Speculation wise, people are over Bakkt already. They want to see it go live and turn over some impressive amounts.
Bakkt has done all the buying of Bitcoin already, so people shouldn't expect them to influence the price in any shape or form. Only if there turns out to be so much demand, and for that reason have to start buying Bitcoin again, it might have some impact on the OTC market, but then again, with how liquid that market is I doubt it will reflect on the spot market at all.
It's funny how Bakkt on the same day of the correction from over $10,000 to $9300 they
Tweeted that they will start offering secure storage of customer's Bitcoin to prepare for the launch on September 23. They for some reason always make announcements just before/after a significant price movement.
