Spot Bitcoin ETFs Post $1.42B Weekly Outflow, Third-Largest on Record

US spot Bitcoin ETFs logged $1.42 billion in net outflows last week, marking the third-largest weekly withdrawal since the products debuted. The selling wasn't a one-off: it was the third straight week of sizable redemptions, lifting three-week net outflows above $3.5 billion. BlackRock's iShares Bitcoin Trust (IBIT), the largest spot Bitcoin ETF by assets, drove most of the move. IBIT saw about $966 million leave over the week, including a single-day peak of roughly $448 million in redemptions. Across the category, spot Bitcoin ETFs were net sellers of around 19,021 BTC for the week—about the equivalent of 42 days of newly mined Bitcoin supply hitting the market at once. Bitcoin prices reflected the pressure, trading in a $73,500 to $76,900 range over the period. The Crypto Fear & Greed Index remained in "fear" territory, consistent with cautious sentiment among traders. Rising US Treasury yields have been a key headwind, increasing the appeal of risk-free government bonds versus volatile assets such as crypto. Geopolitical tensions have added to uncertainty. When investors redeem ETF shares, issuers typically meet cash outflows by selling underlying Bitcoin, a feedback loop that can amplify downside pressure and trigger additional redemptions. Even so, spot market demand absorbed part of the ETF selling, helping limit the drawdown. The concentration of outflows in IBIT is closely watched because the fund has been a bellwether for institutional participation since spot ETFs launched. With more than $3.5 billion exiting the group in three weeks, sustained outflows could test the $73,000 support level that has held during the recent trading range. At the same time, the market's ability to digest 19,021 BTC without a sharp break suggests underlying bid support remains in place.
