A Supreme Court Ruling Against Trump's Tariffs Could Trigger Up to $175 Billion in Refunds, a Potential Tailwind for Import-Heavy Retailers

The Supreme Court ruled that President Trump's tariffs imposed under the International Emergency Economic Powers Act exceeded congressional authority, potentially unlocking up to $175 billion in refunds for U.S. businesses that paid the levies. Walmart (WMT), Costco (COST), and Target (TGT) stand among the import-heavy retailers positioned to capture cash-flow windfalls and margin relief if refunds materialize.

The ruling strikes down tariffs enacted under IEEPA, though it leaves intact duties imposed under separate trade authorities. Companies that absorbed tariff costs rather than passing them fully to consumers could see the largest benefit, though the magnitude will vary based on each retailer's tariff exposure and pricing strategies during the original implementation.

Legal proceedings and administrative timelines may delay actual payments, creating uncertainty around when—or whether—the full $175 billion estimate reaches corporate balance sheets. The decision does not eliminate all Trump-era trade measures, meaning import costs remain elevated in certain categories.
