Relationship unites CleanSpark’s U.S.-based power and land assets with Submer’s established global presence, to offer liquid-cooling and scalable data center infrastructure delivering AI solutions, with more than 1 GW in the current portfolio and a pipeline of more than 2 GW
LAS VEGAS, Oct. 28, 2025 /PRNewswire/ — CleanSpark, Inc. (Nasdaq: CLSK), America’s Bitcoin Miner® (the “Company”), today announced it is working with Submer, a global leader in sustainable, modular AI data center design and construction to evaluate opportunities for future collaboration.
The two companies are working together on an infrastructure platform that integrates power generation, data center development, and AI-service delivery. Under this framework, CleanSpark would focus on selecting, developing, building, and operating AI-focused campuses, while Submer will offer its technology and expertise in sustainable, modular data-center systems.
Founded in 2015, Submer is a global pioneer in liquid-cooled and prefabricated data center solutions. Its end-to-end capabilities, spanning from liquid-cooling systems and power modules to full facility builds, set new benchmarks in energy efficiency, density, and sustainability, making it an ideal partner for CleanSpark’s long-term growth strategy.
Matt Schultz, CleanSpark’s Chief Executive Officer and Chairman, said:
Submer has established itself as one of the most advanced and forward-thinking AI infrastructure firms in the industry,
“By combining our energy and land portfolio with Submer’s state-of-the-art AI deployment and liquid cooling expertise, we are positioned to deliver AI capacity at gigawatt scale, faster, cleaner, and more efficiently than traditional approaches. This relationship perfectly aligns with our vision of transforming CleanSpark’s infrastructure platform into the backbone of the next era of intelligent computing.”
Patrick Smets, Chief Executive Officer of Submer, said:
This collaboration represents a pivotal step toward scaling AI infrastructure globally,
“CleanSpark’s unmatched expertise in site development, power strategy, and large-scale infrastructure delivery and operations combined with Submer’s ability to design and deploy high-density AI environments rapidly and efficiently, creates a new blueprint for sustainable, high-performance AI compute at scale. Together, we’re building the industrial foundation for the Age of Intelligence and building the infrastructure that will sustain it.”
Jeffrey Thomas, CleanSpark’s Senior Vice President of AI Data Centers, said:
Working in conjunction with accomplished technical partners is critical for successful tenant and customer relationships,
“Submer already has received approvals for its designs for leading reference architectures. Working with Submer accelerates our capability and ability to scale at pace, and we look to conclude definitive agreements in the coming weeks.”
CleanSpark’s expansion into AI infrastructure builds upon its proven, vertically integrated model and track record of rapid site development, allowing it to capitalize on the global surge in demand for digital infrastructure driven by artificial intelligence and compute-intensive applications.
CleanSpark and Submer acknowledge the fast-moving nature of the sector and have agreed to collaborate under a non-binding framework to evaluate opportunities for a definitive agreement and the development of AI data centers in North America.
