Nvidia denied a SemiAnalysis report claiming its Kyber NVL144 AI server rack was delayed from 2027 to 2028. Shares rose about 1% after the denial.

The reported delay adds to concerns that Nvidia's breakneck annual release cadence is colliding with manufacturing limits.

Nvidia's Kyber NVL144 AI rack system is delayed to 2028 due to PCB manufacturing issues, with the NVL72x2 design canceled and Rubin Ultra on hold.

Is Nvidia’s Kyber rack delayed, and what does it mean for the AI infrastructure market?
