IREN tied to big GPU buildouts
IREN ($IREN) is being highlighted for AI HPC catalysts as its Sweetwater 1 project energizes this April, a step investors link to large GPU deployments (x.com). Social posts projecting scale point to a path to roughly 140,000 GPUs and a $3.4B run‑rate, with mentions of a $9.7B Microsoft arrangement and about 76,000 NVDA GB300s in the pipeline (x.com).
IREN’s Sweetwater 1 site is due to energize in April 2026, giving investors a fresh milestone to watch as the company pitches itself as a builder of large artificial-intelligence computing campuses. (sec.gov) IREN said on March 17, 2025 that Sweetwater 1 was being prepared for energization in April 2026, while Sweetwater 2 was targeted for 2027. The company’s Sweetwater page now lists Sweetwater 1 as “under construction” with 1,400 megawatts of planned power and Sweetwater 2 with 600 megawatts. (sec.gov) (iren.com) Those power figures matter because graphics processing units, the chips used to train and run artificial-intelligence models, consume huge amounts of electricity and cooling. IREN says its 2,000-megawatt Sweetwater campus is designed for air and liquid cooling and has direct fiber links for high-speed data traffic. (iren.com) The company has already tied a separate Texas campus to a named customer and a defined hardware plan. On November 2, 2025, IREN signed a Microsoft agreement worth about $9.7 billion through 2031 to provide dedicated graphics-processing-unit capacity at its Childress, Texas “Horizon” facilities. (sec.gov) IREN said that Microsoft contract uses NVIDIA GB300 chips, rolls out in four tranches during 2026, and represents about 200 megawatts of information-technology load. The company also said the deal carries a 20 percent prepayment and could add roughly $1.94 billion in annualized run-rate revenue when fully commissioned. (sec.gov) (iren.com) That helps explain why traders are linking Sweetwater’s April power milestone to future graphics-processing-unit deployments even though IREN has not publicly announced a Sweetwater customer contract on the scale of Microsoft’s Childress deal. IREN’s own materials describe Sweetwater as a flagship West Texas hub for artificial intelligence and high-performance computing, not just bitcoin mining. (iren.com 1) (iren.com 2) The company’s public disclosures support the broad expansion story, but not every social-media figure attached to it. IREN’s investor site lists a March 4, 2026 release titled “IREN Expands AI Cloud Capacity to 150,000 GPUs,” yet the accessible summary does not show the detailed mix of chip models or the exact site-by-site breakdown. (iren.com) IREN’s website also says the company has 810 megawatts operational, 2,100 megawatts under construction, and 1,600 megawatts in development across North America. Its build-to-suit page separately says it has 2.9 gigawatts of grid-connected power backing custom data-center projects. (iren.com 1) (iren.com 2) The near-term test is simple: whether Sweetwater 1 moves from “under construction” to live power in April 2026. If that switch happens on schedule, IREN will have turned another big block of contracted Texas electricity into a more concrete pitch for future chip clusters. (iren.com) (sec.gov)
