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.

Nokia Beats Profit Expectations as AI and Cloud Growth Power Optical Sales

Nokia reported a stronger-than-expected third-quarter profit, lifted by booming demand for cloud infrastructure and AI-driven data center equipment following its acquisition of U.S. optical networking firm Infinera. Shares surged 10.6% to €5.20 — their highest level in over three years — adding €3 billion to the company’s market value.

Comparable operating profit reached €435 million ($507 million), well above analysts’ forecasts of €342 million, according to LSEG data. Group net sales rose 12% to €4.83 billion, supported by a 19% increase in optical network revenue on a constant currency basis. AI and cloud clients accounted for 6% of total sales and 14% of Nokia’s network infrastructure revenue.

CEO Justin Hotard said AI and data center demand “continues to accelerate,” underscoring the company’s growing focus beyond traditional mobile networks. Despite headwinds from U.S. tariffs, currency weakness, and losing a key AT&T 5G contract to Ericsson, Nokia upgraded its annual operating profit outlook to a range between €1.7 billion and €2.2 billion.
