Anthropic is rated junk. That is better than it sounds.
A small agency graded the company in June. It only came to light when the Financial Times read the paperwork — and the word does less work than you would think.
Anthropic has a credit rating of BB+, awarded in June by the Kroll Bond Rating Agency. Nobody announced it. It surfaced in mid-October when the Financial Times went through the documents.
Junk is the industry's own word, and it is a bad one.
Ratings run in a ladder. Above a certain rung you are “safe”; below it you are “junk”. BB+ is the top rung of junk — one step below the line. It does not predict failure. It says lending here is less safe than lending to a water company.
What a credit rating is for
A rating is not a view on whether a company is good. It is a view on whether it will repay money it borrows, and it exists because the people lending are not in a position to check for themselves.
The rung matters because it sets the price of borrowing. One step below the line and you pay noticeably more interest.
Worse, some investors are not allowed to lend below it at all. Pension funds and insurers are often barred by their own rules. At these sums, one step is a very large annual bill.
How this one was arrived at
This is the part worth knowing. Kroll did not build a full financial model of the company. It used a quicker scoring method.
And it worked from what Anthropic chose to hand over: three months of revenue, a profit figure, a projection of the year ahead, and its own forecast for the next quarter.
What it did not get was cash flow: whether more money comes in than goes out.
That is the figure that matters most, and the analysts had to estimate it. A grade built on a guess at the most important number is a grade with a wide margin around it.
And it is not the rating that will count
Kroll is a smaller agency than Moody's, S&P and Fitch, and it is those three who will set the formal rating once the company lists. The Financial Times reported that Morgan Stanley and Goldman Sachs, advising on both the Anthropic and OpenAI listings, have been lobbying the big agencies for investment grade.
That lobbying tells you what the notch is worth.
The idea to take away
A credit rating answers one narrow question — will the debt be repaid — and says nothing about whether the technology works or the company will win. Treat it as a price tag on borrowing, not a verdict. The interesting detail here is not the grade but the gap in the paperwork: the figures the agency most needed were the ones it had to guess.
