Credo faces interconnect competition as Rubin Ultra develops CPO and copper solutions
Wednesday, February 4, 2026 at 11:27 AM
Speculation regarding the adoption of Co-Packaged Optics (CPO) versus copper interconnect solutions for NVIDIA's upcoming Rubin Ultra platform suggests potential market share risks for Credo. While Credo is expanding into the competitive optical market, the shift toward integrated CPO in AI infrastructure could impact their traditional interconnect business.
Context
Nvidia's upcoming Rubin Ultra platform, slated for 2H 2027, represents a major inflection point for AI interconnect technology. Nvidia is simultaneously developing Co-Packaged Optics (CPO) and high-density copper solutions to support a massive 576-GPU scale-up domain. This dual-track strategy creates structural risk for Credo Technology Group, as the transition to integrated CPO or PCB-based backplanes in the "Kyber" rack could displace the discrete copper Active Electrical Cables (AEC) that currently anchor Credo's growth.
While Credo is aggressively pivoting by aiming to double its optical revenue in fiscal 2026, it faces a significantly more crowded competitive landscape. The company recently launched its 1.6T optical DSP and ZeroFlap transceiver line to diversify, but these products must compete with entrenched incumbents in a sector with historically tighter margins. If Nvidia’s CPO architecture becomes the industry standard for next-generation AI factories, Credo’s specialized lead in the copper market may face long-term obsolescence.
