Bip 148 the UASF (user activated soft fork) will happen on August 1st and nothing can change that unless Bip 141 gets locked in before that date which is also a soft fork or SegWit 2x which is also a soft fork.

It will be a chain split and do we end up with 2 bitcoins?

I estimate there's a 10% chance for that to happen. Why do I think the chance is that low? Because most people in the community don't want 2 bitcoins, not even the miners.
