Capital One is closing in on its goal to dominate the US payments landscape, snapping up Brex in its second acquisition in rapid succession.
Capital One has agreed to acquire fintech Brex for $5.15bn, strengthening the bank’s push into business payments.
The agreement, announced on January 22, will see Capital One acquire the corporate spend management platform at less than half of Brex’s $12.3bn valuation from 2021.
There are several reasons Capital One is getting what looks like a bargain for Brex, including the company’s 2022 decision to pivot toward larger enterprises and abandon many of its small and mid‑sized customers, as well as its strategy to prioritise growth over profit.
Founded in 2017, Brex initially targeted startups with corporate cards designed for venture-backed companies unable to access traditional credit. It later expanded into expense management, banking and real-time payments.
According to the company, Brex now serves tens of thousands of customers, including one in three US startups and hundreds of public companies.
Capital One founder and CEO Richard Fairbank described the acquisition as a natural extension of the bank’s technology-led strategy. He said the deal accelerates Capital One’s ambition to become a “payments company at the frontier of the technology revolution,” particularly in the business payments market.
Fairbank highlighted Brex’s full-stack model as a key reason for pursuing the deal, noting it had built an integrated platform spanning cards, banking and spend software “from the bottom of the tech stack to the top.”
Brex CEO and Co-founder Pedro Franceschi said the company was created as a category-defining platform combining financial services and software into a single AI-native system.
He explained the Capital One agreement would “supercharge” Brex’s next chapter by pairing its payments and spend management capabilities with Capital One’s size and brand reach.
Under the agreement, Franceschi will continue to lead Brex, which will operate as part of Capital One following regulatory approval, expected by mid-2026.

A big step in an even greater strategy
The Brex acquisition is more proof of Capital One’s expansion across payments and card networks, following its $35.3bn acquisition of Discover Financial Services in May 2025.
Its purchase of Discover created the largest credit card issuer in the US by loan volume and gave Capital One control of the Discover, PULSE and Diners Club International payment networks, enabling the bank to compete more directly with Visa and Mastercard.
The Discover and Brex deals remodel Capital One from a major card issuer into a full-stack payments and financial infrastructure provider, bridging consumer credit, merchant acceptance, business banking and spend software.
While Discover bolstered Capital One’s network and issuing scale, Brex adds modern corporate payments technology, automation and AI-driven expense management, which are capabilities traditional banks have historically struggled to build internally.
“This isn’t a story about cost synergies. It’s a story about growth acceleration, about two founder-led companies coming together to bring a better way to manage money to millions of businesses in the mainstream US economy, who are dramatically underserved by traditional banks,” said Franceschi.
“To give you a sense of the scale of what we’ll build together, Capital One today operates orders of magnitude ahead of Brex on almost any metric: $900bn in annual card GMV, $700bn in assets, $150bn in market cap, a $6bn marketing budget, and a $6bn R&D budget.”
