Based on FT anecdotes from some years back, it is -- or at least used to be -- the case that Chase will bump the bonus only if all the other terms of the offer are the same. Since the 50K offer requires a lower spend (1K vs 2K), I would not be surprised if Chase declines to offer a match in this instance. Then again, stranger things have happened.
