What is Bill Gates's IQ?
Bill Gates's IQ is usually given as 160. No test result has ever been published. The estimate leans almost entirely on a reported near-perfect SAT score, which is a real data point but a loose proxy.
A quick, honest note. This number circulates online with no traceable origin. We publish it because you came to read it, and label it what it is: lore.
Where does the 160 number come from?
The SAT is the strongest thread here, and it is genuinely informative: on the pre-1995 scale a 1590 out of 1600 is an extreme result, and SAT scores do correlate meaningfully with general reasoning measures.
But "correlates meaningfully" is not "converts to". Conversions between SAT and IQ vary by which year's norms you use, and they lose accuracy exactly at the top of the range where the test runs out of headroom. Turning a 1590 into a confident "160" applies a precision the method does not have.
Gates has not commented on his IQ, and no proctored result exists.
How rare would a 160 IQ be?
If the 160 figure were literally true, it would be extraordinarily rare — rarer than1 in 31,560 people. That alone is a good reason to treat any confident-sounding celebrity IQ number with a raised eyebrow.
Too rare to draw — a grid with one highlighted dot in 31,560 would be a solid wall of gray.
What a score like this would mean
A 160 would sit in the very superior · gifted range — about one person in 31,560. Fill a large concert hall and you would expect nobody in the room to clear it.
