With the introduction of Instant Articles, Facebook introduced their way to allow the publishers to monetize their content/articles.
One thing must be understood, that you don't make money from Instant Articles directly, but rather with Facebook Audience Network and custom ads.
To answer the question on how much you make from the Facebook Audience Network, depends on many factors, especially the eCPM (effective cost per mille/Revenue per 1000 impressions).
If your eCPM is 3 then you will probably make $3 for every 1000 impressions. eCPM again depends on a lot of factors like the CTR (click-through rate), CPC (cost per click), your website niche and the geographic location of your traffic.
Going by this calculation to make $5000 at an eCPM of $3, you would need to drive a minimum of 1.66 Million monthly views to your content.
It is very important to focus on the quality of you traffic and the niche traffic, as they are direct factors on which the value of eCPM depends.
