US equity futures fell for a third straight session Wednesday as higher yields raised concerns about corporate margins and consumer demand. S&P 500 and Dow contracts dropped about 0.5%, while technology weakness pushed Nasdaq 100 futures toward a nearly 1% decline. Oil and fuel prices extended gains as escalating strikes between the US and Iran reduced the likelihood of Middle Eastern oil exports resuming soon, adding to inflation concerns before the Federal Reserve meeting next week. Alphabet fell 2.3% after announcing a $15.1 billion Finland buildout, and Amazon lost 1.5% after another financing round in sterling. Meta gained 5% after unveiling a new AI agent.
