Moat Score — Aon plc
Total Moat Score
18 / 30
| Moat Factor | Score | Analysis |
|---|---|---|
| Intangible Assets Patents, trademarks, brand strength, or regulatory licenses that protect a company's products or services from being freely copied by competitors. | 4 / 5 | Aon has a globally recognized brand in risk and insurance advisory, deep specialty expertise (cyber, catastrophe modeling, executive risk), and proprietary data and analytics platforms that are hard for smaller brokers to replicate. |
| Cost Advantage A durable ability to produce goods or services more cheaply than competitors — through scale, unique access to cheap inputs, location, or process — that lets a company undercut rivals or out-earn them at the same price. | 2 / 5 | Scale provides some efficiency in placement and back-office operations, but Aon is a premium advisory firm rather than a low-cost operator, and rivals like Marsh McLennan operate at comparable scale. |
| Pricing Power The ability to raise prices without losing meaningful business, because the product or service is differentiated, mission-critical, or has few good substitutes. | 3 / 5 | Fee-based advisory relationships and specialty expertise support decent pricing power, though commission-based revenue is also exposed to broader insurance market pricing cycles that Aon does not control. |
| Network Effect The product or service becomes more valuable to every user as more people or organizations use it, making an established leader harder to displace. | 2 / 5 | Aon's scale gives it broader carrier relationships and richer proprietary risk data that improve its advisory value as it grows, a modest data/scale flywheel rather than a true multi-sided network effect. |
| Switching Costs The money, time, or operational disruption a customer would face switching to a competitor, which locks in existing customers and supports renewals. | 3 / 5 | Corporate clients typically retain brokers for multi-year relationships given the complexity of switching risk programs and RFP processes, creating meaningful but not insurmountable stickiness. |
| Efficient Scale A market that can only profitably support a small number of players, so incumbents face limited threat from new entrants even without other defenses. | 4 / 5 | Global insurance brokerage at the large-enterprise and specialty level is effectively an oligopoly dominated by Aon, Marsh McLennan, and a few others, with scale, talent, and carrier relationships forming real barriers to new entrants. |
