The reorganisation, announced on 17 September, ends a dual-brand structure that had persisted since Submer acquired Radian Arc earlier this year. InferX and RadianX now operate as product families inside Radian Arc rather than as separate market-facing names. InferX retains its NVIDIA Cloud Partner status and covers sovereign GPU and AI services; RadianX covers cloud gaming, routing low-latency workloads through telecom operator networks.
The timing reflects a structural shift in how AI compute is being used. Inference — running trained models against live requests — has moved from roughly one-third of all AI compute in 2023 to approximately two-thirds in 2026, according to Deloitte analysis. Where training clusters can sit in a handful of centralised facilities, inference workloads run continuously and must satisfy the data residency rules of each jurisdiction they operate in, pushing capacity requirements outward toward edge and telecom locations.
Radian Arc already has more than 90 telecom and edge partners with thousands of GPUs in operation across North America, Europe, the UK, India, the Middle East and Asia-Pacific. The platform routes workloads between core data centres, partner facilities and telecom operator networks based on latency requirements, data residency constraints and cost per token.
David Cook, CEO of Radian Arc, framed the consolidation as a commercial simplification. "Our objective is to be simple to do business with," he said. "Under one brand, a customer only needs to know Radian Arc. From there, the conversation centres on what application you're running, how much capacity it needs and which country it needs to run in. We can provide an outcome-optimised solution for most answers to these questions, and buyers do not expect that from a single supplier."
Submer Group, founded in Barcelona in 2015, now spans the full AI infrastructure stack from land and power through liquid-cooled thermal architectures, modular data centre development and cloud services. The group has deployed over 500 MW of liquid-cooled infrastructure and holds 8 GW-plus of powered land globally.
