Brex to Power OpenAI's Global Finances Amid Rapid Scale

By Sharon Kelly

SAN FRANCISCO, CA – March 18, 2026 – In a move that underscores the symbiotic relationship between artificial intelligence and the financial technology that supports it, Brex announced today that it is powering the global spend and financial operations for AI pioneer OpenAI.

The partnership places Brex's intelligent finance platform at the heart of one of the world's fastest-growing and most influential technology companies. As OpenAI continues its meteoric expansion, the deal validates the increasing need for sophisticated, AI-native financial tools to manage the complex demands of hyper-growth on a global scale.

The Financial Backbone for Hyper-Growth

OpenAI's trajectory is one of unprecedented speed and scale. With its products reaching hundreds of millions of users and a rapidly growing roster of enterprise clients, the company faces immense operational challenges. Managing a globally distributed workforce and dynamic, high-volume spending requires a financial infrastructure that is both agile and rigorously controlled.

This is the core problem Brex aims to solve. The platform provides OpenAI with a unified system for corporate cards, global payments, and spend management across more than 200 markets. For a company like OpenAI, whose financial activities are as complex as its AI models, the ability to gain real-time visibility into spending patterns, automate policy enforcement, and streamline expense reporting is not a luxury—it's a necessity for sustained growth. The partnership allows OpenAI's finance team to move away from manual, reactive tasks and focus on strategic financial planning.

"OpenAI is operating at a scale and speed that few companies in the world ever reach," said Pedro Franceschi, CEO of Brex, in a statement. "I'm excited for Brex's agentic technology to support OpenAI as we continue to help companies ensure speed and control in finance move in parallel."

This need for speed and control is particularly acute in the AI sector. Brex's own data from late 2025 showed an 80% year-over-year increase in spending on OpenAI services among its customer base, highlighting the massive capital flow into AI infrastructure and services. By managing the finances of the company at the center of this boom, Brex is cementing its position as a key enabler of the entire AI ecosystem.

Automation in an AI-First World

Brex's selection by OpenAI is not merely about providing corporate cards; it's about deploying a shared philosophy of leveraging AI to solve complex problems. Brex has heavily invested in what it calls "AI-native" finance, moving beyond simple automation to create a more intelligent, proactive system.

The company reports that nearly 70% of all expenses on its platform are now handled entirely by automation. This has a tangible impact, enabling managers to review expense reports six times faster and allowing accounting teams to close their books three times faster. Brex claims these efficiencies saved its customers over 208,000 hours of manual work each month in 2025.

Central to this vision is Brex's recently announced agent platform, which promises to automate entire financial workflows from end to end. This "agentic technology" aims to handle complex tasks involving expenses, compliance, and accounting with minimal human intervention. For OpenAI, this means its teams can spend less time on administrative overhead and more time on research and development.

Furthering this integration, Brex has launched an application within ChatGPT itself. This allows employees to conversationally query their own expense data—asking about recent transactions, receipt status, or spending limits—directly within the chat interface where they may already be working. The integration is governed by existing Brex permissions, ensuring data security while fulfilling the company's vision of "the best UI is no UI at all."

A Crowded Field for AI-Powered Finance

Brex's high-profile partnership with OpenAI comes amid fierce competition in the corporate spend management space. The sector is led by a new generation of fintech companies that have built their brands on the promise of using AI to disrupt traditional finance. Its most direct competitor, Ramp, has also seen explosive growth by championing AI-driven cost savings and efficiency, with some reports suggesting it has surpassed Brex in revenue.

Both companies have skillfully crafted narratives around artificial intelligence to attract venture capital and high-growth clients. In this competitive landscape, securing a flagship client like OpenAI is a significant strategic victory for Brex. The partnership serves as a powerful endorsement of its technology and its ability to meet the demands of the most innovative companies in the world.

Brex's key differentiators appear to be its global capabilities and its deep, forward-looking integration of AI. While competitors also offer automation, Brex's focus on an "agentic" platform and its early adoption of conversational interfaces like the ChatGPT app signal a unique strategic direction. For a company with the global footprint and AI-centric culture of OpenAI, these features were likely decisive factors in the selection process.

From Cards to Conversational Control

The collaboration represents the culmination of Brex's evolution from a startup-focused corporate card provider to a comprehensive intelligent finance platform for enterprises. It highlights a broader industry trend where financial tools are no longer siloed applications but are becoming deeply embedded, automated, and conversational components of a company's core operating system.

By handling the financial operations for the company that is, in many ways, defining the future of AI, Brex is not just providing a service; it is demonstrating a new paradigm for corporate finance. In this model, finance becomes less of a bureaucratic bottleneck and more of a strategic, data-driven engine for growth. The success of this partnership could set a new standard for how rapidly scaling technology companies manage their money, transforming financial operations from a series of manual tasks into an intelligent, autonomous system.
