According the the company, they intend rolling out to more regions, countries and websites as well as the other links which appear on their search results.
This AMP protocol will offer their users the ability to cache and serve cached copied AMP content already published on the web. It'll also provide a faster user experience on the platform.
As a publisher or content creator, you can enable your AMP published content within Bing by allowing the Bingbot to fetch AMP content and enable cross-origin resource sharing (CORS) for bing-amp.com domain.
Many AMP enabled sites and advertisers have already authorized the CORS sharing for the ampproject.org domain, but now it also needs bing-amp.com to the allowed list.
