Update: This is actually fake news as Chase is using dynamic end dates to create urgency.
An e-mail for the Chase Ink Business Unlimited now clearly states the sign up bonus will end on September 20th, 2018.
Often these aren’t hard dates and they end up being extended but something to keep in mind if you’re eyeing up this card/bonus. I suspect if it does disappear the bonus would drop down to $300.
