Is there any news on the revenue sharing of GPTs?

I would bet the issue is that the back-end compute is insufficient* even for the current demand, and the last thing they want now is to increase the demand.
Frankly, right now I’m more concerned with the viability of the service. If it doesn’t work properly there will be no pie to share.

(*) As can be seen from the inaccurate responses of RAG-augmented GPTs.
“Hallucinations” were funny at the end of 2022; but not anymore.
