OpenAI, Anthropic and SpaceX May Create the Largest Tech Exits in U.S. History

OpenAI, Anthropic and SpaceX are on track to generate more exit value than every U.S. venture-backed public offering since 2000 combined, according to a new PitchBook-NCVA venture report cited by TechCrunch on July 9, 2026. The claim underscores how the AI boom and SpaceX’s long-awaited market debut are reshaping the scale of private-market outcomes — and how far today’s top startups now sit above even the biggest tech exits of the last quarter-century.

The numbers are staggering. SpaceX has already reached a public-market valuation of $1.77 trillion, while OpenAI and Anthropic are both being discussed in the trillion-dollar range as they move closer to potential listings. Put together, the three companies could surpass $4 trillion in value, a figure that would dwarf the roughly $70 billion in U.S. IPO proceeds recorded by the Securities and Exchange Commission last year.

That comparison is not perfectly apples-to-apples, because the report is measuring value created rather than cash raised, and it excludes non-U.S. giants that have also shaped tech wealth over the past 25 years. But even with those caveats, the conclusion is hard to miss: the next wave of public offerings may redefine what counts as a major technology exit.

Why this moment matters for tech markets

This matters because the public-market debut of a handful of companies is now large enough to overwhelm an entire generation of prior venture-backed exits. For investors, founders and bankers, that changes expectations around liquidity, fundraising and the timeline to go public.

The report’s central point is that the market is not just seeing bigger companies — it is seeing a different category of company size altogether. The combination of AI infrastructure demands, extreme private valuations and longer startup lifespans has created a class of businesses that can remain private for years while still scaling to unprecedented levels.

According to the Venture Monitor data highlighted by TechCrunch, the pending OpenAI and Anthropic exits, together with SpaceX’s IPO, would create more value than all U.S. VC-backed exits since 2000.

What the numbers actually show

The headline comparison is striking, but the underlying math is more nuanced. The report is looking at value generated by exits, not simply the cash that changed hands during an IPO or sale. That means the statistic captures the implied worth of these companies at listing rather than the amount of capital they raised from public investors.

Even with that distinction, the scale is extraordinary. SpaceX’s $1.77 trillion valuation alone would make it one of the most valuable public companies ever. If OpenAI and Anthropic reach the valuation levels now being discussed, their combined market value could push the total above $4 trillion. By contrast, U.S. IPO proceeds totaled only about $70 billion in 2025, according to the SEC.

How did the tech exit landscape get here?

The answer is that startups are staying private much longer, and the most valuable ones are raising money at a pace once reserved for public companies. Instead of going public early to finance growth, leading firms can now tap large private rounds, sovereign wealth capital, strategic investors and late-stage funds willing to back massive valuations.

AI has accelerated that pattern. Training frontier models requires enormous spending on chips, data centers, talent and energy. That capital intensity has encouraged repeated fundraising cycles and helped push valuations higher than many traditional software businesses ever reached before an IPO.

Longer private lives, bigger public debuts

The private-market hold period has stretched because founders no longer need an IPO as early as they once did. In the 2000s, companies often went public with less revenue and a shorter track record. Today, the most prominent startups can remain private long enough to grow into near-industrial-scale enterprises before listing.

That delay can make the eventual public debut look even more dramatic. A company that might once have gone public at a modest valuation can instead spend years compounding growth and arrive on the market at a far larger number.

AI’s capital demands are changing the rules

AI is different from the software wave that came before it because frontier model development is expensive in a way that earlier internet platforms were not. Training and serving large models requires specialized hardware, advanced networking, and continuous spending on compute. That makes the funding requirements closer to those of heavy industry than classic venture software.

As a result, the market is rewarding scale, capital access and technical differentiation all at once. That combination helps explain why the valuations attached to leading AI labs have moved so quickly into territory that was once reserved for the world’s largest public companies.

Why the comparison has limits

The report’s conclusion is powerful, but it is also deliberately qualified. The figure does not include major non-U.S. listings such as Alibaba, so it is focused specifically on American venture-backed exits. It also leaves out the huge amount of value created by companies that transformed technology after they had already gone public.

