(Reuters) - Wall Street's main indexes opened higher on Monday, building on last week's gains, as AMD's chip-supply tie-up with OpenAI became the latest in a series of AI deals and offset concerns around a prolonged federal government shutdown. The Dow Jones Industrial Average rose 17.8 points, or 0.04%, at the open to 46,776.04. The S&P 500 rose 18.1 points, or 0.27%, at the open to 6,733.86, while the Nasdaq Composite rose 113.8 points, or 0.50%, to 22,894.352.
