I'm curious to know if they generated this with Claude and what the prompt looked like.
Can someone help me understand how its "confidential" if they blog about it? Perhaps they simply mean the details of the S-1 are confidential for now?
Expect the token price to correlate with the stock price.
Of course that fundraise was the last one: [0], everyone getting ready to dump their pre-IPO shares on to you as China catches up with their open models.

Better to do it now than to wait a day longer and the tokens are not getting any cheaper here.

Obviously OpenAI will file for IPO certainly this month, or even this week in response both SpaceX, and Anthropic.

Then AGI will then have been achieved externally.

The powers that be are already planning to ban Chinese models.
Every post anthropic generates feels like misdirection and bad summarization using AI. There is no sense of who the audience for this post is for and includes a lot of redundant information.
The motivation for such a terse thing is pretty obvious given the way they’ve generally announced things. It’s drumming up interest with as much vagueness as possible.

It’s a classic tactic. If you are unable to show real data (why?), then just give as little information as possible so that people can just fill in the gaps based on their own biases.

I mean, look at the way Mythos was announced…too dangerous to release outside of select customers, but they’ve announced they’re adding Mythos capabilities now, so I guess the danger has passed? What changed? What risk mitigations have taken place?

With SpaceX, OpenAI, and Anthropic, we're likely to see 3 of the largest IPOs ever (by a wide margin) this year. Will existing institutional investors trim other positions to allocate a lot of capital for these mega listings or is this not a concern?
It also means the equity in any 2021-2023 minted unicorn is worth zero.
What does it mean to submit confidentially – what's the process there? I assume it be made public when approved by the SEC?
Time to short the market. We are at peak bubble.

> Time to short the market.

post your position for all to see if you're so confident. Time in market is way better than timing the market. I'd rather ride through a downturn, buying at the same pace i always do, and come out the other side than try to time it. Been there done that and i got burned every time.

If OpenAI and Anthropic eventually become public companies with trillion-dollar valuations, it will be interesting to see if their company ethos remains the same. With that much purchasing power, it's very tempting to gobble up competitors and raise prices.
There is a mad rush to get these IPOs out the door before the market sneezes.
Anthropic unlike OpenAI has reached an operating profit of 559 million, which is really telling. They've also been migrating enterprise customers to API pricing, which is likely part of why they've become so profitable.
Is there anything structurally to prevent a super wealthy buyer from guaranteeing this essentially -- moving money and debt around in order to essentially put a floor under the stock and guarantee buy rates until the retirement fund index purchasers have time to absorb all the shares at the artificially high price? Feels to me like this is almost guaranteed to happen -- ...
OpenAI, SpaceX, and this IPO: I don’t think there’s enough liquidity for all of them. Investors may pull money out of other investments, and hopefully that doesn’t cascade into a full market crash.

SpaceX submitted an amendment to their S-1 today[1]

The SpaceX IPO confuses me, with the kind of testing they do the stock price is going to be a roller coaster ride. Every splashdown with an explosion, even if planned, is going to impact the stock price. Are they hurting for cash? Why even IPO if you don't need the cash?
Where will it be listed? I am considering selling all my index ETFs in those markets until the this blows over.
Historically speaking, this looks like a fantastic time to sell stocks. Here's the Shiller P/E line graph:

Valuations are literally at 1999 levels, and that's before the coming IPOs. No wonder they chose this moment to IPO.

Got to dump this on everyone's SP 500 index fund before people figure out that there is a 95% drop in token usage when they are metered.
why did they raise 3 days ago? What's the benefit of doing this instead of going public right away? If it's just cash to pay for GPUs, can't they issue bonds or something?
Conspiratorially, it seems like a shotgun attempt at undermining the supposed OpenAI IPO later this year.

Also filing an S-1 doesn't actually indicate that they intend to go public "immediately," it just gives them the option to go public (probably in the near future).

After years of companies refusing to go public (looking at you Stripe), it's almost refreshing to see a hyped tech go actually IPO.
Companies rush to IPO because they think the price they are selling at is so high that it outweighs the painful nature of being a public company.
"Going public" means something completely different now, especially for these companies in the news (Anthropic, OpenAI, SpaceX, etc).

Going public used to mean selling a portion of your company for the capital required to grow. Ideally John Q. Public buys stock, the company grows, and they can sell the stock for more money.

These companies already have the capital required to grow from private investment, and already grew; they're behemoths. The act of "going public" are those private investors using the public market to cash out their investment. The exponential growth the public buyers are expecting to see has most likely already happened.

The days of capital light companies might be over for the near future.
Are dates set for this one or Space X? Who will “ring the bell first”, so to speak. I think the sequencing here matters more than it should.
Who’s going out of the gate first, Anthropic or Space X. Sequencing probably matters more than it should.
I know market will buy it, but where would it find the money to fund the stock purchase?

Would it crash other company stocks so that investors start selling and purchasing Anthropic shares, or how does it work?

I would assume that the outcome probability of people selling other companies to buy Anthropic/SpaceX/OpenAI has been priced in already.
Presumably, current Anthropic shareholders will buy buying other company stocks to diversify.
Did mythos write the S-1? It better not have been a human given the amount of hype they are pushing.
I think this IPO will be the real test of whether the concept of a Public Benefit Corporation actually holds up in practice. Don't mess this up, Anthropic.
As a potential PBC founder I am watching this closely for sure
(the) Public Benefit (the) corporation.
Right in time to get rich and externalize any fallout.
Up until this point, the potential for an AI bust blast radius was limited to corporate investors, but this is going to cause regular retail/401k investors to get exposure, which could have far bigger impacts on a downturn.

Not to mention the insane wake-up call it is going to be for these AI stocks when 3 months after they launch they have to start making earnings calls and showing their financials. That quarter-by-quarter pressure and scrutiny is no joke, and probably the biggest downside of going public.

I'm bullish on AI, but kind of bearish on any specific AI company. None of the initial big dotcom companies like AOL or Yahoo survived at the scale they briefly had.

Myself, I am preparing to bet on the short of my lifetime.
