5C Group said it closed $605 million in new debt financing led by Brookfield Asset Management, giving the AI data center developer fresh capital to speed construction across its North American campus pipeline. The funding follows $835 million in equity and debt raised in 2025, along with additional capital secured before that, which the company said together are supporting the expansion of its AI infrastructure platform. The new proceeds are earmarked for priority sites across 5C's portfolio, including acquisition and construction of its Memphis campus and further development of its Ohio and Phoenix locations as they reach commercial and investment milestones. 5C builds large-scale AI campuses designed to combine compute, power, cooling, networking, software and operations in a single system, an approach aimed at serving increasingly dense AI workloads and adapting to changes in GPU architecture, liquid cooling (using fluid instead of air), rack-scale systems and AI deployment models. Chief Executive Officer Jonathan Ahdoot said the financing shows confidence in 5C's strategy and execution, while Brookfield's Hamish Kidd said the campuses are positioned to meet rising demand for advanced AI capacity. 5C says it has more than 1.5 gigawatts of roadmap capacity and infrastructure capable of powering hundreds of thousands of GPUs.
