Bitfinex has allowed for future tradings on the new upcoming hardfork. As of today here are the stats.
So so far it shows bitcoin being worth at about 3452.8 and segwit2x fork (S2X) at 1199.0
Below that it shows Bitcoin retaining 75% of its price and Segwit2X coin at 25%. This isn't to be taken too seriously as volume is pretty low and we have a ways to go till the november hardfork. Will continue to monitor this as the hard fork approaches!
