The Charles Schwab Corporation

The Charles Schwab Corporation is an American financial services firm that provides brokerage, wealth management, and retail banking services to individual investors and independent registered investment advisers, generating $23.9 billion in total net revenues in fiscal 2025. With $11.9 trillion in client assets across 38.5 million active brokerage accounts, Schwab is the largest publicly traded brokerage in the United States by both measures, and one of a handful of firms whose earnings are structurally levered to the direction of American household wealth.

This is not a simple story about a business that grows when markets rise and shrinks when they fall. The Charles Schwab Corporation is an asset-gathering machine that has compounded its client base for five decades through a distinctive formula: it competes on price in the commodity layers of the stack — commissions, fund expenses, deposit rates — while monetizing the assets those low prices attract through net interest spread, advisory fees, and an expanding suite of lending and wealth offerings. The integration of TD Ameritrade, completed at the end of 2024, added roughly $1.9 trillion in client assets and made Schwab the unrivalled scale player in its market.

The file turns on two questions. The first is whether the net interest margin recovery that drove earnings from $5.07 billion in 2023 to $8.85 billion in 2025 has further to run, or whether the cycle has largely played out. The second is whether artificial intelligence — which Schwab's management frames as an accelerant — represents a structural threat to the sweep-cash economics that have historically supplied roughly half the firm's revenue. Both questions speak to the durability of Schwab's business model in a world where software can do to deposit spreads what zero-commission trading did to transaction fees.
