The U.S. Supreme Court will not announce the ruling on Trump's tariffs case today. Here's the key point — courts typically do not disclose the specific day they will issue opinions in advance, only announcing a unified "Opinion Release Date." On this announced date, the court will release rulings on multiple cases simultaneously, rather than one by one. This mechanism is worth noting for traders who follow policy developments, as the final implementation of tariff policies could influence the overall market trend.
