Core42 expands US AI compute with 42MW Buffalo expansion
Lake Mariner site grows from 18MW to 60MW as G42 scales American infrastructure
#UAE #USA #datacentres – G42 Group’s sovereign cloud, AI infrastructure, and services company Core42, has expanded its Lake Mariner AI cluster in Buffalo, New York, from 18 Megawatts (MW) to 60MW, adding 42MW of high-performance AI compute capacity to its US footprint. The expansion adds NVIDIA and AMD infrastructure alongside the site’s existing AMD foundation, reinforcing Core42’s heterogeneous accelerator strategy. The Buffalo site already hosts Maximus, an AMD Instinct MI300X-powered supercomputer ranked 20th on the global TOP500 list, with 114.50 petaflops of LINPACK performance. Core42 now operates ten sites globally across the United States, Europe and the Middle East.
SO WHAT? – Core42’s Lake Mariner expansion is not just a capacity upgrade, it is also the physical expression of a bilateral strategic commitment. The US-UAE AI Acceleration Partnership binds the UAE to invest one dollar in US AI infrastructure for every dollar it deploys in Middle East data centres built on American technology. Core42’s growing US presence, now spanning New York, Texas, California and Minnesota, is how that commitment materialises on the ground. For G42, it also builds the case for Core42 as a significant global AI infrastructure player operating at hyperscale level.
KEY POINTS:
Core42 has expanded its Lake Mariner AI cluster in Buffalo, New York, from 18MW to 60MW, adding 42MW of AI compute capacity and tripling the site’s total power footprint. The expansion adds both NVIDIA and AMD hardware to the existing AMD-based infrastructure.
The Lake Mariner site hosts Maximus, an AMD Instinct MI300X-based supercomputer cluster powered by over 9,000 GPUs, ranked 20th on the global TOP500 supercomputing list with a LINPACK performance of 114.50 petaflops and a theoretical peak of 251.15 petaflops.
Core42’s broader US footprint now spans Buffalo and Minneapolis in New York and Minnesota, Dallas in Texas, and Sunnyvale and Stockton in California, including the Condor Galaxy supercomputer network developed in collaboration with AI chip company Cerebras.
The Minneapolis presence includes a 20MW office-to-data centre conversion in downtown Minneapolis, at 1001 Third Avenue South.
Core42’s AI Cloud platform, introduced in October 2025, serves as the access layer across its distributed infrastructure, allowing customers to provision compute across jurisdictions under a consistent operating model supporting the full AI lifecycle from training and fine-tuning through to real-time inference.
The US expansion is underpinned by the US-UAE AI Acceleration Partnership, under which the UAE commits to invest one dollar in US AI infrastructure for every dollar it invests in Middle East data centres built on American technology.
Core42 established its European headquarters in Dublin in 2025 and expanded AI compute deployments across Italy and France. Alongside the continued US capacity growth, this brings its total operational site count to ten globally with additional deployments planned for 2026.
The company’s heterogeneous infrastructure strategy runs workloads across NVIDIA, AMD and Cerebras hardware. The heterogeneous infrastructure is designed to enable workload-optimised deployment for both frontier model training and high-speed inference at production scale, giving customers flexibility in price-performance configuration.
ZOOM OUT – The Lake Mariner site's credentials were established in November 2025, when Core42 unveiled Maximus-01: the world's 20th most powerful supercomputer as ranked by the TOP500 list. Powered by more than 9,000 AMD Instinct MI300X GPUs and housed within US energy company TeraWulf's Lake Mariner data centre campus on the shores of Lake Ontario, Maximus delivers a LINPACK performance of 114.50 petaflops and a theoretical peak of 251.15 petaflops. The TOP500 placement served a dual purpose: validating Core42's technical capability to deploy and operate world-class supercomputing infrastructure, and signalling G42's serious and growing commitment to build-out US AI infrastructure.
