U.S. stock futures experienced a minor decrease on Tuesday as investors prepared for the Federal Reserve's forthcoming monetary policy meeting. While the Fed is anticipated to maintain current interest rates, market participants will closely scrutinize Fed Chair Jerome Powell's remarks in light of ongoing tariff uncertainties and mounting pressure from President Donald Trump to lower rates. On another front, Treasury Secretary Scott Bessent indicated on Monday that the U.S. is "very close to some deals," supporting President Trump's weekend assertions that trade agreements might be concluded as soon as this week. In corporate developments, Palantir Technologies saw its shares fall 9% in after-hours trading, despite surpassing first-quarter revenue expectations. In Monday's regular trading session, the Dow Jones Industrial Average decreased by 0.24%, the S&P 500 slipped 0.64%, and the Nasdaq Composite dropped 0.74%. Investor sentiment weakened due to stalled trade discussions and new threats from Trump, who suggested imposing a 100% levy on foreign films.
