What does it do?
Chubb is one of the world's largest insurance companies. Think of them as the safety net for big, complex risks — if a multinational corporation needs coverage against lawsuits, natural disasters, or cyberattacks, Chubb is often the company writing that policy. They also insure wealthy individuals' homes, art collections, and cars, plus they sell life insurance globally. They operate in over 50 countries, so when something big goes wrong anywhere in the world, Chubb is often involved.
Chubb matters right now because the insurance industry is in a rare sweet spot — after years of catastrophic losses from wildfires, floods, and storms, insurers have dramatically raised their prices, meaning companies like Chubb are collecting much more in premiums while still being selective about what they cover. With a market cap of $127 billion, Chubb is a bellwether — when it does well, it signals that the broader commercial insurance market is healthy. Warren Buffett's Berkshire Hathaway also took a notable stake in Chubb in 2023, which put a massive spotlight on the stock.
How does it make money?
Chubb makes money primarily by collecting insurance premiums — the regular payments customers make to stay covered — and then paying out less in claims than it collects. In its latest year, it brought in $47.6 billion in revenue, up from $45.1 billion the prior year, a 5.5% increase. It also earns significant investment income by taking the premiums it holds and investing them in bonds and other assets while waiting to pay claims. Net income came in at $10.3 billion, which is an exceptionally strong profit margin for an insurer, reflecting both disciplined underwriting (choosing which risks to take on) and a favorable pricing environment.
Why do investors care?
Investors like Chubb because it sits in a part of insurance — high-end commercial and specialty coverage — where it has real pricing power and faces less commoditization than basic auto or home insurance. The growth story is twofold: expanding into emerging markets through its Overseas General Insurance segment, and capturing more business as companies face growing risks from climate events and cyber threats. For the thesis to work, Chubb needs to keep claims costs under control (no catastrophic disaster year wipes out profits), maintain strong investment returns as interest rates stay elevated, and continue growing premiums faster than inflation.
