What the company does
Aon (UK/Ireland) is the world's second-largest insurance broker and risk adviser: it places insurance and reinsurance for companies and consults on pensions/HR. Revenue comes from commissions and consulting fees.
What was checked
The AAOIFI standard has four steps: business activity first, then three financial ratios. Fail one and the stock is not halal.

Figures from the company's filings (2026-06-30), USD. Market cap is a 36-month average (the S&P Shariah index approach), so a one-day price move does not flip the verdict. Today's market cap: $61.00B.
For information (AAOIFI 3/1 note): cash + receivables are 36.5% of total assets (2026-06-30). AAOIFI recommends tangible assets of at least one third — this figure does not affect the verdict, and other major screeners do not apply it either.
