Jensen refutes Vera Rubin's delay, continuing Nvidia's running rebuttal of the rumor mill

Jensen Huang’s forceful denial of Vera Rubin (Blackwell Ultra) delays in Tokyo is a calibrated move to quash market jitters. Technically, on-time volume ramp will pressure the entire AI stack—from liquid cooling to NVLink—to accelerate upgrades, with TSMC’s CoWoS capacity emerging as the critical choke point. On compliance, tightening U.S. export controls compel Nvidia to reconfigure test and assembly across the U.S., Taiwan, China, and Southeast Asia, likely inflating operational costs by 15–20%. Rivals like AMD and Intel may push MI300X or Gaudi3 as alternatives, but without CUDA’s ecosystem moat, their impact remains marginal short-term. Over the next 18 months, Blackwell Ultra’s delivery reliability will dictate AI cluster deployment cadence—and any slippage could trigger a sector-wide reassessment of compute availability and capex timing.
