Citi Launches Commerce Media Platform to Monetize Transaction Data…

Event summary

Citi's U.S. Consumer Cards business launched Citi Commerce Media on September 23, 2026, a media platform leveraging transaction data to help brands target customers.
The platform analyzes 6.5 billion annual transactions across 700 spending categories for 70 million U.S. customers.
Citi Commerce Media combines consumer insights, paid media solutions, and closed-loop measurement to improve ad targeting.
Initial campaigns showed up to 5x incremental return on ad spend for an online retailer.
The launch follows Citi's agreement to acquire Kard, a commerce media and rewards platform.

The big picture

Citi's move into commerce media reflects the broader financial services trend of leveraging proprietary data to create new revenue streams. With 70 million U.S. customers and billions of transactions, Citi is positioning itself as a key player in the evolving advertising landscape, where first-party data is increasingly valuable. The acquisition of Kard suggests a strategic push to integrate rewards and media capabilities, potentially creating a more sticky ecosystem for both customers and brands.
