In a move set to redefine the landscape of artificial intelligence, Microsoft has sealed a landmark five-year agreement with data-center operator IREN, valued at $9.7 billion. This pact grants Microsoft guaranteed access to advanced Nvidia chips, a critical step in addressing the tech giant’s persistent struggle with AI compute capacity bottlenecks—an issue that has increasingly limited its ability to harness the rapid growth in AI applications such as ChatGPT.
The announcement sparked immediate market enthusiasm, propelling IREN shares up more than 20% in Monday’s pre-market session. Meanwhile, Dell, slated to supply IREN with Nvidia’s powerful GB300 chips under a $5.8 billion contract, saw a 5% boost in its stock price—reflecting the industry’s growing confidence in AI infrastructure investments.
Microsoft’s Response to Surging AI Demand
The deal comes at a crucial time for Microsoft. Last week, CFO Amy Hood revealed that the company’s AI capacity crunch is now expected to stretch into mid-2026, revising previous estimates for improvement by 2025’s end. This shortage, shared across other technology giants, has left firms scrambling for the compute power necessary to support advanced AI workloads.
By partnering with IREN, Microsoft sidesteps the need to build new data centers or secure additional power sources—a move that not only accelerates its response to immediate AI demand but also allows the company to minimize heavy capital expenditures on rapidly depreciating chips.
What Makes the IREN Deal Unique?
IREN, now valued at $16.52 billion after a meteoric rally in its stock, operates multiple North American data centers with a total capacity of 2,910 megawatts, all powered by renewable energy. The Nvidia processors secured under this agreement will be rolled out in phases through 2026 at IREN’s 750-megawatt Childress, Texas campus—a location set to house new liquid-cooled data centers, expected to add about 200 megawatts of IT capacity.
This focus on sustainability and scalability positions Microsoft to dramatically expand its AI infrastructure while remaining adaptable as newer, more powerful chip technologies emerge.
Satya’s ability to context switch between infrastructure, hardware innovation cycles, and software is crazy impressive.

Financing and Risks: New Benchmarks for AI Infrastructure
IREN’s regulatory filings confirm that Microsoft’s upfront payment will help finance a substantial portion of Dell’s $5.8 billion contract. Importantly, the deal contains a significant clause: Microsoft retains the right to walk away if IREN fails to deliver on schedule. The pressure to meet milestones is high, as the compute capacity crunch continues to weigh heavily on technology leaders.
