OpenAI has grown to $840 billion: the developer of ChatGPT raised $110 billion through investments from Amazon, Nvidia and SoftBank.

Large investment round for OpenAI: $110 billion and company valuation of $840 billion

OpenAI completed the largest investment round in its history, raising $110 billion, which allowed it to reach a market valuation of $840 billion. Competitor Anthropic also actively raised funds this year to cover expenses for chips and data centers for artificial intelligence. Both players regularly collaborate with the same group of venture funds and large technology companies.

After receiving these funds, OpenAI is valued at $840 million, with an expected maximum of $850 million. The company remains open to bringing in additional investors as the round concludes.

What was Amazon’s contribution?
Amazon invested $50 billion, strengthening its strategic ties with OpenAI:

* Use of Trainium chips – Amazon’s own line of AI chips will be used in OpenAI projects.
* Joint development of specialized models for Amazon engineering teams.
* Payment commitments: OpenAI plans to spend $100 million on AWS services over the next eight years. Earlier, in November 2025, the company announced a contract worth $38 million over seven years.

Sam Altman, CEO of OpenAI, emphasized: “Amazon can give us enormous potential for new demand and opportunities in the market.” Amazon’s CEO Andy Jassy described the deal as a long‑term profit for the company. Microsoft, the former exclusive infrastructure partner, confirmed that its relationship remains unchanged: “Nothing in today’s announcements changes the terms of cooperation between Microsoft and OpenAI.”

Anthropic situation
Anthropic also actively raised funds: at the beginning of the month the company received $30 million from investors, including Nvidia and Microsoft. Thanks to these investments, its market valuation was increased to $380 million.

What does this mean for the AI market?
Funding for OpenAI and Anthropic demonstrates a “cyclical” financing model: leading AI companies collaborate with chip suppliers and cloud service providers. This satisfies the sector’s huge infrastructure needs, but there is a risk that excess demand could lead to losses if actual performance fails to meet inflated expectations.

Altman tried to dispel concerns about an “AI bubble”: “I understand where the concerns come from. It only makes sense if new revenues flow into the AI ecosystem.” He emphasized that his efforts are focused on increasing computing power to support ChatGPT and other OpenAI products.

Key takeaways

1. OpenAI raised $110 billion, company valuation of $840 million.
2. Amazon invests $50 million, strengthening collaboration through Trainium chips and AWS services.
3. Anthropic received $30 million, valuation rose to $380 million.
4. Partnerships with technology giants provide infrastructure but carry the risk of overinvestment when demand is low.
