IREN Limited IREN shares have gained 11.7% in the past month as its shift from Bitcoin mining toward AI cloud infrastructure gathers commercial momentum. New contracts and a completed customer handoff have improved visibility around the transition.
The question for investors is whether delivery can keep pace with the expectations now embedded in the stock. Contracted demand is rising quickly, but legacy mining pressure and a richer valuation leave less room for execution delays.
IREN's AI Contracts Add Revenue Visibility
IREN signed $2.8 billion of new multi-year cloud services contracts in July. The agreements span bare metal and managed cloud services, and the portfolio's weighted average contract term is roughly four years.
Following those agreements, about 85% of IREN's year-end 2026 AI Cloud annualized run-rate revenue target was under contract. The company also raised that target to more than $4 billion from $3.7 billion, giving the expansion a clearer revenue bridge as new capacity comes online.
IREN's Delivery Milestones Bolster Execution
Microsoft Corporation MSFT accepted Horizon 1 at IREN's Childress campus. Microsoft operates Azure AI infrastructure, and Horizon 1 is the first of four 50-MW deployments tied to IREN's five-year, $9.7 billion Microsoft agreement. Horizons 2-4 remain scheduled for 2026.
NVIDIA Corporation NVDA separately awarded IREN Exemplar Cloud status for the GB300 NVL72 deployment at Horizon 1. NVIDIA describes GB300 NVL72 as a liquid-cooled rack-scale system built around 72 Blackwell Ultra GPUs, making the designation another marker of IREN's ability to bring advanced AI capacity into service.
IREN Still Faces a Mining Revenue Air Pocket
Third-quarter fiscal 2026 AI Cloud Services revenues increased to $33.6 million from $3.6 million a year earlier. The newer business is scaling rapidly, but Bitcoin mining still supplied most of the quarterly revenue base.
Bitcoin mining revenues fell 21.3% year over year to $111.2 million from $141.2 million. That gap highlights the transition risk as mining declines before the larger Microsoft and other GPU deployments are fully reflected in reported revenues.
IREN's Valuation Raises the Bar for Execution
IREN trades at 4.59X forward 12-month sales, above the Zacks sub-industry's 2.58X and its own five-year median of 2.33X. The premium signals that investors are already assigning substantial value to the AI cloud ramp.
That makes delivery timing increasingly important. Further share-price gains may depend more on commissioned capacity, customer acceptance and recurring revenue conversion than on contract announcements alone.

IREN's Mixed Style Signals Temper the Rally
The bottom line is that IREN's monthly gain now coincides with both contract wins and a completed customer acceptance milestone, but execution remains the central test. The stock currently carries a Zacks Rank #3 (Hold), which points to a more balanced short-term setup than the top-ranked stocks. You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.
IREN has a Growth Score of B, supporting its growth profile, but a Value Score of D, Momentum Score of F and VGM Score of D. Those mixed Style Scores suggest the stock's growth characteristics are more favorable than its valuation and momentum profile, reinforcing the case for measured expectations as the AI cloud buildout advances.
