According to Polymarket, there is a 19% chance courts will order a tariff refund by July 2026, after the U.S. Supreme Court ruled 6–3 that Trump’s tariffs violated IEEPA, affirming lower court decisions.
Polymarket data indicates a 19% probability that courts will order Donald Trump to refund tariffs by July 2026, and an 82% probability of a negative ruling. On Feb. 20, the U.S. Supreme Court ruled 6–3 that Trump’s trade tariffs were illegal under the International Emergency Economic Powers Act (IEEPA), affirming lower court decisions. This market assessment contrasts with earlier Kalshi pricing that suggested a 66% likelihood of a refund order.
