I believe Bakkt accumulated a lot of bitcoins already. They are ready to play.
It seems that Bakkt was the cause of big pump from April this year, when price is jump from $4000 to $14000 in a relatively short time. They allegedly bought 100 000
BTC during that period, and as you say they are ready to play now.
People who are waiting that Bakkt launch new pump probably waiting in vain, how it seems now September 23 will not change anything in terms of price. It remains to be seen whether there will be any positive effects in the coming months, and depending on how this project will evolve, price impact may occur again when/if Bakkt start to buy
BTC again.
If this is for real then the whole market is a mess, If that's the only chance for the BTC price to rise, then, it's almost impossible for us to see the $10k mark again. only if your statement was true. but seeing the market now your statement is not a rumor anymore. since has fallen from $10k to $8k, it didn't rise again to $9k. as of now BTC and the other Altcoins are having some hard time to recover again. All red!!!
