Anthropic’s IPO Could Surpass SpaceX as the Largest in History

Anthropic could be heading towards one of the biggest IPOs ever. The AI company has confidentially filed for a public listing, while reports suggest investors are considering a valuation of at least $2 trillion. 

If that figure becomes reality, Anthropic could overtake SpaceX as the company with the largest IPO valuation in history.

The headline valuation, however, is only part of the story. Anthropic's rapidly growing revenue, demanding AI infrastructure costs, shifting macro conditions, limited share supply and regulatory risks will all influence whether investors ultimately support such a valuation.

Key Takeaways

• Anthropic has filed confidentially for an IPO, with reports suggesting investors could value the AI company at $2 trillion or more.
• A valuation above roughly $1.77 trillion could put Anthropic ahead of SpaceX's 2026 IPO record, but the final valuation and offering size remain unconfirmed.
• Anthropic's IPO outlook will depend on revenue growth, macro conditions, limited share supply, short positioning after listing, and regulatory risks.

Why Anthropic Could Challenge SpaceX's IPO Record

Anthropic has already taken a formal step towards becoming a public company. On June 1, 2026, the AI company confirmed that it had confidentially submitted a draft registration statement to the U.S. Securities and Exchange Commission.

That filing does not mean Anthropic has finalised its IPO valuation or listing date. Those details will depend on the company's eventual registration documents, market conditions and discussions with investors.

Still, expectations surrounding the potential listing have become substantial. Financial Times reporting indicated that some investors were considering a valuation of at least $2 trillion, with October reportedly viewed as a possible timing for the offering.

That figure matters because SpaceX recently established a new benchmark for large IPOs. Its June 2026 offering raised $75 billion at $135 per share. Reuters reported that the deal could eventually reach $86.2 billion if the overallotment option were fully exercised.

SpaceX's IPO valuation was roughly $1.77 trillion. Therefore, a $2 trillion valuation for Anthropic would put it above SpaceX on that particular measure.

The distinction between IPO valuation and money raised is important, though. A company can have a higher valuation without raising more capital through its offering. 

Anthropic would therefore need to be assessed using both metrics when determining whether it actually becomes the largest IPO in history.

Anthropic's Rapid Revenue Growth Is Driving the Valuation

The main argument behind Anthropic's enormous valuation is its rapid commercial growth.

Anthropic said in May that its annualised revenue run rate had reached $47 billion when it announced a $65 billion Series H funding round at a $965 billion post money valuation. More recent reporting has put the company's annualised revenue run rate at around $65 billion.

These figures are not the same as audited annual revenue. A revenue run rate extrapolates current performance over a full year, making it useful for showing the pace of growth but less definitive than reported historical revenue.

The bigger valuation argument comes from Anthropic's expectations for future growth.

Reuters reported that Anthropic is working with a 2028 revenue forecast of approximately $190 billion to $200 billion. If that forecast is achieved, it would represent a dramatic increase from the company's current run rate.

Such expectations help explain why investors may be willing to discuss valuations far above Anthropic's previous private market valuation.

There is also an important trade off. Building and operating frontier AI systems requires enormous amounts of computing infrastructure. 

Revenue growth therefore needs to be considered alongside the cost of training and running models, data centre capacity and other infrastructure requirements.

For IPO investors, the question is not simply whether Anthropic can grow quickly. It is whether that growth can eventually translate into sustainable economics at a valuation measured in trillions of dollars.

Anthropic vs SpaceX: What Would It Take to Set a New IPO Record?

The comparison with SpaceX provides a useful benchmark.

SpaceX's offering was a landmark event because of both its fundraising size and valuation. Its shares also initially had a relatively limited public float, creating unusual trading dynamics after the listing.

Anthropic's potential record would depend on its final offering structure.

If the company ultimately prices its shares at a valuation above SpaceX's IPO valuation, it could claim the record based on valuation. But if the comparison is based on proceeds raised, the calculation would be different.

That distinction should remain clear because headlines about a "$2 trillion IPO" can otherwise create confusion between the company's total market value and the amount of capital it receives from selling new shares.

For now, Anthropic's reported $2 trillion figure remains an expectation rather than a confirmed IPO price.

Could Limited Supply and Short Positioning Amplify Volatility?

Anthropic is not yet a publicly traded company, so there is no confirmed public market short interest and no current Anthropic short squeeze.

The more relevant issue before the IPO is share supply.

Secondary market reporting has indicated that Anthropic shares have become increasingly scarce as its implied private valuation has risen. 

Strong demand combined with limited willingness from existing shareholders to sell can create significant differences between the price buyers are willing to pay and the amount of stock actually available.

That dynamic could become relevant again during an IPO.

SpaceX provides an example of how a limited public float can affect trading. According to recent reports, fewer than 5% of SpaceX's shares were initially available for trading. Later lockup expirations substantially increased the number of shares available to investors.

If Anthropic also enters the public market with a relatively small float, demand could potentially create significant price volatility.

