On June 9, OpenAI quietly filed confidential paperwork with the U.S. Securities and Exchange Commission to go public. Minutes later, it publicly confirmed the filing.
That might sound like a routine corporate announcement, but it marks one of the biggest moments in technology and investing this decade.
The company behind ChatGPT is preparing for what could become the largest technology IPO since the dot-com era. And if analyst estimates are right, OpenAI could debut with a valuation above $1 trillion.
That number alone is enough to grab headlines.
But once you look beyond the excitement, the OpenAI story becomes far more complex than a simple “AI company goes public” narrative.
The Headline Number Is Massive
OpenAI’s most recent funding round in March 2026 valued the company at $852 billion.
That round raised $122 billion, making it the largest private funding round ever completed.
Now, many analysts expect the IPO valuation to cross $1 trillion.
To put that into perspective:
- Alibaba’s famous 2014 IPO was valued at roughly $230 billion
- OpenAI’s expected valuation is more than four times larger
- It would instantly become one of the most valuable companies in the world
The underwriters include Goldman Sachs and Morgan Stanley, signaling that Wall Street is taking this listing extremely seriously.
The Growth Story Is Incredible
If investors are willing to entertain a trillion-dollar valuation, it’s because OpenAI’s growth has been extraordinary.
Just a few years ago, OpenAI generated around $2 billion in annualized revenue.
By early 2026, it was reportedly generating close to $2 billion every month.
That’s one of the fastest revenue ramps ever seen in technology.
The company’s flagship product, ChatGPT, now serves more than 900 million weekly active users worldwide.
Think about that for a second.
Very few consumer products in history have reached that level of global adoption so quickly.
The bull case is easy to understand:
- Massive user base
- Strong enterprise adoption
- Global brand recognition
- AI becoming part of everyday workflows
- Potential to become a productivity platform rather than just a chatbot
For believers, this is just the beginning.
But There’s A Problem Investors Can’t Ignore
Despite all the growth, OpenAI still isn’t profitable.
In fact, the company is expected to lose around $14 billion in 2026 alone.
That sounds shocking for a company approaching a trillion-dollar valuation.
The reason comes down to one word:
Compute.
Running advanced AI models requires enormous amounts of infrastructure.
Every question users ask ChatGPT costs money.
Every image generated costs money.
Every enterprise customer running AI workloads costs money.
Unlike traditional software businesses, serving more users isn’t close to free.
It’s actually expensive.
AI Economics Are Different From Traditional Software
For decades, investors loved software companies because of their economics.
Once the product was built, adding new customers cost very little.
That’s why businesses like Google, Salesforce, and many SaaS companies achieved strong margins as they scaled.
OpenAI faces a different reality.
Its estimated gross margin is around 33%.
For comparison:
- Salesforce entered public markets with gross margins around 73%
- Google was around 56%
- Snowflake was above 60%
OpenAI’s margin profile currently looks more like an infrastructure or semiconductor company than a traditional software company.
That doesn’t mean the business won’t succeed.
It simply means investors must believe that future technology improvements will make AI much cheaper to run.
That’s a prediction, not a guarantee.
The Company Structure Is Unlike Anything Wall Street Has Seen
One of the least understood parts of OpenAI is its corporate structure.
Most public companies have a straightforward setup:
Shareholders own the company and elect directors.
OpenAI is different.
Following its restructuring, OpenAI operates as a Public Benefit Corporation while a nonprofit foundation retains control of the board.
In simple terms:
- Investors can own shares
- Investors benefit from growth
- Investors do not fully control governance
The nonprofit foundation maintains significant influence over major decisions.
That creates an unusual situation.
Public investors may provide capital, but mission-related priorities could sometimes outweigh pure profit maximization.
Wall Street has never had to value a company of this size with a governance structure like this.
The IPO filing will need to clearly explain what rights shareholders actually receive.
Competition Is Getting Stronger
Another challenge is that OpenAI is no longer competing in an empty field.
A few years ago, ChatGPT dominated public attention.
Today, the landscape looks different.
Major competitors include:
- Google Gemini
- Anthropic
- Meta
- Elon Musk’s Grok
Recent market share data suggests ChatGPT’s dominance has declined as rivals have improved rapidly.
The AI race is no longer about one company leading comfortably.
It’s becoming a battle among several well-funded giants.
That matters because trillion-dollar valuations assume OpenAI remains a major winner.
If competition compresses pricing power or slows growth, investors may start asking tougher questions.
Three Things Investors Should Watch
When OpenAI’s IPO filing becomes public, three areas deserve special attention.
1. The Microsoft Relationship
Microsoft has been OpenAI’s most important partner.
Investors will want clarity on:
- Revenue-sharing arrangements
- Cloud infrastructure costs
- Licensing agreements
- Long-term dependency risks
The deeper the dependency, the more investors may worry about concentration risk.
2. Gross Margins
This may be the single most important financial metric.
Can OpenAI improve margins over time?
Investors will look for evidence that:
- AI models are becoming more efficient
- Cost per query is falling
- Infrastructure spending is becoming more productive
If margins improve significantly, the valuation becomes easier to justify.
If they don’t, questions will intensify.
3. Governance Rights
The IPO documents should clarify:
- Board control
- Voting rights
- Foundation authority
- Shareholder protections
This section could become one of the most closely read parts of the entire filing.
So Why Go Public Now?
The simplest answer is capital.
Building frontier AI is incredibly expensive.
OpenAI is projected to burn enormous amounts of cash over the next several years while building infrastructure, training models, and expanding globally.
Private investors have already provided hundreds of billions of dollars.
Public markets offer access to an even larger pool of capital.
And right now, investor enthusiasm around AI remains extremely strong.
OpenAI appears to be taking advantage of that window.
The Bottom Line
OpenAI’s IPO may become one of the most important public listings in technology history.
The company has:
- Extraordinary growth
- Massive user adoption
- A powerful global brand
- Ambitious long-term plans
But it also faces challenges that public investors cannot ignore:
- Heavy losses
- High infrastructure costs
- Rising competition
- An unconventional governance structure
The real debate isn’t whether OpenAI has changed the world.
It already has.
The real question is whether public markets are willing to assign a trillion-dollar valuation to a company that is still years away from profitability and operating under a structure unlike anything investors have seen before.
That tension between incredible opportunity and difficult economics is what will make this IPO one of the most closely watched market events of the decade.
