Birth data: 1985-04-22, unknown, Chicago, Illinois, USA; Rodden rating C.

Sam Altman was born on April 22, 1985, in Chicago, the oldest of four siblings, and grew up in suburban St. Louis. He studied computer science at Stanford for two years and left in 2005 to start Loopt. He has given his birth time only roughly, so the chart is cast for noon. Its most visible feature is the Sun at the very start of Taurus, caught between Pluto and Neptune.

## What is known and what is not

The date and city are not in dispute: April 22, 1985, Chicago. They are given by Wikidata, Astro-Databank and the Spanish outlet Hipertextual. The family later moved to Clayton, Missouri. The hospital is not known, so the coordinates are those of the Chicago city centre.

The time comes from Altman himself. Astro-Databank quotes his email of December 6, 2023, to the astrologer Jessica Josephine: "around 5 am central time!". The database's compilers hold a copy; the email has not been published. Astrotheme gives the same time from the same email, so it is not a second, independent source.

Astro-Databank rates the time A, because it comes from the person himself. But "around 5" is a rounded time, and under our rule a rounded time gets [Rodden rating](/en/methodology#rodden) C and does not become the main time. There is a practical reason too: at 5:00 a.m. the Ascendant sits at the very start of Taurus, while for a birth before about 4:58 it is still in Aries. Even the Ascendant sign is not secured by this time, so 5:00 a.m. stays a version.

The chart is cast for 12:00 noon Central Standard Time (CST, UTC-6). Daylight time in the US began only on April 28 in 1985, so Chicago was on standard time on April 22. The chart has no houses, Ascendant or MC (more on [charts without a time](/en/methodology#unknown-time)). The Moon's sign is not certain either: at noon the Moon stands in the last minutes of Taurus and enters Gemini just after, so this reading does not rely on the Moon.

## The Sun between Pluto and Neptune

The Sun at 2°32′ Taurus is in [opposition](/en/aspects/opposition) to Pluto at 3°23′ Scorpio with an orb of 0°50′. The Sun forms a [trine](/en/aspects/trine) to Neptune at 3°31′ Capricorn, orb 0°59′. Neptune and Pluto are in sextile with an orb of 0°08′. That sextile is generational, but here the Sun is tied to both of its ends, which turns a generational theme into a personal one.

Tradition reads the Sun opposite Pluto as a will that works through struggles over influence and control, and the trine to Neptune as the ability to hold a large picture of the future and draw others into it. The Sun in Taurus adds patience and practicality.

In the noon chart the tightest aspect is a minor one: the Sun is [sesquiquadrate](/en/aspects/sesquiquadrate) Uranus at 17°35′ Sagittarius, orb 0°02′. Astrologers link this angle with restlessness and a pull towards abrupt change.

## Mars opposite Saturn

Mars at 27°27′ Taurus and Saturn at 26°28′ Scorpio are in opposition with an orb of 0°59′. This is the second opposition on the same Taurus-Scorpio axis, with both signs fixed. Classical astrology counts Mars in Taurus as in its detriment: action here is slow but persistent. Saturn opposite is traditionally read as restraint, obstacles and a demand to finish what was started, and the whole opposition as tension between drive and limitation.

Mars is also [biquintile](/en/aspects/biquintile) Neptune, orb 0°03′ at noon. Astrologers link the quintile family of aspects with inventiveness and a distinctive way of getting things done.

## Mercury and Venus in Aries

Mercury at 7°58′ Aries and Venus at 6°06′ Aries form a [conjunction](/en/aspects/conjunction) with an orb of 1°52′. Venus was retrograde that day. Tradition links Aries with fast starts, directness and the wish to be first, and the Mercury-Venus pair with speech that knows how to persuade.

The tightest major aspect in the chart joins Venus and Chiron at 6°00′ Gemini: a [sextile](/en/aspects/sextile) with an orb of 0°05′. Mercury also sextiles Chiron, orb 1°58′. The tense links go to Neptune: Venus is in [square](/en/aspects/square) to Neptune with an orb of 2°34′, and Mercury squares Neptune with an orb of 4°26′. Astrologers read a square to Neptune as a tendency to idealise and a blurred line between a plan and what already exists.
