US Spot Bitcoin ETFs Log $228.6 Million in Weekly Outflows as October Total Nears $618 Million
Key Takeaways
- •Investors withdrew $228.6 million from US spot Bitcoin ETFs over the five trading days ending October 16, 2026, pushing month-to-date net outflows to roughly $615-618 million.
- •BlackRock's iShares Bitcoin Trust led the week's redemptions with approximately $165 million in exits, including $71.8 million on October 16, while Fidelity's Wise Origin fund recorded $10.6 million in outflows that day.
- •The largest single-day outflow occurred on October 7, when $487.1 million left the funds, representing roughly 80% of the month-to-date total.
- •Since their January 2024 launch following SEC approval, the funds have drawn approximately $56.88 billion in cumulative inflows and hold about $104.29 billion in assets, meaning October's outflows are well under 1% of assets under management.
- •Because spot ETFs hold Bitcoin directly, each redemption can require issuers to reduce their Bitcoin or cash positions, allowing outflows to translate into actual selling in the underlying market.
US spot Bitcoin exchange-traded funds (ETFs) recorded a sustained stretch of redemptions in October 2026, with investors withdrawing $228.6 million over the five trading days ending October 16, 2026. That brings month-to-date net outflows to roughly $615 million, with some tallies placing the figure closer to $618 million.
The funds have become the main on-ramp for institutional money entering Bitcoin, and periods in which exits outpace entrances tend to draw close attention.
Where the Outflows Concentrated
BlackRock's iShares Bitcoin Trust (IBIT) led the retreat. The fund saw approximately $165 million leave during the week, including $71.8 million on October 16 alone.
Fidelity's Wise Origin Bitcoin Fund (FBTC) also posted outflows on October 16, though its share was smaller, at $10.6 million.
The sharpest single-day hit landed on October 7, when outflows peaked at $487.1 million. That one session represents a large portion of the entire month's net total so far — roughly 80% of the month-to-date figure.
Trading activity stayed busy throughout the period. Daily volume across the funds exceeded $2 billion on multiple sessions during October.
The Bigger Picture Since January 2024
US spot Bitcoin ETFs launched in January 2024 following approval from the US Securities and Exchange Commission, and cumulative inflows since then have reached approximately $56.88 billion. Total assets under management across the funds stood at $104.29 billion as of mid-October, meaning the month's outflows represent well under 1% of that figure.
The funds collectively hold roughly 1.276 million BTC.
Redemptions are not merely an accounting entry. Because spot ETFs hold Bitcoin directly rather than through derivatives, every share redeemed can require an issuer to reduce its Bitcoin holdings or its cash position, which means outflows can translate into actual selling in the underlying market.
What This Means for the Market
With IBIT and FBTC leading redemptions, the exits are concentrated in the largest and most institutionally oriented products.
The outflows do not necessarily indicate that institutions have lost faith in Bitcoin. A week of redemptions can reflect rebalancing, profit-taking, or shifting allocations across a broader portfolio, rather than a verdict on the asset itself.
The October 7 session stands out. A $487.1 million single-day exit shows how quickly positioning can swing, and how much capital can move in one direction when it does.
Sustained trading volume above $2 billion on multiple sessions is worth tracking alongside the flow data. Engagement remains high which means the funds are still a central venue for Bitcoin exposure even when the net direction is negative.
Key data points to watch include whether IBIT's redemptions slow or accelerate, whether the month-to-date total climbs meaningfully beyond the $618 million mark, and how the funds' combined holdings of roughly 1.276 million BTC hold up.
