Mastercard faces significant regulatory and political headwinds, including President Trump's endorsement of the Credit Card Competition Act, which aims to increase network competition and could impact interchange fees. The company also lost a UK legal challenge over cross-border fee caps. Despite these pressures, analysts suggest Trump's proposals may have limited long-term impact. Mastercard is scheduled to release Q4 2025 earnings soon, with some optimism about its earnings surprise history and a strategy to turn incentive spend into recurring growth.
