As of Q2 2026, 47 SEC-registered investment managers reported holding AON (AON PLC) in their latest 13F filings, with a combined reported value of $28.39B across 88.62M shares. That is +2.2% by share count (+1.91M shares) versus the previous quarter, while reported value moved +2.8%.

Compared with the prior quarter, 2 opened new positions, 19 added to existing stakes, 24 trimmed, 4 exited entirely. 13F holdings are quarter-end snapshots, so these moves reflect positioning as of Q2 2026, not real-time trading.

AON is a constituent of the S&P 500 and is classified in the Financials sector.

All figures on this page are computed from SEC Form 13F quarterly filings. 13F filers disclose long positions of $100,000 or more within 45 days of quarter end; short positions, options overlays and intra-quarter trades are not included, so treat the numbers as a quarterly snapshot of institutional ownership rather than real-time positioning.
