Big Banks Go Stablecoins: Capital One Buys Brex For $5.15 Billion

Reports say Capital One will buy stablecoin fintech Brex for $5.15 billion in a deal that mixes cash and stock. According to the bank’s release, roughly half of the price will be paid in cash and the other half in Capital One stock.

Regulators must still sign off. The two companies expect the transaction to finish by mid-2026, though that timing could shift if approvals take longer.

Brex Brings Cards, Software — And Stablecoin Plans

Brex began as a corporate card and expense tool for startups and has added services for larger firms.

Reports note the company moved quickly into payment tech last year when it announced plans to offer native stablecoin payments, letting customers send and accept dollar-pegged tokens with automatic conversion back into USD balances.

That bit of tech is a major part of why the deal matters to a bank that wants faster settlement options.

A Mix Of Old And New

This is not just about software. It is also a play for customers. Brex runs business accounts, serves big names in tech, and has built a set of tools that many businesses use daily.

Some of those clients moved business deposits to Brex after the 2023 banking turmoil, and those relationships are part of the package Capital One is buying.

The price tag looks smaller than Brex’s peak private valuation years ago, which shows how venture valuations have reset across the sector.

Banks have been testing token-based rails and faster settlement for a while. By folding Brex into its operations, Capital One gains a ready platform that already experiments with stablecoin rails.

Real-time settlement for businesses can lower friction and could cut the waiting time for funds to clear. At the same time, regulators in the US and abroad are paying closer attention to token projects, so the new setup will run under tighter scrutiny.

Stablecoins have drawn growing attention across traditional finance after Congress approved major rules for the tokens last year.

Based on data from Coingecko, the total value of stablecoins has climbed over 18% to an all-time high of $315 billion since the GENIUS Act was passed in July 2025. USDT takes the lion share of the overall stablecoin market.

Reports note that Pedro Franceschi, Brex’s CEO, will continue to lead the unit after the sale, now inside Capital One.

Investors reacted calmly overall; Capital One’s shares dipped early but were supported by robust quarterly results announced at the same time. That earnings strength helped soften any sharp market moves.
