Anthropic Eyes $2 Trillion IPO as Investors Weigh Safety Risk

Anthropic's investors are targeting a $2 trillion valuation for an October initial public offering that would surpass SpaceX's record June debut. The Claude maker filed a confidential S-1 with the SEC on June 1 and is working with Morgan Stanley, Goldman Sachs, and JPMorgan on the listing.

Weeks before the expected roadshow, researcher Jacob Coxon resigned publicly, and alignment lead Evan Hubinger endorsed his warning, estimating a greater-than-10% chance of AI-driven human extinction within the decade. Evaluating your own check up on your financial health before considering an IPO where the company's own senior researchers have publicly validated existential risk is a step the prospectus alone may not prompt you to take.

Anthropic's October IPO could hit $2 trillion, the largest public offering ever

Six Anthropic investors told the Financial Times they expect the company to go public at a valuation of $2 trillion or more, Investopedia wrote. The figure would more than double Anthropic's $965 billion post-money valuation from a $65 billion Series H round in May 2026 and exceed SpaceX's $1.77 trillion June debut.

Annualized revenue was running at $47 billion in May, and investors are underwriting projections of $100 billion to $120 billion by December, Yahoo Finance detailed. No senior Anthropic executive has publicly confirmed the $2 trillion target, meaning the figure represents investor expectations rather than company guidance.

Researcher Jacob Coxon resigned publicly on September 8

Coxon, a 27-year-old British pretraining researcher who worked at both OpenAI and Anthropic over the past three years, announced his resignation on X, accusing both companies of racing toward self-improving superintelligence. Key details of the fallout include the following.

• Coxon's posts received more than 153 million views within 36 hours.
• He accused AI labs of "gambling with our lives" by pursuing superintelligence without adequate safeguards.
• Dozens of politicians responded, including Illinois Governor JB Pritzker, who called for immediate action.

The resignation landed weeks before Anthropic's expected IPO roadshow, creating a timing collision between the company's most visible safety controversy and its largest-ever capital markets event, Time reported.

Alignment lead Evan Hubinger endorsed the warning with a 10% extinction estimate

Hubinger, who leads Anthropic's alignment stress-testing team, responded publicly to Coxon's posts, writing that Coxon was "correct" and that he personally estimates the odds of AI-driven human extinction at greater than 10% within the next decade, CNBC confirmed. Hubinger added that Anthropic "is trying its best, but we do not yet have a plan to solve alignment for superintelligence and are not clearly on track to."

The statement is significant for prospective IPO investors because it came from a current senior employee, not a former critic. Scientific American framed it as an unprecedented public admission from inside a company building the systems in question. Hubinger stressed that current AI models present a relatively low risk and that his concerns center on future superintelligent systems, but the double-digit probability attached to a company-ending scenario is a risk factor the S-1 will need to address.

Forbes argues public investors would enter after private backers captured the steepest gains

Amazon, Google parent Alphabet, and Sequoia Capital are among Anthropic's largest private investors, and Forbes analyst Jim Osman argued that public market buyers would be entering a trade where the biggest returns have already been taken. The $965 billion Series H valuation in May already represented a fivefold increase from the $183 billion Series F valuation reported just months earlier.

Osman warned that IPO investors face limited board influence over a company making massive compute commitments and spending at a pace that could consume capital faster than revenue grows. Amazon and Google hold cloud infrastructure agreements with Anthropic that guarantee compute access but also tie the company to billions in future spending obligations your investment helps fund.

The S-1 prospectus will reveal audited financials for the first time

Anthropic filed a confidential draft S-1 registration statement with the SEC on June 1, and the public version will convert years of private-round projections into audited line items, Forbes detailed. Gross margin on selling AI inference, the actual size of the compute bill, and the customer concentration behind the $47 billion run rate will all become visible for the first time.

The gap between the $47 billion May run rate and the $100 billion to $120 billion December projection that investors are underwriting requires roughly a 2- to 2.5-times revenue jump in seven months. For your portfolio, the S-1 is the document that either validates or challenges that trajectory, and waiting for its public release before committing capital gives you audited data the current reporting does not provide.

CEO Dario Amodei responded with a public essay calling for an AI slowdown

Amodei published a 3,800-word essay on September 12 arguing that the mounting risks of AI warranted a coordinated slowdown among leading labs, Time wrote. The essay arrived four days after Coxon's resignation and represented the CEO of a company weeks from an IPO publicly acknowledging that the technology his company builds may require deliberate restraint.

The tension between racing to justify a $2 trillion valuation and advocating for a slowdown in the same month defines the risk profile prospective investors need to evaluate. Anthropic's positioning as the "safety-focused" AI lab gives it a differentiated brand, but the Coxon and Hubinger disclosures suggest that even the safety-focused approach has not resolved the core alignment challenge, a nuance the S-1 risk factors will need to communicate clearly.

Bottom line

Anthropic's $2 trillion IPO target would make it the largest public offering in history, backed by revenue that has grown from $1 billion in late 2024 to a $47 billion run rate by May 2026. The company has raised capital from Amazon, Google, and Sequoia, filed a confidential S-1, and is working with three of Wall Street's largest banks on the listing.

Before you start investing in an IPO where a senior alignment researcher publicly estimated a greater-than-10% chance of the technology causing human extinction, reading the public S-1 when it becomes available and evaluating the risk factors against your own timeline is the minimum diligence the situation demands. The growth numbers are extraordinary, but so are the warnings coming from inside the building.
