Schwab’s Record Quarter Shows Growth, but Cash Economics Still Matter

Charles Schwab posted record third-quarter results as clients added assets and traded more, but the quarter also showed why investors remain focused on the broker's cash economics.

Schwab reported net income of $2.9 billion and GAAP earnings of $1.62 a share for the third quarter of 2026. Adjusted earnings were $1.69 a share after excluding $151 million of pretax transaction-related costs. Revenue rose 17% from a year earlier to a record $7.2 billion.

Client growth was the strongest part of the report

Clients opened 1.2 million new brokerage accounts and brought in $190.4 billion of core net new assets, 38% more than a year earlier. That represented a 5.8% annualized organic growth rate. Trading revenue rose 16% to $1.2 billion as engagement stayed high.

Those figures correct a small discrepancy in the secondary report, which cited $192.4 billion of net new assets. Schwab's own release reported $190.4 billion in core net new assets and another $2.0 billion of inflows from off-platform retail certificates of deposit.

Asset gathering matters because Schwab can earn multiple revenue streams from the same relationship, including asset-management fees, trading revenue and interest on client cash and lending balances. The company also benefits when advisers consolidate more client assets on its platform.

The interest model remains the pressure point

Net interest revenue still supplies nearly half of Schwab's total revenue. The broker earns a spread by investing and lending cash held across client accounts, so its margin depends on funding costs, asset yields and how much cash clients leave in low-yield sweep balances.

The source report said third-quarter net interest margin was 3.04% and that management expected the full-year result near the lower end of its range. It also noted $5.5 billion of additional short- and long-term funding, taken as a prudent response to higher rates and unrealized securities losses. Those actions support liquidity, but more expensive funding can limit margin expansion.

AI agents have been discussed as a possible threat because automated tools could move idle cash to higher-yielding alternatives. The third-quarter numbers did not show a disruption to asset gathering or trading. That does not eliminate the risk; it shows that client growth currently outweighs it.

The investor question after this record quarter is not whether Schwab can attract assets. It is how profitably the company can monetize them as clients become more active, more tax-aware and more willing to move cash. Continued organic growth combined with stable funding costs would support the bull case. A weaker interest margin would make record asset inflows less valuable than the headline suggests.
