Credo is a main winner if the story @HyungsokAhn describes proves true, in which copper, pluggables, legacy power and testing benefit while co-packaged optics and 800VDC lose out. x.comÂ
Credo Technology's copper interconnects should do well after SemiAnalysis reported that Nvidia's Kyber NVL144 rack has been delayed by more than 12 months to 2028 and its NVL72x2 back-to-back architecture was cancelled, leaving Rubin Ultra with a limited scale-up domain. x.comÂ
POET Technologies and Sivers, as co-packaged optics pure plays, lose because CPO adoption has moved right by a full generation. SemiAnalysis reports Nvidia's flagship Kyber NVL144 rack is delayed over 12 months to 2028 and its NVL72x2 backup was cancelled, while optical scale-up won't arrive until Feynman. Packaging and interconnect hit physical walls in the same cycle, and the entire thesis for these names rests on CPO timing. x.comÂ
Alphabet and Broadcom own the 2027 window because their TPU optical-switching scale-up is the only proven alternative as Nvidia hits packaging and interconnect walls. Per SemiAnalysis, Nvidia's flagship Kyber NVL144 rack slipped over 12 months to 2028 and its NVL72x2 backup was cancelled, while the 2-die Rubin Ultra delivers about half the per-package performance and co-packaged optics won't come until Feynman. That breaks Nvidia's new-rack-every-year promise, the core of its moat premium. x.comÂ
NVIDIA's near-term revenue is safe from the Rubin delay rumors, which concern Rubin Ultra and its Kyber rack, not base Vera Rubin. Rubin Ultra reportedly dropped from four chiplets to two over manufacturing concerns, and Kyber's PCB midplane is hard to make defect-free. The base Vera Rubin NVL72 runs on the existing Oberon rack and is ramping. Jensen Huang's $1T of Blackwell and Vera Rubin orders through 2027 does not depend on Rubin Ultra, which still targets 2027 via a 2+2 board design. x.comÂ
Copper connectivity stays in Nvidia's racks longer than anyone modeled, a win for Amphenol and Credo. Per @SemiAnalysis_, the Kyber NVL144 rack is delayed more than 12 months to 2028 because its PCB midplane cannot be made at scale, and the NVL72x2 backup was cancelled. Co-packaged optics will not arrive until the Feynman generation, so the shift away from copper in scale-up moves out with it. x.comÂ
G2AIStack's reported component yield and capacity bottlenecks make NVIDIA's Rubin shipment outlook look dire. It says Rubin system expectations were cut from roughly 10,000 to around 5,000, citing GPUs, orthogonal backplanes and power systems; its ODM checks indicate shipments are falling short. x.comÂ
Co-packaged optics adoption is a matter of when, not if, so any further drop in optics stocks on NVIDIA's delay could be a great entry for those who missed the rally. SemiAnalysis reports NVIDIA's Kyber NVL144 rack has been delayed more than 12 months to 2028 and its NVL72x2 back-to-back architecture cancelled, leaving Rubin Ultra with a limited scale-up domain. x.comÂ
Broadcom faces more accelerator share risk than Nvidia, a key caveat for its AI case. Nvidia's strengths span silicon, systems and networking co-design, and software and ecosystem, while Broadcom's revolve around silicon and packaging IP, making it easier to take accelerator share from Broadcom. Broadcom's switch silicon business also faces some disruption risk from optical circuit switches. x.comÂ
Credo Technology sits right in the middle of the AI networking, connectivity and photonics theme, and Wall Street has just handed over an easy opportunity in it. The AI connectivity thesis keeps playing out across photonics, with FY26 revenue up 206% at 68% non-GAAP gross margins. x.comÂ
