It's possible. Though, OF is behind Cloudflare. Assuming they're using R2 buckets for object storage of media there is no egress fees, which could be saving them lots of money if they're caching properly.

Looks to be anual costs of around 700Million, excluding their 'talent' payouts. They have 45 employees, say at 200k each. Let's call it 10 million.
Rent, utilities, etc, financing.. let's say 10 million annually.
That leaves 650 million in storage, hosting, bandwidth, security/cloudfaee, etc...
Now, I can do the math, but I have no idea what kind of viewership/user base they have. But on 6B in revenue, it must be massive.
