(Update: the majority of readers are getting Chase to match the new offer. We have heard a few who were unsuccessful.)
Reader Krivad reports that Chase is willing to match the lower spend requirement of $8,000 on the new Chase INK Preferred signup offer. The points offer is the same at 100k, and the spend was recently lowered from $15,000 to $8,000. Via secure message, Chase agreed to match the new offer for the reader.
At one point they stopped matching signup bonus offers, yet more recently they are typically willing to match. This particular case is interesting given that the bonus is the same and only the spend requirement changed. Hopefully everyone else has the same luck with Chase secure messaging agreeing to the match.
A reader notes that using this method it might even be possible to sign up now using a referral link and then having them match the lower spend. Again, YMMV.
