Asset manager ETF AUM measures the client assets reported inside an asset manager's exchange-traded fund products.

BlackRock reported $6.246T of ETF AUM at June 30, 2026, up from $5.468T at December 31, 2025.

ETF AUM is a product-mix measure, not total company AUM

ETF assets sit inside BlackRock's broader AUM base alongside active strategies, non-ETF index products, private markets, and cash management.

A growing ETF balance can therefore change the company's fee mix even when total AUM grows at a different rate.

Market appreciation and client flows both change ETF AUM

The ending balance reflects net inflows, market moves, foreign exchange, and other stated AUM bridge effects.

Read it with ETF net inflows and base-fee revenue growth.

Recurring, variable, and technology monetization
Base fees, securities lending, performance fees, and technology subscriptions represent distinct revenue engines with different relationships to AUM, markets, lending demand, investment performance, and software adoption.
