Amazon and NVIDIA simultaneously fund OpenAI, with an IPO valuation reaching 730 billion

OpenAI announced the completion of a new funding round on February 27, 2026, with a pre-money valuation of $730 billion. The round raised $110 billion, led by Amazon ($50 billion), SoftBank, and NVIDIA (each $30 billion). If the company proceeds with an IPO, this valuation could set a new record for the largest U.S. tech company listing.

Funding Lineup: Tech Giants Making a Full Bet

Microsoft remains OpenAI’s most important long-term supporter, committing to invest approximately $13 billion over several years through structured equity and cloud collaboration. The three main investors in this round—Amazon ($50 billion), SoftBank ($30 billion), and NVIDIA ($30 billion)—represent three key areas: cloud infrastructure, tech investments, and AI computing chips.

NVIDIA, as the world’s leading AI training chip supplier, has made a significant bet on OpenAI, strengthening their strategic partnership in AI infrastructure. Amazon, through Amazon Web Services (AWS), continues to expand its AI cloud business, and this investment further deepens their integration in AI workloads.

Other major investors include Thrive Capital, Khosla Ventures, Sequoia Capital, and Andreessen Horowitz, all of which participated in early funding rounds and continue to support the expansion of ChatGPT and enterprise AI infrastructure.

Historical IPO Valuation Milestone: Surpassing Meta by Seven Times

From a historical perspective, OpenAI’s current valuation of $730 billion far exceeds the valuation of nearly all U.S. tech companies at their IPOs.

Major Tech IPO Valuations in History

• Meta Platforms (Facebook) 2012: IPO valuation around $104 billion
• Alibaba Group 2014: IPO valuation around $168 billion (U.S. listing)
• Snowflake 2020: IPO valuation around $70 billion
• Saudi Aramco: Holds the record for total global IPO funding at $1.7 trillion

OpenAI’s current valuation: $730 billion, second only to Saudi Aramco globally.

In the U.S. market, if OpenAI were to go public at this valuation, it would far surpass Alibaba’s approximately $168 billion, becoming the largest single IPO in U.S. tech history. It’s important to note that OpenAI has not yet filed for an IPO; details such as the listing date, share price range, and issuance structure will be confirmed when the official IPO documents are released.

Frequently Asked Questions

Is OpenAI definitely going public now, and when is the IPO expected?

As of February 27, 2026, OpenAI has not filed for an IPO nor announced a specific listing date or share price range. The funding round confirms a pre-money valuation of $730 billion, which has increased market expectations for an IPO, but an official plan has yet to be announced.

Why are Amazon and NVIDIA making large investments in OpenAI at this time?

Amazon, through AWS, is expanding its AI cloud infrastructure, and investing in OpenAI helps deepen their collaboration on AI workloads and strengthen AWS’s position in the enterprise AI market. NVIDIA, as a primary supplier of AI training chips, is further consolidating its strategic position within the OpenAI ecosystem through capital investment, creating a dual binding of supply chain and capital.

How big is the gap between OpenAI’s $730 billion valuation and the historical U.S. tech IPOs?

The gap is quite significant. Meta’s IPO in 2012 was valued at about $104 billion, and Alibaba’s in 2014 at about $168 billion—both milestones. OpenAI’s current valuation is over 7 times that of Meta and more than 4 times that of Alibaba. If it successfully goes public, it will rewrite the history of U.S. tech IPO valuations.
