Summary
US spot Bitcoin exchange-traded funds posted their strongest weekly inflow in nearly two months during the week of April 13, 2026, attracting $786 million across the category. This figure nearly matched the previous peak of approximately $787 million recorded in late February, signaling a meaningful recovery in institutional appetite after a prolonged quiet period marked by market volatility and geopolitical headwinds that had dampened risk sentiment.
BlackRock's iShares Bitcoin Trust remained the primary engine of demand, capturing approximately $612 million of the week's total inflows—nearly 80% of net category flows. This concentration reflects the dominant position of BlackRock's product as the largest and most liquid Bitcoin ETF vehicle, continuing to benefit from the firm's established institutional distribution network and $10 trillion in assets under management. The product has maintained consistent institutional interest since its launch at the start of 2024.
Flow patterns throughout the week revealed uneven momentum. Fund inflows opened strongly on Monday with $471 million, then deteriorated into outflows during midweek trading before recovering sharply on Thursday and Friday. This pattern suggested investors were recalibrating allocations in response to both price action and shifting macroeconomic conditions, ultimately pivoting back toward risk assets as Bitcoin regained momentum.
A secondary development of note was Morgan Stanley's launch of its spot Bitcoin ETF, the MSBT fund, which raised approximately $46 million over its initial three trading days. While modest relative to BlackRock's scale, the launch carries strategic significance given Morgan Stanley's distribution infrastructure—its network of approximately 16,000 financial advisers manages trillions in client assets, positioning the bank to reach a substantial investor base previously underexposed to direct Bitcoin ETF allocations.
The inflow surge underscores how institutional capital continues to gravitate toward spot Bitcoin products as a preferred mechanism for cryptocurrency exposure, with the largest and most liquid vehicles capturing the overwhelming majority of allocations. The rebound from weeks of outflows suggests that after periods of elevated risk aversion, institutional investors are incrementally resuming exposure to alternative assets as market conditions stabilize.
