After short amount of time, Cruz perhaps becomes very wealthy (6)
I believe the answer is:
minted
'very wealthy' is the definition.
'after short amount of time cruz perhaps' is the wordplay.
'after' says to put letters next to each other.
'short amount of time' becomes 'min' (short for 'minute'; 'short' indicates an abbreviation).
'cruz perhaps' becomes 'ted' (US politician Ted Cruz).
'min' next to 'ted' is 'MINTED'.
'becomes' is the link.
(Other definitions for minted that I've seen before include "Coined" , "Manufactured coins" , "Struck (coins)" , "Rich" .)
