Key Takeaways
- • US spot Bitcoin ETFs recorded $442.62 million in net outflows during the week of October 19 to 23, 2026, while spot Ethereum ETFs gave up $224.96 million over the same period.
- • Bitcoin ETFs posted a single-day outflow of about $635.5 million on October 22, the largest single-day exit since June 2026, which wiped out earlier-week gains.
- • Ethereum ETF outflows extended a multi-week run of weekly redemptions, signaling more persistent exposure reduction than the Bitcoin single-session shock.
- • BlackRock's iShares Bitcoin Trust (IBIT) led the category in both inflows and outflows, and its flows can swing the category's weekly total in either direction.
- • Cumulative net inflows into Bitcoin ETFs remain above $57 billion, and the weekly outflow equals well under 1% of the roughly $104 to $105 billion in Bitcoin ETF assets.
Summary
US spot Bitcoin ETFs recorded $442.62 million in net outflows during the week of October 19 to 23, 2026, a period of heightened market volatility, according to TradingView. Spot Ethereum ETFs shed $224.96 million over the same stretch. The bulk of the Bitcoin pressure came on October 22, when the funds saw a single-day outflow of roughly $635.5 million, the largest such session since June 2026. That one day largely erased the gains the funds had accumulated earlier in the week.
Ethereum ETF outflows followed a different pattern. The $224.96 million weekly figure was not a one-off spike but extended a run of weekly outflows that has spanned multiple weeks, suggesting some Ether ETF holders are reassessing their exposure rather than reacting to a single volatile session. Because total Ethereum ETF assets are around $14.5 billion, the weekly outflow represents a proportionally larger share of the category than Bitcoin's outflow does of its roughly $104 to $105 billion base.
BlackRock's iShares Bitcoin Trust (IBIT) sat at the center of the activity, leading the category in both inflows and outflows during the period. Fidelity was also among the key issuers with fluctuating participation. IBIT has accumulated approximately $65 to $66 billion in net inflows since launch, while Grayscale's GBTC has recorded around $28 billion in cumulative outflows. Because IBIT is the largest fund, its flows can swing the category total meaningfully, so the headline weekly figure often reflects BlackRock client activity as much as broader market sentiment.
Despite the recent outflows, the long-term ledger for Bitcoin ETFs remains positive. Cumulative net inflows since debut exceed $57 billion, and the $442.62 million weekly outflow is well under 1% of category assets. Daily flow data in the coming weeks will indicate whether the October 22 exit was an isolated event or the start of a broader trend.
