Summary
On April 13, 2026, US spot Bitcoin and Ethereum ETFs recorded substantial net inflows, with Bitcoin ETFs adding 3,353 BTC and Ethereum ETFs receiving 29,225 ETH. This activity reflects sustained institutional demand for cryptocurrency-linked investment products, occurring within a broader context of accelerating ETF adoption among large asset managers and wealth advisers.
The April 13 inflows occurred amid a notable recovery period for cryptocurrency ETFs. Over the preceding week, US Bitcoin spot ETFs posted their strongest weekly performance since February 2026, accumulating more than $786 million in net inflows. SoSoValue data revealed that the weekly flow pattern was uneven, opening with a sharp $471.32 million intake on Monday before experiencing midweek outflows, then recovering substantially on Thursday and Friday. This pattern suggested that buyers reentered the market as Bitcoin regained momentum following earlier volatility.
BlackRock's iShares Bitcoin Trust dominated institutional inflows, capturing approximately $612 million—nearly 78% of total weekly inflows—underscoring the concentration of demand among the largest and most liquid Bitcoin ETF products. Additionally, Morgan Stanley's recently launched MSBT Bitcoin ETF added $46 million during its first three trading days, providing institutional investors with a new access point. Morgan Stanley's distribution network of approximately 16,000 financial advisers, overseeing trillions in client assets, positions this new product as a significant competitive entry into the ETF landscape, despite its early flows remaining modest relative to BlackRock's scale.
The April 13 inflows formed part of a broader positive momentum trend. March 2026 marked the first positive monthly inflow period for Bitcoin ETFs since October 2025, with $1.32 billion in cumulative inflows, indicating recovery in institutional appetite following prior periods of market stress and geopolitical tension that had weighed on risk appetite. Ethereum spot ETFs also demonstrated solid participation, with weekly inflows recorded at $187 million during comparable periods, suggesting institutional diversification across major cryptocurrency exposures.
