An investment event is looming on the horizon that could rewrite the history of capital markets. On October 30, 2025, Reuters published exclusive information about potentially the largest investment opportunity thanks to an IPO in history. OpenAI, a pioneer in generative artificial intelligence and creator of ChatGPT, is preparing to go public, according to a growing number of reports.
Each of us could take advantage of this unique opportunity to invest in OpenAI and participate in the development of a company that is transforming the future. At the same time, however, it is necessary to take into account certain risks and unrealistic expectations and learn from history.
OpenAI Prior to Going Public
OpenAI was founded in 2015 as a non-profit research laboratory with the aim of ensuring that the development of artificial intelligence benefits all of humanity. Over time, however, it has transitioned to a hybrid model combining research with commercial activities. This made it attractive to investors who see its ability to generate profit thanks to ChatGPT, DALL·E, and API access to models. At the same time, however, OpenAI retained its status as a capped-profit entity, a unique legal structure combining ethical principles with business potential.
The question now occupying the markets is when OpenAI will go public. According to Reuters, it could be as early as the second half of 2026. However, other sources, such as the Times of India, report that the public offering will not take place until 2027. The company itself is vague about specific dates and emphasizes that its main goal is long-term stability, not the fastest possible IPO.
Meanwhile, the market is already preparing for this event. Many investors are excited by the idea that history will repeat itself with a dizzying IPO like Google’s. Those who invested in Google’s initial public offering in 2004 have seen a return of +13,164% over the past 21 years. In other words, if their original investment in shares was $1,000, in October 2025 their value will be $132,644.
OpenAI IPO Valuation
OpenAI’s valuation estimates are extraordinary. In the last investment round, the company was valued at approximately $300 billion, while other internal transactions show figures around $500 billion. According to speculative estimates by some analytical sources, the company’s value could be valued at up to $1 trillion when it goes public, making it one of the largest or largest IPOs in history. With such capitalization, OpenAI could surpass the current records held by tech giants such as Apple, Saudi Aramco, and Microsoft.
Such a high value is a double-edged sword for investors. On the one hand, it is a huge opportunity to participate in the growth of a company that is setting the direction for the entire industry. On the other hand, high valuations are often associated with the risk of unfulfilled expectations. Investors must realize that OpenAI operates in an extremely competitive environment alongside Anthropic, Google DeepMind, and Amazon. If revenue growth slows or research costs rise sharply, the value of the shares after the IPO could be highly volatile.
OpenAI Shares
In order for OpenAI to carry out its initial public offering, it must meet a number of regulatory, financial, and technical requirements. Before going public, it will be necessary to publish a detailed prospectus for investors, which will describe the company’s financial results, risks, ownership structure, and strategic goals in detail. OpenAI will have to go through the approval process with the US Securities and Exchange Commission (SEC), prepare audited financial statements, and set up transparent reporting. It will also be important to clearly define its relationship with Microsoft, which is its main strategic partner and investor, as the market will want to know the extent of their cooperation and dependence.
Although OpenAI was only founded in 2015, its growth and influence on the technology sector are extraordinary. In less than a decade, it has achieved market power and technological impact that other companies have taken generations to achieve. In many ways, the OpenAI start-up has surpassed even Elon Musk’s projects, including SpaceX, in terms of speed of commercialization, global product expansion, and the ability to turn revolutionary technology into a commonly used service. The question remains whether this momentum will hold up in the public market, which tends to be relentlessly critical of young companies.
There are high expectations for OpenAI’s share price, not only in terms of long-term investment, but also immediately after the IPO. By way of comparison, after Microsoft’s IPO in 1986, the company’s share price rose from $21 to $35.5 in a single day. This represented a share price increase of approximately +69.05%.
A Bright Future With OpenAI
Going public would primarily provide OpenAI with a new source of capital, enabling further expansion and technological development. The company could finance the construction of data centers, improve its models, and expand its services to other sectors, such as healthcare, education, and industry. At the same time, it would increase financial transparency, which could strengthen the confidence of investors and partners. An IPO would also bring liquidity to existing investors and employees who hold stock options, allowing them to realize the value of their holdings.
Whether the IPO takes place next year or the year after, one thing is certain: it will be a key event in modern finance. Investing in OpenAI will be associated with high potential returns, but also with significant risks. For experienced investors who follow tech trends and can assess the long-term impact of AI on the economy, OpenAI’s entry into the stock market could be an opportunity unlike anything the stock market has ever seen.
