U.S. spot Bitcoin exchange-traded funds recorded approximately $467.3 million in net inflows during Tuesday’s trading session, extending a multi-day streak of institutional buying as investors increased exposure following Bitcoin’s recovery above the $81,000 level.
The latest session marked the fourth consecutive trading day of positive flows for spot Bitcoin ETFs and followed inflows of roughly $532.3 million on Monday and $629.8 million on May 1. Combined inflows across the past four trading sessions now exceed $1.64 billion, according to ETF flow data compiled by Farside Investors.
BlackRock continued to dominate institutional allocations through its iShares Bitcoin Trust (IBIT), which attracted approximately $251.4 million in net inflows during Tuesday’s session. Fidelity Investments followed with $133.2 million in inflows through FBTC, while ARK 21Shares Bitcoin ETF added roughly $92.3 million. Bitwise’s BITB attracted an additional $14.6 million.
The only notable outflow came from Grayscale Investments’s GBTC, which recorded approximately $18.4 million in net redemptions.
Analysts said the renewed inflow momentum suggests institutional investors are continuing to treat recent Bitcoin price weakness as an accumulation opportunity rather than a broader reversal in market structure. Bitcoin traded above $81,000 during Tuesday’s session after recovering from sharp corrections seen earlier this quarter.
Bitcoin ETFs Continue to Outperform Ethereum Products
While Bitcoin ETFs experienced strong inflows, Ethereum ETFs continued to show weaker institutional demand. Recent flow data indicated Ethereum spot ETFs recorded approximately $82.4 million in net outflows earlier this week, reflecting continued divergence between institutional Bitcoin and Ether positioning.
Market analysts noted that Bitcoin continues to attract stronger spot ETF allocations relative to Ethereum, reinforcing elevated Bitcoin dominance levels across the broader digital asset market. Institutional investors have increasingly concentrated exposure around Bitcoin products as regulatory clarity and liquidity conditions continue to favor the asset.
According to ETF flow trackers, BlackRock’s Ethereum ETF products remain among the few Ether funds consistently attracting positive allocations, while several competing products continue to experience intermittent outflows.
The divergence between Bitcoin and Ethereum flows has become more pronounced during recent weeks despite broader recovery across digital asset markets. Analysts attributed the gap partly to Bitcoin’s stronger institutional positioning as a macro asset and reserve allocation vehicle compared with Ethereum’s more technology-focused investment narrative.
Institutional Positioning Remains Central to Market Structure
ETF flows remain one of the most closely watched indicators for institutional sentiment within crypto markets. Since the approval of U.S. spot Bitcoin ETFs, fund flows have increasingly shaped short-term market liquidity, volatility, and directional price momentum.
Cumulative net inflows across spot Bitcoin ETFs now total approximately $59.75 billion, according to aggregated market data. BlackRock’s IBIT alone has attracted more than $66 billion in cumulative inflows since launch, significantly outpacing competing products.
Analysts said the current inflow streak suggests institutional appetite for Bitcoin exposure remains resilient despite macroeconomic uncertainty and broader market volatility. At the same time, the concentration of inflows into a small number of dominant ETF issuers continues reshaping liquidity dynamics within the digital asset market.
Market participants are now closely monitoring whether inflows can sustain current momentum as expectations around Federal Reserve policy, crypto regulation, and additional digital asset ETF approvals continue influencing institutional allocation decisions.
