Wall Street traders defied calls for a breather after a $15 trillion stock rally from April lows, with Nvidia Corp. boosting optimism on artificial intelligence after pledging to invest as much as $100 billion in OpenAI. Tech led gains in the S&P 500, with the US equity benchmark hitting its 28th record this year. The world's largest chipmaker rallied about 4%. Its investment is intended to help OpenAI build data centers with a capacity of 10 gigawatts of power using Nvidia's advanced AI chips to train and deploy OpenAI's models. For a closer look at the market landscape, we hear from Michael Green, Chief Strategist at Simplify Asset Management.

Meanwhile, Asian stocks posted a modest gain at the open. Gauges in Australia and South Korea rose while equity-index futures for Hong Kong — facing its most damaging typhoon since 2018 — were flat.
