03 Oct 2025 Evaluate

The US markets ended higher on Thursday, supported by buying among tech stocks as continued optimism about the artificial intelligence (AI) kept the sentiments upbeat. The strength among AI stocks came after reports of OpenAI completed a deal placing a $500 billion valuation on the company. With the sale of about $6.6 billion worth of stock by current and former employees, the ChatGPT owner has surpassed Elon Musk's SpaceX as world's most valuable privately-owned company. Meanwhile, traders have shrugged off concerns about the economic impact of the ongoing U.S. government shutdown, which entered its second day with no signs of an imminent resolution.

On the sectoral front, significant strength has been seen among semiconductor stocks driving the Philadelphia Semiconductor Index up by 1.9 percent to a record closing high. Besides, notable strength emerged among airline stocks, as reflected by the 1.2 percent gain posted by the NYSE Arca Airline Index.

Dow Jones Industrial Average rose 78.62 points or 0.17 percent to 46,519.72, Nasdaq climbed 88.89 points or 0.39 percent to 22,844.05 and S&P 500 inched up 4.15 points or 0.06 percent to 6,715.35.
