How AIG Makes Money

AIG operates a disciplined, high-capacity global commercial property and casualty business model organized into two primary divisions within General Insurance: (1) Commercial Insurance (~75% of premiums), which underwrites commercial property, general liability, financial lines (D&O/E&O), cyber risk, marine, aerospace, and energy infrastructure across North America and International markets; and (2) Personal Insurance (~25%), which underwrites high-net-worth personal property (Private Client Group partnership), travel insurance, and personal accident/health. AIG commands an extraordinary market position through its wholly owned subsidiary Lexington Insurance Company—the largest surplus lines underwriter in the United States—which underwrites high-risk, complex commercial exposures that standard admitted carriers decline. AIG monetizes its platform through gross written premiums, net earned premiums, reinsurance quota-share commissions, and investment returns across its $90+ billion general investment portfolio.

AIG is executing a focused three-pillar growth strategy: (1) Capitalizing on surging market demand in excess & surplus (E&S) commercial lines through Lexington Insurance, capturing high-margin middle-market commercial property risks flowing out of admitted carrier markets; (2) Expanding multinational commercial programs for international enterprise clients navigating geopolitical supply-chain re-shoring and clean energy infrastructure projects; and (3) Deploying enterprise machine-learning underwriting models (AIG Next) to automate intake, contract wording analysis, and digital policy issuance.
