Prediction market traders bet against Trump's tariffs as Supreme Court ruling looms

Traders on prediction platforms Kalshi and Polymarket are betting that the nation’s highest court is unlikely to rule in favor of President Donald Trump's tariffs.

Traders on Kalshi now give a nearly 32% chance that the Supreme Court will side with Trump’s tariff plan, down 14 points after oral arguments in November signaled potential skepticism from the justices.

The trading volume, or the total dollar amount wagered on this market, is a little more than $3 million.
