Trade: Supreme Court rules in favor of Trump's tariffs?
Resolution criteria on PolyGram: This market will resolve to "Yes" if the Supreme Court of the United States issues a decision that reverses, vacates, or otherwise overturns the U.S. Court of Appeals for the Federal Circuit’s August 29, 2025 decision in V.O.S. Selections, Inc. v. Trump, in which the Federal Circuit held that the tariffs imposed by Executive Orders 14193, 14194, 14195, 14257, and 14266 exceeded the President’s authority under the International Emergency Economic Powers Act (IEEPA) by December 2026, 11:59 PM ET.

| Supreme Court rules in favor of Trump's tariffs? | 0% YES | 100% NO |
Market context
In August 2025, the U.S. Court of Appeals for the Federal Circuit ruled that tariffs imposed under five executive orders exceeded presidential authority under the International Emergency Economic Powers Act. The Supreme Court's potential review of this decision will determine whether the Federal Circuit's constraints on executive tariff-setting power stand or whether the administration's legal theory prevails. The market settles affirmatively only if the Supreme Court reverses, vacates, or otherwise overturns the Federal Circuit's decision by end of 2026.
The 0% implied probability on Polymarket's order book reflects substantial scepticism about Supreme Court reversal. Historical precedent suggests courts have been cautious about expansive readings of IEEPA authority, though the Supreme Court has occasionally deferred to executive claims in national security contexts. The Court's composition and recent administrative law decisions offer mixed signals: some justices favour broad executive power in foreign commerce, whilst others have shown willingness to constrain statutory overreach. The Federal Circuit's reasoning directly addressed statutory text and prior case law, creating a higher bar for reversal than a close appellate call.
Key catalysts include whether the Supreme Court grants certiorari—no petition filing date has been publicly announced as of early 2025. If cert is granted, oral arguments typically occur within six to nine months, with decisions following several months later. The December 2026 deadline leaves limited runway for a full Supreme Court cycle if the case has not yet been docketed. Any signals from the Court regarding case acceptance, combined with developments in related trade litigation, could shift trader positioning materially from current levels.

How active is this market?
$4.8M in lifetime turnover and $0 of resting liquidity puts this market in the top 2% by volume for courts contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
The market has been open for 8 months — long enough that the order book is mature and price is well-anchored to fundamentals.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.

Risk and regulatory note
Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