A short squeeze would require another condition: meaningful short positioning after Anthropic becomes publicly traded. If short sellers build large positions and the share price rises sharply, they could be forced to buy shares to close their positions, potentially adding further buying pressure.

That remains a hypothetical post IPO scenario, not something currently happening with Anthropic.

Why the Macro Environment Could Matter

Anthropic's IPO would arrive against a more complicated financial backdrop than the headline valuation might suggest.

High growth companies are particularly sensitive to interest rates because much of their perceived value comes from expected future earnings and cash flows. 

When bond yields rise, those future cash flows are generally discounted more heavily, which can put pressure on high valuation stocks.

Reuters reported in August that long term real yields were near multi year highs while AI companies and hyperscalers continued to increase borrowing to fund infrastructure expansion.

The Federal Reserve also remains an important variable. Recent reporting showed disagreement among policymakers over the direction of monetary policy, with three officials dissenting in favour of a rate increase at the July meeting.

That does not mean higher rates will prevent Anthropic from going public. Strong investor demand for AI exposure could remain sufficient to support a major offering.

The more important point is that Anthropic's valuation will be tested against the cost of capital available when the IPO actually occurs.

A $2 trillion valuation may appear reasonable to investors during a period of strong liquidity and falling yields but considerably more demanding if rates and bond yields remain elevated.

Regulatory and Legal Risks Anthropic Faces

Anthropic's growth story also comes with regulatory uncertainty.

The company operates at the frontier of artificial intelligence, meaning its products can attract scrutiny over national security, export controls and the potential risks associated with advanced AI systems.

In June, Reuters reported that the U.S. government temporarily restricted access to Anthropic's latest Fable 5 and Mythos 5 models before the restrictions were subsequently lifted following additional safeguards.

Such developments demonstrate why regulation could become an important consideration for IPO investors.

Anthropic has also developed its own Responsible Scaling Policy. The policy provides a framework for how the company intends to manage risks associated with increasingly capable AI systems.

Legal issues are another consideration. Anthropic faces copyright litigation related to the use of material in AI training, adding another source of potential uncertainty around the company's future costs and operations.

None of these developments automatically make an Anthropic IPO unattractive. They do, however, show why investors need to evaluate more than revenue growth when considering a valuation in the trillions of dollars.

What Could Stop Anthropic From Breaking the Record?

The biggest risk to the record breaking thesis is that expectations become too high.

Anthropic's reported revenue growth is extraordinary, but sustaining that pace becomes progressively harder as the company's base expands. 

A slowdown in enterprise demand, increased competition or higher infrastructure costs could challenge the assumptions behind a $2 trillion valuation.

Competition is another factor. Anthropic is competing in a rapidly developing AI market that includes OpenAI and major technology companies with substantial computing and financial resources.

Macroeconomic conditions could also change before the IPO. Higher Treasury yields could reduce appetite for companies whose valuations depend heavily on future growth.

Regulation presents another uncertainty. New restrictions could affect Anthropic's ability to deploy certain models or expand into specific markets, while copyright disputes could increase costs or create additional legal obligations.

There is also the possibility that public market investors simply refuse to pay the valuation expected by private market investors.

A high private market valuation does not guarantee an equally high public market valuation. IPO pricing ultimately depends on what institutional and retail investors are willing to pay when actual shares become available.

What Anthropic's IPO Could Mean for AI and Financial Markets

A successful Anthropic IPO at or above $2 trillion would have significance beyond one company.

It could provide another major valuation benchmark for the AI sector and influence how investors assess other private AI companies. 

OpenAI and other large AI businesses could face greater pressure to demonstrate comparable revenue growth or establish clearer paths towards public market valuations.

The IPO could also affect AI infrastructure companies. If investors continue allocating substantial capital towards AI, demand for computing capacity, data centres and related infrastructure could remain strong.

The opposite scenario would also be significant.

If Anthropic struggles to achieve its expected valuation, investors could interpret that as evidence that private AI valuations have moved too far ahead of underlying economics. That could affect sentiment towards other high valuation technology companies.

For crypto markets, the connection is indirect but still relevant. AI and cryptocurrency are both sensitive to broader liquidity and risk appetite. 

A major technology IPO can therefore become another indicator of how willing investors are to accept high valuation and high growth opportunities.

That does not mean Anthropic's IPO would automatically determine crypto prices. It would instead provide another signal about the broader appetite for risk across financial markets.

Anthropic's IPO Could Set a New Benchmark

Anthropic has taken a significant step towards becoming a public company, but the record breaking headline remains conditional. 

A valuation above $2 trillion would put the AI company ahead of SpaceX's roughly $1.77 trillion IPO valuation, yet the final number will depend on actual investor demand and market conditions.

The company's revenue growth gives investors a strong reason to consider a premium valuation, but that growth must be weighed against infrastructure costs, interest rates, limited share supply and regulatory uncertainty. 

Until Anthropic publishes definitive IPO terms, the $2 trillion figure should be treated as an expectation rather than a confirmed outcome.
