of outflows that could further solidify their current downward trajectory.
