Elon Musk

Early life and education

Elon Reeve Musk was born June 28, 1971, in Pretoria, South Africa. His father Errol Musk was an electromechanical engineer; his mother Maye Musk was a model and dietitian. By his own account he was a heavy reader as a child - he has described reading the Encyclopaedia Britannica and large volumes of science fiction - and taught himself computer programming in his early teens, selling a BASIC game called Blastar to a magazine at around age 12.

He left South Africa at 17, taking Canadian citizenship through his mother, and attended Queen's University in Kingston, Ontario, before transferring to the University of Pennsylvania. At Penn he completed bachelor's degrees in physics and economics. He was admitted to a graduate physics program at Stanford in 1995 but left almost immediately to pursue internet ventures during the mid-1990s dot-com expansion.

None of this educational record includes a published IQ score. Strong early reading and self-taught programming are consistent with high ability, but they are biographical facts, not psychometric measurements, and they do not produce a specific number.

Companies and career

Musk's first venture, Zip2, a web software company, was sold to Compaq in 1999. He then co-founded X.com, an online bank that merged with Confinity to become PayPal, sold to eBay in 2002. With the proceeds he founded SpaceX in 2002 and invested heavily in Tesla, becoming its CEO and largest shareholder.

SpaceX developed the first privately funded liquid-fuel rocket to reach orbit (Falcon 1, 2008), the first commercial spacecraft to dock with the International Space Station (Dragon, 2012), and reusable orbital-class boosters that land and re-fly. Tesla brought mass-market electric vehicles to scale and became, for a period, the most valuable automaker in the world. He later founded Neuralink (brain-computer interfaces) and The Boring Company (tunneling), and acquired Twitter in 2022, renaming it X.

This record reflects exceptional ambition, technical literacy, capital deployment, and tolerance for risk. It does not depend on, or reveal, any particular IQ figure.

The IQ question and where the number comes from

The figure of about 155 - and other figures ranging from roughly 150 to 160 in different posts - appears widely on "celebrity IQ" list sites and social media. None of these sources cite a named test (Stanford-Binet, WAIS, Mensa-administered Cattell, etc.), a date, an examiner, or a documented administration. The numbers are presented without provenance.

This is the standard pattern for living-celebrity IQ figures: list-makers work backwards from a person's visible achievements to a plausible-sounding round number. That reasoning is psychometrically invalid. IQ is defined as a normed position relative to a population on a specific instrument; it cannot be inferred from a resume. A person can build several major companies without anyone ever having measured their IQ - and in Musk's case, no one publicly has.

Musk himself has not claimed a specific IQ in any verifiable record. Absent a published, named, dated test result, the honest answer to "what is Elon Musk's IQ" is: unknown - there is no measurement.

Why celebrity IQ numbers are usually wrong

Three recurring problems make figures like this unreliable:

• No instrument. A score has no meaning without the test it came from. A 155 on a high-ceiling research test is a different population position than a 155 on the WAIS-IV.
• No administration. Real scores come from a documented sitting: where, when, scored by whom. Celebrity figures have none of this.
• Reverse inference. Assigning an IQ based on someone being successful is circular - it assumes the conclusion (high ability) and dresses it up as a measurement.

For how real scores are produced and why they are not comparable across tests, see our methodology page and the historical IQ tests archive.
