OpenAI has secured $110 billion in private investment, the firm declared Friday morning, marking the beginning of one of the most substantial private funding rounds ever recorded. This latest funding includes a $50 billion contribution from Amazon, alongside $30 billion each from Nvidia and SoftBank, based on a pre-money valuation of $730 billion.

Importantly, the funding round remains open, and OpenAI anticipates additional investors will come on board as it advances.

“We are entering a new era where frontier AI transitions from research into regular application on a global scale,” OpenAI stated. “Leadership will hinge on who can expand infrastructure rapidly enough to meet demand and convert that capacity into products that people depend on.”

As part of the investment, OpenAI is establishing major infrastructure collaborations with both Amazon and Nvidia. Similar to previous funding rounds, it’s probable that a considerable part of the funding will be in the form of services rather than actual cash, although the exact division was not revealed.

The company’s last funding round concluded in March 2025, securing $40 billion against a $300 billion valuation. At that time, it was the largest private funding round recorded.

In its collaboration with Amazon, OpenAI aims to create a new “stateful runtime environment” where OpenAI models will operate on Amazon’s Bedrock platform. The company will also enhance its previously announced AWS partnership, which pledged $38 billion in computing services, by an additional $100 billion. OpenAI has promised to utilize a minimum of 2GW of AWS Tranium computing as part of this agreement and also plans to develop custom models to aid Amazon’s consumer products.

“We have numerous developers and companies excited to operate services powered by OpenAI models on AWS,” remarked Amazon CEO Andy Jassy in a statement, “and our exceptional partnership with OpenAI to deliver stateful runtime environments will revolutionize possibilities for customers creating AI applications and agents.”

The Information previously indicated that $35 billion of Amazon’s investment might depend on the company achieving AGI or conducting its IPO before year’s end. OpenAI’s announcement clarifies the funding distribution but states only that the extra $35 billion will be provided “in the coming months when certain conditions are fulfilled.”

OpenAI provided limited information regarding the Nvidia partnership but mentioned a commitment to utilizing “3GW of dedicated inference capability and 2GW of training on Vera Rubin systems” as part of the agreement.

Nvidia’s involvement in this funding round has been widely speculated, especially as rumors of a $100 billion investment in September transitioned to reports of a lower investment in the subsequent months.

In January, Huang rejected the notion that Nvidia was retreating from OpenAI, asserting, “we will invest a significant amount of money. I have faith in OpenAI. The work they are doing is remarkable.”
