Non-Bank ATM Surcharge Settlement

Visa and Mastercard allegedly violated antitrust laws by creating operating rules that prohibited independent ATM operators from charging different surcharges based on the network used to process transactions. This prevented cardholders from getting lower fees when using less-expensive networks, causing them to pay higher ATM surcharges than necessary. Visa and Mastercard deny the claims.

Settlement fund: $167.5M
Claim deadline: February 10, 2027
Represents: MASTERCARD INCORPORATED, MASTERCARD INTERNATIONAL INCORPORATED

“Recovery” and “exposure” refer to total disclosed settlement funds in associated cases, not money personally won or lost by an attorney. Settlements generally resolve disputed allegations without a finding that either side won. Data comes from public court dockets and may be incomplete.
