In Trump's Manhattan Hush Money Trial, two jurors who were sworn in have already been excused and replaced. There is now a full Jury of 12, but a few more alternates will still be sworn in in case any of those 12 need to also be replaced.
While the jury is anonymous, reporters in the courtroom have told us a fair bit about them. See NYT and NBC.
If we learn that another juror has left the jury, this market will resolve to that juror. If there is reporting of multiple jurors leaving the jury at the same time, this market will resolve to an equal split of those jurors. The "other" option exists to cover unknown unknowns, and should resolve "no" in most scenarios.
