IREN Limited's Sweetwater Hub: Can It Fuel IREN's AI Expansion Plans?
Read MoreHide Full Article
Key Takeaways
IREN plans roughly 2 GW of gross power capacity across Sweetwater 1 and Sweetwater 2.
IREN aims to replicate Sweetwater's liquid-cooled design across future AI infrastructure projects.
Execution depends on capital, ERCOT grid access and turning planned capacity into AI revenue.
IREN Limited (IREN - Free Report) is positioning its Sweetwater campus as a major long-term AI infrastructure platform. Sweetwater 1 is planned with 1.4 GW of gross capacity, while Sweetwater 2 adds another 600 MW, giving the campus roughly 2 GW of planned gross power capacity. The scale is significant as IREN seeks to own and operate data centers, AI compute and software.
Sweetwater also has strategic importance beyond its size. IREN plans to replicate the liquid-cooled data-center design developed for Sweetwater 1 across Sweetwater 2, Kiowa and other planned developments. The standardized design is intended to support successive GPU generations, evolving cooling requirements and 800VDC power architectures, potentially making Sweetwater a blueprint for IREN’s broader AI expansion.
Strong AI demand and improving contract economics add to the growth potential. IREN said recent three-year contracts are generating more than $20 million per IT MW, with discussions at around $25 million per MW. However, these figures apply to broader AI Cloud activity and are not specific to Sweetwater.
Execution remains a major consideration. Sweetwater requires substantial capital, while timely ERCOT grid connections and electricity availability remain critical. IREN’s contractual commitments reached $13.81 billion as of June 30, 2026, highlighting the scale of its expansion.
Sweetwater could become a major growth driver for IREN. Its large capacity base, liquid-cooled design and strong AI demand provide significant upside, but converting planned power capacity into operational, revenue-generating AI infrastructure remains the key test.
How Are IREN’s Competitors Expanding?
CoreWeave (CRWV - Free Report) is targeting surging AI demand by rapidly deploying the latest NVIDIA infrastructure and broadening beyond GPU capacity into software. Its Forge platform supports AI model development and management, while expanding enterprise adoption and large customer commitments strengthen utilization of its AI cloud infrastructure.
Nebius (NBIS - Free Report) is expanding its full-stack AI cloud through new data-center capacity and deeper NVIDIA collaboration. The company plans to deploy more than 5 GW of NVIDIA systems by 2030, while investments such as its UK buildout and secured financing support faster global capacity additions.
IREN’s Price Performance, Valuation and Estimates
Shares of IREN have risen 12.1% over the past six months, outperforming the broader industry but underperforming the S&P 500 composite.
