Nov 3 – The dollar weakened on Tuesday, weighed down by concerns over the outlook for artificial intelligence investment and investor caution ahead of the U.S. midterm elections. Apple (AAPL.O) warned on Monday that the cost of running AI tools would squeeze profit margins, deepening market worries about the sustainability of AI investment. AI model developer Anthropic reported an operating loss in the third quarter due to a high-cost data center agreement, while rival OpenAI's latest funding round raised less than half of its initial $30 billion target. For the dollar, rising oil prices offered some support. International oil prices turned higher on Monday after the United States struck Iran's Qeshm Island. However, uncertainty over the outcome of the U.S. midterm elections kept investors cautious. The dollar index DXY fell 0.12% on the day to 101.684, after touching 101.426 on Monday, its lowest level in a month.
