Premarket, Alphabet is up roughly 2% after announcing Gemini 4 Argon, Constellation Energy is up around 4% following a 20-year nuclear-power agreement with Amazon, and Vicor is sharply higher after raising guidance, while Micron is slightly lower despite its blowout report. Today's key economic releases are initial jobless claims, S&P manufacturing PMI and ISM Manufacturing, with Fed commentary also in focus ahead of Friday's September jobs report; earnings include Accenture before the bell and Nike after the close. Treasury yields remain the biggest immediate risk to equities, while AI/semiconductor strength, oil and incoming labor data will determine whether tech can continue offsetting broader macro pressure. 01-OCT-2026 06:52 AM ET
