  • • Weekly inflows into spot Bitcoin ETFs reached nearly $1 billion ($996 million) in the most recent reporting period, marking the strongest weekly performance since early January and indicating accelerating institutional demand.
  • • BlackRock's IBIT leads individual fund performance, consistently attracting the largest inflows; Morgan Stanley's newly launched MSBT has rapidly gained institutional adoption, surpassing established competitors like WisdomTree's Bitcoin Fund within one week.
  • • Daily inflows averaged $663.9 million on peak days, with total trading volumes climbing above $4.8 billion daily as institutional capital rotates into Bitcoin amid de-escalation of geopolitical tensions and dollar weakness.

Summary
US spot Bitcoin ETFs are experiencing sustained momentum in 2026, with year-to-date net inflows surpassing $1 billion and cumulative inflows reaching $57.08 billion. Total net assets under management have climbed to $97.9 billion, placing the sector on the cusp of breaking through the $100 billion threshold. This milestone reflects the maturation of Bitcoin as an institutional asset class, with traditional financial firms integrating spot Bitcoin exposure into core cryptocurrency strategies.

Recent weekly performance underscores accelerating demand, with spot Bitcoin ETFs attracting $996 million in net inflows over a seven-day period—the strongest weekly intake since early January. Market analysts attribute this surge to shifting geopolitical risk sentiment, particularly reduced tension in US-Iran relations, which has weakened safe-haven demand for the US dollar and redirected capital into alternative assets including Bitcoin. Daily inflows reached $663.9 million on peak trading days, accompanied by elevated trading volumes exceeding $4.8 billion daily.

BlackRock's IBIT remains the dominant fund by inflows, recording $81.71 million in a single trading session and capturing substantial institutional demand. Morgan Stanley's recently launched MSBT spot Bitcoin ETF has demonstrated rapid market penetration, surpassing the WisdomTree Bitcoin Fund in cumulative net inflows within one week of launch—a significant competitive achievement in an increasingly crowded product landscape. Additional inflows flowed to Grayscale's mini trust BTC ($16.67 million) and Morgan Stanley's offering ($13.36 million), though outflows were recorded at Fidelity's FBTC ($35.99 million), Ark Invest and 21Shares' ARKB ($27.41 million), and Grayscale's GBTC ($22.28 million).

Notably, institutional demand has concentrated almost exclusively in Bitcoin, with March 24 data showing Bitcoin ETFs capturing $167.23 million in inflows while Ethereum ETFs recorded $16.18 million in outflows—a bifurcation reflecting active reallocation rather than uniform cryptocurrency exposure. BlackRock alone accounted for 96% of total Bitcoin ETF inflows on that session with 2,270 BTC ($160.89 million), demonstrating the dominant role of mega-cap asset managers in driving institutional crypto adoption.
