IREN delivers 50MW Horizon 1 to Microsoft, earns NVIDIA Exemplar status

Microsoft accepted IREN's first 50MW direct-to-chip liquid-cooled data center on Aug. 13, converting 25 percent of the $9.7 billion cloud contract into delivered infrastructure and earning NVIDIA Exemplar Cloud certification for the GB300 NVL72 deployment.

"This demonstrates the strength of our vertically integrated model and our ability to execute complex AI infrastructure projects at speed and scale," Daniel Roberts, co-founder and co-CEO at IREN, said, crediting more than 3,000 site team members for the milestone.

Horizon 1 is the first of four identical 50MW facilities at IREN's Childress, Texas campus scheduled for delivery in 2026 under the five-year agreement announced in November 2025. NVIDIA tested the GB300 NVL72 deployment before granting Exemplar Cloud status, a program introduced in May 2025 that counts CoreWeave, Crusoe, and Lambda among its six certified partners. IREN also signed $2.8 billion in new multi-year AI Cloud contracts and raised its year-end 2026 annualized recurring revenue target to more than $4 billion, with roughly 85 percent already under contract.

The acceptance de-risks the largest revenue pipeline in IREN's transition from Bitcoin mining to AI infrastructure. Hyperscaler capital expenditure on data centers is projected to reach $697 billion in 2026, with AI workloads expected to represent 28 percent of the data center market by 2027, according to J.P. Morgan. IREN shares rose 3.8 percent in premarket trading to $45.73, implying an equity valuation of about $16.34 billion.

The 30-Fold Revenue Ramp

IREN's March-quarter AI-cloud revenue of $33.6 million annualizes to roughly $134.5 million, meaning the company must grow that figure about 30-fold to hit its $4 billion year-end target. A single accepted Horizon 1 site implies annual service value of roughly $485 million based on equal economics across the four Microsoft deployments — about 3.6 times the current AI-cloud run rate. The remaining three Horizon facilities now carry the bulk of near-term execution responsibility.

The company reported $144.8 million in total March-quarter revenue, with Bitcoin mining still the primary contributor. Cash stood at $2.21 billion at March 31, while nine-month investing cash outflow reached $2.61 billion, reflecting the capital intensity of the buildout. Management said roughly 95 percent of Microsoft-related GPU capital spending is expected to be funded through customer prepayments and GPU financing.

Neocloud Competition Heats Up

IREN joins a cluster of specialized cloud providers competing for hyperscaler AI infrastructure contracts. CoreWeave gained 47 percent in 2026 after a post-earnings rally, while Applied Digital rose about 27 percent. IREN's 16.7 percent gain in 2026 trails both peers, though the Microsoft acceptance and NVIDIA certification narrow the credibility gap. Earlier in August, Super Micro Computer landed a gigawatt-scale AI data center deal with SpaceX and xAI, showing the scale of demand for purpose-built infrastructure.

IREN trades at about 4.52 times forward sales, below Applied Digital's roughly 8.85 times but above CoreWeave's roughly 2.34 times. Analyst targets range from Goldman Sachs' Neutral at $50 to Cantor Fitzgerald's Overweight at $99. Jefferies initiated with a Buy and $79 target, citing IREN's "extraordinarily large long-term powered land bank."

The company's customer list now includes Microsoft, NVIDIA, Perplexity, and several AI software developers, alongside a separate five-year, $3.4 billion AI cloud agreement with NVIDIA. The Mirantis acquisition added software and cloud management capabilities, though investors will watch whether those additions improve margins and customer retention.

IREN's next earnings report is expected around Aug. 27, with analysts projecting revenue near $165 million and a per-share loss of $0.38. The three remaining Horizon deliveries, contracted revenue conversion, and financing terms will determine whether the stock's AI premium holds.
