AFAIK there is not enough publicly available data to answer this question. But total_corporate_revenue(1) / total_corporate_spend(2) is an almost nonsensical way to calculate that number.

(1) which is not the same thing, at all, as the total amount customers are paying for rides

(2) which is not the same thing, at all, as the cost of providing all uber rides

Why not?

Because they are two different numbers in the report in question. Maybe go look at it?

Any percentage given is very misleading. In nearly all cases, Uber will make a profit when you take a ride. However, they built such an expensive company (huge R&D department, zillions of free coupons, ads everywhere) that they cannot pay for it without making a loss.

If they suddenly had 10x as many rides or would shed coupons and R&D, they'd probably be profitable. But they'd also lose their edge they hope to have over Lyft & Co.

NB: There are of course areas where they offer rides below the driver's cut, but that's probably rare after they exited China.
