Capital One Starts Migrating Core Cards to Discover Network

Capital One is beginning to unveil its playbook for the Discover integration, with some of its core credit cards now being issued on the acquired network.

Updated benefits guides, first reported by The Street, show that new customers will receive Capital One-branded cards such as Savor, Quicksilver, and VentureOne on the Discover rails. Existing cardholders likely won’t see changes until their current cards expire, when they are expected to be migrated over.

Slow-Rolling the Integration

For now, the premium and business portfolios appear unaffected, including the flagship Venture X.

“Capital One is hedging its integration by keeping Venture X on the Visa network for now,” said Brian Riley, Director of Credit at Javelin Strategy & Research. “When coupled with the brands selected to be on the four party networks, this recognizes the dominance of Mastercard and Visa networks in payment acceptance. While it does not suggest a long-term plan to remain on those networks, it suggests a thoughtful plan to execute towards the Discover network cautiously.

“Capital One’s business cards, including Spark and Venture X Business, remain on the Mastercard network,” he said. “Discover does not support a large business-card audience, and Capital One recently announced its intention to acquire Brex, a fintech with a substantial commercial card portfolio.”

The issuer is also keeping cobranded partnerships off the Discover network for the time being. That includes cards tied to T-Mobile, Kohl’s, Bass Pro Shops/Cabela’s, among others.

Shuffling the Cards

The merger of Capital One and Discover, completed in May 2025, has been rolling out in phases. The first step came through the debit portfolio, which has roughly 25 million cards in circulation.

Historically, Discover’s card business was centered on a single flagship product, the iT card. By contrast, Capital One is folding multiple rewards franchises into the network—including products with annual fees, a departure from Discover’s traditional structure—along with their no-fee counterparts. Fully consolidating the combined lineup is expected to take years.

“In the long term, it is unlikely that Capital One will operate in two network ecosystems,” said Riley. “We expect it to take five years for the full shift to take place. Converting based on expiration dates is a solid, cautious strategy.”
