In late July 2026, Huawei announced its Atlas 950 SuperPod, a supernode claiming performance comparable to Nvidia’s GB200 and GB300 racks. While AMD promoted its open ROCm platform to challenge Nvidia’s CUDA dominance, Nvidia highlighted the rise of the Vulkan API and Mojo language as tools that allow models to run across diverse hardware, potentially eroding the CUDA monopoly. 

By mid-August, the difficulty of breaking Nvidia’s dominance became clearer in China. Despite Beijing’s push for domestic alternatives like Huawei’s Ascend chips, developers remain heavily reliant on Nvidia due to the established CUDA ecosystem. Transitioning to Huawei’s Compute Architecture for Neural Networks (CANN) requires extensive code rewriting. Experts note that moving workflows to Ascend could increase costs and time requirements by at least 50%. While open-source models like DeepSeek may be migrated by small teams within a month, complex models with restricted source code, such as Moonshot AI’s Kimi K3, could require approximately 10 engineers and over six months of additional work.

Nvidia CEO Jensen Huang warned that if large language models like DeepSeek V4 continue utilizing Huawei hardware instead of American technology, Nvidia could face losses of approximately $50 billion. This shift threatens the network effect of CUDA as a global standard. Amidst this competition, Nvidia announced plans to finance AI infrastructure expansion with $500 billion in capital alongside various partners. However, investors are weighing whether these massive investments will remain profitable if China’s focus on inexpensive open-weight models puts significant pricing pressure on the industry.
