What to know
- Anthropic generated over $2 in revenue per $1 of compute spending as of June, with a 19% adjusted operating margin and $3.9 billion in first-half free cash flow.
- The company has locked in massive non-cancelable compute commitments: $45 billion with Microsoft, $110 billion with Amazon, $121 billion with SpaceX, and $115 billion with Google.
- Anthropic warns that margins could compress as new compute comes online and that price competition, notably from OpenAI, threatens profitability.
- Anthropic is targeting an IPO the week of November 16, after reportedly delaying the offering twice amid market turbulence and AI safety concerns.
“as significant incremental compute is brought online in future periods, the associated expense will be recognized in advance of the full revenue that the compute will ultimately support, and we expect operating margin and Adjusted Operating Margin may compress in those periods.”

Imagine planning a $1.5T IPO but having the corporate equivalent of a poor credit score. That’s Anthropic. Blackstone previously expected Anthropic to earn an investment-grade credit rating before 2027. Now it expects a junk rating even after the IPO. A company’s valuation and its ability to repay debt are two different things. https://…

I wonder how ruthless some people will be to still try and make a huge profit from this IPO despite the major risks. Remind anyone of a certain banking crisis?

IPO to junk, what a way to start. Anthropic expected to receive high ‘junk’ rating from credit agencies following IPO - a double B range rating, the top tier of speculative “junk” grade.

Unlikely Anthropic able to repay. Take a look at their cost of production. GPU data centers which need huge capex and depreciate to near zero roughly every 3 years (though they try to trust-me-bro to 6). Even if you ignore the cost as gifted by Uncle Sam, they still runs into huge electrical consumption. You can't code away electricity. You can…

I feel even a "high junk" rating for debt issued by an LLM company is far too generous. A bond rated "BB" by S&P would be typical of the safest of the junk bonds. Historically, such bonds have about a 10% risk of default over 10 years: https://investmentgrade.com/bond-ratings/While I'm willing to believe that Anthropic common stock might somehow…

AHAHAHA the Anthropic share offering is likely to get a Junk rating, i.e. not investment grade wonder how that affects index listing https://www. ft.com/content/59383c7f-8d82-4 93f-bf01-d2e862a1018f (no archive yet worry)

By reading the comments I wonder if perhaps OAI & ANT are not going to be “model” companies and they are going to be the ones innovating in many fronts and cashing in for the benefits of those advancements…What I’m trying to say here is, what if, they are staying closed strategically so they keep their most advanced models close to their chest…

It doesn’t matter. These companies all believe they have infinite ROI. They’ll keep borrowing at whatever costs until they win or die.

200? I was thinking more of 5000. except you don't need that many programmers then. cut the free tiers, squeeze the money out of corpos and there you go, a profitable company. I can guarantee, the premium of 5k is well worth if for a corporation, comparing the code quality of claude to any of the competition

Even if all programmers on planet earth were paying Anthropic 200$ per month that would be super far from paying all the investment back.

Blackstone says Anthropic might not be able to reach investment grade when it goes public. It’s already said it will need to borrow money right away, like SpaceX borrowed $80B two weeks after their IPO. This means they’ll have to pay loan-shark interest rates for money they couldn’t afford to borrow in the first place. WHAT COULD POSSIBLY GO WRONG…
