OpenAI is gearing up for an initial public offering (IPO) that could make it one of the world's most valuable companies, with plans to reserve shares for retail investors. The artificial intelligence company behind ChatGPT has crossed $25 billion in annualized recurring revenue, less than four years after launching the chatbot that sparked the modern AI conversation. While you cannot yet buy OpenAI shares directly, the company's Chief Financial Officer Sarah Friar recently signaled that retail investors will have opportunities to participate when the IPO timeline is disclosed .

Why Is OpenAI's IPO Such a Big Deal?

OpenAI's trajectory has been extraordinary. ChatGPT became the fastest platform ever to reach 100 million monthly active users, accomplishing this milestone in roughly two months after its November 2022 launch. By February 2026, the company announced that ChatGPT had surpassed 900 million weekly active users . This explosive growth has attracted billions of dollars in venture capital and positioned OpenAI to command a valuation above $1 trillion when it becomes publicly traded, according to industry projections.

The company's partnerships with major technology firms provide a strong foundation for continued growth. Oracle Corporation has deployed OpenAI's GPT-5 across its database portfolio, Amazon Web Services (AWS) is enabling organizations to build and manage AI agents using OpenAI models, and Nvidia plans to invest $100 billion in OpenAI as part of an "AI factory" initiative deploying 10 gigawatts of computing power using Nvidia's Vera Rubin chips . Microsoft remains OpenAI's most significant partner, though the exclusivity of their relationship has weakened in early 2026.

How Can Retail Investors Gain Exposure to OpenAI Before the IPO?

Since OpenAI shares are not yet publicly available, investors seeking exposure to the company's growth must look to indirect opportunities. According to M&A consultancy experts, the most practical approach involves investing in companies that benefit from the broader AI buildout rather than trying to purchase OpenAI directly.

Dustin Engel, U.S. director at WY Partners, explained the strategy: "If investors want exposure, it is typically indirect, through public companies tied to the AI buildout, such as semiconductors, cloud infrastructure and enterprise software. If someone says they want to invest in ChatGPT, the more useful framing is that they want to invest in the AI buildout" .

This approach opens up a wider range of investment opportunities across multiple sectors and company sizes. Smaller companies that are well positioned for the AI boom may offer higher long-term returns than the trillion-dollar tech giants, though they come with greater risk .

Steps to Evaluate AI-Exposed Investment Opportunities

• Assess Partnership Depth: Look for companies with direct, exclusive, or deeply integrated partnerships with OpenAI or similar AI leaders, as these relationships tend to drive sustained revenue growth and competitive advantages.
• Evaluate Infrastructure Exposure: Consider companies providing the underlying infrastructure for AI, including semiconductor manufacturers, cloud service providers, and data center operators, as these benefit regardless of which AI model dominates.
• Review AI Product Integration: Examine how thoroughly a company has integrated AI tools into its core business offerings, as companies with broad AI adoption across multiple product lines tend to capture more value from the AI buildout.

Which Companies Offer the Strongest OpenAI Exposure?

Several major publicly traded companies have significant relationships with OpenAI and stand to benefit from its growth. Microsoft is one of the most direct plays, having extended its partnership with OpenAI in early 2023 through a multiyear, multibillion-dollar investment. The deal made Azure OpenAI's exclusive cloud provider for stateless APIs, though OpenAI has since diversified to work with other cloud providers. Microsoft released a joint statement in February affirming that the partnership "remains strong and central," with "unchanged" commercial and revenue shares .

Beyond its OpenAI relationship, Microsoft has developed its own AI initiatives. The company unveiled Copilot, an AI assistant that helps users create images, produce documents, and complete presentations. Microsoft Copilot for Security has been particularly successful, with 70 percent of Fortune 500 companies adopting the technology .

Alphabet represents another compelling opportunity. While the company is one of OpenAI's cloud providers, its AI exposure extends far beyond that single relationship. Google uses artificial intelligence to optimize search results, and the company launched Gemini, a natural language processing tool that competes directly with ChatGPT. Alphabet also owns more than 10 percent of Anthropic, a key ChatGPT competitor. Google Cloud now represents about 16 percent of Alphabet's total revenue and has benefited substantially from AI tailwinds .

Nvidia has become the world's most valuable publicly traded company, briefly touching a $5 trillion valuation near the end of 2025. The semiconductor manufacturer produces the graphics processing units (GPUs) that power AI model training and inference, and OpenAI cannot fulfill rising demand for ChatGPT without Nvidia's chips. The company generated $215.9 billion in fiscal 2026 revenue, up 65 percent year over year, and CEO Jensen Huang has predicted the company will generate $1 trillion in data center revenue .

Oracle has also positioned itself as a key infrastructure partner, with deep integration of GPT-5 into its autonomous database offerings. Additionally, IREN Ltd., an AI data center provider, secured a $9.7 billion contract with Microsoft for 200 megawatts of capacity, demonstrating how infrastructure companies benefit from OpenAI's expansion .

The IPO timeline remains uncertain, but OpenAI's announcement that it will reserve shares for retail investors signals a shift toward broader public participation in one of the most significant technology companies of the era. Investors interested in gaining exposure before the public offering have multiple pathways through established technology companies with proven AI partnerships and infrastructure advantages.
