In plain English
Aon is one of the world's two giant insurance brokers. It doesn't carry risk itself — it sits in the middle, helping big companies figure out, price and buy protection: placing their insurance with carriers, ceding their biggest tail risks to reinsurers, and advising on pensions, health benefits and retirement. After the US blocked its mega-merger with Willis Towers Watson in 2021, it bought middle-market broker NFP for $13B in 2024 to push down into smaller companies.
