Clickthrough if you want the analysis and caveats

I could find an ARR for Cursor of $500M. Why do they they in this article that Cursor is loosing with this spending number ?

Ed's mentioned ARR in previous articles and it's not a "generally accepted accounting principle". They cherry pick the highest monthly revenue number and multiply that by 12, but that's not their actual annual revenue.

"Cherry pick the highest" is misleading. If your revenue is growing 10% a month for a year straight and is not seasonal, picking any other than the most recent month to annualize would make no sense.

Well people like Sam Altman have not been entirely honest and there's a reason they're not sharing their actual revenue numbers. If they could show they were growing 10% every month they would.

They are sharing their actual revenue numbers. That's what ARR is. Take the number and divide it by 12 and that's monthly revenue.
