2025-10-06 20:01 By Mojdeh Kazemi 1 min. read

The S&P 500 and Nasdaq 100 extended record closes on Monday, rising 0.4% and 0.8%, fueled by AI-related dealmaking that boosted investor sentiment despite the US government shutdown entering its second week.

The Dow Jones slipped 65 points, dragged down by Home Depot and Verizon.

AMD surged 23.7% after announcing a multiyear deal to supply AI chips to OpenAI, with an option for the company to acquire up to 10% of AMD, fueling optimism for broader M&A activity.

Comerica jumped 13.7% following a $10.9 billion all-stock acquisition agreement with Fifth Third Bancorp.

Investors largely brushed off the shutdown, which has delayed key economic data like the jobs report, focusing instead on strong earnings prospects and potential Federal Reserve rate cuts.

Mega-cap stocks were mixed, with Microsoft (+2.2%), Tesla (+5.4%), Alphabet (+2%) up, while Nvidia (-1.1%) fell.
