US-listed spot Bitcoin ETFs extended their losing streak Wednesday, with $133.3 million in net outflows, as crypto sentiment remains in “Extreme Fear” and BTC briefly slipped below $66,000.According to data from SoSoValue, total weekly outflows have now reached $238 million. BlackRock’s iShares Bitcoin Trust (IBIT) led the withdrawals, seeing more than $84 million exit in a single day.If outflows continue through the end of the week, this would mark the first five-week streak of net redemptions for US spot Bitcoin ETFs since March 2025.ETF Assets Shrink as Trading Activity SlowsYear-to-date, Bitcoin ETFs have recorded roughly $2.5 billion in net outflows, bringing total assets under management down to approximately $83.6 billion.Trading volumes also remained subdued at under $3 billion, reflecting muted investor participation despite earlier expectations that slowing outflows could signal a near-term inflection point.Solana ETFs Defy Broader TrendWhile Bitcoin, Ether, and XRP ETFs posted daily losses—$41.8 million in Ether and $2.2 million in XRP outflows—Solana ETFs continued to attract capital.US spot Solana ETFs have now logged a six-day inflow streak, with around $113 million added year-to-date. Since launching in October 2025, Solana funds have accumulated nearly $700 million in assets, though monthly inflows have cooled compared to late 2025 highs.Sentiment Remains in ‘Extreme Fear’Market sentiment continues to weigh on flows. The Crypto Fear & Greed Index remains entrenched in the “Extreme Fear” zone, even after Bitcoin rebounded from early February lows near $60,000.At the time of writing, Bitcoin traded around $67,000 on Coinbase, down roughly 24% year-to-date.Despite persistent ETF outflows and weak sentiment, some analysts argue that current risk-adjusted metrics—such as Bitcoin’s short-term Sharpe ratio—are approaching levels historically associated with major buying opportunities.Still, with derivatives positioning elevated and macro uncertainty lingering, ETF flows remain a key indicator of whether institutional demand will stabilize or extend the current retracement phase.
