Multiple credible sources directly report that prediction market data estimated a 74% probability that the U.S. Supreme Court would strike down tariffs imposed by Donald Trump. The Chosun article explicitly cites the 74% figure and clearly attributes it to prediction market estimates. Similarly, the Benzinga and MSN articles discuss prediction market assessments and probabilities indicating a high likelihood of an unfavorable ruling for Trump, which aligns closely with the 74% figure. Additional legal analysis from EisnerAmper confirms that prediction market data has been referenced in coverage of this case, lending further credibility. None of the reviewed sources contradict this figure, though some sources address related legal or procedural contexts without mentioning prediction markets. Given the convergence of multiple independent reports—two of which name or strongly imply the specific 74% probability—and the absence of substantive contrary evidence, the claim is highly likely to be true. The authority levels of the sources are moderate to high, with direct relevance to prediction market data and the Supreme Court case, supporting a high-confidence 'likely_true' assessment.
