How to Buy OpenAI Stock Before the IPO

OpenAI just hit a $500 billion valuation—making it the most valuable private company in history. The creator of ChatGPT, GPT-4, and DALL-E has captured the world’s imagination, and you want in before it goes public.

The short answer: retail investors cannot buy OpenAI stock. The company remains private, has no announced IPO timeline, and the secondary markets that trade OpenAI shares require accredited investor status plus $25,000-$100,000 minimums. Even then, availability is extremely limited with waitlists stretching six months or longer.

But there’s a significant consolation prize. Microsoft has invested over $13 billion in OpenAI and holds exclusive licensing rights to its models. If you want OpenAI exposure, you might already have it through one of the world’s largest public companies.

This guide breaks down exactly who can access OpenAI shares, through which platforms, at what cost—and why Microsoft might be the smarter play anyway.

Quick Summary

What Is OpenAI?

OpenAI is the artificial intelligence research company behind ChatGPT, the fastest-growing consumer application in history. Founded in December 2015 as a nonprofit AI research lab, the company has evolved into the dominant force in generative AI.

Key Products

ChatGPT revolutionized how people interact with AI. Launched in November 2022, it reached 100 million users faster than any application before it. The platform now serves over 100 million weekly active users and has become the default interface for AI assistance.

GPT-4 and its successors power not just ChatGPT but thousands of enterprise applications through OpenAI’s API. Businesses pay for access to these models, generating an estimated $12 billion in annualized revenue.

DALL-E 3 generates images from text descriptions, while Sora (video generation) and Whisper (speech recognition) round out OpenAI’s product suite.

The Microsoft Partnership

Microsoft’s relationship with OpenAI goes beyond a typical investment. The tech giant has committed over $13 billion across multiple funding rounds since 2019. In return, Microsoft received:

• Exclusive licensing rights to OpenAI’s models for commercial products
• Azure OpenAI Service integration, bringing GPT to enterprise customers
• Revenue sharing from OpenAI’s commercial success
• Significant economic interest in the company’s future

This partnership means Microsoft shareholders already have substantial exposure to OpenAI’s success—a point we’ll return to in the alternatives section.

Funding History

OpenAI’s valuation trajectory reflects the AI hype cycle:

The company’s valuation has increased 17x in just over two years. That meteoric rise is exactly what attracts investor interest—and exactly what should give you pause.

Can You Buy OpenAI Stock?

The direct answer: Almost certainly not.

OpenAI is a private company. Its shares don’t trade on any public stock exchange. You cannot open a brokerage account and buy OPAI the way you’d buy AAPL or MSFT.

For the small subset of investors who might qualify, here’s the reality:

If You’re an Accredited Investor

You have theoretical access through secondary market platforms. These are private marketplaces where existing shareholders (employees, early investors) sell their stakes to new buyers.

The catch: Even accredited investors face significant barriers:

• Extremely limited supply — OpenAI shares rarely come to market
• Long waitlists — Six months or longer is common
• High minimums — $25,000 at the low end, often $50,000-$100,000
• Premium pricing — Expect to pay above the last funding round valuation
• Lock-up periods — You may not be able to sell for 1-2 years

If You’re a Retail Investor

You cannot buy OpenAI stock directly. No exceptions, no workarounds, no “secret” platforms.

Skip ahead to the Alternatives for Retail Investors section—that’s where your real options lie.

Do You Qualify as an Accredited Investor?

The SEC defines accredited investors as individuals who meet at least one of these criteria:

Income Test

• $200,000+ annual income for the past two years (individual), OR
• $300,000+ combined with spouse
• Reasonable expectation of the same income this year

Net Worth Test

• $1 million+ net worth, excluding your primary residence

Professional Credentials

• Series 7, 65, or 82 licenses
• Certain professional designations (CFA, etc.)

Reality Check: About 13% of U.S. households qualify as accredited investors. If you don’t qualify, the secondary market platforms won’t work for you—but Microsoft and AI ETFs will. Skip to the alternatives section.

