Taking a further look: while just looking at the most popular options' strike prices, there are 10,141 put options at a strike price of $500/share, and there are 7,736 call options at a strike price of $550/share. I find looking at the spread with all the details interesting. I suspect most of the people modeling this are paid to keep it proprietary. I wish I had the talent, because it could probably start a fascinating discussion on a site like this.

EDIT: put option numbers were incorrect. Time stamp is ~6:30 PM EST.
