BlackRock just reminded everyone who’s boss in the Bitcoin ETF space. On April 28, 2025, its iShares Bitcoin Trust (IBIT) quietly scooped up a massive $970 million worth of Bitcoin in a single day.
That’s the second-largest inflow ever for the fund, only behind the monster $1.12 billion it pulled in last November. This also brings BlackRock’s market share dominance to over 50% for Bitcoin ETFs.

With this buy, IBIT now holds over $56 billion in assets. To put that in perspective, that’s more than 3% of Bitcoin’s total supply. One fund, managed by the world’s biggest asset manager, is sitting on enough BTC to make even some crypto OGs raise an eyebrow.
BlackRock Bitcoin ETF: Market Dynamics and Institutional Interest
While BlackRock was busy loading up, most other U.S. spot Bitcoin ETFs had either flat flows or even outflows on the same day. That contrast is hard to ignore and raises the question: what does BlackRock see that others might be missing?
Some analysts say it all comes down to timing and strategy. Big buys like this are seen as providing structural support for Bitcoin. When someone like BlackRock makes a move, it helps put a floor under the price. That kind of stability is gold to investors in a space known for wild swings.

Samara Cohen, BlackRock’s CIO of ETF and Index Investments, chimed in recently to say that most institutional clients are laser-focused on Bitcoin right now. It makes sense. With markets unsure about rates, inflation, and global tension, Bitcoin is starting to look more like a long-term play than a moonshot bet.
Bitcoin’s Price Stability Amid Market Movements
Surprisingly, despite BlackRock’s billion-dollar move, Bitcoin didn’t leap overnight. Instead, it stayed steady at around $95,000. That kind of calm after a big buy is a sign of how much the market has matured.

At the same time, other top tokens like Ethereum and Cardano also saw some green. The broader market is showing signs of confidence, even if no one is throwing a party just yet.
Looking Forward
BlackRock’s latest move is not just a flex. It’s a signal that institutional investors are here to stay and are doubling down on Bitcoin even as others hesitate. The fact that this happened while rival ETFs sat still or saw outflows says a lot.
Whether you are a long-term holder or just watching from the sidelines, one thing is clear: Bitcoin’s ETF race is heating up, and BlackRock is leading the charge. The question now is who follows next and how fast the game changes.
