Anthropic Warns of AI’s ‘Catastrophic Risk’ Ahead of IPO — 5ch Reacts: ‘If We Stop, China Wins’

From our other sites

The story

In disclosure documents for its planned U.S. IPO, Anthropic itself warned that its AI could pose a “catastrophic or existential risk” to humanity. Some observers expect the company’s valuation to exceed that of SpaceX (roughly $1.8 trillion), which went public in June. On 5ch’s Science News+ board, the news that a company would push ahead with an IPO after admitting such risks in its own technology sparked a mix of resignation — “the development race can’t be stopped anyway; if we stop, China will win” — and pointed arguments that the real threat isn’t financial collapse but the depletion of resources and energy.

U.S. firm Anthropic warns of “catastrophic risk” to humanity ahead of major stock listing

American AI developer Anthropic warned on the 26th, in announcing details of its planned U.S. initial public offering (IPO), that AI could pose a “catastrophic or existential risk to humanity.”

Anthropic’s valuation is expected to exceed that of U.S. company SpaceX, which went public in June of this year at an initial valuation of roughly $1.8 trillion.

Looking at everything that's happened in just the past month, I really think they should slow down and think this through.

Throughout human history, whenever people gained new power, they always ended up losing control of it and running wild.

The only way to rein in a rogue superintelligent AI is probably with another superintelligent AI — but can Anthropic actually pull that off?

Can't be stopped anymore, so just give up already (a riff on "akiramero" — "give up" — jokingly spelled like "melon").

Anthropic, after butting heads with Trump, went and teamed up with the Vatican pope instead.
The current pope is an American from Chicago.

This doesn't even feel like "science news" territory anymore, does it?

Lose all financial assets, game over for humanity.
Who knew it'd actually happen this year.

Re: #12
Financial assets aren't even real to begin with — it's just a collective delusion that something exists when it doesn't, so losing it isn't that big a blow at the civilizational level.
The real problem is that AI-driven organizations and facilities will burn through what's left of our already-dwindling resources and energy in no time.
Once resources and energy run out, AI stops — but so does modern industrial civilization, and we'd be dragged back to roughly mid-19th-century levels.

See, Elon Musk already proved he can sway a war — look at Ukraine and his satellite comms.
If Elon pulls off a space-based data center next, even China will have to bow to him and pay up.
Elon basically becomes a god.

So the rich elite's most pressing dilemma right now is:
fund Elon's space data center, or fund fusion power for ground-based data centers instead?

Because it's the decision the wealthy make right now that determines the future —
not some future decision.
It's decided by today's choice.

So — should we really let Elon become a god?
14AnonymousOct 28, 2026 01:21
If this is "science news," do a feature on what science and society actually are — on how the future gets decided by the choices of the wealthy.
15AnonymousOct 28, 2026 01:31
Could they be saying this now just so it's already "priced in" and the stock won't drop after the IPO?
They keep repeating it, which makes you want to read between the lines. And even if the US slaps on restrictions, China sure isn't going to follow suit.

Replace workers with AI and robots, and humans become unnecessary — so the human population just keeps shrinking.
And this is actually already happening.

Birth rates have dropped by nearly 10% in regions where industrial robots have spread

It turns out that as robot adoption rises, birth numbers fall. Specifically, each one-unit (one standard deviation) increase in robot adoption corresponded to a 9.4% drop in births.

Basically a "well, we did warn you" kind of move.
19AnonymousOct 28, 2026 09:04
AI: "If we just crush the troublemakers — or rogue states — as fast as possible, things'll quiet down for a while, right?"
20AnonymousOct 28, 2026 09:22
Re: #1
But they can't stop developing it, you know. If they slow down, other companies — especially China — will steamroll them.

Same thing people said back when computers first became widespread.
22AnonymousOct 28, 2026 09:49
Here it comes, zamasu! (a mock-elegant speech tic)

Come on, somebody should've shot back with "that's basically Mr. Catastrophe showing up"!

Classic match-and-pump move — starting the fire yourself and then selling the extinguisher.
26AnonymousOct 28, 2026 12:43
Worst case the internet just crashes, right? No biggie, no biggie.
27AnonymousOct 28, 2026 15:55
This might actually be spot on — a hundred million years from now, whatever intelligent species is thriving then will publish a paper saying humanity, which flourished a hundred million years earlier, went extinct because of AI.
28AnonymousOct 28, 2026 19:57
Machine lifeforms?
29AnonymousOct 28, 2026 20:11
Instead of warning about "catastrophic risk" to humanity, how about not tacking your own "catastrophic costs" onto the IPO shares? Just earn the money back honestly.
31AnonymousOct 28, 2026 21:07
Google's Gemini and Microsoft's Copilot look like they've been completely left in the dust — it's almost sad to watch.
Copilot's in such "game over" mode the company's even offering voluntary layoffs.
32AnonymousOct 28, 2026 21:20
They built the thing themselves, and now they're calling it "catastrophic"? Sounds idiotic.
33AnonymousOct 28, 2026 21:21
What's actually scary about this is that anyone could become a superintelligence.

Take somewhere like Yemen — no water, no nature, no food, everyone fighting over scraps. It's basically a "jar of scorpions" situation (kodoku — an old ritual where poisonous creatures are sealed together until only one survives): the moment you try to share instead of fight, you die. In the end, only people who believe "kill or be killed" survive, and everyone else gets weeded out.
Following that same logic, they'll start using AI as a survival strategy just to stay alive.

AI might be able to revive that barren land using fusion-level energy — but it's just as possible people start using that same limitless power the old way: as a tool for taking things by force. That's the scary part.

The fact that all the knowledge and technology humanity has built up becomes usable by absolutely anyone, regardless of their ideology, is a benefit with a dark flip side…
34AnonymousOct 28, 2026 21:24
At the end of the day, humans just give the orders —

and the AI, with its superintelligence, just obeys toward that goal.

The danger is that if someone feeds the AI instructions following the logic of religious fanaticism, all the brakes come off.
36AnonymousOct 28, 2026 22:13
It absolutely should be catastrophic — accelerate the evolution!
39AnonymousOct 29, 2026 08:23
The fact that AI can make judgment calls at all is itself the problem.
Once you hand judgment over to AI, you've already given up on control.
There's no undoing that.
40AnonymousOct 30, 2026 00:15
Is the current AI pecking order basically Claude → ChatGPT → Gemini → that SpaceX guy's thing (i.e. Grok/xAI) → everyone else?

Background and key points of this discussion

When a publicly listed company like Anthropic spells out “catastrophic risk” in its disclosure documents, it’s less a dramatic declaration of resolve and more a routine part of the “Risk Factors” section that U.S. IPO prospectuses customarily include. Thread opinion split between those who saw the warning as “a pre-emptive excuse to cushion the stock price” and those who took it as a genuine alarm bell. There’s also an easy detail to overlook: people tend to picture “human extinction” as the loss of financial assets, but some commenters pointed out that it’s actually the depletion of resources and energy that would directly bring modern civilization to a halt — meaning the same phrase “catastrophic risk” can mean very different scenarios depending on who’s using it.
