Airwallex raises $320m at an $11bn valuation, betting on agentic finance

A 38% jump in valuation over six months is the kind of figure that tells you where investor appetite has gone. Airwallex, the global payments company, has raised $320m in a Series H round that values it at $11bn, up from $8bn in December 2025.

The raise is being directed squarely at the part of the market that now attracts the most capital: financial software run by AI agents.

The round was led by returning investor Addition, with a long supporting cast that included Baillie Gifford, Hummingbird, QED Investors, T. Rowe Price, Hedosophia, Haun Ventures, Amex Ventures, and Washington University in St. Louis.

The mix of crossover funds and a university endowment is the sort of investor list a company assembles when it is positioning for a public market rather than another private round.

The underlying numbers explain the enthusiasm. As of March 2026, Airwallex reported $1.3bn in annualised revenue, up 74% year over year, and $287bn in annualised transaction volume, up more than 120%.

Those are growth rates that justify a premium, and the company is spending the new money to defend them, with plans to expand its infrastructure and regulatory footprint into new markets and to keep building its engineering teams.

The strategic pitch is agentic commerce, the idea that AI agents will increasingly transact on behalf of users and businesses, and that the payments rails underneath need to be built for software rather than people.

It is a thesis the sector is converging on quickly, with firms such as Meow Technologies launching banking built for AI agents.

Airwallex paired the raise with two new products aimed at the same idea: T:0, an autonomous finance platform, and Airi, which it describes as an agentic consumer wallet.

The valuation history reads like a chart pointed in one direction. Airwallex raised $330m in a Series G at an $8bn valuation in December 2025, and the new round lifts that figure to $11bn barely six months later.

Founded in Melbourne and now operating with a dual headquarters that includes San Francisco, the company has positioned itself as a cross-border payments and financial-infrastructure provider for businesses, the kind of plumbing that becomes more valuable as commerce moves online and across borders.

It sits among a cohort of fintech firms rebuilding money movement from the rails up.

The roster of returning and new backers signals where the money expects the company to go next. Crossover investors such as T. Rowe Price and Baillie Gifford typically take positions in late-stage private companies they expect to follow into the public markets, and the addition of Amex Ventures hints at the payments incumbents’ interest in what Airwallex is building.

The enthusiasm is selective: AI has crushed the valuations of pre-ChatGPT companies even as it lifts firms that can credibly attach themselves to the agentic story.

None of this guarantees a listing, and the company has not signalled a timeline, but the shape of the cap table is the shape of a company being readied to be looked at by public investors.

Whether autonomous agents move money at the scale the marketing implies is still unproven, and the phrase “agentic finance” is doing a lot of work across the sector right now.

What is concrete is the capital, the valuation, and a revenue line growing fast enough to keep both rising. The next milestone to watch is whether that investor list points, as it appears to, toward an eventual listing.
