Google AMP is dead! AMP pages no longer get preferential treatment in Google search.
Google say:
The Top Stories carousel feature on Google Search will be updated to include all news content. This means that using the AMP format is no longer required and that any page, irrespective of its Core Web Vitals score or page experience status, will be eligible to appear in the Top Stories carousel.
We’re also bringing similar updates to the Google News app, a key destination for users around the world to get a comprehensive view of the important news of the day. As part of the page experience update, we’re expanding the usage of non-AMP content to power the core experience on news.google.com and in the Google News app.
Additionally, we will no longer show the AMP badge icon to indicate AMP content
