General Motors expects to receive $500 million in refunds after the Supreme Court ruled in February 2026 that Trump's tariffs imposed under the International Emergency Economic Powers Act were illegal. GM boosted its full-year profit forecast by that amount and is one of over 330,000 importers claiming refunds from the $166 billion in invalidated tariffs. The Tax Foundation estimates these tariffs cost the average American household $700 annually, so the ruling will likely reduce some consumer costs across the board as companies recoup money and potentially adjust pricing.
