ARR vs ARR. Watch out for this one sly trick.

What’s in an acronym? How to read between the lines.

TL;DR

The acronym ARR can mean either Annual Recurring Revenue or Annualized Run Rate.
Annual Recurring Revenue refers to predictable income, like subscriptions.
Annualized Run Rate is a projection that may not reflect actual future performance and can be based on best-case scenarios.
Companies might use Annualized Run Rate to inflate their perceived financial success.
The shift towards open-source models by companies like ATT could impact Anthropic's revenue.
Netscape's historical rise and fall is presented as a cautionary tale about revenue projections.
Investors are advised to clarify which meaning of ARR is being used ('Caveat emptor').

Pretty good autogenerated cartoon — except that the sign the ref is holding completely misses the important fact that both terms have the same acronym.

Anthropic’s boosters are rushing to celebrate their ARR.

As they do, be mindful that the acronym ARR can actually mean two rather different things, Annual Recurring Revenue or Annualized Run Rate. (And65 otherthings, less immediately relevant.) You might think they are the same, but they are not.

What the boosters want you to think of is Annual Recurring Revenue. Annual Recurring Revenue is great; that’s things like subscriptions, which means next year likely to be same as (or better than) this year. Annual Recurring Revenuerecurs.

Annualized Run Rate, alas, means no such thing. It can mean as little as you did something like took your best month, multiplied by 12 and projected that your best month this year would be your average month next year. Thatcouldhappen. Or maybe your best month is NOT your typical month, and it will be better than your average month next year. You might in fact never have a full year that is twelve times your best month.

When people tell you Anthropic had this or that ARR, you really need to know which meaning they are talking about. They rarely tell you. But they really mean the latter.

Indeed, THE big issue for Anthropic is that the kind of revenue they were making in the second quarter of this year may well notrecur, at the same scale, next year, now that, in the aftermath of the collapse of tokenmaxxing, companies like ATT areincreasingly turning to open source models from other vendors, in order to save costs.

Speaking of meteoric rises that might not last, back in 1995 Netscape had revenue. Lots of it. Doubling every quarter. They went public. They were worth billions without having ever turned a profit. (Sound familiar?)

The astonishingrise of Netscape, before its fall.

And then things changed. Later that year, Microsoft offered a competitor, for free, and Netscapewas never the same, all but out of the game a decade later.

When someone boasts about ARR, be sure you know which term they are referring to. Caveat emptor.
