i agree that the cboe data is more accurate. but from experience, the spy seems to be more on the mark than spx at opex. don't really understand why??

interestingly, there's a sizeable difference this month. spy suggests the strike would come in at about 900, while spx suggests 875 (as posted by stevieg08).

though, taking a closer look at the data, i think 920 is probably more likely. just my worthless opinion.
