What happenedCoreWeave fell about 12% on Friday, its second big drop in three days, as investors focused on the AI cloud provider’s roughly $50 billion of debt.

OXY16 Oct 2026
Oil above $100 lifts energy stocks
What happenedEnergy was the best sector on Friday (up about 2.5%) as WTI crude climbed above $101 a barrel on Middle East supply risks.
