Global financial infrastructure platform Airwallex has raised $320 million in a Series H round, pushing its valuation to $11 billion — up sharply from $8 billion just six months ago. The round was led by existing investor Addition, with participation from Baillie Gifford, T. Rowe Price, Amex Ventures, and others. The funding signals a strategic push to build an AI-native financial operating system for a new generation of startups that operate globally from day one.
The gap between AI speed and financial plumbing
AI agents are moving from advisors to executors, autonomously purchasing cloud computing, subscribing to SaaS, and paying overseas suppliers. But the financial systems they rely on still run on manual approvals and T+2 settlement cycles. For B2B AI companies with cross-border needs, this mismatch is acute: a fast-growing Chinese AI firm may need to pay cloud providers in the US, Europe, and Southeast Asia in multiple currencies, navigating different compliance regimes, exchange rate volatility, and unpredictable settlement delays.
Forrester reports that AI-agent-assisted payments moved from proof-of-concept to real deployment between 2024 and 2025. OpenAI enabled agent-assisted payments in ChatGPT in September 2025, and Stripe launched its Agentic Commerce Protocol. Yet the underlying financial infrastructure remains fragmented. One CFO serving multiple AI startups described spending nearly a week each month just reconciling accounts across a dozen countries, while management operated with days-old data — a dangerous lag when currencies swing or regulators audit.
Airwallex's two-pronged strategy: T:0 and Airi
Founded in 2015, Airwallex has spent a decade building a global compliance network with over 85 regulatory licenses and 160 local payment networks. It now processes $287 billion in annualized transaction volume, with 93% of transactions settling same-day across 200+ countries. The Series H funding will accelerate two new products designed to layer AI intelligence on top of this infrastructure.
T:0 is an autonomous finance department that integrates bookkeeping, forecasting, tax, compliance, reporting, and reconciliation into a single continuous platform. It eliminates the friction of fragmented tools by running on Airwallex's existing payment rails and multi-currency accounts, giving startups a CFO-grade ledger with built-in compliance from day one. Currently in private beta, T:0 is expected to roll out more broadly within weeks.
Airi addresses agentic commerce — the reality that AI agents will soon make purchases on behalf of humans. Unlike existing solutions from OpenAI/Stripe and Mastercard that layer AI on top of traditional card networks, Airi builds a native agent wallet from the ground up. AI agents can hold dedicated cards, initiate transactions within set limits, and call on multi-currency balances under a regulated framework. Early tests show a 14% boost in merchant conversion rates with one-click checkout. Airi will evolve into a full agent wallet infrastructure, completing the money flow from discovery to settlement.
Why now, and why Airwallex
The funding round comes as Airwallex has already turned profitable: annualized revenue reached $1.3 billion, ARR turned positive in Q4 2025, and over 675,000 businesses use its platform. The company's moat lies in its decade-long accumulation of licenses and local network connections — assets that cannot be quickly replicated with capital. Amex Ventures' participation underscores the value of this compliance infrastructure.
In an era where AI agents operate across ecosystems from OpenAI to Anthropic to Google, being protocol-agnostic is a strategic advantage. Airwallex combines a hard-won global compliance backbone with a first-principles product architecture built for the agentic economy. As Gartner predicts that 33% of enterprise software will integrate agentic AI by 2026, the window for companies still relying on traditional bank accounts and manual approvals is closing fast. Startups that want to go global from day zero need a financial operating system that is global from day one.
