Vivek is smart and cunning (say what you will about whether he's trustworthy or not):
He didn't waste too much time or money on the election (obviously knew he wasn't going to be president this time around) and left the second that Trump considered him worth attacking, but he got his name out there in a generally positive way in the Trump voter base, caused some disruption against Trump's enemies, and made the republican party sweat a bit. Plus Trump might consider appointing him to a position if he wins, which would definitely bolster a future political career. He also realizes where the wind is blowing in terms of right-wing populism and didn't make any huge mistakes.
This was definitely not a serious bid for president from him.
