Peter DeSantis
Title: SVP AI, Silicon Development and Quantum Computing Company: Amazon Industry: Technology
Following Andy Jassy’ s strategic restructure in early 2026, Peter has been elevated to lead the newly-unified Global AI Infrastructure division. Previously the architect of AWS Utility Computing, he is now responsible for the entire physical and silicon stack required to support Amazon’ s AGI ambitions. Peter’ s mandate is to break the cost curve of model training through the aggressive deployment of custom silicon, specifically the next-generation Trainium and Inferentia chips. He oversees the rapid construction of Amazon’ s new liquidcooled AI regions, ensuring the company can deliver supercomputing scale without relying solely on third-party GPUs. A deeply technical leader known for his focus on efficiency and undifferentiated heavy lifting, Peter is tasked with solving the massive energy and thermal challenges that bottleneck modern intelligence. His role positions him as the master builder of the machine that will power Amazon’ s future, bridging the gap between raw electricity and generative reasoning.
