It's actually more like 100x their current revenue; they stated last week[0] that they have spending commitments for $1.4T of compute.
Or, well, they stated that the TCO of the compute they have commitments for is $1.4T, which is a somewhat strange phrasing. I assume it's due to it being a mix of self-owned vs. rental compute, and what they mean is the TCO to OpenAI rather than the TCO to the owner of the compute.
