BlackRock recorded nearly $1.01 billion in Bitcoin sales over the past week, marking its largest weekly Bitcoin reduction since November 2025, according to Arkham Intelligence data. The sell-offs coincided with $1.26 billion in combined outflows from U.S. spot Bitcoin ETFs, representing the largest weekly outflow for 2026. As reported by Arkham Intelligence, BlackRock sold Bitcoin every trading day during the week, accounting for most of the capital leaving the sector during a sharp downturn across crypto markets. However, recent analysis suggests these transactions reflected routine ETF redemption activity rather than BlackRock fully abandoning its long-term Bitcoin strategy.
The latest outflows occurred as 30-year Treasury yields climbed to 5.197%, the highest level since 2007, while Japan, the U.K., and Germany all saw their long-end bonds break through multi-decade highs simultaneously. On May 13, hot U.S. inflation data landed and Bitcoin ETFs recorded $635 million in outflows in a single day - the largest since January. According to market analysts, portfolio managers with Bitcoin exposure bought as a growth option rather than a bond substitute are conducting spreadsheet calculations when alternatives improve. The selling was particularly concentrated, with $635.23 million in single-day ETF redemptions on May 13 alone, representing the biggest exit since January.
Several analysts and market trackers linked the ETF withdrawals to defensive positioning by institutional investors as uncertainty continued to weigh on digital assets. As reported by Arkham Intelligence, institutions appear to be reducing exposure amid concerns that bearish momentum in Bitcoin could deepen if macroeconomic conditions worsen. The decline in ETF demand comes after months of strong inflows that helped push Bitcoin toward new highs earlier this year, with recent outflows indicating some large investors are choosing to rotate capital away from crypto-linked products while waiting for clearer market direction. Funds tracking Bitcoin have shed more than $1.5 billion since mid-May as investors pulled capital from several of the largest crypto investment products. However, the outflow week came after about $2 billion in net inflows in April and a six-week inflow streak, making the reversal look less like a structural collapse in demand and more like a fast reset after optimism had built up quickly.
Despite trimming Bitcoin exposure through its ETF operations, BlackRock continues expanding into blockchain-based financial products elsewhere. The asset manager recently filed a second tokenized fund application with the U.S. Securities and Exchange Commission using infrastructure developed by Securitize. The filing follows the rapid growth of BUIDL, BlackRock's tokenized U.S. Treasury fund launched with Securitize in March 2024, which has grown to around $2.3 billion in assets and currently stands as the largest tokenized Treasury fund globally.
The latest withdrawals signal a slowdown in institutional momentum after months of aggressive accumulation, with some large financial firms already scaling back exposure this year. Trading firm Jane Street significantly reduced its Bitcoin ETF positions during the first quarter, while Harvard also trimmed holdings, according to recent filings. During the same week of outflows, Morgan Stanley's Bitcoin ETF (MSBT) recorded the only net inflow among major funds - a modest $1.1 million. Since spot Bitcoin ETFs launched, they've pulled in approximately $58.5 billion in cumulative net inflows and now manage roughly $102 billion in assets. The ETF product structure allows for frictionless entry and exit, meaning the exit door is as wide as the entrance when liquidity conditions tighten. The question now is whether the current outflows reflect purely mechanical yield rotation or deeper institutional recalibration of Bitcoin's portfolio role.
