This assumes it's in Amazon's interest for there not to be.

Theoretically all companies under capitalism would want to become true monopolies because having competition means leaving money on the table, but in practice a duopoly or a de facto monopoly is preferable to skirt regulations and interventions. There is a good reason Google still props up Mozilla despite competing with them in the browser space.

It would also be interesting so see how many of the larger non-Amazons run on AWS.
