Well, to make a long story short, Steve Ballmer is Jewish!
Since Steve Ballmer's mother is Jewish, and in Orthodox Judaism and Conservative Judaism, those with a Jewish mother (or those who underwent a halakhic conversion) are considered Jewish, then that makes him Jewish. His father is not Jewish.
Steve Ballmer (whose full birth name is Steven Anthony Ballmer) was born on March 24, 1956 in Detroit, Michigan.
Steve served as the chief executive officer of Microsoft from 2000 to 2014. He is the current owner of the NBA basketball team the Los Angeles Clippers.
