We'll have to wait and see. Any instant changes on the market will just be speculation on the news unless some big players have moves already planned for launch day but someone needs to confirm that actual BTC is used to settle contracts.
Nonetheless, we have always known the practices of the Wall street and some of their shenanigans, so in this case, I really would not want to be so optimistic with whatever comes out with Bakkt, until I get to see it happen. Bull run though is something I hardly believe will be happening anytime soon, with or without Bakkt.
Then it will go up pretty much guaranteed. The demand is already there, there's a lot of people that haven't invested yet because they are computer illiterates. There's a ton of boomers out there that simply aren't cut to be custodians of their own bitcoins, and this could finally be what helps them to get that 1% diversification into BTC.
At some point not owning BTC will pose a bigger risk than owning BTC, once this is widely understood FOMO will kick in and things like Bakkt will help everyone that doesn't know how to deal with computers to get themselves exposed to the market. We all know ideally everyone should learn how to deal with their own coins but that will never happen, so the more ways to get people on board the better. Im not bothered by it as long as contracts are bitcoin-settled.
