Capital One has announced an agreement to acquire fintech startup Brex for $5.15 billion, with the deal structured as a 50% cash and 50% stock transaction. Brex, founded in 2017, is known for providing corporate credit cards and cash management tools, primarily targeting startups and large enterprises. The acquisition will enable Capital One to expand its presence in emerging payment technologies, particularly with Brex's recent plans to introduce a stablecoin payment feature. Brex's stablecoin initiative, announced in September 2025, aims to make it the first global corporate card platform to support instant balance payments using stablecoins. This strategic acquisition will integrate Brex into Capital One's commercial banking and payment services, enhancing its offerings in the fintech space. Notably, several blockchain companies, including Figure, Solana, and Alchemy, have already expressed interest in Brex's stablecoin products.
