US stock futures edged lower on Tuesday as the government shutdown stretched into a seventh day after competing Democrat and Republican funding proposals failed in the Senate. Democratic leader Chuck Schumer also dismissed President Donald Trump’s claim that talks with Democrats were ongoing. Still, Wall Street started the week on a strong footing, with the S&P 500 and Nasdaq Composite rising 0.36% and 0.71% to new record highs, while the Dow slipped 0.14%, ending a six-day winning streak. Gains were driven by AI-related deal activity and expectations of a Federal Reserve rate cut. AMD soared 23.7% after unveiling a multiyear agreement to supply AI chips to OpenAI, which could acquire up to a 10% stake in the company. Other major tech stocks also climbed, including Tesla (5.5%), Microsoft (2.2%), and Palantir Technologies (3.7%).
