I think the better question is how much more than $65B/year revenue they need to cover what they are spending on capex and model development. I would bet money their revenue in the next year is over $75B (vs $65B), but also that their amortized costs exceed their revenue.
I suspect it's more likely they will spend the extra money on hardware and infrastructure (data centers) either directly or via suppliers.
