American International Group (AIG) insures businesses against property, liability and other risks, and offers accident, health and personal insurance to individuals. Commercial insurance in North America and international markets accounts for most of its premiums. Customers pay for coverage through brokers, agents and other distributors; AIG depends on a concentrated group of key distributors that can also sell competing insurers’ products.
AIG takes on the obligation to pay covered claims in exchange for premiums. Its profitability depends on setting prices that cover claims and expenses, estimating funds needed for unpaid claims, and managing costs. Its investment portfolio supplies another main source of income, so investment performance also matters.
Insurance rules govern what AIG can sell and how it handles claims, while capital and solvency requirements constrain its insurance subsidiaries. The parent company relies on dividends and other payments from those subsidiaries to meet its own obligations, but regulation and the subsidiaries’ capital needs can limit those transfers.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
Chubb competes with AIG for business and individual customers worldwide across commercial, specialty, personal, and accident-and-health insurance. Watch Chubb’s pricing and risk selection in these overlapping lines: it prioritizes profitable coverage over winning more premiums.
Travelers competes with AIG for businesses buying property, casualty, and specialty insurance, particularly in North America. Its ability to raise business-insurance rates is worth watching, since competition and state approvals affect when it can charge more.
Arch Capital competes with AIG for customers buying international specialty insurance through U.S., European, and Lloyd’s operations. Its specialty insurance business across these platforms is the relevant comparison for AIG, rather than its mortgage insurance business.
W.R. Berkley competes with AIG for businesses buying specialized property and casualty coverage. Watch its insurance businesses serving particular industries, products, and local markets, where its decentralized teams can respond directly to customer needs.
Hartford and AIG both collect substantial premiums from businesses buying commercial property and casualty insurance. Hartford’s Business Insurance earned premiums of $13.883 billion in 2025 make that business the line to watch when comparing the two.
Axis Capital Holders Limited competes with AIG for commercial specialty and professional-liability insurance customers internationally. Watch its coverage for financial institutions and professional service providers, including protection against directors’ liability and professional mistakes.
CNA Financial Corporation competes with AIG for small, medium, and large businesses buying commercial property and casualty insurance through brokers. Its relationships with retail and wholesale brokers are worth watching because both insurers use brokers to reach business customers.
Corebridge Financial’s dividends and share-price changes feed into AIG’s net investment income because AIG still holds a significant stake in its former life and retirement business. Watch both the dividend and share value: a falling share price can reduce AIG’s investment income even though Corebridge is no longer consolidated.
AIG bought the right to offer new policies when customers in Everest Group’s global retail commercial insurance portfolios renew, paying $301 million for those renewal rights. Both run international insurance businesses, but this transferred business is the concrete link to watch for AIG.
Markel Group competes with AIG to insure businesses’ complex commercial risks. Watch Markel Insurance’s specialty underwriting profit rather than the group’s equity-investment swings; its competition centers on expertise, coverage, and service, not just price.
American Financial Group competes with AIG through its Great American businesses, which sell specialized commercial property and casualty insurance to businesses. Watch their niche-market pricing and tailored products, areas where individual operating teams have autonomy.
Kinsale Capital Group, Inc. directly competes with AIG in covering unusual or hard-to-place U.S. property and casualty risks—the excess and surplus market. Its small- and medium-sized accounts are the customer group to watch, with commercial coverage accounting for 97.0% of its 2025 gross written premiums.
RLI Corp. competes with AIG in specialty property and casualty insurance, including coverage for risks that are hard to place in the standard market, known as excess and surplus lines. Watch its individually tailored coverage and risk selection, since managing these distinctive risks is central to RLI’s returns.
Berkshire Hathaway’s primary insurance subsidiaries compete with AIG for commercial specialty coverage and risks placed outside the standard insurance market, known as excess and surplus insurance. Watch Berkshire Hathaway Primary Group rather than the whole conglomerate, whose results also include large rail, energy, manufacturing, and other businesses.
Kinsale Capital Group, Inc. earningsKNSL
Kinsale Capital Group’s report will show demand from small and midsize businesses for hard-to-place commercial cover, a market that overlaps with AIG’s specialty property and casualty business.
Read commercial premium growth alongside underwriting results. Growth with sound underwriting would suggest small and midsize businesses still want this cover and insurers can price its risks, supporting demand and pricing for AIG’s related specialty business. Weak premiums or deteriorating underwriting would point to pressure on demand or risk pricing, limiting AIG’s room to grow and earn profit in these risks.
Everest Group, Ltd. earningsEG
Everest Group’s report will show how customers in its global retail commercial insurance portfolios are renewing; AIG bought the right to offer those customers new policies at renewal.
Watch renewals in these commercial insurance portfolios alongside any premiums AIG takes on from them. Steady renewals with more premiums flowing to AIG would show the acquired renewal rights are bringing policies and income into its business. Fewer renewals or little transferred premium would mean this customer book is contributing less to AIG.
Corebridge Financial, Inc. earningsCRBG
Corebridge Financial’s report will show the dividends it pays AIG and changes in the value of AIG’s stake, both of which feed into AIG’s investment income.
Separate the dividend Corebridge pays AIG from changes in the value of AIG’s stake. A continuing dividend means cash income from the investment; a falling share value can reduce investment income AIG recognizes at fair value even if the dividend holds. If both hold up, this stake supports AIG’s investment income; if the share value or dividend falls, its contribution weakens.
American International Group, Inc. earningsThis company
AIG earns from premiums and investment income, and this report will show whether premiums still exceed insurance claims and operating costs enough to leave underwriting profit.
Read underwriting income alongside the combined ratio, the share of earned premiums used for claims and insurance expenses; below 100% means underwriting made a profit. Rising underwriting income with the ratio below 100% would show premiums are covering claims and expenses and leaving more over. Falling income, or a ratio above 100%, would show claims and expenses are eating into premiums and AIG’s underwriting is weakening.
