AWS uses predictors / models for this when you are on serverless and automatically allocates instances for you ahead of time.

No one needs 10,000 machines.
They likely have scale issues and cannot scale their database quick enough so they planned for the worst spike possible which is likely for a hour on cyber Monday.
At Stripe's scale, I doubt you could accurately forecast demand for a weekend like Black Friday. Last year's sales are just a data point; what matters this year is consumer confidence on a global macroeconomic scale. Who knows what that translates to?
