United States bank Capital One has agreed to acquire technology and stablecoin firm Brex in a deal valued at $5.15 billion. The transaction will be paid in roughly 50 percent cash and 50 percent stock, according to the company’s statements.
The purchase brings one of Silicon Valley’s best-known corporate spend platforms inside a major American bank. Capital One says Brex will strengthen its commercial payments business after last year’s Discover acquisition.
What Brex Brings To Capital One
Brex was established in 2017 and provides startups and big businesses with corporate cards, spending management solutions, and AI-powered software. Through money market funds and partner banks, the organization also oversees around $13 billion in customer deposits.
In September 2025, Brex announced native stablecoin payments starting with USDC, built with bank partner Column and a stablecoin infrastructure firm. Clients can send and receive USDC, and balances are automatically converted to U.S. dollars in Brex accounts.
Brex’s stablecoin system lets companies make large cross-border payments at any time with near-instant settlement. Leading crypto and blockchain firms, including Solana, Figure, and Alchemy, have already signed up to use the platform.
By buying Brex, Capital One gains in-house stablecoin and digital payment infrastructure instead of building them from scratch. The move positions the bank to serve both traditional enterprises and crypto-native businesses through a single platform.
Deal Timeline, Valuation, And Market Context
The acquisition is expected to close later this year, subject to regulatory and shareholder approvals. It will be Capital One’s largest technology-focused deal since its 35 billion dollar purchase of Discover.
Brex was last valued at 12.3 billion dollars in private funding rounds, so the 5.15 billion price marks a sharp discount for late investors. The sale also highlights a new phase in which mature fintech and stablecoin players are joining big banks rather than remaining independent challengers.
