What does Anthropic’s chatbot, Claude, think about the big initial public offering ?
Nice work, Claude! I laughed out loud at this. Looks like Anthropic’s AI chatbot demonstrates at least a basic understanding of journalistic ethics.
An important caveat. Don’t worry, Claude, I’ll be doing that.
OK, onto the summary of Anthropic’s filing, which Claude boiled down to these five sentences.
Anthropic is growing at an astounding pace, and Claude’s synopsis actually undersells that fact a bit. When comparing Anthropic’s first-half sales this year to its first-half sales last year (a more apples-to-apples comparison), the company’s revenue grew 1,300%. Of course, no one expects that pace to keep up as the AI business matures, and Anthropic uses the word “slow” 36 times in its prospectus.
Right. This is one of the two big concerns about investing in Anthropic: The amount of money it has committed to spend on computing power (and cloud services — you left that part out, Claude) is worrisome, making Anthropic (and any AI hyperscaler) a particularly risky bet. It spent $8.9 billion on computing power last quarter alone.
So risky that the company dedicated 94 pages to risk factors alone (more on that in a second).
Claude’s note about the structure is accurate and important. But is it really that unusual? OpenAI (famously) has a similarly oddball corporate structure. Mark Zuckerberg controls the majority voting power for Meta. Elon Musk controls most of SpaceX.
Nevertheless, the point is valid: We’re being asked to put a tremendous amount of faith in Big Tech leaders that they’ll be good stewards of the technology.
“AI safety incidents” may be the understatement of the millennium. For example, on page 46 of its prospectus, Anthropic said AI sometimes exhibits manipulative behavior that can resemble blackmail. Four pages later, Anthropic notes the amount of damage AI could do may be so catastrophic that no insurer would pay out — or even write a policy — to cover such an existential threat to humanity.
That’s not, like, run-of-the-mill safety stuff.
Yes, those things are left blank intentionally. We’ll get those numbers just before the IPO.
Claude then broke down the IPO filing into several sections, starting with “The numbers, in plain terms.” And Claude did a nice job here contextualizing some of the report’s more eye-popping numbers.
Yep. The headline compute expense growth got everyone’s heads turning: Up 2,832% between the first half of 2025 and the first half of 2026. But, as Anthropic’s overall revenue exploded, those costs grew comparatively more manageable, and the company turned a decently large operating profit in the second quarter.
Then Claude included a section called “The spending commitments (likely the biggest risk story).”
That’s a helpful note at the end — a couple of analyst notes I received added all those commitments together and came up with a number nearly double what Anthropic said it had promised, so the actual number may come in less than the sum of the parts because of some overlap.
Regardless, it’s a lot of money, and it’s risky no matter how demand for Anthropic’s services shake out: Those commitments are fixed, so if demand comes in lower than expected, Anthropic still has to pay all that. But Anthropic also noted that its compute providers aren’t able to offer as much power as the company desires — and many of those companies are direct competitors with Anthropic. Claude didn’t mention that important detail, even though it highlighted Anthropic’s spending as the biggest risk.
And in a section called “Disclosures worth reporting,” Claude detailed some of the company’s “safety incidents.”
Claude here is detailing an incident Anthropic mentioned on page 47 of its prospectus. But what about the page before, when Anthropic mentions a somewhat bigger risk factor AI could pose: “catastrophic or existential risks to humanity.”
I dunno, maybe it’s just me, but that feels worth a mention.
Overall, this is a pretty good summary.
Claude’s synopsis quickly pulled out all the relevant numbers from a 318-page document and did some surprising calculations I wouldn’t have thought to do to arrive at an implied valuation. And I love how it understands journalistic ethics.
But it struggled to contextualize the IPO in a way that drove home what’s so important about it. It undersold both Anthropic’s stunning growth and its massive loss & spending commitments. Most importantly, it failed to capture how severe the risk factors are and the comically large amount of space dedicated to them.
In other words, Claude excelled at the “what,” but a human expert would have done a much better job at the “why.”
If a writer had filed the “story” Claude shared with me, I’d have spiked it.
