What kind of explanation do you think you can get? Somebody bought a ton of 3.0 puts.
Maybe somebody is short C and sold puts against his position? Hard to say if this is a directional bet.

Maybe a new long waiting last minute to buy puts at the lowest price. Justified of course by the belief on a high close with the lowest price. synthetic call.
