US Spot Bitcoin ETFs Post $635M Single-Day Outflow, Turning October Net Negative

A single session of heavy redemptions erased three weeks of inflows, leaving the US spot Bitcoin ETF complex with a net monthly loss of $175 million and raising questions about near-term...

US-listed spot Bitcoin exchange-traded funds recorded net outflows of $635 million on Thursday, October 23, 2026, according to CoinTelegraph. The single-session withdrawal ended a three-day consecutive inflow streak and pushed the collective October balance for the US spot Bitcoin ETF category into net negative territory.

The net outflow figure for October now stands at $175 million, per the same CoinTelegraph report. That means the $635 million redemption day was large enough to reverse what had been a positive monthly trend across the complex, which includes products from issuers such as BlackRock, Fidelity, and Invesco, all of which file holdings data with the US Securities and Exchange Commission.

Spot Bitcoin ETFs were approved for US trading by the SEC in January 2024, following years of regulatory denials. The products allow investors to gain exposure to Bitcoin's price through a standard brokerage account without holding the underlying asset directly. That structure attracted billions of dollars in net inflows during their first several months of trading, according to SEC-filed prospectus and flow data published by Bloomberg Intelligence at the time.

The mechanics of an ETF outflow involve authorized participants, typically large broker-dealers, redeeming creation units in exchange for the underlying asset or cash equivalent. When net redemptions exceed net creations on a given day, the fund complex as a whole shrinks in assets under management. Whether Thursday's outflow reflects a change in institutional positioning, tax-related selling, or portfolio rebalancing is not determinable from publicly available flow data alone. Full 13-F filings, which institutions holding more than $100 million in assets must submit to the SEC quarterly, would reveal more about the nature of holders, though those filings lag by up to 45 days.

The $635 million figure places Thursday among the larger single-day outflow events in the short history of US spot Bitcoin ETFs. For context, the previous record single-day outflow for the category was approximately $563 million, recorded in late April 2024, according to data cited by Bloomberg Intelligence at that time. If Thursday's number is confirmed by issuer-level data, it would represent the largest single-session net outflow since the products launched.

Bitcoin's spot price movement on the day was not specified in the CoinTelegraph report, and it is unknown from the available source material whether the outflows preceded or followed intraday price action. Price data for Bitcoin on US exchanges is publicly available through sources including the CME CF Bitcoin Reference Rate and Coinbase Global's reported trade data filed with Nasdaq.

The October reversal is notable because prior months had shown sustained inflow periods that analysts at firms including JPMorgan and Standard Chartered had cited as evidence of growing institutional adoption, per their separately published research notes. The current net outflow of $175 million for October does not by itself indicate a reversal of that longer-term trend, but it does interrupt what had been a broadly constructive inflow pattern through mid-October.

For US retail and institutional investors, the practical effect of large outflows depends on their own position size and holding period. ETF investors who did not redeem shares are not directly affected by others' redemptions in terms of their own unit count, though sustained large outflows can affect a fund's liquidity profile and, in some structures, its expense ratio economics over time.

The US spot Bitcoin ETF complex remains a closely watched indicator of institutional sentiment toward digital assets, given that the products operate under SEC oversight and require daily disclosure of net asset values. The next scheduled flow data update, covering Friday's session, will indicate whether Thursday's outflow was an isolated event or the beginning of a sustained redemption period. That data will be published by individual fund sponsors and aggregated by financial data providers including Bloomberg and Morningstar.
