Few rivalries in fintech carry the personal weight of the one now developing between Stripe and Airwallex. Back in 2019, Stripe offered to buy the Melbourne-based startup for $1.2 billion, when Airwallex had just $2 million in annualized revenue. Airwallex co-founder and CEO Jack Zhang spent weeks wrestling with the decision, at one point agreed to the deal, then flew home to Australia and changed his mind. That choice set the two companies on a collision course that is now playing out across multiple fronts simultaneously.
The numbers make clear how much ground Airwallex has covered since. The company now generates around $1.3 billion in annualized revenue, growing at 85 percent year over year, holds close to 90 regulatory licenses across roughly 50 markets, and processes $100 billion in annual payment volume. It serves more than 46,000 businesses in the United States alone. Stripe, by contrast, was valued at $159 billion in a February 2026 tender offer after processing $1.9 trillion in total payment volume in 2025, making it roughly 20 times Airwallex's valuation. Zhang pushes back on that framing, pointing out that Stripe's payment volume is only about six times Airwallex's, not 20, suggesting the valuation gap reflects market perception more than operational reality.
The competitive strategy Airwallex is pursuing is built around one specific vulnerability in Stripe's model: the cost and complexity of cross-border operations. Where Stripe typically charges merchants 2 to 3 percent to convert funds back into US dollars, Airwallex allows businesses to hold balances in local currencies, pay local vendors, run payroll, and cover marketing costs at interbank rates without the conversion penalty. For multinationals managing operations across multiple countries, that difference is considerable. Airwallex recently pushed further into Stripe's territory by launching a point-of-sale product that allows businesses to accept in-person payments across multiple countries through a single platform, without needing to onboard a separate local vendor in every market.
