IREN says 2026 capacity sold out as late-stage 2027 deals advance
- IREN states 2026 capacity is largely sold out with $4 billion contracted ARR
- Late-stage discussions underway for 2027-2028 capacity at >$20 million/MW
- Microsoft Horizon 1 deployed; Nvidia validates Mirantis software layer
- Company raised $6.5 billion in GPU financing in last three months
- Strategy focuses on strategic merit and long-term economics over speed

IREN Ltd. (NASDAQ: IREN) told investors that its 2026 data center capacity is largely sold out, shifting focus to late-stage discussions for 2027 and 2028 buildouts.
Co-CEO Daniel Roberts stated that the company has reached $4 billion in contracted annual recurring revenue (ARR) for 2026, with $1 billion already operational. The firm is now prioritizing strategic merit and long-term economics over speed for future contracts.
Microsoft delivery and Nvidia validation
The company’s vertical integration strategy remains anchored by key partnerships. IREN delivered Horizon 1, the first of four planned 50-megawatt AI cloud deployments under its Microsoft contract, during the quarter. Microsoft is now running AI workloads on this infrastructure.
Additionally, Nvidia extended its validation to the software layer through Mirantis, which IREN recently acquired. Mirantis was named an inaugural Nvidia Certified Hypervisor, enabling IREN to offer managed AI cloud services alongside bare-metal GPU infrastructure.
| Milestone | Detail |
|---|---|
| Horizon 1 delivery | First of four planned 50-megawatt AI cloud deployments under Microsoft contract |
| 2026 contracted ARR | $4 billion total; $1 billion already operational |
| Nvidia Cloud ARR | $700 million expected to ramp in 2027 |
| Mirantis certification | Named inaugural Nvidia Certified Hypervisor |
Contract playbook and pricing
Roberts described a deliberate framework for weighing new contracts based on counterparty strategic merit, economics, and potential for managed services. He noted that signing deals is not the bottleneck; bringing GPUs online is.
COO Kent Draper cited live conversations showing contracts above $20 million per megawatt of IT load. Roberts added that these are 3- to 5-year deals rather than spot capacity. Discussions with prospective customers have advanced well past early stages for a significant portion of 2027 capacity.
Financing and global demand
IREN raised $6.5 billion in GPU financing over the last three months, covering both ends of the credit spectrum. Prepayments from newer contracts are helping finance the build-out. Draper noted that pricing in Spain and Australia has tracked with North America, reflecting a largely global market for compute.
What the Numbers Show
The gap between contracted ARR ($4 billion) and operational revenue ($1 billion) highlights a deployment-heavy phase for IREN. With 2026 capacity sold out, the immediate growth driver shifts to execution of these contracts and conversion of 2027-2028 discussions into signed deals. The high pricing floor (> $20 million/MW) suggests strong demand persistence despite the supply constraints management cited.
How will IREN's shift from speed to strategic merit in contract negotiations impact its ability to secure the remaining 2027-2028 capacity against competitors?
What specific execution risks does IREN face in bridging the $3 billion gap between contracted ARR and operational revenue by 2026?
Will the global parity in pricing observed in Spain and Australia persist as local regulatory or energy constraints tighten in those regions?
