American Express holds a decisive edge in this valuation matchup, with its roughly $227 billion market capitalization as of late August far exceeding Stripe’s most recent $159 billion tender-offer valuation set in February 2026. Traders price in Amex’s public-market liquidity, steady earnings trajectory, and equity performance as reliable anchors through year-end, while Stripe’s private status limits repricing to infrequent secondary transactions despite its robust 34% payment-volume growth to $1.9 trillion. This $68 billion gap, absent near-term IPO or major funding catalysts for Stripe, underpins the 86% implied probability that Amex maintains the higher figure on December 31.

NPM Prices are published for trading days only and are updated once daily at 1:00 PM ET on the following calendar day.
If NPM has not published relevant data for the specified date by 1:00 PM ET on January 1, 2027, this market may remain open until 11:59 PM ET on January 4, 2027. If no further data is released by that time, the market will resolve according to the latest data available.
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 the private company completes an IPO or direct listing before the specified date, this market will resolve according to the company's public market capitalization at the market close of the specified date or the most recent trading day.
