ETH Plunged 16% in October as Ethereum ETF Outflows Hit All-Time High

Spot Ether ETFs launched in the US in July 2024, a year and a half after spot Bitcoin funds opened the same door for institutional money. Through the summer of 2025 they built a three-month run of inflows, becoming a proxy for how large allocators were treating ETH alongside BTC. October broke that pattern outright: $1.61 billion left the funds, the worst month since the products debuted, undoing months of accumulated confidence in a single stretch.

For holders of ETHA and its peers, October meant redemptions outpacing new subscriptions on a scale authorized participants had not had to process before. BlackRock alone saw 580,145 ETH, about $1.32 billion, leave its fund, forcing the issuer to sell or unwind custody positions to meet redemptions. Traders watching fund flows as a sentiment gauge now have a harder signal to read, and anyone timing exposure to ETH through an ETF wrapper absorbed a month where the wrapper amplified, rather than cushioned, the asset's drop.

A 16% monthly decline arriving alongside record ETF withdrawals revives the argument that these products have made Ether's price more, not less, sensitive to institutional mood swings. That is the trade-off of wrapping a volatile asset in a vehicle built for traditional portfolios: it broadens access but also imports redemption mechanics that can compound a selloff. Whether spot ETFs smooth Ethereum's price discovery or sharpen its swings remains genuinely contested among market participants, and October gave ammunition to the skeptics.

Farside Investors' daily series showed $139.7 million leaving the funds on November 2 alone, with BlackRock's ETHA responsible for $138.3 million of it, meaning the October pattern had not reversed by the time November opened. The figures are provisional and subject to revision by data providers, so the next few days of daily prints will show whether outflows are decelerating or whether November is shaping up to extend, rather than close, October's record withdrawal run.
