IREN Climbs 6%, Nebius Jumps 10% as GPU Rental Rates Head Higher; CoreWeave Slips
Nebius Group (NBIS) announced higher GPU rental rates, lifting its stock 10% and IREN Limited (IREN) 6%. CoreWeave (CRWV) fell 2% due to debt and capacity concerns. Analysts view this as a neocloud-specific repricing, not a broad sector rally. QQQ and DTCR ETFs showed mixed performance.
