About Bill Gates
Bill Gates, co-founder of Microsoft and one of the world's most successful entrepreneurs, has an estimated IQ of 150–160. Gates scored 1590 out of 1600 on the SAT (old scale), suggesting exceptional cognitive ability. He dropped out of Harvard — not because he struggled, but because he saw an opportunity in personal computing that couldn't wait. Gates is known for his ability to rapidly process complex information, his deep technical knowledge, and his systematic approach to problem-solving.
What an IQ of 150–160 Means
Gates represents the archetype of high IQ combined with relentless execution. His SAT score alone suggests an IQ around 150+. But his success at Microsoft came from combining cognitive ability with business strategy, competitive instinct, and the ability to identify and exploit market opportunities. In his philanthropic work, Gates applies the same analytical approach to global health and education that he used to build Microsoft.
