Fun facts about Chubb Ltd

Quirks, history, and lore behind CB — the kind of stuff that makes a stock memorable.

1
The Basics
A property and casualty insurance giant · large-cap · listed on the NYSE · legally domiciled in Switzerland but operationally global.
2
The Numbers
One of the largest publicly traded P&C insurers in the world, with annual net premiums written north of $40 billion and a market cap well above $100 billion.
3

The modern company was born from a 2016 merger that combined a storied U.S. insurer with a Swiss holding company — a deal that created a global insurance powerhouse almost overnight.
4
The Secret
It specializes heavily in high-net-worth individuals — insuring the mansions, art collections, and yachts of the ultra-wealthy, not just your neighbor's Honda.
5
The Lore
Warren Buffett quietly built a massive stake in this company, calling it one of the best-managed insurers in the world — high praise from a man who built Berkshire on insurance float.
6
The Giveaway
The name once belonged to a scrappy 1980s corporate raider, but today it's synonymous with blue-chip insurance — and its two-letter ticker is just as clean and simple as its underwriting standards.
