Sheath those bad boys— Jim Cramer (@jimcramer) August 11, 2026 During CoreWeave's second-quarter earnings call, CFO Nitin Agrawal said demand remains "exceptionally strong" across its customer base, with "demand from multiple customers for each GPU we bring online." CEO Mike Intrator said pricing and margins for Nvidia's Blackwell and Vera Rubin chips are "setting new highs," while the company's near-term capacity remains "effectively sold out." Intrator added that contracts signed in the quarter carried contribution margins 5 to 10 percentage points above recent quarters, a dynamic he tied directly to customer demand for Nvidia-powered infrastructure.
