Aside from the companies themselves, no-one knows what will happen, and I think even they don't know for certain.

If Comet is drip selling their IG6 shares then they IG6 is obligated to notify the market via a change in substantial shareholding notice once there has been a 1% or greater change in their holdings since their last update. Eg if they held 24.1% at last notice given on 1/10/2024 and had been drip selling since then and their last sale took them to 23.1% holding then a change in substantial holding is required. IIRC they have three days to lodge after the date that transaction occurred.
