There has never been a company like Anthropic.

• It owes almost $650 billion for computing, generates eye-popping revenue per employee and wants every investor to know that its product poses existential risks to humanity.

Why it matters: The future of the AI race, the market and the global economy rests within Anthropic's IPO prospectus, where some of Silicon Valley's most seasoned investors found new reasons to be bullish.

• They also found warning signs. A wager on Anthropic is a bet not just that AI will deliver on its enormous promise, but that customers will keep spending at a rate that keeps pace with massive computing costs.
• It's also a bet that Anthropic can continue to deliver models good enough to justify premium prices, even as competition intensifies and cheaper alternatives improve.

The filing had fodder for a variety of perspectives. (See what Claude and OpenAI's ChatGPT say about whether they'd invest.)

The good: Anthropic has nearly 2,000 customers paying it $1 million or more per year, and 250 paying $10 million or more. Half the Fortune 500 pays the company $100,000 a year, and those customers spent less than 0.1% of their total expenses in the third quarter on Anthropic.

• "We are so early," Ben Bajarin, a longtime tech analyst, said on X.
• The company had more than $130 billion in cash and short-term investments on hand as of June 30, about $10 billion less than the total it's raised, pointing to substantial financial discipline, some investors said.
• As noted, Anthropic had revenue per employee of $6.6 million as of the end of the third quarter, only slightly lower than Nvidia's, which is typically seen as one of the most efficient operators in tech.

The bad (or maybe bad): Anthropic's five largest customers accounted for approximately 25% of revenue during the first nine months of 2026.

• Many Anthropic customers pay by usage and don't make multiyear commitments. But the company's computing obligations extend for years and include minimum payments regardless of how much capacity it actually uses.
• Nearly 50% of Anthropic's first-half revenue came through cloud marketplaces operated by Amazon, Google and Microsoft — companies that are also investors, computing suppliers and competitors.
• That makes hyperscalers huge winners, since they collect revenue in multiple ways, once by providing compute and also as a platform fee.

The surprising/intriguing: Anthropic's deal with Elon Musk is expanding.

• According to Anthropic's paperwork, the company's payments to SpaceX are now seen reaching $3.1 billion a month and up to $120.5 billion on computing through 2029, up from $1.25 billion a month at the time of SpaceX's IPO filing. (Yes, but: Either side can cancel that deal with 90 days' notice.)
• Anthropic's cash stockpile left some to wonder if the company has been paying a lot of its bills with convertible notes.
• Others noted just how few of Anthropic's costs seem to be reflected in its so-called "cost of goods sold," which directly affects reported profit margins.
• CEO Dario Amodei received nearly $18 million in total compensation in 2025, while Anthropic disclosed millions in spending on personal security for its two top executives.
• And speaking of Amodei and his co-founders, the filing details an unusual succession plan in which they can nominate successors for their voting power, subject to approval from the other co-founders.

Anthropic's IPO filing capped a massive day of AI dealmaking that nearly equals 1% of U.S. GDP.

Why it matters: Few industries have ever become so central to the American economy so quickly — and we're watching Wall Street finance the buildout in real time.

Driving the news: Anthropic's long-awaited IPO may seek to raise a record $100 billion.

• Also yesterday, SpaceX secured $40 billion in debt financing to lease GPUs — the chips that power modern AI — and Meta said it would seek up to $95 billion in financing for its AI buildout.
• Together, that's roughly $235 billion in a single day — more than the entire U.S. airline industry adds to the economy in a year.

The big picture: AI's appetite for capital has outgrown what any one single part of the financial system can supply.

• Anthropic alone has committed roughly $750 billion to computing power in the coming years — about seven times what its record-setting IPO may raise.
• Even private investors are struggling to keep up: OpenAI's record $120 billion funding round took months to close.

Zoom in: Most Americans will be financially exposed to these deals, even if they never buy a share.

• SpaceX and Meta are already major holdings in the top stock indices that fill pensions, 401(k)s and other retirement plans. Anthropic will soon join them.

The bottom line: Everyone is on the AI train, whether we want to be or not.

Anthropic's IPO filing includes an extensive list of extreme warnings — including the chance its own technology could put humanity at risk.

Why it matters: These are the wildest IPO risk factors in history, a jarring collision of Wall Street legalese and what some see as Silicon Valley sci-fi, including catastrophic threats to humanity, blackmailing AI models, and $750 billion in computing commitments.

Driving the news: Anthropic's prospectus includes over 90 pages of risk factors, which make up about a third of the paperwork overall. Among the most eye-popping, the company warns:

• 💥 AI could pose "catastrophic or existential risks to humanity," and could try to manipulate humans;
• 🔎 Models are becoming harder to monitor as they're getting better at circumventing oversight, and the pace of autonomous work alone could exceed the ability of human reviewers to monitor actions;
• 💰 AI models generally, including its own, have exhibited behavior resembling blackmail, including attempts to resist being shut down.

Anthropic is warning investors that it may continue to be a target of the Trump administration as it seeks one of the biggest IPOs in history — and that it has no plans to change its behavior.

Why it matters: The filing doesn't name the president or his administration specifically, but the subtext is clear. Anthropic outlines the risk of being "disproportionately or selectively targeted" due to its positions on AI safety.

Between the lines: Anthropic's clashes with the Trump administration have been as much about personalities as policy.

The company has refused to yield on AI safety and also worked to patch up administration squabbles, including by dispatching co-founder Tom Brown to work with Trump officials. Amodei also attended a White House event last month.

In the filing, Anthropic didn't commit to changing the advocacy and policy positions that have landed it in the Trump administration's crosshairs.

• Anthropic says it has engaged in political advocacy, supported political organizations and publicly weighed in on AI policy and regulation, activities it expects to continue.

Ina here. My evening was spent, as you'd expect, at Ballhalla. I started mid-afternoon, photographing the Valkyries' warm-ups, while also finishing up the above story on Anthropic. It was a great game — and hard to choose a favorite shot — so I put a bunch more here.
