AWS’s market position is deteriorating rapidly. They’re now at just over 30% of market share compared to 50% in 2018. Meanwhile the trend right now is big companies pulling their core infra out of the cloud and into their own datacenters. They also haven’t managed to launch a game-changing best-in-class service or feature in 5 years outside of maybe custom lambda runtimes.

I wouldn’t be surprised if this AI wave pushes azure into the forefront.

They're not doing fine as evidenced by the loss of value in their share price. AWS on its own isn't big enough, nor still growing enough, to justify a massive valuation anymore. And the web storefront is suffering too. Amazon simply isn't doing that well at the moment any way you look at it.
