BlackRock Bitcoin ETF Smashes $269M in Single Day—Strongest Inflow Since Early March

Institutional appetite for spot Bitcoin ETFs just showed real teeth. BlackRock's iShares Bitcoin Trust (IBIT) pulled in $269.3 million on Thursday—its best day in five weeks—signaling renewed conviction among large investors even as Bitcoin pulled back from its $97,000 peak.

The move broke a two-day outflow streak across the 12 US spot Bitcoin ETFs, with the broader ecosystem recording $358.1 million in net inflows for the day. This matters because ETF flows are a direct window into how institutional and retail capital is actually voting on Bitcoin's direction—and right now, the big players are buyers.

The Full ETF Scorecard

Fidelity's Wise Origin Bitcoin Fund (FBTC) came in second with $53.3 million, while Morgan Stanley's brand-new Bitcoin Trust (MSBT) posted $14.9 million on just its second trading day. Bitwise and ARK 21Shares combined for $16.5 million, with Franklin Templeton and VanEck adding another $2 million. That's nine Bitcoin ETF products all moving inflows in the same direction on the same day—a chorus of institutional demand.

Morgan Stanley's digital assets head Amy Oldenburg called MSBT "the institutional bank's best-performing ETF launch ever" during a Bloomberg interview Thursday. She signaled this is just the opening act: "This is just the first of a long roadmap of new products on the asset management side." The bank has already filed for spot ETH and Solana ETF approvals, which tells you everything about where these institutions see the crypto market heading.

The Bigger Picture: BlackRock's Sticky Capital

BlackRock's IBIT has accumulated $1.5 billion in net inflows since January 1st, a jaw-dropping number given that Bitcoin crashed from $97,000 to $72,100 during the same period. This isn't luck—it's a direct reflection of what BlackRock's Robert Mitchnick noted back in March: IBIT investors are "disproportionately long-term buy and hold" investors who don't panic during volatility. Institutional capital is different from retail chasing momentum.

The timing of this $269M inflow matters too. It lands when Bitcoin is off its highs and skeptics are loudest, which is precisely when conviction capital shows up.

The Year-to-Date Reset

Here's the setup: US spot Bitcoin ETFs finished 2025 with $56.59 billion in net inflows. They're currently sitting at $56.51 billion—just $80 million below that mark. In other words, these products are on the verge of returning to net inflow territory for the year despite the recent pullback. A few more days like Thursday, and we're back to relentless institutional accumulation narrative.
