Expands Buffalo AI cluster capacity from 18MW to 60MW
Core42, a G42 company specializing in sovereign cloud and AI infrastructure, today announced a 42MW expansion of its U.S. AI infrastructure at the Lake Mariner site in New York, increasing total site capacity from 18MW to 60MW of high-performance AI production infrastructure.
The expansion reflects G42’s continued capital investment in scaling AI infrastructure across the United States.
Lake Mariner serves as a North American AI infrastructure hub within Core42’s globally distributed network. The facility previously demonstrated architectural performance with the AMD Instinct MI300-based Maximus cluster securing a Top-20 ranking on the global TOP500 supercomputing list.
“Increasing our U.S. capacity at Lake Mariner strengthens our ability to serve hyperscale, AI-native and large enterprise workloads, and further extends the build out of our AI infrastructure globally,” stated Talal M. Al Kaissi, Chief Executive Officer, Core42.
Expansion
The Buffalo expansion forms part of Core42’s broader international infrastructure buildout, spanning the United States, Europe and the Middle East.
Core42’s AI Cloud platform, which was introduced in October 2025, is the access layer to the distributed AI infrastructure, allowing customers to provision computing across jurisdictions under a consistent operating model.
The platform supports the full AI lifecycle, from large-scale training and fine-tuning to real-time inference, leveraging heterogeneous infrastructure with multiple options to help drive optimal price-performance.
