Looks like GDAX for one is not participating in case of a hard fork: https://blog.gdax.com/uahf-a703b6a13115

Coinbase isn't either, judging by the mail they sent to all their customers, and by https://support.coinbase.com/customer/portal/articles/284421... .

Makes sense. (as far as I know) GDAX = formerly Coinbase Exchange

Formerly would be incorrect. While owned by Coinbase, GDAX is a different project, not a continuation of the original CB exchange.
