American Express (AXP) Stock Forecast & Price Target

American Express is increasingly demonstrating that its heavy reinvestment is translating into a stronger, more durable growth engine rather than a cost burden, with revenue per dollar of investment spending and OpEx stabilizing at $1.63 in LTM2Q26 and holding broadly steady through 2Q26. The company’s rebuilt product flywheel is driving deeper monetization, as net card fees grew at an ~16% CAGR from 2Q18 to 2Q26 while proprietary cards-in-force rose only ~3%, average fee per proprietary card increased ~12%, and Millennials and Gen Z lifted their share of U.S. Consumer Services billed business to ~38% in 2Q26. At the same time, its reserve rate remains materially below selected issuers, supporting the view that growth is being achieved with favorable credit economics and a durable EPS compounding profile.

American Express is facing a more fragile demand backdrop as even super-prime consumers may struggle to sustain spending, while its growing exposure to Millennials and Gen-Z could leave fee income more vulnerable to macroeconomic pressure. Commercial spending has decelerated more sharply, and although new account growth in both Consumer and Commercial has offset some same-customer slowdown, the thesis is that this mix will not prevent near-term weakness in billed business momentum. The valuation work points to 16x 2026 EPS and 15x 2027 EPS versus a historical 15x 1yr forward P/E, but the negative view is driven more by slowing spend trends than by expected credit loss deterioration.
