Q2 2026 ETF Flow Summary
Total US ETF net inflows reached $265B in Q2 2026, the second-highest quarterly figure on record after Q1 2024. BlackRock's iShares platform led with $98B in net inflows, driven by the iShares Core S&P 500 ETF (IVV), the iShares Bitcoin Trust (IBIT), and the iShares 20+ Year Treasury Bond ETF (TLT). Vanguard's $76B in net inflows was concentrated in the Vanguard Total Stock Market ETF (VTI), Vanguard S&P 500 ETF (VOO), and Vanguard Total Bond Market ETF (BND).
Active ETF Battle
The fastest-growing segment of the ETF market is actively managed ETFs, where fund managers make discretionary decisions rather than tracking an index. In Q2 2026, active ETFs captured $48B of the total $265B in flows — 18% of the market despite representing only 6% of total ETF assets. BlackRock leads this segment with a 34% market share of active ETF assets, driven by its acquisitions of active management capabilities and the launch of its Capital Group partnership ETFs. Fidelity holds 22% of the active ETF market and is the fastest-growing major player, while Vanguard at 8% remains a minor participant.
Fee Compression Continues
Average ETF expense ratios continued declining in Q2 2026. Vanguard's asset-weighted average expense ratio is 0.07%, an industry low. BlackRock's iShares average is 0.16%. The zero-fee and near-zero-fee ETF category — pioneered by Fidelity with its ZERO index funds — has grown to $89B in total assets. Morgan Stanley estimates that annual fee revenue lost to expense ratio compression across the industry now runs at approximately $3B per year, a structural headwind for smaller ETF providers.
Institutional vs Retail Flows
Goldman Sachs' ETF analytics team found that institutional investors (pension funds, endowments, insurers) accounted for 58% of Q2 2026 ETF inflows — a new high. Retail investor flows, while positive, have moderated from the peak engagement of 2020-2021. The institutionalisation of ETF usage reflects the shift of pension funds from individual securities and mutual funds to ETF-based portfolio construction.
