OpenAI Is About to Go Public — Here's What That Means If You Use ChatGPT

OpenAI is about to do something no AI company has done before: go public on the stock market with a valuation that could hit one trillion dollars.

The company behind ChatGPT is preparing to file its IPO paperwork with the SEC as early as this week. Goldman Sachs and Morgan Stanley are advising on what would be one of the largest tech IPOs in history. The target is a September 2026 debut.

To put that trillion-dollar number in context, Apple took 42 years to reach a trillion-dollar valuation. Google took 21 years. OpenAI could get there in under four years since ChatGPT launched. That is how fast the AI market has moved.

The numbers behind the filing tell an incredible growth story. OpenAI hit $20 billion in annualized revenue by the end of 2025 and has surpassed $25 billion as of early 2026. ChatGPT now has more than 900 million weekly active users. The company recently closed a $122 billion funding round at an $852 billion valuation — the largest private funding round ever.

But here is the part that gets less attention: OpenAI expects to lose $14 billion in 2026 alone. The company does not expect to turn a profit until roughly 2030. Running AI models at this scale is breathtakingly expensive, with billions going to data centers, chips, and raw computing power every year.

So why go public now? Two big reasons. First, OpenAI needs money — a lot of it. The company has committed to spending around $600 billion over the next five years on infrastructure. Private funding, even at record levels, can only stretch so far. Public markets unlock a much larger pool of capital.

Second, the legal path just cleared. A California jury dismissed Elon Musk's $150 billion lawsuit against OpenAI last week, removing the biggest legal cloud hanging over the company. That verdict was widely seen as the final hurdle before an IPO could move forward.

If you use ChatGPT — and statistically, there is a decent chance you do — the IPO will not change your experience overnight. But it will change the company's incentives in ways that trickle down to your daily use.

Public companies answer to shareholders, and shareholders want growth. That pressure has already started showing up. OpenAI introduced a cheaper $8 per month plan to grow its subscriber base from 47 million paid users toward a target of 122 million by year-end. It launched ads inside the free version of ChatGPT earlier this year. Expect more of both.

The bigger shift is strategic. OpenAI's CEO Sam Altman has said ChatGPT needs to become a productivity tool, not just a chatbot. That means deeper integrations with business software, more enterprise features, and more reasons for companies to pay premium prices. The casual, free-tier experience that introduced most people to AI may slowly become the loss leader rather than the main event.

It is also worth watching what an IPO means for competition. OpenAI is not the only AI company heading for public markets. Anthropic, maker of Claude, is targeting an October 2026 listing at around $900 billion. SpaceX just filed its own prospectus. The second half of 2026 is shaping up to be the biggest stretch of tech IPOs since the dot-com era.

For small business owners, this wave of IPOs means more money flooding into AI development, more tools hitting the market, and more aggressive pricing wars. That is mostly good news if you are a buyer of AI tools rather than a builder of them.

The risk, as always with IPOs, is that public market pressure pushes companies toward short-term revenue over long-term quality. When shareholders demand quarterly growth, features get paywalled, free tiers get squeezed, and the product starts optimizing for engagement rather than usefulness. We have seen this playbook before with social media. AI does not have to follow the same path, but the incentive structure is familiar.

There is also the question of what OpenAI's financial disclosures will reveal. The S-1 filing will be the first time the public sees detailed revenue breakdowns, cost structures, and risk factors. We will finally learn exactly how much it costs to run ChatGPT, how dependent the company is on Microsoft, and what OpenAI considers its biggest threats. That transparency is one of the genuine benefits of going public.

The grounded takeaway: the company that made AI mainstream is about to become a publicly traded company. If you use ChatGPT for work, creativity, or just curiosity, nothing changes tomorrow. But the incentives driving the product are about to shift from impress investors to raise the next round to impress Wall Street every quarter. That is a different kind of pressure, and it will shape what ChatGPT becomes over the next few years. Pay attention to the S-1 when it drops — it will tell you more about the future of AI than any product demo.
