Scenario 1 · Most likely · birth time unknown. This exact set of activations held for 7.5 hrs of the birth date. Values marked * held for only part of the day — choosing a scenario does not make them certain.

Built from the birth day’s gate and line transitions, which record when a planet changes gate rather than where it sits in the zodiac. The four Variable arrows and exact degrees need an exact birth time and are omitted.

About Sam Altman

Startup and investment career

Sam Altman became president of Y Combinator in 2014, where he supported early-stage technology companies and helped build a large startup network. He co-founded OpenAI in 2015 and has led the organization through its transition from a nonprofit research lab into a major AI research and product company.

OpenAI and AI leadership

OpenAI’s 2026 event materials identify Altman as co-founder and CEO, and the company’s September 2026 public statement also names him as CEO. Astro-Databank records his birth date and Chicago birthplace and quotes his time as “around 5 am”; this record preserves that approximation rather than treating 05:00 as exact.
