The Day's Outflows
US spot Bitcoin ETFs recorded $643 million in net outflows on Friday, October 30, according to Farside Investors. Five of the 12 funds in Farside's table reported withdrawals, and the other seven reported zero net flows, so no fund offset the redemptions with new money.
BlackRock's IBIT and Fidelity's FBTC were the two largest contributors to the day's negative total. Farside reports figures to the nearest $0.1 million.
Reversal of a Four-Day Run
The Friday withdrawals erased four consecutive sessions of inflows. The funds had taken in a combined $440.8 million from Monday through Thursday, October 26-29. With Friday included, the full week closed at a net outflow of $202.4 million, turning what looked like a recovery in the ETF channel into a weekly loss.
CryptoSlate framed the move as the second pullback in roughly a week, following an October 22 outflow it covered the previous week.
Wider Multi-Asset Picture
CoinDesk's reporting places the Bitcoin figures inside a broader pattern. It said Bitcoin, Ether, Solana and XRP exchange-traded products collectively shed $4.4 billion over 13 sessions, and that BlackRock's IBIT alone lost $342 million on Wednesday as ether, solana and XRP funds joined the redemptions. CoinDesk identified Hyperliquid's HYPE products as the only major crypto ETF category still taking in net new money.
The two outlets measure different windows and asset sets, so their totals are not directly comparable. CoinDesk's $4.4 billion covers 13 sessions across four assets, while CryptoSlate's $643 million covers a single day for US spot Bitcoin funds. Neither source's figures were reconciled against the other in the reporting provided.
Structural Context
These flows track one route into Bitcoin exposure: exchange-traded products that investors can hold through brokerage accounts without buying or storing the asset directly. The SEC permitted in-kind creations and redemptions for Bitcoin and Ether ETPs in July 2025, allowing authorized participants to exchange assets rather than relying solely on cash transactions. The source material does not state whether the in-kind mechanism affected the October 30 flows.
Why It Matters
For Traders
Friday's $643 million outflow erased the week's inflows, so near-term flow momentum into US spot Bitcoin ETFs has turned negative heading into the next session.
For Investors
Two consecutive weeks of pullbacks, and a multi-asset redemption wave per CoinDesk, suggest institutional demand through ETF wrappers is contested rather than one-directional.
For Builders
Products routing user capital through ETF wrappers face flow volatility, so protocols depending on ETF-linked liquidity should stress-test for sudden redemption-driven selling.
