OpenAI confirmed its $110 billion valuation on Thursday, raising hopes that if it goes public it could become the largest IPO in U.S. technology history.
The company has not yet filed for an IPO. However, the valuation announced on February 27th places OpenAI ahead of some of Silicon Valley’s groundbreaking debutants, indicating strong support from major technology investors.
Which big tech companies are going all-in on OpenAI?
OpenAI has raised billions of dollars in private funding over the past few years. Its most important backer remains Microsoft, which has reportedly made multi-year investments totaling about $13 billion through structured equity and cloud partnerships.
The new funding includes $30 billion from SoftBank, $30 billion from NVIDIA, and $50 billion from Amazon. Additional financial investors are expected to participate as the round progresses.
Other major investors include Thrive Capital, Khosla Ventures, Sequoia Capital, and Andreessen Horowitz. These companies participated in early funding rounds as OpenAI expanded ChatGPT and enterprise AI infrastructure.
OpenAI could become the largest IPO in U.S. history
If OpenAI proceeds at this valuation, it would be one of the largest U.S. tech IPOs in history. The size of this fundraising is well below most historical IPO valuations.
For comparison, Meta Platform (Facebook) went public in 2012 for about $104 billion. Snowflake debuted in 2020 with about $70 billion. Alibaba Group went public in 2014 for about $168 billion.
Globally, Saudi Aramco still holds the overall IPO record with $1.7 trillion.
OpenAI is valued at $730 billion and is now in a different category.
If the company goes public, it would likely rank among the largest tech IPOs in U.S. history, reflecting the level of confidence investors have in Frontier AI.
The company has not disclosed a potential listing date or price range. These details will be revealed in the official IPO filing.
