I believe there is no publicly available data that allows one to calculate the exact percent of new H-1B numbers used by a specific company. But if I go into USCIS's H-1 data hub, I can find some information. For FY-2022 Amazon had 12.5k petitions approved. But drilling into the data we see that less than 4k of those were for _new_ petitions - the others were extensions of existing petitions. 4k out of the H-1B quota is less than 5% (there are 85k new H-1B visas per year). But even that is an overestimate because a new employee transferring to Amazon will require a new petition but won't count against the quota. Overall, the best guess would be that Amazon use low single digits percent.
