Microsoft and OpenAI officially end seven-year exclusive cooperation: freedom of cloud choice, end of revenue sharing, and reshaping of the AI ​​competition landscape

Core conclusion

On April 27, 2026, Microsoft and OpenAI officially announced the end of the exclusive cooperation and revenue sharing agreement, ending the seven-year in-depth binding relationship since 2019. This change means:

• OpenAI will no longer exclusively own the Azure cloud and can freely use infrastructure such as AWS and Google Cloud
• Microsoft will no longer collect revenue share from OpenAI and will no longer pay model licensing fees to OpenAI
• Model and IP licensing changed from exclusive to non-exclusive, Microsoft can freely integrate Anthropic Claude, Google Gemini and other competing products
• Microsoft's stake in OpenAI has dropped from 49% to approximately 27%, significantly weakening its control

For AI money-making practitioners, this means that competition in the AI model market will become more intense, API prices are expected to be further reduced, and it also means that more cloud platforms are available - you can choose the most cost-effective inference infrastructure on demand.

Key Points

• Time of incident: April 27, 2026
• Affected objects: All developers, AI content producers, and SaaS entrepreneurs who use AI API to build products
• Core changes: Microsoft and OpenAI have shifted from "deep binding" to "flexible cooperation", and the AI industry has entered a new competitive landscape.

Background and trigger events

The cooperation between Microsoft and OpenAI began in 2019, when Microsoft invested US$1 billion in OpenAI and obtained exclusive cloud service rights and revenue sharing. Since then, Microsoft has continued to invest more (a total of more than 13 billion US dollars), and its shareholding was once as high as 49%. During these seven years, OpenAI's models could only run on the Azure cloud, and Microsoft received a profit share of all OpenAI's revenue.

This exclusive cooperation pattern will gradually loosen from 2024 to 2026. With the rise of Anthropic Claude, the continuous iteration of Google Gemini, and the impact of DeepSeek V4 on the market at extremely low prices, both Microsoft and OpenAI are facing their own pressures. Microsoft hopes to integrate competing products such as Claude into products such as Office and GitHub Copilot, while OpenAI needs freer cloud choices and stronger financing capabilities.

Adaptation suggestions

In response to this industry change, AI content producers and independent developers can:

1. Switch inference provider — OpenAI API no longer has to go to Azure. You can compare the pricing and performance of AWS Bedrock and Google Cloud Vertex AI to choose the provider that best suits your scenario.
2. Embrace a multi-cloud strategy — The inference costs of different models on different clouds may vary greatly, so establish a flexible routing mechanism
3. Focus on low-cost alternatives such as DeepSeek V4 — If the current workflow relies on batch inference of large models, test a hybrid strategy in which the open source model does 80% of routine tasks and the high-end model does 20% of critical tasks.
4. Learn the ecology of multiple AI tools — Microsoft Office will integrate Claude, GitHub Copilot may integrate multiple models, and the risk of relying on a single tool increases

Task List

• Compare currently used AI API pricing (OpenAI vs Claude vs DeepSeek V4)
• Evaluate whether you need to test your deployment on AWS Bedrock or GCP
• Establish multi-model evaluation benchmarks to avoid single vendor lock-in
• Pay attention to the details of Bedrock+OpenAI at the AWS San Francisco event tomorrow
