The former working royal and failed Spotify podcast star could demand thousands of pounds for promotional posts on her page.
Complete with a celebrity-style username, Meghan's account (@meghan) could set the Duchess up for life, according to experts.
PR professionals tell SundayStar.co.uk that the Netflix star has already reached "micro influencer" level without even posting.
She's somehow managed to drum up more than 50,000 followers and, at the time of publication, hasn't made a single upload.
One source explains: "Meghan is already where most wannabe Molly-Mae's are already and she hasn't even gone public.
"We know she's always some sort of fame, so I'm sure she's keeping close tabs on her follower count and should be very surprised."
Insiders say Markle created the odd account before launching her now axed podcast, Archetype, but then left it abandoned.
Sources tell SundayStar.co.uk that Meghan is "coming back to Instagram soon" after seeing the success of her page already.
The move comes amid alleged marriage woes between Meghan and her husband Harry, with pals saying it would be "for the best".
The former working royals are allegedly "living separate lives" and the Duke is thought to be "spending time in hotels".
Insiders close to Meghan and Harry continue to insist that the claims are nonsense, calling the allegations simply "made up".