That matters because some of the biggest consumer and platform shifts of the last two decades occurred inside public companies, not startups. The iPhone launch, the rollout of Android, and the rise of YouTube and Instagram all created enormous value, but they would not appear in a tally of venture-backed IPO proceeds.

So while the headline suggests a once-in-a-generation concentration of value, it is best understood as a measure of the venture market’s exit pipeline rather than a complete accounting of tech innovation.

Which earlier tech milestones does this eclipse?

This likely eclipses many of the landmark exits that defined modern tech investing. The period since 2000 included the public listings of Google, Tesla and Meta, plus multibillion-dollar acquisitions such as LinkedIn, Slack and WhatsApp. Those deals reshaped venture expectations for years.

But even the most famous of those exits now look comparatively modest when set against a SpaceX IPO valued at $1.77 trillion. Uber’s 2019 IPO, once considered one of the biggest public debuts of the decade at $84 billion, would amount to less than 5% of SpaceX’s implied public-market value.

• Google went public in 2004 and became one of the defining internet companies of its era.
• Tesla’s 2010 IPO helped set the template for long-duration public-company growth stories.
• Meta’s 2012 debut cemented the social platform era.
• LinkedIn, Slack and WhatsApp were sold for more than $20 billion each.
• Uber’s $84 billion IPO was considered enormous at the time, but looks small next to today’s mega-exits.

What this means for founders and investors

The biggest immediate implication is psychological: the ceiling has moved. Founders building at the frontier can now plausibly imagine public-market outcomes that were not realistic for earlier generations of startups. That can influence everything from recruiting to fundraising strategy to how long a company stays private.

For investors, the report suggests that the distribution of returns may become even more concentrated. If a tiny number of companies generate more exit value than decades of prior venture activity, capital will continue to cluster around the perceived winners, especially in AI and space.

It also creates pressure on the infrastructure that supports the market. When a few transactions become this large, exchanges, underwriters, regulators and clearing systems all face new challenges around scale, liquidity and price discovery.

How public markets could adapt

Public markets may have to become more flexible to handle companies with enormous valuations and complex capital structures. Investors will also have to decide how to price businesses that have not yet shown a traditional path to profitability but already command outsized strategic importance.

That tension is especially visible in AI, where demand for compute and the race for model leadership can justify spending levels that would have seemed unsustainable in older software markets. The result is a market that increasingly rewards strategic necessity as much as near-term earnings.

The broader story behind the headline

At its core, this is not only a story about one IPO, or even three. It is a story about the changing size of innovation itself. The last 25 years produced companies that redefined search, mobility, social media and online communication. The next phase is producing businesses whose value may outstrip the entire earlier venture ecosystem.

That does not mean older innovations were smaller in importance. Many of the most consequential products were launched by public companies that do not fit neatly into venture exit statistics. But from the standpoint of the startup economy, the scale now being discussed around OpenAI, Anthropic and SpaceX marks a clear break from the past.

In practical terms, the report suggests that the next generation of tech wealth may be even more concentrated, more capital-intensive and more difficult to measure with the old tools of venture accounting. In symbolic terms, it shows that the most ambitious companies in the market are no longer just rewriting product categories — they are rewriting the size of the exit itself.

Timeline of major tech exit milestones

Here is a simplified look at the milestones that frame today’s comparison.

What happens next?

The immediate question is whether OpenAI and Anthropic actually reach the public market and at what terms. The broader question is whether the current valuation regime can hold if AI revenue growth, compute costs and competition evolve faster than investors expect.

For now, the market is signaling extraordinary confidence in a small group of companies building foundational technologies. If those exits materialize near the levels now being discussed, they will not merely be large IPOs. They will be historical events that redefine the size of venture success in the United States.

And even if the exact valuations change, the direction of travel is already clear: the most valuable startups are no longer just beating past benchmarks. They are beginning to make the entire history of venture-backed exits look small.
