American Express trades at a market capitalization of approximately $227 billion, supported by steady double-digit revenue growth, a 34%+ return on equity, and normalized P/E multiples around 20x amid consistent earnings expansion in its credit services business. In contrast, Stripe's most recent confirmed tender valuation stands at $159 billion from February 2026, with secondary-market implied levels reaching $185–200 billion, reflecting rapid payments-volume expansion and the recent $7.5–8 billion OpenRouter acquisition that deepens its AI exposure. Traders assign an 85.5% implied probability to American Express maintaining the higher valuation by year-end because Stripe would require outsized private-market appreciation or a transformative catalyst—such as a large acquisition close or IPO—to close the gap within the remaining months, while American Express benefits from established scale, transparent financial reporting, and lower volatility in its equity pricing. Key upcoming factors include Stripe's continued AI and payments momentum versus American Express's quarterly earnings trajectory and any shifts in consumer credit trends.

If NPM ceases publishing relevant data prior to the specified date, this market will resolve based on the NPM data published prior to the cessation of coverage, as well as applicable public market capitalization data following an IPO or direct listing.

If a listed company is acquired, merges into another entity and is no longer the surviving parent company, or otherwise ceases to exist as an independent entity prior to the end of the period, only the NPM valuation and applicable public market capitalization achieved prior to completion of the transaction will be considered for resolution. No transaction, acquisition, or merger consideration will be considered for resolution.
The resolution source for the private company is NPM data published here (https://fe.secondmarket.com/companies/company-6edded11-6786-4392-9695-3cce6fda0de0/data?return_url=https://test8298192.pages.dev/finance/privates).
