Interchange Uncertainty, VAMP Pressure, and AI Chargebacks: June 2026 Roundup

A settlement ruling, a new acquirer monitoring program, and an AI chargeback tool all landed in the same week. For U.S. merchants, the common thread is cost and risk around card acceptance. The Visa-Mastercard interchange settlement is approved, but experts say further challenges are likely. VAMP is reshaping how acquirers manage merchant risk. A new AI product now targets the chargeback dispute process.

## Industry moves

**Visa-Mastercard Interchange Settlement Approved**

A federal judge approved the Visa-Mastercard interchange fee settlement, resolving a merchant antitrust lawsuit over swipe fees. Payments Dive covers the four reasons the court upheld the deal (https://www.paymentsdive.com/news/4-reasons-the-visa-mastercard-pact-survived/822503/). The ruling caps interchange rates and adjusts fee structures for U.S. merchants accepting Visa and Mastercard. Check whether your business qualifies under the settlement class.

**Interchange Dispute Is Not Over**

The court approval has not ended the broader argument. Digital Transactions reports that payments observers expect further legal challenges (https://www.digitaltransactions.net/the-argument-over-interchange-is-far-from-settled-observers-say/). Interchange fees apply to every card transaction. Ongoing proceedings will continue to affect what U.S. merchants pay to accept credit and debit cards.

**VAMP: Acquirer Pressure Passes Downstream**

Visa's Acquirer Monitoring Program (VAMP) tracks fraud and chargeback activity at the acquirer level. One year in, Digital Transactions reports acquirers and their vendors are adapting compliance workflows in response (https://www.digitaltransactions.net/a-year-in-vamp-is-turning-acquirer-anxiety-into-opportunity/). Merchants with elevated dispute rates can push an acquirer over VAMP thresholds. Processors under threshold risk may manage or terminate high-dispute accounts.

**AI Tool Targets Chargeback Disputes**

Findustry AI Inc. launched Chargeback Agent, an AI product targeting chargeback disputes for merchants and payment providers. Digital Transactions covered the launch (https://www.digitaltransactions.net/findustry-ai-takes-aim-at-chargebacks/). Pricing, win rates, and integration details were not disclosed. Merchants with high chargeback volumes should request those specifics before evaluating the product.

## The takeaway

Pull your dispute rate report this week. If your chargeback rate is elevated, you may be pushing your acquirer over VAMP thresholds, increasing the risk of account termination. Also confirm with your bank or attorney whether your business qualifies under the Visa-Mastercard interchange settlement class.
