OpenAI Confidentially Files for IPO with Valuation Exceeding $850 Billion

OpenAI has officially announced the filing of a confidential S-1 form for a public offering on the American market. This is one of the most anticipated technology IPOs in history, one that could potentially reshape the entire AI landscape and attract the attention of global investors.

Valuation Exceeding $850 Billion

The company's expected valuation will exceed $850 billion, making the offering one of the largest ever in the history of public markets. For context: this valuation exceeds Amazon's current market capitalization and is comparable to Microsoft's. This impressive figure reflects OpenAI's rapid growth over recent years and enormous global demand for AI solutions.

ChatGPT, the company's flagship product, remains the most popular application in history in terms of user acquisition speed. Within months, it reached 100 million active users, something no application had achieved before. This impressive metric forms the basis of investor valuation and demonstrates the scale of the company's impact on the global market.

The company has already attracted massive amounts of venture capital in previous funding rounds, including investments from Microsoft, Khosla Ventures, and other top-tier funds. The IPO will allow it to reach an entirely new level of market capitalization and liquidity.

Timelines Remain Open

An interesting and atypical detail: OpenAI directly stated that it is not in a hurry with the IPO and timelines could be pushed back indefinitely. The company emphasized that there are a number of tasks and features that are much easier to implement as a private company than with public reporting requirements.

"We have not determined a timeline; this could take some time, because there are things that we find easier to do as a private company.

But these are complex tradeoffs, and it gives us the option to go public sooner if that turns out to be better," the company said in an official statement.

This is atypical communication for a giant company preparing for an IPO. Usually, such announcements are accompanied by specific timelines and financial targets. Here, however, management honestly acknowledges: going public is not a simple choice with multiple pros and cons that need to be carefully weighed. Such candor and even humor in the rhetoric came as a surprise to Wall Street, which is accustomed to far more cautious and formal communication from mega-cap companies.

Why Announce Now

The decision to publicly announce the confidential S-1 filing has several strategic reasons:

• Proactive news management—preventing speculation and information leaks about the filing, which are inevitable in such a large-scale deal.
• Narrative control—establishing their version of events before IPO details emerge in financial media.
• Demonstrating confidence to investors and partners—showing that the company is ready for public status and managing shareholder interests.
• Regulatory transparency—signaling to the SEC and other authorities the seriousness of intentions and readiness to comply with all requirements.

Scale and Historical Context

For comparison, in recent years the largest tech IPOs included Alibaba ($25 billion valuation in 2014), Saudi Aramco ($1.7 trillion in 2019), and other major offerings. OpenAI's $850 billion valuation puts it in an entirely different league, approaching the market capitalization of entire nations. This reflects the weight of AI technologies in the modern economy and the investment appetite of funds amid the AI boom.

What This Means for the IPO Industry

OpenAI will be a turning point not only for the company itself but for the entire AI sector as a whole. The public offering will attract enormous capital for the development of frontier AI systems, but at the same time will increase pressure on regulators to find a balance between innovation and responsibility. Investors will want to see not only technological breakthroughs but also a real path to profitability.
