CoreWeave is trading 5.3% down at $3.33, with no clear company-specific catalyst for the decline identified in available reporting. - On September 30, CoreWeave announced NVIDIA Vera Rubin NVL72 production availability with Cognition; coverage described the launch positively, so it does not explain the decline. - Treasury yields rose amid market pressure, but broad index declines were modest and available evidence does not establish this as the direct cause.
