As "anyone can create a chain fork of Bitcoin at any time" and a SegWit2x hardfork in November 2017 is highly possible, a popular cryptocurrency exchange, BitMEX, clarifies its position on any and all potential hardforks.
The company claims that they will support the new coin only if there is strong replay protection and wipeout protection. It is detailed, that the administrative overhead of distributing any and all hardforked coins (including Bitcoin-based distributions like Byteball/Lumens) is prohibitive and BitMEX will not monitor or maintain balances of hard-forked coins.
It is our understanding that the SegWit2x proposal does not include two way transaction replay protection, enabled by default. Therefore BitMEX will not be able to support SegWit2x.
As such, BitMEX is not to support the distribution of B2X, nor will BitMEX be liable for any B2X sent to the company. This policy applies even if the SegWit2x chain has the majority hashrate.
According to the team, BitMEX considers any and all contentious hardfork tokens as altcoins. The .BXBT and .BXBTJPY indices will remain unchanged and will not include B2X.
