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%.
