Key Takeaways
  • • U.S. spot bitcoin ETFs recorded $186.1 million in net inflows on Wednesday, marking their second consecutive day of positive flows following a $411.5 million influx the prior session.
  • • Morgan Stanley's newly launched MSBT fund accumulated over $103 million in total net inflows within its first six trading days, surpassing WisdomTree Bitcoin Fund's cumulative $86 million total and establishing itself as a competitive entry in the bitcoin ETF landscape.
  • • BlackRock's IBIT led all products on Wednesday with $291.9 million in inflows, its largest single-day intake since early April, while the broader 13-fund group holds $97.6 billion in total net assets representing 6.5% of bitcoin's market capitalization.
  • • The spot bitcoin ETF complex has accumulated $57.1 billion in net inflows since January 2024 launch, demonstrating sustained institutional adoption despite mixed daily performance across individual funds.
  • • Bitcoin traded above $74,600 on Thursday, up 3% over the past week and 23% from its February 6 low near $60,000, though remaining 41% below the October 6, 2025 all-time high of approximately $126,000.
Summary
U.S. spot bitcoin ETFs continued their momentum with $186.1 million in net inflows on Wednesday, extending a streak of positive capital flows that underscores sustained institutional interest in cryptocurrency exposure through regulated vehicles. This inflow followed a notably stronger $411.5 million influx the prior trading session, demonstrating variable but directionally positive investor sentiment.

The standout performer was BlackRock's IBIT, which attracted $291.9 million—its largest single-day inflow since the beginning of April. Morgan Stanley's recently debuted MSBT ranked second with $19.3 million on the day, but the fund's early trajectory has proven particularly noteworthy. Within just six trading days of its market launch, MSBT accumulated over $103 million in cumulative net inflows, exceeding the all-time total of $86 million held by WisdomTree Bitcoin Fund, according to Farside data. This rapid competitive displacement signals meaningful investor appetite for Morgan Stanley's offering in an increasingly crowded bitcoin ETF marketplace.

The flow picture remains bifurcated across the 13-fund complex. While only two funds posted positive flows on Wednesday, eight recorded zero net flows, and significant outflows emerged elsewhere. Fidelity's FBTC experienced $47.4 million in redemptions, while Ark Invest and 21Shares' ARKB saw $42.2 million in outflows and Grayscale's GBTC posted $23.4 million in redemptions. Smaller outflows were recorded from Bitwise's BITB ($8.5 million) and VanEck's HODL ($3.7 million). Cumulatively, the 13-fund group holds $97.6 billion in total net assets as of April 15, representing approximately 6.5% of bitcoin's total market capitalization and reflecting $57.1 billion in net inflows since the product suite launched in January 2024.

Bitcoin itself traded above $74,600 on Thursday, reflecting modest upward momentum with a 3% gain over the past week and a 23% advance from its February 6 low near $60,000. However, the cryptocurrency remains materially depressed relative to its October 6, 2025 all-time high of approximately $126,000, trading 41% below that peak. The price action suggests investors are reassessing bitcoin valuations against macro conditions while institutional capital continues flowing into regulated ETF vehicles as a preferred custody and trading mechanism.
