How promoter hold their stock in demat

Difference between how individual and promoter hold their share in demat account.

Individual hold demat account through broker. I want to know how promoter hold their stock in demat account.

As an individual does with broker, Promotors might hold Demat account through their bank. One can also open Demat account without broker, maybe that’s the route they take and do transactions off market.

as far I know ; one can only open the demat account through a DP only !

I will give you example for better understanding.

Facebook Invested in Jio Platforms and got 9.99 stake in Jio.

Where or how does facebook hold this shares ?