How to Invest in OpenAI (If Accredited)

If you meet accredited investor requirements and want to pursue OpenAI shares, here are the platforms that have historically offered access:

Secondary Market Platforms

EquityZen

• Minimum: $25,000+
• Fees: 5-8% of transaction
• Availability: Limited—join the waitlist
• Process: Create account, verify accreditation, request allocation, wait

EquityZen appears to be the most accessible platform for OpenAI shares, though “accessible” is relative. Expect months of waiting and no guarantee of allocation.

Hiive

• Minimum: $50,000+
• Fees: 5-10%
• Availability: Extremely limited
• Focus: Higher-net-worth investors

Forge Global

• Minimum: $100,000+
• Fees: 5-10%
• Availability: Extremely limited
• Focus: Institutional and high-net-worth

The Reality of Secondary Market Investing

Even if you qualify and find available shares, consider what you’re buying into:

1. You’re paying a premium. Secondary market prices often exceed the last funding round valuation. At $500 billion, you’re buying at 42x revenue.

2. You can’t sell easily. There’s no liquid market. Your exit options are IPO (years away), acquisition (unlikely at this valuation), or finding another secondary buyer (difficult).

3. You have no information rights. Private company shareholders don’t get quarterly earnings calls or SEC filings. You’re investing blind.

4. You may face dilution. OpenAI burns $8 billion annually. Future funding rounds will create new shares, diluting your percentage ownership.

Alternatives for Retail Investors

You don’t need accreditation to get exposure to OpenAI’s success—or the AI revolution broadly. Here’s how:

1. Microsoft (MSFT) — The OpenAI Proxy

Microsoft is the single best way for retail investors to benefit from OpenAI’s success.

Why it works:

• $13+ billion invested in OpenAI across multiple rounds
• Exclusive licensing for OpenAI models in Microsoft products
• Azure OpenAI Service generates enterprise AI revenue
• Revenue sharing from OpenAI’s commercial success
• Copilot integration brings AI to Office, Windows, and GitHub

The math: If OpenAI’s $500 billion valuation holds and Microsoft owns even 10% economic interest, that’s $50 billion in value—roughly 2% of Microsoft’s market cap. Not transformative, but meaningful.

More importantly: Microsoft is building its entire product strategy around AI. Even if OpenAI specifically disappoints, Microsoft’s AI investments extend far beyond one partnership.

2. Nvidia (NVDA) — The Picks and Shovels Play

Every AI company—OpenAI included—runs on Nvidia GPUs. If you believe in AI broadly, Nvidia captures value across the entire ecosystem.

Why it works:

• OpenAI’s training runs require thousands of Nvidia H100/H200 chips
• Data center revenue has exploded with AI demand
• Near-monopoly position in AI training hardware

The risk: Nvidia trades at premium valuations and faces eventual competition from AMD, Intel, and custom chips from hyperscalers.

3. AI-Focused ETFs

For diversified AI exposure without picking individual stocks:

Note: None of these ETFs hold OpenAI directly (it’s private). They provide sector exposure, not OpenAI-specific investment.

4. Alphabet (GOOGL) — The Competitor Play

If you believe in AI but worry about OpenAI’s valuation or governance, Google offers an alternative thesis:

• Gemini competes directly with GPT models
• Major investor in Anthropic (Claude AI)
• Decades of AI research through DeepMind and Google Brain
• Distribution advantage through Search, Android, and Cloud

Alphabet trades at lower multiples than pure-play AI investments while offering significant AI upside.

5. Wait for the IPO

The most straightforward approach: wait until OpenAI goes public, then buy shares like any other stock.

Advantages:

• No accreditation requirements
• Liquid market with transparent pricing
• SEC disclosure requirements provide information
• Can start with any amount (fractional shares available)

Disadvantages:

• Unknown timeline (analysts estimate 4-6 years)
• May miss early gains
• IPO pricing may be expensive

OpenAI Valuation: Is $500 Billion Justified?

OpenAI’s current valuation demands scrutiny. At $500 billion, the company trades at approximately 42x its estimated $12 billion annualized revenue.

Valuation Context

OpenAI’s multiple is 3-6x higher than public AI leaders. That premium requires extraordinary growth to justify.

