Ethereum and Bitcoin spot ETFs experienced a combined $376 million inflow on September 18, 2025, with Ethereum funds attracting the larger share, highlighting growing institutional interest.

Lede: Ethereum and Bitcoin spot ETFs drew substantial inflows of $376 million on September 18, 2025. This influx indicates a strong institutional appetite towards these crypto assets, particularly as Ethereum ETFs exceeded Bitcoin in attracting investments for that day. “Ethereum ETFs outpaced Bitcoin with $213M inflows on 2025/9/18, reversing prior outflows amid growing institutional confidence.” Major players involved were Fidelity and Grayscale, with Fidelity’s FETH leading Ethereum inflows. SEC’s new rules facilitated the rise of such commodity ETFs, underscoring changes in capital allocations by institutional investors.
Immediate effects included a 1.7% rise in ETH and a 0.3% increase in BTC prices. The CoinDesk 20 index reflected a 2% growth due to this inflow activity. The financial implications extend to increased Ethereum ETF AUM now holding 5.49% of the market cap. Ethereum ETFs benefited from recent DeFi upgrades and technical momentum.
Ethereum’s inflows might drive further institutional diversification beyond a Bitcoin-dominant focus. This trend could eventually influence DeFi-related tokens, potentially enhancing cross-chain protocol investments. Historical trends suggest a correlation between SEC’s regulatory moves and ETF inflows, further impacting crypto market dynamics and strategic asset allocation within investment portfolios.
