Should the Supreme Court rule against Trump’s tariffs, it could threaten one-third of his proposed military budget

Posted on by

The U.S. Supreme Court may issue a ruling as early as Friday regarding whether President Trump’s tariff system is unconstitutional. Should the court invalidate his trade policies, it could put at risk up to one-third of Trump’s recently proposed military budget, per a social media post from the president.

Trump stated he intends to raise U.S. military spending from $1 trillion to $1.5 trillion. “I would stick with the $1 Trillion figure, but thanks to Tariffs and the massive revenue they generate, we can easily reach the $1.5 Trillion Dollar mark.”

Most analysts, though, anticipate the court will strike down his tariff system or at least limit it. During oral arguments, argued that the White House holds the authority to levy trade taxes without Congress’s approval under the International Emergency Economic Powers Act (IEEPA).

“Betting markets indicate a strong likelihood the White House will lose its appeal, which could result in a wave of tariffs—including the so-called ‘reciprocal’ duties on the E.U., China, and other nations—being invalidated,” ING informed its clients in an email obtained by . assign only a 29% probability to Trump’s tariffs remaining in place; that figure drops to just 25% . 

Approximately to eliminate the tariffs. If their efforts succeed, the White House would need to find a way to refund all collected tariffs. That would be a significant challenge. Data from Bloomberg (provided to through Pantheon Macroeconomics) shows tariff revenue is currently being generated at a monthly rate of $30.4 billion, translating to an annualized $364.5 billion. (Notably, this sum is less than the additional $500 billion Trump aims to allocate to the military.)

Trump has previously cautioned that it would be “” if he were compelled to refund the tariffs. His alternative would be to utilize other presidential authorities to essentially reimpose as many tariffs as feasible—though Wall Street analysts predict this would result in an effective average tariff rate lower than the current one.

Defense Stocks Are Volatile

U.S. defense firm stocks dropped sharply yesterday for a distinct but connected reason: that could prohibit military supply chain companies from conducting stock buybacks or setting senior executive pay above $5 million if the White House .

“If seeks additional contracts with the U.S. government, they will not be permitted to conduct any more stock buybacks (which have cost tens of billions of dollars) until they get their operations in order. Our country comes first, and they will have to learn that the hard way!” .

S&P 500 futures were lower this morning following the index’s decline yesterday. Markets across Asia and Europe were generally down. Defense stocks are experiencing high volatility in response to Trump’s multiple statements.

“President Trump’s social media posts weighed on homebuilder and defense company shares,” Jim Reid and his team at informed clients this morning. 

“Defense contractors like (-5.50%), (-4.82%), and (-2.45%) fell on the news. However, there was potentially positive news for defense firms after the market closed: Trump called for increasing the 2027 U.S. defense budget from $1 trillion to $1.5 trillion. The current 2026 fiscal year budget stands at $901 billion. The renewed policy uncertainties left the S&P 500 down 0.34% at the close,” they stated.

In overnight trading, those stocks rebounded following Trump’s $1.5 trillion budget proposal. Northrop Grumman climbed 7.28%, Lockheed Martin gained 6.71%, and RTX (parent of Raytheon) rose 5%.

Should the court rule against Trump, those stocks are likely to drop sharply again, as the end of tariffs puts a large portion of the proposed Department of War budget at risk.
