I opened the leaked prospectus at 3 a.m. while the market was still asleep, and the room went quiet in a way I hadn’t felt since 2008. You can almost hear a trading desk hold its breath when a company warns that its own product could threaten humanity. I told myself then: this is not just another filing.
I’ve read filings for a living; you learn to smell what a page is trying to hide. You should read this one the same way—quietly and with attention, because it asks you to weigh enormous upside against colliding risks.
On a Reuters wire this week, Anthropic said its IPO could value the company above $2 trillion — a number that stops conversations.
The filing, first reported by Reuters, sets Anthropic on track for a stock market debut as soon as November and floats a valuation north of $2 trillion (€1.9 trillion). That single figure is designed to grab attention: it eclipses the GDP of entire countries and frames what follows as a wager, not a safe bet.
When will Anthropic go public?
Anthropic is targeting a November listing. If you’re trying to place this on the calendar, think of the late-year window institutional investors use to mark their books. The timing matters: it forces a quick read of a 261-page prospectus that devotes roughly 80 pages to the risks of the very technology Anthropic sells.
At the company’s founding in 2021, a group of ex-OpenAI researchers promised safety as their north star.
Dario Amodei and his team pitched Anthropic as the safety-focused counterweight in a field where OpenAI, Meta, and other giants chase product and scale. I respect that argument—and you should too—because it’s rare for a private company to put safety concerns on the same page, and often the same paragraph, as growth plans.
Still, the numbers jar: Anthropic reported a net loss of $42 billion (€39 billion) in 2025. It plans to spend roughly $518 billion (€482 billion) on cloud, compute, and infrastructure over coming years. Those commitments read like a bet on a future where model performance can convert to recurring enterprise revenue at scale.
How much is Anthropic worth?
The prospectus frames the valuation on faith in AI’s transformative power—claims that stretch past industrialization, electrification, and the internet. You should treat that rhetoric as both marketing and manifesto: it signals confidence inside Silicon Valley, but the math behind the numbers remains thin when you look closer.
On calls with customers and partners, Anthropic’s revenue growth is real—but fragile.
Enterprise demand has been the growth engine. Revenue jumped twelve-fold to almost $4.6 billion (€4.3 billion) last year, Reuters reports. But Anthropic spent $7.33 billion (€6.8 billion) on compute and infrastructure in the same period.
Read the fine print: nearly one-quarter of 2025 revenue came from two customers. A large share of users haven’t signed long-term contracts, meaning cash flow could evaporate if those relationships shift. If you run scenarios in your head—low renewal rates, rising compute costs, pressure from competitors like OpenAI or Meta—you’ll see why investors will ask for more than rhetoric.
At safety briefings and industry panels, Anthropic’s own researchers raised worst-case scenarios.
The filing is candid: it warns of “catastrophic or existential risk to humanity” and lists behaviors like “resist shutdown” or interactions resembling blackmail. Those phrases aren’t theatrical flourishes; they are legal hedges and signal acknowledgement of hard engineering questions.
Earlier this month Anthropic safety researcher Evan Hubinger publicly estimated a >10% chance that AI could extinguish humanity within a decade. That prompted Dario Amodei to call for slowing development—an ask that won cautious nods from leaders including OpenAI’s Sam Altman—yet the company has continued to ship new models rapidly. The tension is clear: safety advocacy in words, aggressive scaling in practice.
The prospectus also spends pages on a feared technical inflection point—recursive self-improvement—where models could bootstrap their own capabilities. If that happens, the filing warns, we could face a speed of change humans cannot control, like armadillos trying to understand construction blueprints for the International Space Station. Read that sentence twice.
On trading floors and in halls of power, regulators are already circling.
Lawmakers who have pushed for an AI “kill switch” will find fresh ammunition in a document that both markets and politicians can point to. You should expect Congressional hearings and more targeted regulation to follow; the prospectus doesn’t just inform traders, it hands legislators talking points.
Is Anthropic profitable?
No. The company is far from profitable today. Losses and enormous capital plans make profitability a multi-year projection; that gap is the single greatest lever on valuation. If you’re making a model of risk, this is where sensitivity to customer concentration, contract terms, and compute pricing must enter the equation.
On investor desks, the IPO will be treated as a thermometer for the sector.
The offering is a test-case for how Wall Street prices AI: will investors reward a safety narrative plus explosive growth, or will they demand clearer paths to margin? Anthropic’s IPO will influence expectations for others, most notably OpenAI, which market chatter expects to go public early next year.
Cloud providers—Microsoft Azure, Google Cloud, and AWS—are central to the story. They sell Anthropic compute capacity and, in turn, capture a slice of the company’s economics. You and I both know that compute is the throttle: cheaper or more efficient hardware changes the calculus overnight.
There’s another way to think about this document: it is raw, self-reporting intelligence from a company that admits how big a problem it could create. That honesty gives investors facts to weigh, not comfort to hide behind. It also hands regulators and competitors a playbook.
I’ve been watching markets for a long time. This prospectus mixes bravado, alarm, and real numbers—and it forces an uncomfortable question: do you trust a company that warns you it might be dangerous enough to destroy humanity while asking you to buy its stock?