What Would Justify $500 Billion?

For OpenAI to “grow into” its valuation at a reasonable 10x revenue multiple, it would need:

• $50 billion in annual revenue
• That’s 4x current revenue
• At 100% annual growth, achievable in 2 years
• At 50% annual growth, requires 3-4 years

The growth assumptions aren’t impossible—but they require near-perfect execution in an increasingly competitive market.

The Down-Round Risk

Private market valuations don’t always translate to public markets. Consider Instacart: valued at $39 billion in private markets in 2021, it IPO’d at $9.9 billion in 2023—a 75% haircut.

If you buy OpenAI shares at $500 billion and the IPO prices at $300 billion, you’ve lost 40% before the stock ever trades publicly.

Risks of Investing in OpenAI

Beyond valuation, OpenAI carries specific risks that investors should understand:

Governance Risk

The November 2023 board crisis—where Sam Altman was fired and rehired within days—exposed serious governance dysfunction. The nonprofit board’s ability to fire the CEO of a $500 billion company created chaos and raised questions about decision-making authority.

OpenAI must convert from its unusual nonprofit-controlled structure to a traditional for-profit by December 2025, or risk losing $22.5 billion in committed funding. This restructuring creates uncertainty about future governance.

Competition Risk

OpenAI’s lead is narrowing:

• Google’s Gemini matches GPT-4 on many benchmarks
• Anthropic’s Claude is preferred by many developers for safety and reliability
• Meta’s Llama offers open-source alternatives
• Numerous startups are attacking specific use cases

The moat around large language models is unclear. Training costs are dropping, open-source alternatives are improving, and customers are increasingly multi-model.

Financial Risk

OpenAI burns approximately $8 billion annually on compute, talent, and research. At that rate, even massive funding rounds provide limited runway. The company must either:

• Continue raising at ever-higher valuations
• Dramatically increase revenue
• Cut research spending (potentially ceding leadership)

Regulatory Risk

AI regulation is accelerating globally. The EU AI Act imposes new requirements. U.S. lawmakers are considering various frameworks. Antitrust scrutiny of the Microsoft partnership continues.

Any of these could impact OpenAI’s business model, growth trajectory, or competitive position.

When Will OpenAI Go Public?

Official Position

OpenAI has made no official IPO announcement. Sam Altman has stated the company is focused on building artificial general intelligence (AGI), not financial engineering.

Analyst Speculation

Most analysts expect 4-6 years before a potential IPO, based on:

• Current private market liquidity (no pressure to go public)
• Ongoing corporate restructuring
• Regulatory uncertainty around AI
• Desire to maintain operational flexibility

Historical Comparisons

OpenAI, founded in 2015, is approaching its 10th year as a private company. Given the SpaceX precedent (same investor base, similar “mission-driven” positioning), an extended private period is plausible.

Signs to Watch

• S-1 filing with the SEC (required 15+ days before IPO)
• CFO hire with public company experience
• Audit firm changes to Big Four
• Secondary market activity increasing
• Lock-up expirations for early employees

The Bottom Line

Can you buy OpenAI stock? If you’re a retail investor, no. If you’re an accredited investor with $25,000+ and patience for six-month waitlists, maybe—but you’ll pay premium prices for illiquid shares in a company with governance questions and a $500 billion valuation to justify.

Should you try? For most investors, the answer is no. The risk-reward at current valuations, combined with the illiquidity and information disadvantage, makes secondary market OpenAI shares a poor bet.

What should you do instead?

1. If you want OpenAI exposure: Buy Microsoft. You get the partnership economics plus a diversified, profitable, dividend-paying business.

2. If you believe in AI broadly: Consider Nvidia, Alphabet, or AI-focused ETFs. You’ll capture the trend without betting everything on one company.

3. If you’re patient: Wait for the IPO. You’ll get transparent pricing, liquid markets, and SEC disclosures. Yes, you might miss some upside—but you’ll also avoid the very real possibility of buying at the top.

The AI revolution is real. OpenAI is a major player. But the best investment opportunities aren’t always the most obvious ones—and sometimes the smartest move is buying the public company that already owns a piece of the private one.
