IIF Certified Assessment
Altman’s IQ is quoted anywhere from 135 to 170 online, a thirty-five-point spread built entirely from career outcomes rather than any administered test. What is documented is a Stanford computer-science enrolment he left after two years, and what he built afterward.
Every figure attached to Altman is inferred backward from these outcomes, not measured. Business and research leadership correlate with intelligence loosely at best, and a record this concentrated in one career says less than a broad-based test would.
Set the claim aside for a moment. If someone genuinely scored in this range, here is what that would represent.
Average is 100 by construction, and about two-thirds of people fall between 85 and 115. Take the test to place your own score on this scale.
| Score range | Classification | Share of people | What it indicates |
|---|---|---|---|
| 85 – 114 | Average | ~68% | The range most people fall into. |
| 115 – 129 | Above average | ~13.6% | Roughly one person in seven. |
| 130 – 144 | Gifted | ~2% | The threshold most high-IQ societies use. |
| Above 144 | Highly gifted | ~0.1% | Figures above this range are extrapolated from the curve rather than measured. |
Percentages are approximate and describe a normal distribution. The same number means different things on tests with different standard deviations.
Thirty questions gives you a measured position on this exact scale — your score, your percentile and the ability breakdown behind it.
Find out in 30 minutes →Sam Altman was born in Chicago in 1985 and raised in St. Louis, Missouri, attending the John Burroughs School. He enrolled at Stanford University in 2003 to study computer science and left in 2005, after two years, to co-found the location-sharing startup Loopt with Nick Sivo.
Loopt was acquired by Green Dot Corporation in 2012 for $43.4 million. Altman became president of the startup accelerator Y Combinator in 2014, succeeding co-founder Paul Graham, and stepped down in 2019 to work full-time on OpenAI, which he had co-founded as a nonprofit research lab in 2015.
On 17 November 2023, OpenAI’s nonprofit board removed Altman as CEO, citing a lack of candour in his communications with the board. President Greg Brockman resigned the same day, and within a week — after employee and investor pressure and the threat of a mass resignation — Altman was reinstated with a reconstituted board.
By Elora Mercer, Celebrity Research WriterFigures checked by Leon Falkner, Data & Research AnalystThe estimate above rests on this record. Every entry here is a matter of public fact, which is more than can be said for the number itself.
Following a claim back to its first appearance is the part almost nobody does — and it is what most people are actually asking.
Altman’s number gets searched for a reason his page-mates don’t share: he runs the company most responsible for the current interest in what machines and minds can and can’t do. That attention gets pointed at his own intelligence by a kind of reflex, with no more evidence behind it than any other tech founder here.
The pattern matches Elon Musk, his co-founder and later rival at OpenAI — both left an elite computer-science track without finishing it, and both have had a number assigned to them that traces to their companies rather than to any test. It also matches Mark Zuckerberg’s case closely enough to place them within a few points of each other: an Ivy-calibre admission, an early exit, and outcomes read backward into a score nobody administered.

One site states outright that its figure is inferred from career achievement, not a test result.
No school, clinical or standardized test result for Altman appears in any source we could find.
The figures that circulate for Sam Altman, what we were able to confirm, and where the two diverge.
Numbers between 135 and 170 circulate on “smartest tech CEO” listicles and IQ-aggregator sites, with 170 the most frequently repeated figure.
We found no record of Sam Altman ever taking a standardized IQ test, and no site publishing a number for him cites one. One aggregator states its method plainly: the figure is derived from “Stanford CS admission plus career outcomes,” not a measurement. That is an estimate dressed as a fact.
A thirty-five-point spread, and the same non-existent source underneath every number in it.

No test result exists. Numbers between 135 and 170 circulate online, all inferred from his career rather than measured. Our 138–150 range is an achievement-based estimate.
It has no traceable source. It is the most frequently repeated number on aggregator sites, none of which cite a test, a school record or a named study.
No. He enrolled in 2003 to study computer science and left in 2005, after two years, to found Loopt.
He co-founded Loopt (sold to Green Dot in 2012 for $43.4 million) and served as president of Y Combinator from 2014 to 2019.
OpenAI’s nonprofit board removed him on 17 November 2023, citing a lack of candour in his communications with the board. He was reinstated about a week later under a reconstituted board.
The same pattern as Elon Musk and Mark Zuckerberg: an elite computer-science track left unfinished, and a number inferred from the company built afterward rather than from any test.
You can find out in about fifteen minutes. The IQ Metrics assessment is 30 questions, scored on the same 100-mean scale used throughout this page, so your result and the estimate above are at least expressed in the same units — one measured, one inferred. Once you have a number, the leaderboard shows where it would sit, and how we score and norm it explains the benchmarking.
From the documented record rather than a test — the method is named above and set out in full under how we read a number. Compare it against the other business & tech profiles, starting with Steve Jobs.
