CapitolRadar analysis
76 tracked trades skew toward sales
76 trades in Aon plc were tracked from March 13, 2019 through April 6, 2026: 30 buys and 46 sells by five distinct traders. That is 16 more sells than buys across the full period. The participant count is small, so the totals should not be interpreted as broad congressional consensus about AON or the Financial Services / Insurance - Brokers industry.
30 trades appear across the eight listed quarters from 2024 Q3 through 2026 Q2, including 15 buys. Activity peaked in 2024 Q3 at eight trades, all buys. The next seven quarters were more mixed: 2024 Q4 had two buys among three trades; 2025 Q1 and Q2 recorded no buys across seven combined trades; 2025 Q3 and Q4 each had two buys among three trades; 2026 Q1 had one buy among five trades; and 2026 Q2 had one trade and no buys.
23 of 30 buys came from Ro Khanna
Ro Khanna accounted for 23 buys, with the latest dated January 13, 2026. Michael McCaul recorded five buys, most recently June 6, 2024. Tommy Tuberville had one buy dated October 17, 2023, while Lois Frankel had one dated March 13, 2019. These four named buyers account for all 30 tracked AON purchases, but the small number of buyers—and Khanna’s large share of purchases—limits what can be inferred from the aggregate.
Six overlapping holdings involved two buyers each
Two AON buyers each also bought AJG, INTU, TER, BSX, DHR and MA. These overlaps show repeated names within the disclosed portfolios, but the data do not establish timing relationships, strategy or motive.
Congressional transaction reports can be filed up to 45 days after a trade, so disclosure dates may lag the underlying activity. Reported transaction amounts are typically disclosed as ranges, making dollar values estimates rather than exact figures; no amount ranges are provided here.
