According to the Chase website, the 100,000 signup bonus offer for the Sapphire Reserve credit card will end on January 11, 2017.
The Points Guy is reporting that the bonus will be dropping by half, to 50,000 points. It’s not clear if in-branch applications will also have bonus offers reduced. I suspect they will at some point also.
If you were waiting for one last good reason to apply, your time has come. Don’t forget that the Sapphire Reserve is subject to Chase’s 5/24 rule. Good luck!
