OpenAI has attracted plenty of attention as a leading artificial intelligence (AI) company, driving innovation and shaping the future of this exciting technology. Its products and services like ChatGPT have become household names, and you might be wondering if it’s possible to invest in OpenAi and buy shares.
Unfortunately, OpenAI shares are not yet publicly traded or listed on a stock exchange. In this guide, we’ll explore the basics of OpenAI, the prospects of an OpenAI IPO, and alternative ways to invest and gain exposure.
Once OpenAI goes public, you'll need a brokerage account to invest. Consider opening a brokerage account today so you're ready as soon as the stock hits the market.
October 6, 2025: OpenAI and AMD announced a "strategic partnership" that will see OpenAI deploy 6 gigawatts of AMD Instinct GPUs over a number of years. Tied into the deal, OpenAI gets options for 160m AMD shares (vesting in line with GPU deployments), meaning Open AI will likely become a major stakeholder in AMD.
OpenAI is a leading research organisation and technology stock focused on developing AI solutions. Founded in 2015 by notable figures such as Sam Altman, OpenAI’s mission is to ensure that AI serves as a force for good. Its groundbreaking products include large language models (LLMs) like GPT (Generative Pre-trained Transformer) and applications like the beloved and hated ChatGPT, which is already transforming industries from customer service to education.
We recently got news that OpenAI is preparing plans to file its paperwork for an IPO in 2026, with roughly a $1 trillion valuation, and hoping to raise about $60 billion.
According to Reuters, we could see OpenAI’s IPO take place in late 2026 or early 2027. There’s not been an official statement from OpenAI just yet, so we’ll have to see how this unfolds throughout 2026.
Currently, the estimated valuation of OpenAI is a whopping $157 billion (around £126 billion). This valuation was pinned to this hot AI stock after it raised $6.6 billion (about £5 billion) in its latest round of funding (which is when Nvidia and SoftBank got involved).
Currently, there is no fixed date for OpenAI’s IPO. Keep an eye on the news and our IPO calendar for the latest announcements from OpenAI relating to the stock going public. IPOs can take time to prepare, often years, and OpenAI may need more time to mature and develop before reaching this stage.

Be mindful that although there’s plenty of excitement around AI and AI-related technology, this sector is still in its infancy and we’re yet to see any major impacts these companies are going to have, most of the hype is still around its potential.
All investing should be regarded as longer term. The value of your investments can go up and down, and you may get back less than you invest. Past performance is no guarantee of future results. If you’re not sure which investments are right for you, please seek out a financial adviser. Capital at risk.
