What is a neocloud, and how is it different from a hyperscaler?

A neocloud is a cloud provider built from the ground up around GPU compute for AI training, inference and other accelerated workloads. Unlike hyperscalers such as AWS, Microsoft Azure and Google Cloud — which offer broad portfolios spanning storage, databases, enterprise software and general-purpose compute — neoclouds focus almost entirely on tightly integrated GPU clusters, high-bandwidth memory, low-latency networking and AI-optimised cooling. They typically operate at higher rack densities (often 40–130kW per rack), use NVIDIA reference architectures, and price aggressively against hyperscalers on dedicated GPU access.

Who are the main neocloud operators active in Australia in May 2026?

Five Australian-domiciled or active operators are deploying neocloud capacity onshore: Firmus Technologies (Project Southgate, 1.6GW target across Tasmania, Melbourne, Sydney, Canberra and Perth, hosted by CDC Data Centres), Sharon AI (NASDAQ-listed, deployments at NEXTDC M3 and S3), ResetData (Melbourne CBD, hosted by Centuria), Polaris Data Centre (Brisbane, HCF-certified) and Vultr (US-headquartered, with onshore Australian capacity). Internationally headquartered operators — CoreWeave, Crusoe, Lambda, Nebius, Nscale — service Australian customers remotely but have not yet announced onshore Australian deployments.

What did IREN and NVIDIA announce on 7 May 2026?

Two linked transactions. First, a five-year, US$3.4 billion AI infrastructure cloud services contract under which IREN provides NVIDIA with managed GPU cloud services for NVIDIA’s internal AI and research workloads, initially from approximately 60MW of air-cooled Blackwell capacity at IREN’s Childress, Texas data centres, with orchestration provided in collaboration with Mirantis. Second, a strategic partnership to deploy up to 5 gigawatts of NVIDIA DSX-aligned AI infrastructure across IREN’s global pipeline over time, anchored on IREN’s 2GW Sweetwater Texas campus. IREN issued NVIDIA a five-year warrant to purchase up to 30 million ordinary shares at US$70, representing up to US$2.1 billion of potential strategic investment, subject to regulatory approvals.
