For implementing AMP, is it compulsory that the website needs to support HTTPs ?'.

In order to get the AMP version of my website show up on the SERP, is it a complusory factor that my website needs to support HTTPs.

[O2C]

Shouldn't have thought so. I have implemented it on a few of my clients sites which aren't HTTPS and they are being indexed fine.

Most of the sites that use AMP pages are things like news article sites etc. which don't really need to be HTTPS as they are not saving any of the customers secure information.

No, in order for your AMP pages to be indexed you do NOT need to implement HTTPs on your website.

[Martijn_Scheijbeler]

Definitely not, AMP is more a markup then something that requires it needs HTTPS.

My understanding is that AMP pages don't need to be HTTPS themselves, but the resources they link to often need to be (see https://www.ampproject.org/docs/reference/validation_errors.html). I think that is so it can be cached by Google and served on an HTTPS site without problems.
