We expected Google to start showing non-AMP pages in the top stories carousel in mobile search last Thursday. It seems like as of yesterday, Monday afternoon, Google began to show non-AMP pages in the top stories carousel.

Glenn Gabe noticed it on Monday afternoon and posted screenshots of it on Twitter, I was able to replicate it, finally, and here is a screenshot and GIF of it in action:
Notice, some of those listed do not have the AMP badge, and when I clicked on them, they did not go to an AMP page.
Here are more screenshots from Glenn:
Here are screenshots from others:
Keep in mind, many AMP pages will continue to show as long as publishers continue to use AMP.
