The group traces its roots to 1792, when investors met at Independence Hall in Philadelphia to organise the Insurance Company of North America (INA). In 1882 Thomas Caldecot Chubb and his son Percy opened a marine underwriting business in New York as Chubb & Son. ACE Limited was formed separately in 1985, backed by 34 founding sponsors, to address a shortage of excess liability and directors and officers cover. ACE listed on the NYSE in 1993, bought the reinsurer Tempest Re in 1996 and acquired CIGNA's P&C business for $3.45 billion in 1999, which took it into 50 countries. Evan Greenberg, who joined ACE in 2001, became CEO in 2004. In January 2016 ACE acquired The Chubb Corporation for about $28.3 billion and the combined company adopted the Chubb name.
Chubb reported record results for 2025: net income of $10.31 billion, up 11.2%, and core operating income of $9.95 billion, up 8.9%. Consolidated net premiums written reached $54.8 billion, up 6.6%, made up of $47.56 billion in P&C (up 5.4%) and $7.28 billion in life insurance (up 15.1%), and the P&C combined ratio was a record 85.7%. Book value per share ended the year at $188.59, up 18.0%. Total revenue was about US$55.75 billion for fiscal 2024 and roughly US$59.6 billion for fiscal 2025, and the company carries a market capitalisation near US$137.6 billion. In the third quarter of 2026 it posted record core operating income of $7.66 per share on net premiums written of $15.1 billion.
Chubb employs approximately 45,000 people across its 54 countries and territories. It is led by Evan G. Greenberg as Chairman and Chief Executive Officer, John Keogh as President and Chief Operating Officer and Peter Enns as Chief Financial Officer.
