There is nothing on PACER but I doubt PACER would show anything due to the size of these cases. I would expect a press release and a big deal.
The timing would be right for stuff to start leaking. This settlement is with multiple states and multiple Federal offices, tons of legal teams, etc.
I have seen weird price action before on these sorts of cases and they usually turn up true in hindsight. I won't trade on it but I can see that others have.
