Why this matters

The flow split shows that institutional demand remained concentrated in BlackRock’s IBIT even as the broader spot Bitcoin ETF category recorded only a modest net weekly gain. With $102.53 billion in total net assets, shifts among major issuers could influence Bitcoin market liquidity and how investors assess ETF-provider concentration.
