Bitcoin and Ethereum ETFs See $1.1B Inflows in Biggest Week Since 2026; Institutional Accumulation Broadens

BlackRock IBIT gobbling 80% of BTC flows, low volume suggests cautious accumulation. Flips persistent outflows narrative. BlackRock slashed IBIT swap minimum from $25M to $1M, enabling more institutional flow without selling pressure. JPMorgan boosted BTC ETF stake 25% and quadrupled ETH ETF holdings; Morgan Stanley also increased IBIT share count. Harvard and Abu Dhabi hold steady despite $5.4B H1 outflows, confirming long-term conviction. Actionable for macro positioning and ETF rotation.
