Microsoft Signs $9.7 Billion Cloud Deal with IREN to Boost AI Computing Power

Microsoft has signed a $9.7 billion cloud computing deal with U.S.-based data center operator IREN to expand its artificial intelligence infrastructure and ease ongoing computing bottlenecks. The agreement, which includes access to Nvidia’s powerful GB300 chips, underscores the growing global demand for AI processing capacity.

Shares of IREN surged nearly 25% to a record high following the announcement before settling up around 10%. Dell Technologies, which will supply Nvidia’s advanced chips and related equipment to IREN, also gained about 1%. Under the five-year agreement, Microsoft will use roughly $5.8 billion worth of IREN’s computing hardware and infrastructure capacity.

The deal allows Microsoft to scale its AI operations without immediately building new data centers or acquiring additional power resources — key hurdles that have limited the company’s ability to meet soaring demand for applications like ChatGPT and Copilot. The approach also helps reduce heavy capital spending on rapidly depreciating hardware as newer processors enter the market.

IREN operates data centers across North America with a total capacity of 2,910 megawatts. The Nvidia chips will be deployed in phases through 2026 at the company’s 750-megawatt facility in Childress, Texas, which will include liquid-cooled centers providing 200 megawatts of new IT capacity.

The deal follows Microsoft’s recent $17.4 billion agreement with AI cloud provider Nebius and reflects the company’s strategy to leverage “neocloud” partners such as IREN and CoreWeave to expand capacity. IREN said Microsoft’s prepayment will help fund its $5.8 billion Dell contract, though the deal could be canceled if deadlines are missed.

The Global AI Buildout Accelerates as Tech Titans Drive Record Investment

The global race to build artificial intelligence infrastructure shows no sign of slowing, as technology giants and industrial firms alike pour trillions into data centers, chips, and computing power. Nvidia’s market value soared past $5 trillion this week — a milestone that underscores how central AI has become to the global economy.

In a whirlwind week for the tech sector, Microsoft and OpenAI struck a landmark deal expanding the ChatGPT maker’s fundraising capacity, while Amazon announced 14,000 corporate job cuts just days before its cloud division reported its fastest growth in nearly three years. Together, these developments highlight AI as the defining engine of modern corporate spending and stock market momentum.

AI’s impact now extends beyond Silicon Valley. Over 100 non-tech companies — from Honeywell and GE Vernova to Caterpillar — referenced data centers in their earnings calls, signaling how deeply AI demand is reshaping industrial supply chains. Caterpillar’s data center equipment sales jumped 31% last quarter, reflecting the sector’s explosive growth.

Goldman Sachs projects global AI-related infrastructure spending could reach up to $4 trillion by 2030. Microsoft, Amazon, Meta, and Alphabet are expected to collectively invest around $350 billion this year alone. Meanwhile, AI investment is fueling international trade, with the U.S. importing vast quantities of semiconductors from Taiwan, South Korea, and Vietnam.

Despite talk of an AI “bubble,” companies continue to ramp up spending. Apple plans to significantly boost AI investments, and Amazon is projecting capital expenditures of $125 billion in 2025. Economists say this phase of the AI revolution remains in its early stages — with innovation advancing faster than any technology cycle in recent history.

Western Digital and Seagate Surge as AI Infrastructure Demand Fuels Record Gains

Shares of data storage leaders Western Digital and Seagate have skyrocketed this year, outpacing the broader market as global demand for AI-driven infrastructure fuels unprecedented growth in hard drive sales. Both companies’ stocks have surged over 200% in 2025, reaching record highs amid a worldwide scramble to expand data storage capacity for artificial intelligence applications.

Western Digital shares rose more than 11% on Friday after the company forecast second-quarter earnings above Wall Street estimates. Analysts at J.P. Morgan noted that Western Digital has secured purchase orders from five of its largest customers through 2026, signaling strong confidence in sustained AI-related demand.

Seagate, a close rival, also projected revenue and profit above expectations earlier this week, pushing its stock up more than 22%. Both companies are now among the top three performers in the S&P 500 this year, trailing only Robinhood.

Smaller competitor Sandisk, spun off from Western Digital in February, has seen its shares soar fivefold since its debut and was up another 3.6% on Friday ahead of its upcoming earnings report.

The S&P 1500 tech hardware, storage, and peripherals sector—which includes all three companies—has climbed more than 12% this year, hitting an all-time high. As major tech firms like Alphabet, Microsoft, Meta, and Amazon ramp up capital spending on chips and data centers, analysts expect global AI infrastructure investments to reach up to $4 trillion by 2030.
