Microsoft Spends More Than $100 Billion on OpenAI Partnership

Microsoft has spent more than $100 billion on its partnership with OpenAI, according to a report. The sum reflects the software maker's substantial financial commitment to the artificial intelligence company and its development. The investment has supported OpenAI's growth over multiple years.

Microsoft provides both capital and cloud computing infrastructure that the AI company uses to train and run its models. The partnership dates back to 2019 and has expanded through several rounds of funding and technical collaboration. The scale of the spending underscores how important the relationship has become for both organizations.

OpenAI has developed widely used tools including ChatGPT while Microsoft has integrated the technology across its own products and services.

The companies first announced their collaboration in 2019.

Microsoft began by investing $1 billion and later increased its commitments in subsequent years. The total outlay has now surpassed $100 billion. The partnership gives Microsoft exclusive rights to commercialize OpenAI's technology through its Azure cloud platform. OpenAI in turn gains access to massive computing resources required for large-scale AI model training.

Both companies continue to operate under the existing agreement.

The partnership remains active as of May 2026 with no announced changes to its structure. Microsoft has described the relationship as central to its artificial intelligence strategy.
