Bitcoin Spot ETFs See $1.918B Inflows Last Week; BlackRock IBIT Leads

The concentration of flows in a single issuer is the real signal here: institutional demand is being expressed through the largest, most liquid regulated wrapper, which reinforces the ETF channel's role as the primary access point for traditional capital. That matters for how Bitcoin's ownership base is structured and for the competitive position of smaller issuers that struggle to capture share even when aggregate demand is strong. Whether inflows stay this concentrated, or broaden across providers, is the open question to watch.
