Bloomberg ETF analyst Eric Balchunas reported year-to-date ETF inflows into U.S. ETFs have surpassed $800 billion, averaging about $5 billion per day and projecting to roughly $1.2 trillion for the year — a level that would represent a record annual total. His published data shows Vanguard’s S&P 500 ETF (VOO) leading with a net inflow of $86.1 billion, while BlackRock IBIT ranks fifth with $21.49 billion and BlackRock ETHA sits 12th with $9.287 billion year-to-date. These concentration dynamics underscore evolving passive allocation patterns and warrant attention from portfolio managers assessing equity and crypto-related ETF exposures.
