The Hegemony War of the “AI Factory”: What is Microsoft’s Next-Generation Infrastructure Strategy?
In 2025, the main battlefield for AI development is shifting from “models” to “infrastructure.” Immediately after OpenAI announced a $1 trillion investment in its own data centers, Microsoft CEO Satya Nadella declared, “We already have an AI factory.” This statement symbolizes a new phase in the battle for cloud supremacy.
1. Microsoft’s “AI Factory” Concept
Nadella unveiled the first large-scale AI system Microsoft has brought online on X (formerly Twitter). He called it an “NVIDIA AI factory” and emphasized, “This is just the first one.”
This AI factory consists of over 4,600 NVIDIA GB300 rack computers, equipped with the latest Blackwell Ultra GPUs. NVIDIA’s ultra-high-speed networking technology, “InfiniBand,” is used for data transfer. Microsoft plans to deploy “hundreds of thousands of Blackwell GPUs” to data centers around the world in the future.
The foresight of NVIDIA CEO Jensen Huang in acquiring Mellanox for approximately $6.9 billion in 2019 was truly for this era.
2. Between “Collaboration and Competition” with OpenAI
The timing is also noteworthy. OpenAI recently signed large-scale data center contracts with both NVIDIA and AMD. CEO Sam Altman has stated, “We will build more AI data centers,” and is moving forward with investments totaling $1 trillion.
In response, Microsoft dares to assert: “We have already deployed over 300 data centers in 34 countries. We are prepared to meet the demand for cutting-edge AI.”
This statement contains a check against OpenAI’s move to build its own physical infrastructure.
In fact, the structure where OpenAI’s models run on Azure suggests a potential struggle for dominance, even while maintaining a co-existence between the two companies.
3. Next-Generation Infrastructure to Power “Frontier AI”
According to Microsoft, this AI system is capable of handling “models with hundreds of trillions of parameters.”
This statement indicates that super-large-scale models from GPT-5 onwards have reached a scale that cannot possibly be run on conventional data centers.
Through the expression “AI factory,” the company has presented a new concept of a “factory that produces models” rather than just a data center.
In other words, computing resources themselves are being recognized as “production equipment” that generates knowledge and value.
4. The Future of the AI Infrastructure War—To the Second Act of the “Cloud Three Kingdoms”
The tripartite relationship between Microsoft, OpenAI, and NVIDIA is complex, yet it forms the foundation of the AI economy.
OpenAI: The “brain” responsible for the intellectual production of models
NVIDIA: The “muscles” that supply GPUs and networks
Microsoft: The “skeleton” of cloud infrastructure that powers it
Within this trinity, whoever controls the “bottleneck” will determine the winner of the next decade.
While NVIDIA monopolizes chip supply, Microsoft is attempting to counter with “operational scale and reliability.”
At TechCrunch Disrupt, held at the end of this month (October 27–29), Microsoft CTO Kevin Scott is scheduled to discuss plans for handling AI workloads.
The moment the full picture of the AI factory is revealed, the power map of the cloud industry will likely be redrawn once again.
Conclusion
While OpenAI creates the “AI brains” that build the future, Microsoft is moving to secure the “foundation” for them.
Hegemony in the AI era depends on who possesses the most robust and efficient “computing factory.”
