U.S. spot Bitcoin exchange-traded funds extended their winning stretch through Monday, March 17, 2026, posting six straight days of net inflows. That marked the longest uninterrupted inflow run since October 2025 and arrived alongside a sharp rebound in Bitcoin toward the $74,000 to $75,000 range.
The scale of the move was meaningful. Between March 9 and March 17, the ETF complex absorbed about $962.8 million in net inflows, including roughly $199.4 million on March 17 alone, showing that institutional demand had returned with noticeable force.
Capital Concentrated in the Biggest Vehicles
The flow picture was not evenly distributed across the full product lineup. Most of the new money moved into the largest and most established funds, rather than spreading broadly across all U.S. spot Bitcoin ETFs.
BlackRock’s iShares Bitcoin Trust remained the clear leader. IBIT brought in $139.4 million on March 17 and accounted for about $648.4 million of the $767 million collected during the five-day March 9–13 stretch, while Fidelity’s FBTC added another $64.5 million on March 17. Other issuers posted a mixed session, with modest inflows at some funds and outflows at others, including VanEck and ARK 21Shares.
That concentration says something important about how institutions are choosing exposure. The dominance of IBIT and FBTC suggests that liquidity, custody comfort, and operational familiarity continue to matter more than broad diversification across the ETF field.
Price Action Confirmed the Change in Tone
Bitcoin’s price moved in step with the stronger fund demand. During the inflow window, BTC rose from about $65,960 to roughly $74,250, a gain of just over 12% that pushed the market back toward six-week highs and into a key resistance band near $74,000 to $75,000.
The improvement was not isolated to Bitcoin alone. The same period also brought double-digit gains in major altcoins such as Ether, XRP, and Solana, reinforcing the sense that crypto markets had shifted back into a more constructive risk-on phase.
Analysts described the ETF streak as a practical sign of renewed institutional appetite. The inflow momentum, together with the move in price and the improvement in broader sentiment, helped pull the Crypto Fear & Greed Index out of the “extreme fear” zone during the reporting period.
A concentrated ETF bid at the same time Bitcoin is testing the $74,000 to $75,000 area increases the importance of watching short-term liquidity, derivatives basis, premium-discount behavior, and authorized participant activity across the largest funds.
