I don't know if I agree. Adyen is worth $45 billion euros (so $45 billion :) .) From their last annual reports, Adyen '21 GPV: $561B +70% YoY; Stripe '21 GPV: $640B +60% YoY but Stripe has ~2x take rate on Adyen because they are more PLG versus Adyen has many more enterprise customers.
So $74b is probably about right or maybe even low?
