Citi commerce media: the Kard acquisition and what Citi has announced

Citi is buying the offers engine rather than building one. Kard describes itself as "the first independent commerce media network" and sells its rewards platform to fintechs, banks and neobanks (Kard, accessed 9 November 2026). Chase took the same path when it bought Figg in 2022 and launched Chase Media Solutions two years later. If Citi follows that pattern, a Citi-branded network would sit on technology already used by other issuers.

Citi also sits on the other side of the market. It was named the key scale partner of Mastercard Commerce Media in October 2025. Owning Kard would give Citi its own engine as well. Neither company has said how the two will fit together, and we draw no conclusion from the overlap.

The deal is small in Citi's terms. Citi did not disclose the price and said it is not material to its results (Citigroup, 13 August 2026). Citi's quarterly report for the period ended 30 September 2026 does not mention Kard (Citigroup 10-Q, Q3 2026).

Offers. Kard runs card-linked offers: location offers, category discounts, tiered benefits and spending challenges, shown in a partner's app under the partner's brand (Kard, accessed 9 November 2026). Partners can alert customers by push notification and email.

Citi surfaces. Citi has not said where Kard offers will appear, for example in the Citi app or online banking. We found no Citi display, offsite or in-store media product. For how offer programs work in general, see card-linked offers explained.

Kard targets new, existing or lapsed customers on first-party transaction data. Citi's release describes Kard connecting financial institutions and merchants "through verified transaction data and merchant-funded rewards".

What would stay inside, and what merchants would receive, under Citi ownership is not public. Kard states that its platform is PCI-compliant and SOC 2-certified (company claim). It says merchants pay for verified purchases, not impressions, which implies they receive redemption-level reports. Any sharing of Citi customer data with merchants would fall under the notice and opt-out rules explained in GLBA and advertising with bank data. Banks that keep such data in-house usually follow the pattern in launching a bank media network without moving customer data.

Kard says it tracks each purchase, links it to the offer and reports incrementality and ROAS (Kard, accessed 9 November 2026). These are company claims. Citi has not described how it will report results to merchants or whether lift tests will use holdout groups.

1. Today, buy through Kard or Mastercard. Until closing, Kard and Citi operate independently, so a merchant buys Kard's network or Mastercard's offers as before.
2. Ask Kard about Citi timing. Ask when Citi cardmembers may join Kard's network.
3. Check overlap. If you fund offers on several networks, check which ones already reach Citi cardholders.
4. Agree verification. Require purchase-level redemption reports and a holdout design.
5. Re-check after closing. Expect new terms once Citi decides how to package the offer.

It suits:

• merchants that already fund card-linked rewards on fintech and bank apps;
• brands that want to be early in a large issuer's program.

It suits less:

• buyers who need a live Citi product with published scale today;
• advertisers seeking display, video or offsite audiences.

• The closing date, or whether regulators must approve the deal.
• Where offers will appear in Citi's channels, and under what brand.
• Pricing, minimum spend and how revenue is shared between merchants, Kard and Citi.
• How Kard counts the cardholders in its network, and whether the count will include Citi.
• How the deal affects Citi's role in Mastercard Commerce Media.
